Efficient scattering-grading equipment with multi-stage scattering mechanism for cement processing

Abstract

The invention discloses efficient scattering-grading equipment with a multi-stage scattering mechanism for cement processing. The efficient scattering-grading equipment comprises a scattering bin and a grading bin, wherein the scattering bin is arranged at the upper end of the grading bin; a scattering main shaft is arranged in the scattering bin; at least one triangular reverse beating mechanism is arranged on the inner wall of the scattering bin; the lower end of the scattering main shaft extends into the grading bin; a centrifugal disc and a scattering disc are sequentially arranged on the scattering main shaft from top to bottom; a coarse material bin is further arranged in the grading bin in a sleeving manner; a transition bin is arranged between the coarse material bin and the scattering bin; a two-stage secondary scattering mechanism is arranged in the transition bin; a bidirectional air-blasting flow guide device is arranged on the coarse material bin; a secondary beating plate is further arranged at the inlet of the coarse material bin; and a pre-crushing device is further arranged at the charge port of the scattering bin. The scattering-grading equipment is reasonable in structural design; the structural manner of air separation is changed, and the mode of bidirectionally simultaneous air separation is adopted, so that the matching degree of the air separation and scattering is increased; and the pre-crushing device is added, so that the crushing efficiency is increased, the crushing effect is improved, the scattering is more comprehensive and thorough, and the collection amount of a cement powder can be greatly increased.

Description

technical field [0001] The invention relates to a high-efficiency breaking and grading equipment for cement processing with a multi-stage breaking mechanism. Background technique [0002] The dispersing and grading equipment is to disperse the cement blocks that have been rolled into a cake shape to disperse the powdery cement powder. The existing dispersing and grading equipment still has some defects in the process of use: one is the cake Shaped cement blocks directly enter the dispersing bin to disperse, which has a large area, is not easy to disperse, and is easy to damage the internal parts in the dispersing bin, resulting in the phenomenon of frequent replacement of parts, and the efficiency of such dispersing is not enough. The cement powder collected each time is not enough, and the powder collection speed is slow. [0003] The existing winnowing structure needs to be improved, because the existing winnowing cannot match the speed of breaking up, resulting in a low ...

[0002] The dispersing and grading equipment is to disperse the cement blocks that have been rolled into a cake shape to disperse the powdery cement powder. The existing dispersing and grading equipment still has some defects in the process of use: one is the cake Shaped cement blocks directly enter the dispersing bin to disperse, which has a large area, is not easy to disperse, and is easy to damage the internal parts in the dispersing bin, resulting in the phenomenon of frequent replacement of parts, and the efficiency of such dispersing is not enough. The cement powder collected each time is not enough, and the speed of collecting powder is slow

[0003] The existing winnowing structure needs to be improved, because the existing winnowing cannot match the speed of breaking up, resulting in a low degree of cooperation between winnowing and breaking up, so that some cement powder will be crushed together with the coarse material before winnowing. In addition, the existing dispersing strength is not enough, and the dispersing is not comprehensive enough, resulting in the need for multiple cycles of dispersing to finally achieve the collection of cement powder
