Automatic production method for cement

Abstract

The invention discloses an automatic production method for cement. The production method specifically comprises the following steps of burdening crushed limestone, loess and a siliceous correction material, homogenizing to obtain cement raw meal, and performing preheating, pre-decomposing, melting, calcining, cooling, burdening and grinding on the cement raw meal to obtain finished cement; meltingthe cement raw meal into a molten mass in a high-temperature molten pool at the temperature of 1,200 to 1,700 DEG C after being pre-heated and pre-decomposed; spraying fuel and a combustion-supporting gas to provide energy through a spraying gun immersed in the molten mass; performing a cement melting and firing reaction to obtain a high-temperature molten clinker; and continuously performing cooling, burdening and grinding on the molten clinker to obtain finished cement, wherein the specific step of crushing the limestone and the loess comprises the process of respectively placing the limestone and the loess in two feeding barrels of a material crushing mixing device. According to the automatic production method for the cement, uniform mixing after primary crushing and secondary mixing of the limestone and the loess for preparing the cement is realized.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to an automatic cement production method. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. Add water and stir to form a slurry, which can be hardened in air or in water, and can firmly bond sand, stone and other materials together. The mixture of early lime and volcanic ash is very similar to modern lime pozzolanic cement. Concrete made of stone not only has high strength after hardening, but also can resist the erosion of fresh water or salt water. For a long time, it has been used as an important cementing material, widely used in civil engineering, water conservancy, national defense and other projects. The production process of cement is representative in cement production. It uses limestone and clay as the main raw materials. , Grind to make raw meal, then feed it into the cement kiln to calcined clinker, and then add appropria...

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a kind of automatic production method of cement, to solve the above-mentioned background technology when realizing the crushing and mixing of limestone and loess, multiple devices need to cooperate simultaneously, and generally only limestone or loess has been carried out for the first time. Crushing, the unevenly broken materials are generally screened out and then put back into the crushing equipment for crushing, thus reducing the problem of work efficiency
