Portland cement processing technology

Abstract

The invention relates to a Portland cement processing technology. The Portland cement processing technology is mainly completed through cooperation of a Portland cement processing machine, the Portland concrete raw material processing machine comprises an outer shell, a crushing mechanism, a material overturning and circulating mechanism, a feeding limiting frame assembly and a cleaning brush assembly, and the Portland cement processing technology specifically comprises the following steps: S1 pouring raw materials; S2, crushing the raw materials; S3, screening the raw materials; and S4, performing circulating operation; and the outer shell is divided into a feeding hopper, a barrel shell and a discharging hopper from top to bottom. The Portland cement is pretreated before feeding, possible cakes are completely and fully crushed, and no treatment omission is generated, so that the quality of concrete after mixing of the Portland cement is ensured.

Description

Technical field [0001] The invention relates to the technical field of building material processing, and specifically proposes a Portland cement processing technology. Background technique [0002] Portland concrete is mainly composed of the cementing material Portland cement, aggregates (sand, stone, etc.), water and admixtures in a certain proportion. Among them, the Portland cement clinker is mainly calcium silicate. , 5% less than 5% limestone or granulated blast furnace slag, and appropriate amount of gypsum ground to make a hydraulic cementitious material, collectively called Portland cement, collectively known as Portland cement in the world. [0003] Portland cement should pay special attention to the problem of moisture-proof during storage and transportation. The strength of cement will be directly affected after being damp, and its strength will gradually decrease as the degree of moisture increases. As the degree of moisture increases, its strength The requirements for...

AI Technical Summary

Problems solved by technology

[0003] During the storage and transportation of Portland cement, special attention should be paid to moisture-proof problems. The strength of cement will be directly affected after being damp, and its strength will gradually decrease with the increase of damp. The requirements for the applicable engineering parts will be gradually reduced. For severely damp cement, it needs to be crushed again to restore its strength, and then mixed into fresh cement for use; cement generally has an expiration date, but even within the expiration date, Due to improper storage and other reasons, some cement may be agglomerated, and the agglomerated cement will inevitably have an adverse effect on the quality of the concrete. Therefore, it is necessary to remove the agglomerated cement that can still meet the requirements for use in certain engineering parts Remove, or directly crush the agglomerates as powder or aggregate and mix them in fresh cement for continued use
