Recycling processing treatment system for steelmaking processing waste steel slag

Abstract

The invention relates to a recycling processing treatment system for steelmaking processing waste steel slag. The system comprises a shell, a flow guide frame, supporting plates, a first crushing mechanism, a shaking mechanism and a second crushing mechanism, wherein the shell is of a concentric-square-shaped structure with openings in the upper end and the lower end, the flow guide frame is installed at the upper end of the shell, the supporting plates are symmetrically installed on the left side and the right side of the lower end of the shell, and the first crushing mechanism, the shaking mechanism and the second crushing mechanism are sequentially arranged in the shell from top to bottom. With the system, the following problems existing when an existing large jaw crusher is used for carrying out jaw crushing on the steel slag can be solved: after the steel slag is subjected to jaw crushing of a primary degree, a finer jaw crusher needs to be used for carrying out secondary jaw crushing on the steel slag, and consequently, the jaw crushing efficiency of the steel slag is low; the steel slag is easily adhered to the surfaces of jaw crushing columns, so that the jaw crushing columns are easily stuck by the adhered steel slag, and then the jaw crusher is frequently maintained; and the jaw crushing effect of the existing machine is poor, so that ball-milling time of the steel slag after jaw crushing needs to be prolonged.

Description

technical field [0001] The invention relates to the field of steel slag recovery and reuse, in particular to a processing system for steel slag recovery and reuse of steelmaking processing waste. Background technique [0002] Steel is an essential and important material for national construction and the realization of the four modernizations. It has a variety of varieties and is widely used. However, steel slag will be produced in the process of steelmaking. The process of processing steel slag commonly used in the prior art is: first jaw crushing, then ball milling, and then Vibration screening is performed again. After screening, the larger particles are separated by air, and the smaller particles are then subjected to magnetic separation. Jaw breaking is the first process for processing steel slag; [0003] At present, large-scale jaw crushers are usually used to crush steel slag in the market. However, there are usually the following problems when using large-scale jaw c...

Problems solved by technology

[0004] 1. Since the existing large-scale jaw crusher can only crush steel slag to one level at a time, after the steel slag has been crushed to a primary level, it is necessary to replace the finer jaw crusher to perform secondary jaw crushing on steel slag , leading to low efficiency of jaw breaking of steel slag, and wasting electricity and oil resources required for the operation of jaw breaking machinery;

[0005] 2. When the jaw brea
