[PSD] DryFeeders_[UK] DryFeeders 26/09/11 09.07 Pagina 1 DRY MATERIAL FEEDING Dry material feeding and PREPARATION SYSTEMS AND Preparation Systems POWDER FEEDERS Powder volumetric feeders are designed to provide a constant and accurate flow for any grains, fibers and powders. Powder feeders are completely made in stainless steel SS304. VG100 Construction Features Hopper: It was two vertical walls ensure even flow of the products; available in 50 and 100 liters versions; optional: supplementary mixer or vibration; internal polishing, level indicator. Gearbox: motion transmission is carried out by a chain/pinion, which are connected to metering helix and to agitator rotates; optional: FPM seals-ring. Speed variator: (manual adjustement) it provides capacity control, when feeder is running between 10 and 100% of maximum delivery; 3-phase motor, 0,18 kw, insulation class F; optional: coaxial gear for constant feeding, gravitation indicator. Metering helix: the accuracy depending from characteristics of products, from 0,5% to 3%; optional: reinforced metering helix, solid metering helix, extended helix and discharge tube. OPTIONAL: Thermostat resistance: to avoid product agglomeration, caused by humidity. Dissolver: to ensure a perfect dilution of product in water, thanks to a specific design and to a water-flow control. 03 Flow rate min. (l/h) Flow rate max.

OPTIONAL: Thermostat resistance: to avoid product agglomeration, caused by wetness. Plexiglas discharge: to canalize the product without useless wastages. Dissolver: to ensure a perfect dilution of product in water, thanks to a specific design and to a water-flow control. 03 Flow rate min. (l/h) Flow rate max.
