Volumetric Screw Feeder (Doser)

Digidale Engineering offers Volumetric Screw Feeders (Doser), Model Digi-VSF. They are used in a wide range of application for handling most materials at any desired rate. These address classical powder discharging problems such as bridging, flushing, rat holing, degradation and segregation. Metering dry materials accurately and consistently is a priority in any dry material processing system and these ensure smooth movement throughout the feed process. Working on the principle of mechanical fluidisation, these dosers guarantee the problem free discharge in continuous as well as precious batch operation of granular and powdery products such as flour, milk powder, salt, starch, flakes, coal, pallets, bentonite, washing powder and agglomerates, etc. It is a simple, low cost ruggedly built volumetric screw feeder that provides extremely accurate, dependable metering of wide range of dry particulate materials. The geometry of the trough and screw with agitator effectively de-aerate and contain the powder on initial fill cycle to help prevent flooding. Virtually maintenance free, the model Digi-VSF has only five moving parts - drive, coupling, screw and two bearings. An agitator/conditioner screw available in all feeders fills the screw completely resulting in desired feed accuracies. Standard units provides feed rate from 5 kg/hr to 60 tonne/hr. A 100 litre hopper with 70° sloped sides and large rectangular outlet provides capacity for most surge conditions.
