Dry material feeder

Product information "Dry material feeder"

Optimum dosing of pourable substances

Dry material feeders are used to precisely dose the pourable substances required in chemical and process engineering. Dosing is possible if the particles of the substance are fine as dust, pellets, flakes or short fibres.
The devices are volumetrically conveying and equipped with dosing screws (screw spindles) for material transport. They make no reference to the dosed mass. Therefore, it must be taken into account during use whether the bulk density is permissible for the process or must be changed by suitable measures. The bulk density influences the amount of material that is transported per dosing cycle, as it determines how densely the material is packed in the feeder. Exact knowledge of the bulk density is therefore crucial to ensure consistently precise dosing.
Properties of our dry material feeders
reliable and precise dosing of, for example, burnt lime, polyelectrolytes or activated carbon.

* The maximum flow rate is a value determined by means of a test bench and measured with water at a liquid temperature of approx. 20 °C . The measurement is taken at the pressure joint of the pump, without hose, nozzle or flow meter. The achievable flow rate in use is lower and depends on the individual application, the liquid properties and the configuration of the pump. The max. delivery head also depends on the pump design, motor and fluid. The viscosity values are determined with oil.

** Test assembly: Medium water / diesel, flow in preferred direction, settling section 0.2 m upstream and downstream of flow meter
