For Precision Batching of Bulk Materials under repeatable accuracy and time control is offered with Main and Metering Screw combination having Quick Shut Off Valve with Coarse and Fine Dosing capability. Metering Screws are optionally provided with Variable Speed Drive Motors with Servo Ventilation Cooling Fans for operation under Super Fine Mode to achieve Critical Accuracy.
Special construction of Screw Flights — Short, Tapered, Expanded Pitch are used for materials of High Compressibility Factors or Hygroscopic nature. Wear Resistant HARDOX or Hard Faced Flights are used for Abrasive materials. Several different types of Shaft Seals are used for Fine Powders.
