A kind of portland cement preparation technology

Abstract

The invention relates to a Portland cement preparation process, which mainly includes the following steps: equipment inspection, manual feeding, material mixing and material collection. The material set is installed, and the upper end of the material set is provided with a stirring set. The present invention can solve the following problems existing in the stirring process of the existing portland cement slurry: a: the existing portland cement slurry is When placed in the outside world for too long, it will form lumps, and a large amount of lumpy substances will be produced when making clinker, which needs to be broken manually, which greatly increases the workload of employees and wastes manpower; b: After the existing Portland cement slurry is discharged, a large amount of Portland cement slurry will remain on the inner wall of the storage container. If it is not cleaned up in time, it is very easy to condense, resulting in Portland cement slurry Material waste occurs, wasting costs.

Description

technical field [0001] The invention relates to the technical field of Portland cement preparation, in particular to a Portland cement preparation process. Background technique [0002] Portland cement is a hydraulic cementitious material made mainly of calcium silicate, limestone or granulated blast furnace slag below 5%, and an appropriate amount of gypsum. It is collectively called Portland cement in the world. Portland cement has It has the advantages of fast setting and hardening, high early strength and late strength, good frost resistance, good carbonation resistance, dry shrinkage, and good wear resistance, so it is often used in large quantities. In order to meet the needs of use, Portland cement is mass-produced. In the process, the Portland cement raw material is often added with water powder to grind into a slurry, and then poured into a wet kiln to calcinate the clinker. The cement slurry poured into the wet kiln often needs to be stirred to ensure product quali...

AI Technical Summary

Problems solved by technology

[0003] The existing Portland cement slurry often has the following problems when it is stirred: a: When the existing Portland cement slurry is placed in the outside world for a long time, it will often form lumps, so that when the clinker is made A large amount of blocky substances are produced, which requires manual crushing of the blocky substances, which greatly increases the workload of the employees and wastes manpower; b: after the existing Portland cement slurry is discharged, the There is often a large amount of Portland cement slurry remaining on the inner wall of the storage container. If it is not cleaned up in time, it is easy to condense, which will lead to waste of Portland cement slurry and waste costs.
