Crusher for crushing carbon blocks

Abstract

The invention discloses a crusher for crushing carbon lumps. The crusher comprises a shell, a first crushing roller, a first driving device, a second crushing roller and a second driving device, wherein the first and second crushing rollers are oppositely arranged in a feed inlet of a shell, and a plurality of first circular shearing and rolling edges are arranged on the outer surface of the first crushing roller along the circumference of the first crushing roller or first shearing and rolling edges which are spirally arranged on the outer surface of the first crushing roller; a plurality of second circular shearing and rolling edges are arranged on the outer surface of the second crushing roller along the circumference of the second crushing roller or second shearing and rolling edges which are spirally arranged on the outer surface of the second crushing roller; the first and second shearing and rolling edges are arranged in a staggered manner and are close to each other; a gap is reserved between the first and second shearing and rolling edges and the gap between the first and second shearing and rolling edges is adjustable in width. The purpose of precisely controlling the granularity and graduation of crushed carbon powder is achieved.

Description

technical field [0001] The invention relates to the field of crushing carbon materials, in particular to a crusher for crushing carbon blocks. Background technique [0002] Carbon powder is the main solid raw material of electric carbon products. To manufacture any electric carbon products, the first process needs to make carbon raw materials into powder. Its various properties determine the main characteristics, scope of use and application value of the product. [0003] The performance of carbon powder can be characterized by chemical composition, physical properties and process. Its chemical composition is mainly carbon and other impurity elements; its physical properties are particle size, particle shape, particle size distribution, true density and specific surface area, etc.; its process aspects are bulk specific gravity, fluidity and compressibility, etc. . Powders with the same chemical composition can obtain products with different properties due to their differen...

AI Technical Summary

Problems solved by technology

[0005] The invention provides a crusher for crushing carbon blocks to solve the problem that there is no special crusher for crushing carbon raw materials to form carbon powder; the particle size and gradation of the crushed carbon powder cannot be accurately controlled, so that Carbon powder is in the stage of passive use and development, and the technical problems of economic and technical losses caused by the inability to give full play to the maximum function and performance of carbon materials
