Separation equipment for grinding system of roller press

Abstract

The invention discloses separation equipment for a grinding machine of a roller press with an aim to solve the technical problems about large civil engineering workload, high material conveying height, low equipment dispersion efficiency, high air volume used in the system and high power consumption in system operation when a scatter grading device or a V-shaped powder selecting machine serves as scattering and grading equipment of finished products of the roller press in a semi-finish system of the roller press in the prior art. The technical scheme includes that the separation equipment for the grinding system of the roller press comprises a shell, a powerful scattering portion, an air filtering device, a separation portion and a semi-finished product regulating portion, wherein the shell is used for forming separation working areas, the powerful scattering portion is high in scattering performance and is used for scattering materials fed from a feed inlet; the air filtering device is used for supplying grading force field for the scattered materials, the separation portion is used performing finished-product separation on the materials scattered through the air filtering device, and the semi-finished product regulating portion is used for regulating the amount of the materials to be ground.

Description

technical field [0001] The invention relates to a sorting device, in particular to a sorting device used in a roller press grinding system. Background technique [0002] The roller press is a new type of crushing equipment developed internationally in the mid-1980s. The new extrusion grinding process composed of it has a remarkable effect in energy saving, and is generally valued by the cement industry, and has become a new technology for the development of new grinding processes. [0003] The roller press adopts the principle of high-pressure material layer crushing, and adopts the working method of single particle grouping to achieve the effect of energy saving and production increase. After high-pressure extrusion of brittle materials, the particle size of the materials is greatly reduced. The content of fine powder less than 0.08mm reaches 20-40%, and the content of materials less than 2mm reaches 60-70%. There are a large number of cracks in all economically extruded m...
