We are all familiar with the hammer head, the consumable part in the hammer crusher, but did you know that the grate bar is also a consumable part in the hammer crusher. In the entire equipment, in addition to the hammer head, the grate bar is the only one that is worn The most serious, and the number of replacements is also relatively high. Therefore, Haoyan Machinery has been studying how to improve the wear resistance of grate bars.
As we all know, it is very easy to see the wear and tear of the grate bars and grate bar support frames of hammer crushers. Therefore, after many studies, Haoyan Machinery found some ways and put forward some improvement suggestions to help users reduce the impact of hammer crushers. The wear and tear of the machine grate bars, I hope it can help us.
The first thing to consider is planning. Without affecting the operation and performance of the crusher, the grooved grate support frame used in the equipment design is changed to a non-groove grate support frame. This can effectively increase the length of material discharge, and at the same time, it can also The fixation of the grate bars plays a very good role and effectively solves the problem in the design of the hammer crusher that the outer edge of the tank with a grooved grate bar support frame cannot support the grate bars after being worn.
Change the short grate bars into long grate bars with a convex edge in the middle. At the same time, improve and melt the small short arc-shaped flat lining plates of each device on both sides of the equipment bottom bracket into a large outer arc widened long arc flat lining. Plate structure and both ends of the long arc lining plate are shortened by 20mm.
The other thing is to drill screw holes with the same drill diameter directly above the screw holes and process them into long annular hole shapes. After doing this, the unused screw holes are welded and sealed. The purpose of welding and sealing is to Prevent the scattering of dust. By improving the grate bars of the hammer crusher, the wear of the grate bars can be effectively reduced, saving a lot of money in repairs and other aspects.
