CKP vertical pre-grinding mill
Description:
CKP type roller mill is through three symmetrically rotating rollers under high pressure, with the rotation of grinding disc to shear, squeeze and grind the material on the grinding disc. Its unique roller shape design and material layer grinding technology greatly reduce the unit energy consumption, and is widely used in the material grinding process of construction materials, metallurgy, chemical industry and other industries. It can be combined with the existing ball mill to form circulating pre-grinding, circulating grading pre-grinding, and final grinding system. The power consumption of comprehensive grinding is reduced by 30% -40%, and the output is

Introduction
CKP type roller mill is through three symmetrically rotating rollers under high pressure, with the rotation of grinding disc to shear, squeeze and grind the material on the grinding disc. Its unique roller shape design and material layer grinding technology greatly reduce the unit energy consumption, and is widely used in the material grinding process of construction materials, metallurgy, chemical industry and other industries. It can be combined with the existing ball mill to form circulating pre-grinding, circulating grading pre-grinding, and final grinding system. The power consumption of comprehensive grinding is reduced by 30% -40%, and the output is increased by 50% -100%, achieving the goals of energy saving and emission reduction and high-efficiency grinding with high output and low consumption. It has high economic and social benefits.Process flow
CKP type Vertical roller grinding mill is mainly composed of motor, reducer, grinding disc, grinding roller, hydraulic device, lubrication device, etc. The material enters the center of grinding disc through the inlet slide. Due to the centrifugal force generated by the rotation of grinding disc, the material is thrown into grinding area, and the material is pressed and ground by the pressurized grinding roller. The crushed material passes through the outer ring of grinding disc, falls into the lower shell of the mill, and is scraped into cutting slide by the scraping plate and discharged.Process characteristics
1. The grinding roller adopts forced lubrication to effectively prevent dust from infiltrating into the bearing, and adopts a double sealing mechanism of air seal and skeleton seal with forced ventilation.2. The grinding disc liner plate and roller skin of the grinding disc are made of high chromium cast iron, which has a long service life (> 30000Hr) and is easy to replace.
3. The reducer adopts static pressure lubrication system to implement sensor monitoring of oil pressure of thrust bearing bush and oil temperature to ensure the stability of operation.
4. The hydraulic oil station adopts intermittent and follow-up working mode, and sets advanced follow-up monitoring components to carry out uninterrupted and continuous detection of the operating state of the equipment, which improves the operating condition of the system and extends the life of components.
5. Increase production and reduce consumption, the effect is remarkable. The use of this equipment grinding technology has achieved the popularization and application of extrusion and shear force grinding new technology, which has higher grinding effect than the existing roller press. It can increase the production capacity of cement raw material grinding by 100%, increase the production capacity of cement clinker by 50%, reduce the power consumption by 30% to 40%, and form grinding system with ball mill, the product fineness adjustment range is wide, and the cement compressive strength is effectively improved.
