Grain processing machinery for mixing, sorting and grading. Various types of grain cleaning machines use different working principles to separate grain particles from impurities. The separation methods of commonly used Paddy Separator(LIANGGONG) https://www.china-zjlg.com/product/paddy-separator-machine/ by particle size, separated by specific gravity, separated according to the natural characteristics of impurities, separated by shape, separated according to the natural characteristics of impurities, separated according to gas flow characteristics, and separated according to the degree of frictional impact. Separation by particle size A woven wire mesh or punched metal plate is used as the screen surface. It can be divided into a flat screen surface of reciprocating vibration or plane rotation and a cylindrical screen surface rotating around the shaft. There are two types of equipment depending on the size of the sieve holes on the sieve surface relative to the grain size: 1. The sieve holes are slightly larger than the maximum diameter of the grain particles. 2. The mesh size is smaller than the minimum grain diameter, such as reciprocating shaker, flat rotary screen and high speed vibrating screen. Small impurities in the grain particles can be removed through the sieve holes, and the grain is discharged as a sieve. The sieve body of the high-speed vibrating screen has a circular motion of small amplitude in a vertical plane under the action of the centrifugal inertial force generated by the high-speed rotation of the balance weights on both sides, and has 2 to 4 sieve faces. It is used to separate the scorpion in rice, and the effect is better. Click Paddy Husker https://www.china-zjlg.com/product/rubber-roller-husker/ to learn about more information.
