Tailing slag aerated concrete block manufacturing method

Abstract

The invention provides a tailing slag aerated concrete block manufacturing method which adopts following equipment for manufacturing aerated concrete blocks. The equipment comprises a base, a discharging device and a crushing device, the lower end of the base is connected with the existing ground, and the discharging device is arranged above the base. The crushing device is arranged at the lower end of the discharging device. The discharging device adopted in the method can control the feeding amount of tailing slag raw materials by controlling the opening and closing degree of two opening and closing plates, and the situation that the subsequent crushing effect on the tailing slag raw materials is affected due to the fact that excessive tailing slag raw materials are fed at a time can be avoided; and the adopted crushing device can timely remove the tailing slag adhering to the surface of a crushing roller in the crushing process, so that the situation that the subsequent crushing function is influenced due to the fact that the tailing slag adhering to the surface of the crushing roller is relatively thick is avoided.

Description

technical field [0001] The invention relates to the field of aerated concrete blocks, in particular to a method for manufacturing tailings slag aerated concrete blocks. Background technique [0002] Air-entrained concrete block is a new type of building material that is lightweight, porous, thermally insulated, good in fire resistance, nailable, sawable, planable, and has a certain degree of earthquake resistance. Air-entrained concrete block is suitable for filling walls in high-rise buildings The main raw materials for making aerated concrete blocks are sand, fly ash, lime, cement and granular blast furnace slag, etc. The tailings slag belongs to the granular blast furnace slag. Some of the residual gangue and ore left after parting contain ferrous metals or rare metals. Therefore, when making tailings slag aerated concrete blocks, it is necessary to crush the larger tailings slag raw materials to obtain smaller particles. The tailings slag that meets the requirements is ...

AI Technical Summary

Problems solved by technology

[0003] 1. Most of the existing equipment adopts one-time feeding method when feeding tailings slag raw materials. One-time feeding will easily lead to low crushing degree of tailings slag. At the same time, during the crushing process, the crushing degree cannot be adjusted and controlled. The tailings slag with many particle sizes and specifications is obtained, which makes the practical value of the equipment not high;

[0004] 2. In the process of crushing the tailings slag, most of the existing equipment cannot timely remove the tailings slag debris adhering to the crushing device, and the surface of the crushing roller is easy to accumulate thicker tailings slag debris. As a result, the crushing roller cannot perform the crushing function well in the subsequent crushing process, which affects the crushing effect on the tailings slag.
