In recent years, with the increasing demand for aggregates for sand and gravel, the use of impact crushers has become more widespread. This equipment is commonly used in cement production lines, sand aggregate production lines, construction waste brick production lines, and other fields. The consumption of impact hammers, counterattack boards and other parts of the impact crusher also increases.
The impact crusher is a new type of high-efficiency crushing equipment, which is characterized by small size, simple structure, large crushing ratio (up to 40), low energy consumption, large production capacity, uniform product size, and selective The role of broken ore is a very promising device. However, its biggest drawback is that the hammers and counterattack boards are particularly vulnerable to wear. In particular, the hard ore is broken, and the wear is even more severe and needs frequent replacement. At present, due to the appearance of some wear-resistant materials, it has been applied in some metal concentrators.
Choosing high-efficiency, low-energy impact crushers can often achieve a multiplier effect in the production process, which can minimize production costs, provide production efficiency, and create profitability under the protection of efficiency and quality. Impact crusher equipment. Impact crusher is a crushing equipment with a long history. Comparing with the traditional hammer crusher, the two work principles are similar. They all crush material crusher by impact method, but the structure and working process are different. The main difference is that: the hammer of the impact crusher is the material that meets the input from the bottom up, and throws it to the counterattack board above the Austrian, and the hammerhead of the hammer crusher hits the material along the direction of the falling of the material. In order to ensure the continuous operation of the impact crusher in the sand production line and continue the service life of the equipment, the user should perform regular maintenance and maintenance. After the new aircraft is put into operation, it is necessary to conduct a comprehensive inspection of counterattacks when each shift is completed. After a week of operation, conduct a thorough inspection of the counter-fighted motor and lubrication. The contents of the inspection include tightening of the fixed parts, belt drive, bearing seals, counter linings, and wear of the lining plate for full-position inspection, and a regular maintenance and replacement system in conjunction with the inspection cycle. The advantages of the impact crusher design and its superior performance are the fundamental reason for the gradual market. Now we talk about the impact of the design of its board hammer on production efficiency:
1. The impact hammer design of the impact crusher is also an important reason for the impact crusher. The back of the hammer is symmetrically designed with the same size of countersinks and gills for easy assembly. The outer surface of the impact hammer of the impact crusher should be designed as a plane, and it is relatively easy to match and fix the hammer on the rotor body. The thickness of the hammer should be increased to 120mm. In order to reduce the weight, the weight of the hammer is kept the same as that of the original plate. In the other two surfaces of the hammer, the groove is symmetrically designed as a groove, which can also be used as a wear boundary. In order to increase the stability of the impact crusher bolt work, so that it does not allow bending and shearing, designed with the countersink matching core.
2. When improving the structural hammer structure of the impact crusher, the surface of the hammer structure is designed as a planar structure, so that the hammer can be more easily matched with the boring head on the rotor. Simultaneously, it is designed symmetrically on the back of the hammer. The same size of countersinks and fistulas, and to maintain the consistency of the width of the countersink and the width of the fistula, improve the fastening of the plate hammer and the rotor structure. It can greatly extend the life cycle of the impact crusher plate hammer, extend the service life of the equipment and improve the production efficiency of the impact crusher.
