vertical shaft impact crusher
Features of Vertical Impact Crusher
1. Vertical impact crusher is a new type of medium and fine stone crushing equipment developed in the 1990s. It is also a model widely used in the world to replace cone crushers, roller mills, and ball mills.
2. Novel and unique structure, stable operation, simple structure, convenient operation and maintenance, easy installation, and low cost.
3. Low energy consumption, high output, large crushing ratio, fine crushing and coarse grinding functions.
4. The equipment is small in size, easy to operate, easy to install and maintain. High efficiency and energy saving, high crushing efficiency. The processing capacity is large, and the output is 50-500 tons/hour. Compared with the sand making equipment under the same power, the output is increased by 35%. And the performance is relatively stable.
5. It has the function of shaping, the product is cubic, the bulk density is large, the ability to pass non-crushed materials is strong, and it is less affected by the moisture of the material. The water content can reach 8%. The finished product has a good grain shape and a hexagonal polyprism. Reasonable, special use and machine-made sand and stone shaping. Many customers have proved that the comprehensive effect of sand making and shaping is 30% higher than that of other equipment of the same power.
6. During the production process, the stone can form a protective bottom layer, the machine body is wear-free, durable, and can crush medium-hard and extra-hard materials (such as corundum, sintered bauxite, etc.).
7. A small number of wearable parts are made of super hard wear-resistant materials, small in size, light in weight, easy to replace parts, the product is cubic, iron pollution is small, wearing parts consumption is low, the most ideal impact crushing, impact angle, the most reasonable The impact speed design of the material and the friction of the wear-resistant parts are less, and the operating cost is 30% lower than that of the traditional equipment, which directly reduces the use cost of the impact crusher and greatly improves the profit margin of the machine.
8. Light weight, various installation methods, movable installation, etc.
Failure maintenance of vertical impact crusher
Due to the relatively bad working conditions of the vertical impact crusher, the torque or vibration it bears during operation is large, which often causes the transmission system to fail. The common ones are the bearing chamber, bearing position wear, shaft head, keyway wear, belt pulley, coupling Wear of the inner hole of the shaft device, etc. At the same time, due to severe dust on the production site and poor lubrication conditions, the wear of the transmission parts will also be accelerated.
In addition, modern production enterprises have a high degree of automation and continuity, and the requirements for smooth operation of equipment are also increasing. The crushing equipment is also developing in the direction of large-scale and high-volume production. The difficulty of disassembly, transportation and maintenance is also increasing. If there is no advanced maintenance method, the above equipment problems cannot be solved quickly and effectively in the first time. Seriously affect the production of enterprises.
Solution to the bearing bit wear of the vertical impact crusher: Vertical impact crusher bearing bit wear
During the operation of the vertical impact crusher, due to various factors, the bearing position causes abrasion. After the problem occurs, it must be repaired by welding or brushing and machining after the traditional method. However, the thermal stress caused by the high temperature of repair welding cannot be completely eliminated, and short shafts are prone to occur during operation, causing major accidents; brush plating is easily peeled off due to the thickness of the coating; and the above methods are all repairing metals with metal, which cannot be changed. The "hard-to-hard" coordination relationship will still cause wear again under the combined action of various forces.
