Cement production method

Abstract

The invention belongs to the technical field of cement manufacturing and particularly relates to a cement production method. The method comprises the steps of first, raw material grinding, wherein limestone and clay are homogenized after being broken and ground; second, clinker calcination, wherein homogenized raw material particles are sent into a preheater and a rotary kiln for calcination and curing; third, cement grinding, wherein calcined clinkers are ground to appropriate granularity, and a certain particle grading is formed; and fourth, cement bagging, wherein ground powdery cement is bagged and sealed. In the fourth step, a cement bagging machine is adopted for cooperation in the cement bagging process. When the cement is bagged through the method, the sealing effect at a bag opening is improved, and overflow of the powdery cement is avoided; and meanwhile, the situation of cement powder aggregation is avoided, bagging efficiency is improved, and it can be guaranteed that the bagging amount is identical every time.

Description

Technical field [0001] The invention belongs to the technical field of cement manufacturing, and specifically relates to a cement production method. Background technique [0002] Cement is a kind of powdery hydraulic inorganic cementing material. It becomes a slurry after adding water and stirring. It can harden in the air or in water, and it can firmly bond sand, stone and other materials together. In the cement production process, the raw materials need to be crushed into powder, and the finished cement product is also into powder. The powdered cement is prone to overflow and damp in the air, so the last step of cement production requires bagging of the powdered cement. The currently adopted cement bagging method is to manually open the mouth of the sealed bag to aim at the discharge mouth, and after filling the sealed bag with cement, the mouth of the bag is sealed and removed. In the actual production process, this method has the following problems: (1) The sealing bag mouth...

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
