Ways to Reduce Attrition of Grate of the Hammer Crusher

The hammer crusher generates high-speed rotation with the drive of the motor through the rotor to drive the rotation of the hammerhead fixed on the rotor. Then the hammerhead repeatedly strikes the materials falling down continuously and it gradually crushes the materials with different weight to the required particle size. At last, the grate installed at the discharging port is used for coarse screening of the materials. The finished products which meet the requirements can pass the grate excluding devices, while the materials that do not meet the requirements will enter the secondary crushing process.
In the working process of the Hammer crusher, the attrition of the grate and the supporting frame of the grate are also frequently beside the attrition of the rotor and the hammerhead. Therefore, in order to extend the service life of the equipment, we should improve the attrition degree of the grate and reduce the replacement times. For this situation, the professional manufacturer Henan Hongxing Mining Machinery has put forward the improvement measures for the grate of the hammer crusher after careful study to ensure the normal use and maintenance of the large amount of the users.
The first problem considered is the design of the hammer crusher. We can change the groove cage bar supporting bracket in the equipment design into the design without groove cage bar supporting bracket in the premise that the work performance of the crusher should not be affected. In this way, the discharging length of the materials can be increase effectively. In addition, it can play a good role in terms of the fixity of the grate bars.
Second, we can change the short grate bars into the long grate bars with a convex edge in the middle. At the same time, we can change the small and short curved flat lining installed on both sides of the rack of the bottom of the equipment into a large curved board. The outer arc should be widened. After that, weld the screw holes which are not in use to prevent the scatter of the dust. The improvement of the grate of the hammer crusher can effectively reduce the attrition of the grate, which can save the maintenance costs.
