Problems solved by technology

1. When the existing cement production equipment is stirring the clinker, the single-layer mixing blade can only stir the clinker at the bottom, but the upper layer of clinker is not well stirred, which not only needs more time to mix And the quality is also low; 2. The existing cement production equipment can't control the speed of raw material grinding and the temperature of forging box well, and can't adjust according to different raw materials, which not only wastes energy but also has low work efficiency

Abstract

The invention discloses a production process of high fluidity cement, comprising the following steps: a. Crushing and pre-homogenization: in the process of crushing cement production, most of the raw materials need to be crushed, such as limestone, clay, iron ore and coal, etc. ; b. Raw material preparation: After a series of processing, the raw material is made into a certain fineness; c. Preheating decomposition; d. Clinker calcination: Calcining the raw material in the forging box until it is partially melted; e. Cement grinding: Add some mixed materials or admixtures in step d into the mixing box, grind and mix evenly to form cement; d. Cement packaging. In the production process of a kind of high-fluidity cement described in the present invention, the clinker is fully stirred by the two stirring bodies at the lower end of the rotating column, which improves the quality of the product, and the raw material grinding speed and the temperature of the forging box are adjusted by the control device to improve the quality of the clinker. work efficiency.

Description

technical field [0001] The invention relates to the technical field of cement production, in particular to a production process of high fluidity cement. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry. It can be hardened in the air or in water, and can firmly bond sand, stone and other materials together. Therefore, cement is an important glue. Concrete materials are indispensable in civil construction, water conservancy, national defense and other projects. 1. When the existing cement production equipment is stirring the clinker, the single-layer mixing blade can only stir the clinker at the bottom, but the upper layer of clinker is not well stirred, which not only needs more time to mix And the quality is also low; 2, the existing cement production equipment can not control the speed of raw material grinding and the temperature of forging box well, can not adjust according to different raw...
