1. Large crushing ratio and low loss
     Using the principle of material layered selection and crushing, the crushing cavity is filled with materials, and the current state-of-the-art hydraulic device can be used to select different pressures according to the hardness of the material, so that the operation of the equipment is 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 double.      2. Long life of wear parts
     After the material is squeezed, sheared and rubbed in the crushing cavity, it will play the role of crushing and self-crushing, so that the wall of the crushing cavity can avoid direct contact, effectively prevent the lining plates from wearing each other, and prevent the material from being polluted by metal pollutants. Therefore, the degree of wearing and wearing parts of the machine is reduced, and the efficiency prolongs the service life of the wear-resistant parts of the equipment.
