The Main Features and Working Principle of Spring Cone Crusher Spring cone crusher: Spring cone crusher is the earliest cone crusher appearance in the world, and they are used widest and larger quantity crusher machine at present. With the improvement of the series of cone crusher, their structure is more perfect and the technology parameter is more advanced, so this series of cone crusher have excellent performance in the aspects of manufacture, installation, use and maintenance etc. Type of the crushing cavity is decided by the application of the ores. The standard spring cone crusher is used for intermediate crushing; the medium spring cone crusher is used for fine crushing; and the short head spring cone crusher is used for super thin crushing. Spring Cone Crusher Structure: This spring cone crusher consists of frame, transmission device, hollow eccentric shaft, bowl-shaped bearing, crushing cone, springs and hydraulic pressure station for adjusting discharge opening. Spring Cone Crusher Application: With advantages of reliable construction, high prod activity, easy adjustment and low cost in operation. Spring cone crusher is widely used in industries like metallurgy, construction, road building, chemistry etc, to crush many kinds of mid-hard or hard rocks and ores such as iron ore, limestone, granite, basalt, quartz etc. Spring Cone Crusher Working Principle: A cone crusher is similar in operation to a gyratory crusher, with less steepness in the crushing chamber and more of a parallel zone between crushing zones. A cone crusher breaks rock by squeezing the rock between an eccentrically gyrating spindle, which is covered by a wear resistant mantle, and the enclosing concave hopper, covered by a manganese concave or a bowl liner. As rock enters the top of the cone crusher, it becomes wedged and squeezed between the mantle and the bowl liner or concave. Large pieces of ore are broken once, and then fall to a lower position (because they are now smaller) where they are broken again. This process continues until the pieces are small enough to fall through the narrow opening at the bottom of the crusher. A cone crusher is suitable for crushing a variety of mid-hard and above mid-hard ores and rocks. It has the advantage of reliable construction, high productivity, easy adjustment and lower operational costs. The spring release system of a cone crusher acts an overload protection that allows tramp to pass through the crushing chamber without damage to the crusher. Spring Cone Crusher Main Features: 1. High productivity; high quality 2. Fewer spring conr crusher machine down time 3. Easy maintenance with low cost 4. Unique crushing ability in primary, secondary and tertiary crushing 5. Advanced safety system. The safety system of spring cone crusher acts as an overloading protection system that allows metal to pass through the crushing chamber so as not to damage the spring cone crusher. The safety system uses dry oil and water as two kinds of sealed formation to make plaster powder and engine oil separate to make sure reliable performance.

The Analysis of Chinese Crusher Development Prospects As country continues to expand domestic demands and increase infrastructure construction, this will drive the crusher industry of booming development. Because it is the source of all raw materials, and it can be imagined that productivity is how dare not for revenue without crusher. Crusher applications market is very wide, it including chemical industry, mining, construction and other industries. In China's most important application fields are cement industry, paving and mines, and it accounts for about 30% of the whole industry in these two industries. So crusher have good development prospect: 1. Crushers upgraded. Due to the small crusher life is three to five years, and the crusher for domestic change about 20% of the total demand crusher every year. Even so many domestic crushers are in over age operation. The more massive overall tends to aging and the update is just a question of time. 2. Chinese economic develop stable and rapid. Road-building, cement and other infrastructure development will inevitably pull crusher industry growth. 3. Western Development leads a large demand for crusher. According to relevant personage of Chinese construction machinery industry association points out, when an industry or product export growth reaches 40% to 70% is belonged to boom period. After a period of time, it will enter the high risk of trade friction. Our country crushing machine industry is at such a time now. In the current export trade growth situation, we must keep sober and rational and enhance consciousness and means for preventing international trade friction dispute. In international trade, crusher enterprise need attention and prevent include two against two insurance (anti-dumping, anti-subsidy and safeguard measures and special security measures), technical barriers, political and financial and RMB appreciation and so on many kinds of risk. Our country has the overall size of the crusher machinery manufacturing into international production country ranks, but overall competition and development in the future are still cannot rival with the developed countries. The current domestic high-end users and the basic components for products export mainly rely on imports. Therefore, the development of crusher machines in the future should focus on the revitalization of basic technology and infrastructure components to raise the level of independent development.

Extended jaw crusher tooth plate life from design, material selection , assembly and use of the process improvements and other considerations .

