Granulated blast furnace slag powder iron removal device in construction aggregate processor

Abstract

The invention discloses a granulated blast furnace slag powder iron removal device in a construction aggregate processor. The granulated blast furnace slag powder iron removal device comprises a feeding hopper, a blanking pipe and an electromagnetic coil, wherein the blanking pipe is connected with the bottom of the feeding hopper; the bottom of the blanking pipe is connected with a first branch pipe and a second branch pipe at the same time; the first branch pipe and the second branch pipe are symmetric to each other relative to the blanking pipe; a cropping plate I is articulated with the bottom of the blanking pipe through a hinge pin; the cropping plate I is used for sealing the orifice of the first branch pipe or the second branch pipe. The granulated blast furnace slag powder iron removal device has the benefits that magnetic separation can be performed through a second magnetic separation pipe even during maintenance, the whole iron removal device is not required to be stopped,the efficiency cannot be affected, a dispersing hopper and a collecting hopper continuously disperse and collect granulated blast furnace slag powder during the dropping of the granulated blast furnace slag powder, the area in contact with the granulated blast furnace slag powder can be increased, and the iron powder removal effect is enhanced.

Description

technical field [0001] The invention relates to building aggregate processing equipment, in particular to a device for removing iron from granulated blast furnace slag powder in a building aggregate processing machine. Background technique [0002] Slag powder is a new type of green and environmentally friendly product. It can be used as an active mixing material for cement production to achieve energy saving and emission reduction, improve cement performance, and reduce cement production costs. It is also an important admixture for concrete mixing plants. It can directly replace 20-50% cement consumption, to achieve the purpose of reducing heat of hydration, improving workability, and reducing concrete production costs. Due to the characteristics of low heat of hydration, corrosion resistance, strong adhesion to steel bars, high later strength, and anti-micronization, the concrete made of residual oil and slag powder is widely used in industrial and civil buildings, roads a...

AI Technical Summary

Problems solved by technology

[0004] In the existing building aggregate processing machines that use slag powder as raw material, the design of the iron removal device is not reasonable enough, and the iron removal effect is not good. At the same time, the whole machine needs to be shut down frequently for maintenance, which is inefficient
