Main Functions and Working Principle of Vertical Roller Mill

Motor through reducer drive disc rotates, while the hot air from the air inlet into vertical roller mill, the material falls under the spout from the central disc, due to centrifugal force, the material moves from the disc center to the edge of the disc, the disc past the annular groove on the subject rolling mill rolls and grinding, crushing the material prepared to continue moving towards the edge of the disc until it is taken away by the wind flow annulus, while large particles of material falling onto the disc again to continue crushing. Material into the gas stream through the upper part of the separator when, under the action of the guide vanes, the plastic bucket from the cone falls on the disc, the grinding of powder together with air, is collected in the dust collector system, the powder is collected on the is the force grind mill products. Materials in contact with the housing process gas is dried to achieve the required product humidity. By adjusting the angle of the blades oriented separator (small vertical roller mill is not adjustable) and separator rotor speed, will reach the desired thickness of the product.
Disc of vertical roller mill fixed to the output shaft of the reducer, the upper portion of the disc material bed, the bed material has an annular groove, the annular groove in the material is crushed by the grinding rolls. Provide pressure grinding roller mill components pressurized device, which consists of high-pressure oil station, hydraulic cylinder rod, accumulator, etc., can exert enough pressure to make the material grinding mill rolls. Reducer is a major power transmission components, disc rotation speed reducer output is pumping speed.
