Bulk Technik cc
The Bulk Technik designed dosing feeder is suitable for micro dosing of granular products. The dosing feeder essentially consists of a tubular screw flight that is driven by a geared motor and feeds product at the required rate into the discharge adaptor. A mechanical agitator arm, turns in the feeder housing above, thereby gently mixing the powder to ensure that it flows freely into the feed screw and thereby providing a constant product flow for accurate dosing. The agitator arm is driven via a gear wheel that is coupled to the screw feeder.
Both the screw flight and the agitator arm have stuffing box-type seals and are mounted with outboard plummer block bearings. The dosing feeders are manufactured from mild steel components, however, we can offer an option where all wetted surfaces are manufactured from stainless steel.
The geared motor can be supplied with a VSD so that the feed rate can be varied for a specific conveying range. The dosing feeders are usually supplied with custom sized screw flights as well as a geared motor selected to provide the correct dosing capacity. Typically these vary from 10 kg/h up to 500 kg/h, however, other feed rates can be custom designed.
Bulk Technik offers complete dosing stations complete with a de-bagging unit that incorporates a dust filter and access platform to elevate the discharge of the dosing feeder so that it can, for example, gravity feed into a mixing tank. The systems are typically used when product is supplied in 25 kg bags.
