Impact crusher is a new high-efficiency crushing equipment, its features are: small size, simple structure, large crushing ratio, low energy consumption, production capacity, uniform particle size, and selective crushing effect, is promising equipment; crusher hammer biggest drawback is particularly vulnerable to wear and tear and the back plate, especially crushing hard ore, wear is more serious, need frequent replacement. At present, because some wear-resistant materials, and in some metal concentrator has been applied.
Impact crusher is suitable for various kind of coarse, medium and fine materials (granite, limestone, concrete, etc.), due to the plate hammer easy to wear it in hard material crushing applications is restricted, usually used to crushing, crushing or crushing limestone, coal, calcium carbide, quartz, dolomite, curing iron ore, gypsum and chemical feedstock under hard brittle materials.
The main part of the counter attack.
1. Back in.
The role of strike back plate under the impact of material is plate hammer hit, so that the material affected and broken, and broken up by the impact of the material re bounce impact zone, and once again the impact crushing to obtain the desired particle size. Counter plate of the form of a lot, mainly in the form of two types of line and arc. A broken line counter surface can make the material at each point of the counter plate impact in the vertical direction, therefore, the best crushing effect can be obtained. Circular back surface can make material block by the counterattack plate rebound after, at the center of the circle area formed fierce impact crushing zone, with the increasing of material free impact crushing effect.
The counter plate is welded by steel plate. The back surface is provided with a wear-resistant lining board, but also can be used to counter roller or grate lath. A slot counter surface, the product of fine grain content is less, can improve the production capacity of equipment, power consumption. But there are some defects, such as complex structure, difficult to replace, wear, etc.. Most of the rotor of impact crusher is made of monolithic steel, the structure is firm and durable, and easy to install the plate hammer, which can meet the requirements of crushing. The rotor of the small and light impact crusher can also be welded with steel plate.
2.Fang gang
Square is a square, can be divided into welded and seamless. The steel is welded by steel plates welded together, made of square steel tube. Seamless steel is a seamless steel tube to pull and system. The compressive capacity is far greater than the seamed tube. Counterattack broken square up to let the material discharged from the front, back breaking the strict implementation of the heat treatment process, wear-resistant high strength, key components of the Torrington bearings and other countries export Mianjian products, one-time equipment investment and high efficiency. Formula weight: side length of square theory * * 0.00785=kg/m (just as a reference, according to the actual situation).
3. Plate hammer.
The shape of the hammer is closely related to the fastening method and working load. The design of the plate hammer should be satisfied with the requirements of reliable working, loading and unloading, and improving the utilization rate of the metal hammer. Board hammer generally use the high chromium cast iron, high manganese steel and other wear-resistant alloy steel. The shape of the hammer is a lot of, with a long bar, T, S, shape, and the shape of the groove, and so on.
4. Pressing block.
Pressing block is widely used in all kinds of mining machinery, material quality, performance stability, according to different requirements of production. When the load test run is completed, the necessary adjustment to the pressing block is needed. The compression block has the characteristics of chemical composition, heat treatment process, good abrasion resistance and high strength. The clamping mechanism of the clamping block is used for the way of the cylinder drive, connecting rod mechanism and linear guide rail. The whole process uses the pneumatic control, the action is accurate and reliable, and meets the requirements of the use.