Many different types of casting press molding method customarily divided into: ① ordinary sand casting, including wet sand, dry sand and chemical hardening sand three categories. ② special casting, press molding materials can be divided into natural mineral sand and gravel as the main form of special casting material (such as investment casting, cement casting, foundry shell casting, vacuum casting, solid casting, ceramic mold casting etc.) and a metal as the main material of special casting mold (such as a metal casting, pressure casting, continuous casting, low pressure casting, centrifugal casting, etc.) categories. Casting: pressure casting for short, is a way to pressure the molten alloy was poured into indoor, high-speed steel mold cavity filling and make alloy liquid form under pressure castings solidification method. Die casting method different from other main characteristics of high-pressure and high-speed. Casting: Casting, is a special casting. Parts obtained by this method generally do not need to be machined. Such as investment casting, pressure casting. Casting is compared with the traditional casting process in terms of a casting method. It can obtain a relatively accurate casting shapes and high precision. The more common approach is: First, according to product requirements design (can be left margin is very small or no left margin) of the mold with casting wax casting method, get the original wax mold; repeated in the wax mold paint and sanding process, hardened shell and dry; then melt away inside the wax mold is to dewaxing, access cavity; calcined shell to obtain sufficient strength; casting metal material required; clear sand after shelling to obtain accuracy of the finished product. Depending on the product needs or for heat and cold. Wax casting: the lost wax casting method, first appeared in the Spring and Autumn Period, the entire manufacturing process are manual operations. Its process is: the wax into the type of device you want to create the style, after leaching temperature fine slurry to the surface of the wax pattern and sprinkle spinning in the mud surface, repeated many times, so as to form a complete shell, dried heating the wax melt out of the cavity is formed for casting copper solution (ie: copper plus lead, zinc, tin and other metal elements in solution). Completion of casting, after peeled, polished, do the old, an exquisite antique bronze on the show in front of you. Lost wax casting investment casting Precision now known as precision casting, is a little cutting or no cutting precision casting, precision casting industry is an excellent technology, its application is very extensive. It is not only applicable to all types and alloy precision casting, casting and production of dimensional accuracy, surface quality than other methods must be high precision casting, precision casting and even other methods difficult to cast complex, high temperature resistant, not easy to process castings, can be used precision casting investment casting precision casting, too.

Casting structure design should accord with the requirement of machine equipment itself and mechanical processing technic requirements, still should accord with the requirement of casting process, casting structure design should pay attention to the following: 1.easy to make model, core box and moulding : 1) the appearance of the casting should strive to simple, in order to draw, should try to make the casting parting surface flat, and the smallest number; 2) casting lumen need to not use or less use cores when casting , when using core, should be easy to support, fix and exhaust out of the sand, when necessary, should have enough technology hole; 3) for the casting internal and external profile and strengthening rib structure, should be in the same direction with a certain structure of slope; 4) convex parts and casting on the casting body should not differ too much, take the same height, the same distance on the surface of the close several convex sets, best even into the whole convex part. 2.Reduce the tend of casting defects: 1) casting wall thickness should be uniform, in order to prevent the shrinkage, cracking, when need to ensure sequential solidification conditions, should try to make it in one direction change of wall thickness, when need to guarantee the solidification conditions at the same time, should try to make it with the thickness of broken walls; 2) casting wall and wall should be protected from sharp corners and connection between the metal concentration, thick wall and thin wall should be gradually transition, beware of mutation, so as not to cause heat and stress concentration, the formation of hot crack, shrinkage, etc; 3)partial thick section of casting should use hollow out or cast hole structure as far as possible,and appropriately strengthen rib reinforcement ; 4) the hole of casting plane wall, should use convex edge reinforcement in order to reduce the wall thickness; 5) when colling the casting structure ,it should shrink without resistance ; 6) try to avoid a large water level in the casting; 7) waterways, interlining cavity of large area in casting, such as gas path should have some connection column. 3.ensure the casting has good formability, control the minimum wall thickness of casting not less than allowable value.

