1. Large crushing ratio and low loss
     Using the principle of selective crushing of materials, the crushing cavity is filled with feed materials, and advanced hydraulic devices are used. Different pressures can be selected according to the hardness of the materials. This makes the equipment operation more stable and reliable, and the mechanical action is more sufficient. The crushing ratio of the equipment is comparable to that of similar equipment. More than doubled.      2. Long life of wear parts
     After being squeezed, sheared and kneaded in the crushing cavity, the materials play the role of crushing and self-crushing, so that the wall of the crushing cavity avoids direct contact, effectively prevents the liners from wearing each other, and avoids the material being contaminated by metal contaminants. Thereby, the degree of vulnerable and consumable parts of the machine is reduced, and the service life of the wear parts of the equipment is effectively prolonged.
