The working principle of a vertical mill, the main structure and function of the main structure of the separator vertical mill, roller device, disc apparatus, pressure equipment, part of the reducer, motor, housing and so on. Separator is to determine the thickness of the important parts of flour products, which consists of variable-speed drives, the rotor, the guide blades, housing, meals blanking cone hopper, the outlet, etc., is an efficient, energy-saving, quick The separator apparatus. Roller is the main component of the material for rolling mill, which is installed in the mill bent arm, under the action of external forces, pressed against the disc of material, driven disc, the roller along turn to, so that the material is compacted and crushed. Disc fixed to the output shaft gear, disc upper part of the bed, the bed material with an annular groove in the annular groove material is crushed by the roller. Provide pressure roller grinding unit pressurized device, which consists of high-pressure oil station, hydraulic cylinder rod, storage, etc., can exert enough pressure on the roller so that the material crushed. Gear transmission of power is a major component, the rotational speed of the disc is the gear output pumping speed. 2, the working principle of the motor through reducer drive disc rotation, while the hot air from the air inlet into the vertical mill, the material falls on the central disc from the discharge port, due to the centrifugal force, the material moves from the disc center to the edge of the disc, through the annular disc When the groove by rolling mill rolls and grinding, pulverized material prepared to continue to move the disc edges until it is taken away by the air flow at the air ring, and large particulate material falling onto the disc and continue to crush. Airflow through the upper material into the separator, the guide vanes in the role, plastic bucket from the cone fell on the disc, together with the air of the powder mill, the dust collection system, a powder was collected on is the force grind mill products. Material in contact with the housing process gas is dried to achieve the required product humidity. By adjusting the angle of the stripper-guide blade (small vertical mill not adjustable) and separator rotor speed, it will reach the desired thickness of the product.
