Smashing and two-stage sorting process and system

Abstract

The invention discloses a smashing and two-stage sorting process which comprises steps as follows: (1), a smashed material is fed into a cascade flow type powder concentrator, a mixture of fine grains and fine powder are sorted; (2), the fine grains and the fine powder are fed into a dust collector with gas of the cascade flow type powder concentrator, and the gas is separated from the fine grains and the fine powder; and (3) the mixture of the fine grains and the fine powder is fed into a fine powder concentrator, and the fine grains and the fine powder are sorted. According to the smashing and two-stage sorting process, the cascade flow type powder concentrator and the fine powder concentrator are adopted in the technological process for separating the fine grains and the fine powder, so that the problems of high power consumption and steel consumption, low yield and high fault rate during production of a prior art are solved. The invention further discloses a smashing and two-stage sorting system.

Description

technical field [0001] The invention relates to the technical field of crushing and sorting technology, more specifically, to a crushing and two-stage sorting process and a crushing and two-stage sorting system. Background technique [0002] In the production of the prior art, when two kinds of products are required in the crushing process, such as fine grain and fine powder; sometimes a stricter grain size range is required, especially for fine grain products, for example, the grain size range of 1mm to 0.1mm is required to be produced products, and requires very little powder less than 0.1mm. In the existing industrial production, generally two screening processes can be adopted, that is, fine particle screening and fine powder screening. The disadvantage of this process is that the screening efficiency of fine particles is very low, and the screening efficiency of fine powder lower. The fine particles mentioned here generally refer to less than a few millimeters, such a...

Problems solved by technology

[0003] Another option in the prior art is to use a screening machine for sorting fine particles, and a powder separator for sorting fine powder. Although this process can solve the problem of fine powder sorting, the screening method for fine particles is still The production efficiency of the whole process is very low

[0004] The use of sieving machines and powder classifiers to sort fine particles and fine powders has the following disadvantages: 1. The screening efficiency for fine particles and fine powders is low, and a large number of qualified particles cannot be separated; 2. The output is very low; 3. Energy consumption and high consumption of wearing parts
