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

The invention relates to a silicate concrete raw material processing machine. The processing machine comprises an outer shell, a crushing mechanism, a material overturning circulating mechanism, a feeding limiting frame assembly and a cleaning brush assembly, the outer shell is divided into a feeding hopper, a barrel shell and a discharging hopper from top to bottom, and the crushing mechanism comprises a matching roller and a crushing roller which are matched with each other; and the material overturning circulating mechanism comprises a cylindrical material screening barrel frame and an arc-shaped material overturning plate. The machine provided by the invention can be used for pre-treating the Portland cement before feeding, and can be used for completely and fully crushing the possiblyexisting agglomerates without causing treatment omission, so that the quality of the concrete mixed with the Portland cement is ensured.
Description
technical field [0001] The invention relates to the technical field of building material processing, and specifically provides a portland concrete raw material processing machine. Background technique [0002] Portland concrete is mainly composed of cementitious material Portland cement, aggregate (sand, stone, etc.), water and admixtures in a certain proportion; among them, Portland cement clinker mainly composed of calcium silicate , less than 5% of limestone or granulated blast furnace slag, a suitable amount of gypsum grinding made of hydraulic cementitious materials, collectively referred to as Portland cement, collectively referred to as Portland cement internationally. [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 engi...
