Circulating slag crushing and iron separation device

Abstract

The invention discloses a circulating slag crushing and iron separation device. The circulating slag crushing and iron separation device comprises a base, wherein a crushing box is fixedly arranged on the base through a support plate, a circulating box is fixedly arranged at the top of the crushing box, a sieve screen is arranged slantwise at the bottom in the crushing box, an unloading groove is connected to the left side of the sieve screen, a receiving box is further arranged on the support plate at the left side, a screw elevator is arranged at the upper left side of the receiving box, and a discharge port in the top of the screw elevator is connected to the left side in the circulating box through a circulating pipe; and an unloading pipe is connected to the bottom of the crushing box, a fixed shaft is further fixedly connected to the bottom of the crushing box through a support, a rotary barrel is rotationally connected to the fixed shaft, a cylindrical magnet is further fixedly installed on the fixed shaft, and the cylindrical magnet is located in the rotary barrel. According to the circulating slag crushing and iron separation device disclosed by the invention, the crushed slag is filtered through the arrangement of the sieve screen, and circulating crushing is carried out on the incompletely-crushed ores by the screw elevator, so that the crushing quality for all the slag is ensured; and iron powder is received and reutilized through the arrangement of the rotary barrel and the cylindrical magnet.

Description

technical field [0001] The invention relates to the field of ore processing machinery, in particular to a circulating slag crushing and iron separation device. Background technique [0002] Slag is the waste residue produced when iron and steel plants smelt pig iron. Slag can be crushed to form slag powder. Slag powder is a new type of green and environmentally friendly product. It can be used as an active mixing material in cement production to achieve energy saving and emission reduction, improve cement performance, and reduce cement production costs. It is also an important component of concrete mixing plants. The admixture can directly replace 20-50% of the cement consumption of the second crushing roller, so as to reduce the heat of hydration, improve the workability and reduce the production cost of concrete. Due to the characteristics of low heat of hydration, corrosion resistance, strong adhesion to steel bars, high later strength, and anti-micronization, the concre...

AI Technical Summary

Problems solved by technology

Existing residual iron removal generally uses the characteristic that the specific gravity of residual iron is greater than that of slag to carry out residual iron sorting. The treatment process is complicated, consumes manpower and material resources, and the work efficiency is not high. There are also some devices that do not directly recycle residual iron, so that will cause waste of resources
