A raw material screening and processing equipment for refractory brick production

Abstract

The invention relates to the technical field of raw material screening, in particular to a raw material screening treatment equipment for refractory brick production, including a base, a crushing device and a screening device. The upper end of the base is provided with a crushing device on the left side, and the upper end of the base is provided with Screening device. The invention can solve the problem that light grass clippings are often neglected when the raw materials for making refractory bricks are sieved, and light grass clippings are soft and difficult to sieve out, and mixed in raw materials often reduce the quality of refractory bricks; It needs to be crushed before screening, and the traditional crushing method cannot control the volume of the crushed soil, resulting in low applicability of crushing equipment. The screening machine designed by the present invention is especially designed to remove the light grass clippings remaining in the crushed raw material soil block, and at the same time avoids the omission problem that is easy to occur in the traditional crushing method, and can control the volume of the crushed soil block to achieve Improve the applicability of crushing equipment.

Description

technical field [0001] The invention relates to the technical field of raw material screening, in particular to equipment for screening raw materials for making refractory bricks. Background technique [0002] Refractory bricks refer to refractory materials made of refractory clay or other refractory raw materials, which are light yellow or light brown. Refractory bricks are often used as high-temperature building materials and structural materials for construction kilns and various thermal equipment, and can withstand various physical and chemical changes and mechanical effects at high temperatures. According to the different components of refractory bricks, they can be divided into five categories. That is: silicon-aluminum series refractory bricks, alkaline series refractory bricks, carbon-containing refractory bricks, zirconium-containing refractory bricks and heat-insulating refractory bricks. The preparation of refractory bricks usually needs to go through the steps o...

AI Technical Summary

Problems solved by technology

[0003] At present, the following defects usually exist in the screening process of raw materials for making refractory bricks: 1. A large amount of raw material soil clods mined from mines are needed to make refractory bricks, and these clods contain a small amount of metal impurities in addition to The traditional sieving treatment method is usually to screen and remove the metal impurities that are difficult to be broken. Because the light grass clippings are soft and not easy to be sifted out, mixing them in the raw materials often reduces the refractory brick. Quality; 2. The raw soil clods need to be crushed before sieving, while the traditional method is to use crushing rollers for crushing. This method has a better crushing effect when crushing larger clods of soil, but it will miss Partially smaller soil clods reduce the crushing effect, and the volume of the crushed soil clods cannot be controlled, resulting in low applicability of the crushing equipment
