Powder cake break-up device of high-pressure paired-roller extrusion mill

Abstract

The invention discloses a powder cake break-up device of a high-pressure paired-roller extrusion mill. The powder cake break-up device comprises a break-up cylinder with an upper opening part and a lower opening part, a break-up wheel arranged in the break-up cylinder and a driving motor arranged outside the a break-up wheel, wherein a powder cake enters the break-up cylinder through the upper opening part and is discharged through the lower opening part after being broken up in the break-up cylinder; the break-up wheel is arranged on the a break-up cylinder through a supporting shaft and consists of a plurality of coaxial break-up blades; the plane in which the break-up blades are positioned is perpendicular to a horizontal plane; the driving motor drives the supporting shaft to rotate. The powder cake break-up device of the high-pressure paired-roller extrusion mill can improve the break-up efficiency and can fully break up the powder cake, so that the subsequent use and further processing of powder are facilitated; furthermore, the fault rate of the powder cake break-up device can be reduced, the abrasion of the break-up device is alleviated, and the service life is prolonged.

Description

technical field [0001] The invention relates to a powder cake breaking device of a high-pressure double-roll extrusion mill, which belongs to the technical field of high-pressure crushing equipment. Background technique [0002] The main working parts of the high-pressure roller press mill are two cylindrical rollers arranged in parallel, and the pressure between the two rollers is usually 50-300 MPa, which can instantly roll the material into a powder cake with a slight external force , the pressed powder becomes a powder. Therefore, the high-pressure counter-roller mill is usually also equipped with a powder cake breaking device to break the rolled powder cake into powder. The powder cake breaking device in the prior art has a simple structure, the breaking efficiency is not high, and the breaking up Insufficient, causing inconvenience to the use and further processing of the follow-up powder; in addition, the existing powder cake breaking device has a high failure rate, ...
