Revolving cracking machine

Abstract

A circulating rubbing crusher belongs to the field of crushing equipment. The crusher includes a driving axle arranged on the frame, a rotating grinding wheel head coupled with the driving axle and afixing frid fixed at the frame, the crusher is characterized in that a variable working clearance with a bigger upper part and a smaller lower part is formed between the rotating part and the fixing part by setting different working diameters of the rotating part and the fixing part, crushing bulges are arranged at the working surface between the rotating part and the fixing part, and the massivematerial to be crushed is one-time crushed to the granular material with the necessary dimension using the working mode of rubbing crushing with the relative movement of the crushing bulges arranged between the rotating part and fixing part. The particle size of the discharging material is adjustable and can automatically adapt the different massive material to be crushed, the crusher has the advantages of a larger proportion range of the particle size of the feeding / discharging material, guaranteeing the working accuracy of the material with a smaller particle size and further increasing theoperating efficiency of the crushing work. The crusher can be widely used in the crushing field of various materials.

Description

technical field [0001] The invention belongs to the field of crushing equipment, in particular to a crusher for crushing bulk materials into required granular materials at one time. Background technique [0002] Crusher is a mechanical device that can crush bulk materials into granular materials. It is widely used in mining, cement, refractory materials, ceramics, abrasives, coal, building materials, and metallurgy industries. [0003] The existing ordinary crushing granule machine usually consists of an impact grinding head and an outer lining plate to form a crushing cavity. A drive shaft connected to a driving device (motor) drives the grinding head to rotate. The relative movement between the plates, the material is impacted by the grinding head, and through the action of impact / extrusion, the large material to be crushed that enters from the upper part of the crushing chamber is broken into granular materials, which are discharged from the lower part of the crushing cha...

Problems solved by technology

[0007] In the actual use process, it is found that the above-mentioned improved technical solutions still have certain deficiencies, and the adaptability to bulky materials, the processing accuracy of smaller particle size materials, and the crushing work efficiency still need to be improved.
