Grinding machine and process for preparing concrete additive

Abstract

The invention relates to the field of concrete ingredient preparation, in particular to a grinding machine and process for preparing concrete additive. The grinding machine comprises a base, a right-angle-C-shaped frame, a material receiving mechanism, a screening mechanism, a magnetic separation mechanism and a ball milling mechanism, wherein the right-angle-C-shaped frame is installed on the upper end face of the base, the material receiving mechanism is arranged on the portion, located on the inner side of the right-angle-C-shaped frame, of the upper end face of the base, the screening mechanism and the magnetic separation mechanism are sequentially arranged in the right-angle-C-shaped frame from bottom to top, the screening mechanism is located at the upper end of the material receiving mechanism, and the ball milling mechanism is arranged in the middle of the top end of the right-angle-C-shaped frame. The grinding machine and process for preparing the concrete additive can solve the following problems existing in the process of grinding the steel slag by adopting a dry machining mode in the prior art that the purchase cost and the maintenance cost of machining equipment required when a steel slag machining enterprise makes the steel slag into micro-powder are higher, the occupied field area of the equipment required by steel slag machining is large, the distance between the machines is long, and the machining efficiency of the steel slag is affected by the steel slag conveying process.

Description

technical field [0001] The invention relates to the field of concrete batching preparation, in particular to a grinding and pulverizing processing machine and processing technology for preparing concrete additives. Background technique [0002] Concrete refers to a man-made material made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. The mineral admixture usually includes steel slag particles containing metal, and concrete containing steel slag particles made of metal is usually called steel slag concrete. Therefore, steel slag needs to be processed when preparing mineral admixture ingredients for steel slag concrete. [0003] The process of processing steel slag usually includes crushing, pretreatment, grinding, magnetic separation and screening. Grinding is processed by a ball mill to separate metal-containing st...

AI Technical Summary

Problems solved by technology

[0004] In the prior art, there are usually the following problems in the process of grinding and crushing steel slag by dry processing: 1. Steel slag processing enterprises need to have ball mills, dry magnetic separators and screening machines to be able to dry process steel slag. The above-mentioned machines are bulky and expensive, which increases the purchase cost, maintenance cost and the area occupied by the mechanical equipment when the steel slag processing enterprise prepares and processes the steel slag powder; 2. The distance between the above-mentioned machines is relatively long. Therefore, the process of transporting steel slag affects the efficiency of its processing
