Twin-screw feeder for powders and micro-granules
Ideal for handling poorly flowing powders and granules, this advanced twin-screw feeder ensures precise and consistent dosing, addressing challenges in bridging and flow interruption.
Feeds and Meters Challenging Powders and Granules
The ZD 12 B from Three-Tec is a volumetric twin-screw feeder designed specifically to tackle the challenges of handling poorly flowing powders and bridging materials. It employs a discharge aid and bridge breaker mechanism to ensure consistent material flow, making it ideal for feeding and metering processes in chemical, pharmaceutical, and food industries. Offering throughput rates from 0.2 to 57 liters per hour, the feeder can accommodate both AC three-phase and servo motor options, enabling precise adjustment of feeding speed between 4 and 750 revolutions per minute. Its flexible design includes horizontal or vertical discharge pipes and a dosing hopper capacity of either 4.5 or 8.5 liters. The ZD 12 B integrates seamlessly into existing production lines with its continuous operation capability, ensuring efficient dosing of products like protein powders, pharmaceutical ingredients, and fine polymers. Constructed for durability and efficiency, this feeder is a crucial component for overcoming the operational hurdles often encountered in powder processing sectors.
