Description

Technical Field

[0001] The invention relates to the technical field of material grinding, in particular to an integrated process device for external circulation coarse grinding and mixer fine grinding. Background Art

[0002] Grinding is the last process in cement manufacturing. The main function of grinding is to grind cement clinker (and retarder, performance adjustment material, etc.) to a suitable particle size, form a certain particle gradation, increase its hydration area, and accelerate the hydration rate to meet the requirements of cement slurry coagulation and hardening. Through grinding, cement particles become smaller and the surface area increases, so that it can react more fully with the chemical substances in the water to generate more hydration products, thereby improving the hardening performance and quality of cement. Therefore, it is necessary to use the integrated process device of external circulation coarse grinding and mixer fine grinding.

[0003] For example, the patent publication number is CN211436342U, which is a cement grinding device for cement production; it includes a crushing chamber, axial holes are provided on both sides of the crushing chamber, a feeding chamber is welded on the lower surface of the crushing chamber, a chute is welded on the lower surface of the feeding chamber, a grinding chamber is provided on one side of the chute, a semi-enclosed feeding port is provided on the side of the grinding chamber close to the chute, and an axial hole is provided on the other side, a feeding port is provided at the bottom of the grinding chamber, a base is welded on the bottom of the grinding chamber, a feeding port is provided on the top of the base, and a transportation channel is provided through the middle of the base. Through the coordinated use of the grinding chamber and the crushing chamber, the cement or raw materials to be ground can meet the production requirements.
