These works on the principle of reducing the pipeline cross sectional area in the region where the material is fed from the supply hopper. There are no moving parts in this feeding device which has certain advantage with regards to wear problems. No Air leakage in opposition of material feed. A consequence of the reduction in flow area is increase in the entraining air velocity & corresponding decrease in the pressure in the region These feeders are usually incorporated in systems that are required to convey free flowing materials at low flow rates. Venturi Eductor mainly comprises of Eductor Body Nozzle Diffuser   Salient Features of Venturi Eductor Conveying Solids with No Moving Parts. Small , occupy less space & cheaper No Maintenance No Blow-Back Minimum Product Degradation Venturi Eductors are used to feed bulk solids such as  powders, powdered spices, pellets, flakes, rubber crumb, Styrene Butadiene Rubber and particulates having low bulk density,  into Lean phase conveying systems Eductors are attractive to install below other solids processing equipment because, by creating suction at the product inlet, they enable dust-free material conveying systems. These are commonly installed beneath: Feed Hoppers, Bins, Silos, and bag unloading stations. Bag houses/Dust Collectors Screens/Classifier Outlets Mixers, Grinders, and Mills

Sugar handling system it is temporarily stored. Cyclone separators are use for cyclonic action to separate dust particles from the gas stream. In a typical cyclone, the dust gas stream enters at an angle and is spun rapidly.

Baggage handling system has been captured by a dry dust collection system, it must be separated, collected, and disposed of. The dust collector separates dust particles from the airstream and discharges cleaned air either into the atmosphere or back into the workplace.

Vacuum conveying system Materials of construction are selected to suit the application (MS SS304 SS316), Screw Conveyors are usually designed to suit specific applications as per Customer Requirement.

Powder transfer system There are no moving parts in this feeding device which has certain advantage with regards to wear problems. No Air leakage in opposition of material feed.

Slide conveyor a very slight angle (as low as 1.5 ). Pressured air is injected into the lower chamber which then permeates through the media and "fluidizes" the product. The product then behaves like a fluid and "flows" down the length of the chamber. The excess air is vented through a dust collector
