Advantages:

(1) The gap between counter board and the board hammer can be easily adjusted, control the particle size effectively, particle shape is good;

(2) ore crushing along the joint surface, so less power consumption, high efficiency;

(3) keyless access and easy maintenance, economical and reliable;

(4) full-featured crushing, high productivity, small mechanical wear, high comprehensive benefits;

(5) high chrome plate hammer, impact resistance, abrasion resistance, large impact force;

(6) simple structure, small size, light weight, large capacity, low production costs. Large feeding hole, high crushing chamber, adapt to high hardness material;

(7) large ratio of crushing, up to 40, it is possible to simplify the crushing process, can make three sections break into two or one break, lower concentrator equipment cost