Generally, many countries' industries, such as electricity, roads, railways and construction industry, can't live without impact crusher. All the industries those are mentioned need a gravel system to produce aggregation to meet the quality requirements. And in this system, the impact crusher has been widely used. By using the impact energy, the impact crusher can break materials which are hard, such as rocks and stones. The materials' size that can be crushed by the impact crusher is less than 500mm, and their compressive strength is not more than 360 MPa. Large crushing ratio, high crushing efficiency and easy maintenance characterizes that. Depending on its characteristics, the impact crusher is widely used in highway construction, hydraulic engineering and architectural gravel processing, and in these industries, it is especially useful to crush granite, limestone, and river gravel. The uses of the impact crusher are related to its structures, and people design the impact crusher to achieve goals. If you are interested in learning the structure characteristics of impact crusher, please read this article on. First, let's talk about the power of the impact crusher. As we can see, the machine has a high chrome plate hammer. When we operate the machine, the hammer will move fast by the power of impact resistance, abrasion resistance and impact strength. And then the materials will be destroyed by the power. Second, the impact crusher is designed with perfect grinding capabilities, high productivity, and high overall efficiency. That means the impact machine can work efficiently and stably. And the machine can crush a lot of materials in the same time. And the machine have compact structure, high rigidity, and huge inertia of the rotor. Unlike the other crushers, the impact crusher has little dust pollution. It has a big feed mouth which makes it can be poured into lots of materials one time. And the impact crusher has a keyless connection, which makes it easily to be cleaned. And in one word, the impact crusher is economical and reliable.

1. Preparation before starting this machine Check whether there is appropriate amount of lubricating oil in the bearing or not; Check all fasteners to see whether they are fastened or not; Check the gap between the screen and the hammer to see whether it is appropriate or not; Rotate the rotor with hand to see whether it is in normal condition, whether rotation direction is correct, whether the hammer impacts against other parts or not. 2. The starting of the crusher Check to make sure the machine and transmission part are in normal condition and then start up the crusher. When unusual circumstance occurs after the starting of the machine, stop it immediately. It is a must to check the machine and eliminate abnormal conditions before re-starting of the machine. 3. Maintenance and use It is allowed to feed materials after the crusher begins its normal operation. It is a must to feed materials evenly and spread materials on the whole working length of the rotor to prevent from load increase of the motor. Check the screen strips regularly, and clean away unwanted materials when screen strips are jammed. Under normal condition, temperature rise of bearing should be within 35?, the maximum temperature should no higher than 70?. If the maximum temperature exceeds 70?, stop the machine immediately, find out causes and eliminate this abnormal circumstance. Stop feeding before stopping the machine. Wait until all materials in the crushing cavity are crushed completely, and then stop the motor. Replace the elastic sleeve on the shaft coupling in time with a new one when it is found damaged. Size of product granules can be adjusted by the following two ways: (1) Change the type of the screen strips, or insert filling blocks in both ends of the screen strip slots to change the gap of the screen strips. (2) Rotate eccentric wheel axle to adjust the gap between the hammer and the screen strips. When the vibration value increases suddenly, stop the machine immediately, find out causes and eliminate this abnormal circumstance. When assemble or replace the hammer, it is a must to keep the balance of the rotor. Total weight of six hammers on one hammer shaft should be equivalent to total weight of hammers on the opposite hammer shaft; weight deviation should be no larger than 100g.

There are adjusting devices (wedge or gasket) between two rolls, with adjusting bolts fixed on the top of wedge. When adjusting bolts hang up wedge, the wedge will drive moving roll away from fixed roll. Roll crusher crushes using compression, with two rolls rotating about a shaft, towards the gap between the rolls. The gap between the rolls is set to the size of product desired, with the realization that the largest feed particle can only be 4 times the gap dimension. The particles are drawn into the gap between the rolls by their rotating motion and a friction angle formed between the rolls and the particle, called the nip angle. The two rolls force the particle between their rotating surface into the ever smaller gap area, and it fractures from the compressive forces presented by the rotating rolls.Some major advantages of roll crushers are they give a very fine product size distribution and they produce very little dust or fines. Rolls crushers are effectively used in minerals crushing where the ores are not too abrasive and they are also used in smaller scale production mining of more abrasive metal ores, such as gold. Coal is probably the largest user of roll crushers, currently, though. Coal plants will use roll crushers, either single roll or double roll, as primary crushers. Usually, these crushers will have teeth or raised forms on the face of the roll. Roll crushers used for minerals and metal ores have smooth faced rolls. It is made of by shell, rotor, grid , blow board, hammer, bracket, lining board etc. The cabinet on the body, by the left side after the cover, and right lateral wall composition, each part of the bolt into an even, the upper opened a charging hopper, internal with high chenban manganese steel, wear can be replaced after, the cabinet and shaft leakage phenomenon between ash is very serious, in order to prevent leakage ash, with shaft seals. The cabinet concrete foundation laid directly, and the anchor bolts fixed. In order to facilitate maintenance, adjust and change article labyrinth, both sides of the body before and after the open a manhole. In order to facilitate maintenance, replacement hammer convenient, two side also symmetrical opened a manhole. The rotor disc by main spindle, and other machines are the stone crushing equipment, and pin shaft and other components, disk drive has six uniform distribution of pin hole, through the pin shaft will 6 8 hammer head hang up. In order to prevent the disc and hammer of the axial channeling move. Pin shaft ends with lock nut fixed. The rotor supported on two rolling bearing. In addition, in order to make the rotor in the motion of storage certain kinetic energy, avoid crushing large materials, the speed of the hammer head too large and reduce the loss from the motor peak load, and in the end of the major axis with a flywheel.

