Mechanical Discharge Aids

Mechanical discharge aids devices of propriety designs are being employed to move the bulk solids out of silos, stocking and other storage facilities. Broadly speaking, these mechanical devices either rely on extracting stored bulk material towards the outlet or agigated/condition the material for reliable flow under gravity.

Classification of mechanical discharge aids

Material extractors are designed to suit the existing hopper or silo designs. Consideration is given to the flow property of bulk solids and the extent of consolidation with respect to time. These devices are expensive, and can only be viable if storing a large quantity of solids.

Fixed Configuration

• Single or Multiple Screws in Parallel
• Circular Discharger
• Rotary Table discharger

Dischargers with Moving Configuration

• These types consist of moving dischargers in addition to rotating on their axis, sweeps or traverses across the cross section of the storage units.
• Rotating screws in flat bottom silos
• Rotating screws in hopper
• Screw-tube type dischargers
• Plow discharger
• Sliding frame in flat bottom silos
