Technical Field

[0001] The utility model relates to the technical field of double-stage pulverizers, in particular to a double-stage pulverizer with a dustproof structure. Background Art

[0002] The double-stage pulverizer achieves double crushing of materials through its unique design and function, thereby improving the crushing efficiency and uniformity. This pulverizer has the following significant features: Double rotor upper and lower stage crushing: The pulverizer uses two sets of rotors in series, so that the material crushed by the upper rotor is immediately crushed again by the hammer of the rapidly rotating lower rotor. The materials in the inner cavity collide with each other at high speed and crush each other, achieving the effect of hammer powder and material powder, and directly unloading; No screen grate bottom, suitable for high-humidity materials: The design of the double-stage pulverizer has no screen grate bottom, and there is no strict requirement for the moisture content of the material. There is no problem of clogging the screen plate, and there is no problem of fine powder not being able to be discharged in time and repeated crushing. Therefore, the crushing efficiency is high and there is no ineffective wear of the hammer head.
