Working Principle
High pressure roller mill is an efficient crushing equipment based on the principle of "aggregate crushing", which implements quasi-static crushing of the material layer (or bed). It uses the principle of laminated crushing to produce a large number of micro cracks, collapses, and sparse particles on the surface and inside of the material during the extrusion process
Loosening can significantly reduce the Bond work index of roller grinding products and improve the grindability of materials.
Two motors drive two grinding rollers to rotate towards each other through a reducer, and the materials in the pipeline and silo are pulled into the gap between the rollers under the action of gravity and friction between the materials. The hydraulic system applies pressure to the rollers and the materials between them through oil cylinders, bearing seats, and bearings, enabling the materials to be crushed. The crushed material is sent to the grading equipment through the conveying equipment. After grading, the material with a certain particle size is sent to the subsequent section, and the coarse particles are returned to the high-pressure roller mill for re squeezing.
Product Advantages
The current popular old-fashioned high-pressure roller mills in the market inevitably cause roll deviation during use due to the integral design of the dynamic roller bearing seat, resulting in uneven roller gap sizes and uneven force distribution on the material cake. The pressure is low in areas with larger roller gaps, resulting in poor performance. The pressure is too high in areas with smaller roller gaps, causing excessive wear on the roller surface. The problem of roller deviation greatly affects the performance and service life of the roller press.
The new frame structure of the new high-pressure roller mill connects two bearing seats on the same main shaft of the moving and fixed rollers into a whole. The bearing seats are both split bearing seats, and the frame is designed in an arch shape. The bearing seat and the frame are welded together. The two bodies are connected by two pull cylinders, and the oil cylinder is connected to the frame through a shaft pin. The frame and the base are also connected through a shaft pin. The fixed roller frame is fixed by two shaft pins, one is the load-bearing shaft pin and the other is the positioning shaft pin. Its structural form increases the torque of the oil cylinder, allowing for the same squeezing effect to be achieved with less pressure. The feeding port bracket is connected to the base, effectively reducing the footprint and eliminating the phenomenon of roller deviation in traditional roller presses.
The integrity of the new frame of the new high-pressure roller mill is improved by eliminating the deviation of the moving roller axis, allowing the fixed roller surface to be equipped with large-diameter side flanges to wrap the moving roller into a closed feeding space. The material will not escape from the side, greatly reducing the edge effect of the high-pressure roller mill and making the use of the high-pressure roller mill more significant. The fine particle content of the obtained product is increased. At the same time, due to the joint rotation of the side flanges with the roller surface, the wear trajectory of the high-pressure zone side guard is changed, and the relative motion between the high-pressure zone material and the corresponding side guard device is almost eliminated, resulting in a significant reduction in wear. Significantly improved the service life of the side panel.