Coal Crusher, as is evident from the name, is a machine that crushes coal. The hard and solid pieces of coal are passed through the Coal Crusher which crushes them in the form of fine powder. The two types of systems that are used for crushing coal can be classified as open-circuit crushing and closed-circuit crushing. The open-circuit crushing system is simple and quick to operate as compared to the closed-circuit crushing system where the crusher is unable to meet the requirement of crushing the coal into specific size. Nevertheless, prior to selecting any of the Coal Crushers, proper research must be done about the available types, in particular, the right type. Crushers types: • Jaw crusher • Roller crusher • Hammer crusher • Ring-Hammer crusher • Impact crusher • Gyratory crusher • Cone crusher • Impact crusher Provided that there are several types of crushers, one must be selective while deciding on any specific one. Below-mentioned are some of the points that must be considered while buying coal crusher: 1. Coal crushers are available in different sizes throughout the market. Make sure that the crusher which matches the original size of the raw coal is selected. Other machines such as Jaw crusher would be required to crush the coal to the desired size if it is larger than the maximum input capacity of the coal crusher. 2. Choose the crusher according to the desired size of the crushed coal. On the whole, Coal crushers come in different crushing capacities such as fine, medium and large crushing. One must select the crusher which can break up the coal into the desired fraction. For example - Jaw crushers would be perfect to crush the coal in less than 13mm. On the contrary, to crush the coal in the grain size of 6mm, Vertical shaft Impact crusher is the ideal choice. 3. Prior to the selection, consider the required amount of crushed coal. For example a hammer crusher is used to get small quantities of crushed coal whereas heavy duty cone crusher can be used for crushing coal in large quantities. 4. Last but not least, choose the crusher according to the water content of the coal. For example- a jaw crusher is suitable to crush the coal containing the moisture content of less than 8% whereas a roller crusher is ideal for crushing coal with water content up to 40%.

For the jaw crusher, the support of the entire machine is running jaw plate and bearing, so in summing up the quality of jaw crusher points on the bottom flat against the rack for processing of mill print available from the following three aspects analysis. First of all talk about the quality of spindle point. Spindle in accordance with the technical specification work force under the relatively poor, it must be forged spindle material. Vehicles directly used for processing of round steel spindle unable to obtain sufficient in quality assurance. This is because after the forged material in the forging process to obtain a higher lattice structure and mechanical behavior. Turning to the direct use of round steel can be greatly reduced production costs, but also greatly reduces the spindle quality. Liming's crusher machine are used forged spindle, spindle through the testing equipment to ensure quality. Therefore, the spindle using forged round bar material is used, there exists an obvious qualitative differences. Again, the wear-resistant parts using a crusher machine key. Jaw crusher wear parts are mainly fixed jaw plate and static jaw plate, jaw plate material is generally manganese steel parts. Manganese steel jaw plates pieces of basic raw materials is a common scrap, scrap the difference is not large, but the key point is the need to add the wear-resistant element. The most important element is the ferromanganese. Quality of manganese steel parts wear resistance strong, and has a certain toughness. The easiest way is to take a test magnet, try, and jaw plate can have a strong magnetic phenomena. If the magnet on the jaw plate has obvious magnetic phenomena, it shows less than the amount of wear-resistant elements to add. In addition, good quality jaw plate after a good heat treatment, the internal grain very refined, so has very good toughness. In the broken hard materials, it will not fracture and so on. The last point is the quality of the bearings, bearing the price of different quality varies greatly. Bearing upon the quality of the actual production can only receive certification. Good bearing is not easy fever, life is very long. The poor quality of the bearing will cause relatively large production losses because of the replacement bearings require professional and tools, while large jaw crusher to replace bearings need a couple of days. Therefore, we must use excellent quality bearings, can ensure the effective long-term crusher run.
