The common counterattack is usually equipped with 4 hammer, so in order to improve production efficiency, why not add two hammer?
There are 3 main factors that manufacturers consider in the design: 1) size of discharge; 2) output; 3) cost (production cost for equipment manufacturers and maintenance and replacement cost for users). As we know, after the material enters the impact crusher, it is repeatedly crushed between the plate hammer and impact plate, so the wear of these two parts is more serious. If the number of plate hammer is higher, the production cost will increase for both equipment manufacturers and users. On the other hand, if the number increases, the material is crushed between the plate hammer and the impact plate more times, resulting in a finer material size and lower output. In order to keep the overall production balance, the number of plate hammers is not the better.
