A kind of cement production method

Abstract

The invention belongs to the technical field of cement manufacture, and in particular relates to a cement production method, comprising the following steps: Step 1, raw material grinding: limestone and clay are crushed and ground and then homogenized. Step 2, clinker calcination: send the homogenized raw meal particles into the preheater and rotary kiln for calcination and slaking; step 3, cement grinding: grind the calcined clinker to a suitable particle size to form a certain Grain gradation; step 4, cement bagging: bagging and sealing the powdered cement after grinding. Wherein, the cement bagging process described in step 4 adopts a kind of cement bagging machine cooperation. When the cement is bagged by the present invention, the sealing effect at the mouth of the bag is improved, and the powdery cement is avoided from overflowing; at the same time, the occurrence of cement powder agglomeration is avoided, the bagging efficiency is improved, and it is possible to ensure The bagging volume is the same.

Description

technical field [0001] The invention belongs to the technical field of cement manufacture, and in particular relates to a cement production method. Background technique [0002] Cement is a powdery hydraulic inorganic gelling material. It can be mixed with water to form a slurry, which can be hardened in air or in water, and can firmly bind sand, stone and other materials together. Because the raw materials need to be crushed into powder during the cement production process, the finished cement is also powdery. The powdery cement is prone to overflow and damp in the air. Therefore, the last step of cement production needs to pack the powdery cement into bags. The cement bagging method that adopts at present is to artificially strut the sack opening of the sealed bag and aim at the discharge opening, and the cement will remove the sack seal after the sealed bag is filled. In the actual production process, this method has the following problems: (1) Complete fit cannot be rea...

AI Technical Summary

Problems solved by technology

[0004] The invention provides a cement production method, aiming at solving the following problems existing in manual bagging of powdered cement at present: (1) the sealing bag mouth and the feeding port cannot be fully bonded, and the After the cement quickly impacts the cement in the sealed bag, the impact force will push the cement in the bag out of the sealed bag opening, causing the cement to overflow, polluting the environment of the production workshop and damaging the health of the operators; (2) the discharge port The cement at the place receives the pressure of the upper layer of cement, which will cause agglomeration to block the discharge port, resulting in a reduction in bagging efficiency; (3) It is impossible to ensure that the bagging amount is the same each time
