A kind of cement automatic production method

Abstract

The invention discloses an automatic production method of cement. The specific steps of the production method include: mixing and homogenizing crushed limestone, loess and siliceous correction raw materials to obtain cement raw meal, and the cement raw meal is preheated and pre-decomposed. , melting, calcination, cooling, batching, and grinding to obtain finished cement; the cement raw meal is preheated and pre-decomposed into a high-temperature molten pool with a temperature of 1200-1700°C to melt into a molten body; by immersing in the molten body The spray gun sprays fuel and combustion-supporting gas to provide energy, and carries out cement melting and firing reaction to obtain high-temperature molten clinker; the molten clinker is continuously cooled, batched, and ground to obtain finished cement; the specific steps of limestone and loess crushing are as follows: Limestone and loess materials that need to be broken are respectively placed in two feeding barrels of the crushing and mixing device, and the present invention realizes the primary crushing and re-crushing of the limestone and loess used for preparing cement and even mixing after crushing again.

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...

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
