Pneumo-sorting table SPS


Quick Overview

Pneumo-sorting table SPS is used in cleaning of the grain legumes, oilseeds and cereals from hard-separable impurities which differ from the main grain in shape, surface properties, and specific gravity. Pneumo-sorting table can also be used for the selection of mineral impurities.

Pneumo-sorting table SPS is used in cleaning of the grain legumes, oilseeds and cereals from hard-separable impurities which differ from the main grain in shape, surface properties, and specific gravity. Pneumo-sorting table can also be used for the selection of mineral impurities.

Using this machine the separation of stones and other impurities that differ from the grain in shape, specific gravity and surface properties is made successfully. The grain material should be cleaned in a sieve-air separator and grain separator beforehand, and have the necessary humidity degree. The use of the pneumo-sorting table is advisable in grain cleaning production lines and in grain processing plants.

Process description:  

The product enters the machine through the suction inlet, due to a special valve it is distributed evenly on the deck. The valve eliminates the possibility of suction of air through the suction inlet into the working area of the machine. The body of pneumo-sorting table is trimmed with a special metal mesh which performs the longitudinal oscillatory motion.

Due to the regular vibration of the working surface, and the air flowing through the spout to the throttle valve and the longitudinal and lateral inclination, a quality product sorting is provided. All heavy impurities remain on the mesh and go through the exit nozzle under the longitudinal motion. As for the light particles, all of them, under the action of air  are directed to the sides of the deck and are discharged through the nozzles.

Heavy impurities are directed the opposite way - to the horizontal valve deck. This valve allows to create a countercurrent circulation of adjustable speed air flow. With this circulation grains can be separated from the stones that fall to the container bottom. Air participating in the stratifying process, may contain the lighter product fractions or dust and thus is subjected to a thorough cleaning in the filter or cyclone.
