Cement grinding machine won the national invention patent


Cement wet grinding slurry is a kind of high-efficiency fine grinding equipment, which grinds ordinary cement particles from 100μm to about 30μm, and under the action of centrifugal force, the cement slurry is recycled to the mixing tank for stirring and mixing, and then recycled grinding and grinding are carried out again to refine. The invention of cement grinding machine has changed the traditional irrigation slurry technology, overcome the defect of volume shrinkage of ordinary cement paste after coagulation, and improve the mechanical properties of the paste. The preparation and processing stability of wet ultra-fine cement is good, the groutability is significantly improved than ordinary cement, and it has good anti-seepage. Consolidation effect, can achieve similar groutability and chemical slurry, and no pollution. Non-aging. The geometric size of cement particles in the grouting is one of the main factors affecting the ability of cement grouting materials to pour. The fine grinding of grouting cement plays a very good role in improving the groutability and durability of cement paste by reducing the particle size of cement so that it can be poured into the rock mass with finer cracks. The advantage of cement grinding machine is that it is a multi-functional equipment integrating mixing, mixing, grinding, crushing and metering. Under the action of high shear mixing mixer, the cement slurry is fully mixed and reacted with water, then enters the ultra-fine grinding machine for deep refinement and then returns to the high-speed stirring kettle. This technological process fully reflects the complete mixing reaction of cement wet grinding machine, and the shearing, crushing and grinding are getting finer and finer, make the cement slurry to the role of good stability and strong permeability.
