Bulk steel slag crushing device

Abstract

According to the bulk steel slag crushing device, bulk steel slag is conveyed to the top of a fixing plate through a feeding opening by means of a conveying device, the steel slag is preliminarily crushed through a mashing assembly, and then the steel slag is pushed to the position between clamping plates through a pushing assembly; a screen is arranged, small particles fall into the crushing barrel through meshes of the screen, large particles continue to be extruded and crushed by the clamping plates until the large particles can pass through the meshes of the screen, and after the small particles fall into an inner cavity of the crushing barrel, the steel slag meeting the requirement can be directly discharged from a discharging opening; steel slag which does not meet the requirement can be accumulated in the inner cavity of the crushing barrel, the steel slag is ground and crushed through the crushing mechanism, particles of the steel slag are further reduced and then discharged through the discharging opening, and the dredging rod is arranged, so that the steel slag can be prevented from blocking the discharging opening.

Description

technical field [0001] The invention relates to the technical field of steel slag crushing devices, more specifically, it relates to a large block steel slag crushing device. Background technique [0002] Steel slag, a by-product of the steelmaking process. It is composed of various oxides formed by the oxidation of impurities such as silicon, manganese, phosphorus, and sulfur in pig iron during the smelting process, and salts formed by the reaction of these oxides with solvents. Steel slag contains a variety of useful components: 2% to 8% of metallic iron, 40% to 60% of calcium oxide, 3% to 10% of magnesium oxide, and 1% to 8% of manganese oxide, so it can be used as raw material for iron and steel metallurgy. The mineral composition of steel slag is mainly tricalcium silicate, followed by dicalcium silicate, RO phase, dicalcium ferrite and free calcium oxide. Steel slag is clinker, which is a heavy melting phase and has a low melting temperature. When re-melted, the liq...

Problems solved by technology

[0003] In the process of crushing steel slag, a crushing device is required. Most of the existing steel slag crushing devices cannot crush large pieces of steel slag, which leads to large limitations and inconvenient use of the device. At the same time, the existing crushing device It occupies a large area, is complex to use, and has a poor crushing effect. Therefore, we propose a large steel slag crushing device
