subject: Easy Maintenance Of The Impact Crusher [print this page] In the entire system of sand production line, the impact crusher is the third process. After the material is crushed by the jaw crusher, it is crushed by the impact crusher again. Then the material is crushed into the particles of 20 ~ 60mm particles that meet the customers' needs. The impact crusher is a kind of crushing machinery which uses the impact energy. In order to prolong the service life of the impact crusher and ensure that the crusher can continuously run in the production line in the sand, the users should carry out regular maintenance and upkeep for the impact crusher. After the new machine is put into operation, the impact crusher should be comprehensively checked when each shift of work is over.
The impact crusher produced by our company is mining equipment professionally used in breaking ore, which is also called mining impact crusher or stone impact crusher. At present, we launch a new brand of impact crusher: mobile impact crusher. It is more convenient and easier to use than the previous impact crushers, and not confined by topography. The industry calls it movable impact crusher production line.
Hongxing impact crusher is new and high-efficiency ore-breaking equipment. It is a promising equipment with many advantages, such as small volume, simple structure, big reduction ratio(up to 40),low energy consumption, great productive capacity, good finished product shape and selective ore-breaking. However, its biggest disadvantages are its vulnerable board hammer and impact board. Especially when breaking hard ores, they need to be replaced frequently. Owing to the appearance of some wear-resisting materials at present, this series of impact crusher has been used in some concentrating plants.
How to replace the wearing parts of the impact crusher? When you replace the wearing parts of the impact crusher, you should first open shelves. When you begin to use the machine, you should first remove the coupling bolts of the rear rack and the cabinet, and then use the wrench to wrest to the hex head portion of the clamshell device, and then the shelves slowly open. In the meantime, you can use the rack above to hang the rear rack. Repeat the above process and the close the shelves. When the hammer of the impact crusher wears to a certain extent, you should timely adjust or replace it in order to avoid the damage of fasteners and other parts.
When we replace the easily-damaged parts, we should do as follow. First, open shelves and unload the screw connecting upper shelf and middle box, next, use wrench to flip hex head part, and slowly open shelves. At the same time, we can hang the after-frame by cable suspension device, and then repeat the above process until shelves close.
1. Replacement of impact crusher plate hammer: plate hammer should be timely adjusted or replaced when they are worn to a certain extent to avoid the injury of the fasteners and other components.
2. Replacement of impact crusher liner: first, open the cover, remove the cotter pin, slotted nuts and bolts which are used to fix liner, and then replace the liner. If install a new liner, just to upside down the steps.
3. Treatment of impact crusher bearing: the reason why bearing is of over-high temperature are that: (1) excess or deficiency lubricating grease. Then we just try to check whether lubricating grease is excess; (2) smudgy lubricating grease. Then we just try to clean and replace grease;3damaged bearing. Then we just try to replace a new bearing.
Ways to the reduction of hammer crusher head wearing: select a reasonable speed. Quickly improve hammer heads impacting and hardening degree in early process; improve grate bar structure to make the material-excluding expedite; often adjust the gap between parts, so that it is in a proper range. These ways would help reduce hammer wearing. From analyzing factors that influence hammer crusher head, we should adopt different measures to reduce wearing, prolong the service life, reduce material consumption and downtime, reduce costs and improve the economic efficiency of enterprises.
The above methods for prolonging the service life of the impact crusher are provided by the experts in Henan Hongxing Mining Machinery.
