Technological process

The CKP vertical roller press mill is mainly composed of a motor, a reducer, a grinding disc, a grinding roller, a hydraulic device, a lubrication device, etc. The material enters the center of the grinding disc through the inlet chute. Due to the centrifugal force generated by the rotation of the grinding disc, the material is thrown into the grinding area and compressed and ground by the pressurized grinding roller. The crushed material passes through the outer ring of the grinding disc, falls into the lower shell of the grinding machine, and is scraped into the discharge chute by the scraper plate before being discharged.

Process characteristics

1. The grinding roller adopts a forced lubrication oil supply method to effectively prevent dust from infiltrating the bearing, and adopts a dual sealing mechanism of forced ventilation air seal and skeleton seal
2. The grinding disc liner and roller skin are made of high chromium cast iron, which has a long service life (>30000 hours) and is easy to replace
3. The reducer adopts a static pressure lubrication system, which implements sensor monitoring of thrust bearing oil pressure, oil temperature, etc. to ensure the stability of operation
4. The hydraulic oil station adopts an intermittent and follow-up working mode, equipped with advanced follow-up monitoring components to continuously detect the operating status of the equipment, improve the system operating conditions, and extend the service life of the components
5. Increase production and reduce consumption, with significant results. The use of this equipment for grinding process has enabled the promotion and application of new technologies for extrusion and shear force grinding, resulting in higher grinding efficiency than existing roller presses. It can increase the production capacity of cement raw material grinding by 100%, increase the production capacity of cement clinker by 50%, reduce electricity consumption by 30% -40%, and form a grinding system with a ball mill. The product fineness adjustment range is wide, and the compressive strength of cement is effectively improved.
