Worm screw feeder MAR series

powdermotorized

Volumetric Feeders fall into 3 categories: Batch Feeders by controlling time a weight batch (Kg) is dosed. Rate Feeders by controlling speed a variable speed rate (Kg/hr) is dosed. Recipe Feeders by controlling both speed and time a variety of recipes can be delivered already mixed. The RPM of the screw feeders can be adjusted by means of: Continuous mechanical variable-speed motors with manual or electrical control: Minimum flow rate equal to 1/5 of maximum flow rate. Continuous hydrostatic variable-speed motors with manual or electrical control: Flow rate having maximum value of approximately 0. Gearmotors with motors piloted by vector inverters and additional power ventilation, when necessary, with minimum flow rate equal to at least 1/10 of maximum flow rate.
