Novel scattering classifier

Abstract

The novel scattering and grading machine comprises a machine body, a through scattering assembly is arranged at the top of the machine body, a primary screening cavity is formed in the position, below the scattering assembly, in the machine body, a multi-stage screening cavity is formed in the position, below the primary screening cavity, in the machine body, and a through discharging opening is formed in the bottom of the machine body. Materials can be subjected to primary screening, large-particle materials are screened to a dispersing disc, damage to parts for working below is reduced, the situation that the materials are stacked to block meshes of a first filter screen can be avoided, the materials can be screened into three grades according to the particle size, and the screened materials of the three grades are discharged and collected separately; according to the device, materials with different particles can be conveniently and secondarily scattered to different degrees subsequently, material waste caused by excessive scattering is avoided, large particles obtained after primary screening are ground into small particles, material accumulation after screening is avoided, and the overall working efficiency of the device can be improved.

Description

technical field [0001] The invention relates to the technical field of cement processing, in particular to a novel dispersing and classifying machine. Background technique [0002] Cement is a powdery hydraulic inorganic cementitious material that will solidify and harden after being mixed with water. It is usually not used alone, but is used to combine with sand and gravel (aggregate) to form mortar or concrete. The main raw material of cement is lime or calcium silicate, which can resist the erosion of fresh water or salt water after hardening. As an important cementing material, it is widely used in civil engineering, water conservancy, national defense and other projects. Breaking and grading equipment is a device that breaks up the cement block that has been rolled into a cake shape, and disperses the powdered cement powder. The breaking and classifying machine is a new type of material cake breaking and sorting equipment developed in the early 1990s. It integrates mat...

AI Technical Summary

Problems solved by technology

[0003] At present, the screening efficiency of cement dispersing and classifying machines for fine powder is low, and fine powder is easily discharged together with coarse powder, which affects production efficiency
