Screw Feeder
Precision batching of bulk materials under repeatable accuracy and time control is offered with this Main and Metering Screw combination with 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.
The Main Screw is available from 150mm to 600mm diameter with capacity ranges from 500kg/h to 50,000kg/h. The Metering Screws with diameters 80mm to 150mm delivers precisely over 50g/min to 5000g/min under optional Variable Speed Drives.
Both the Main & Metering Screws operate up to a preset target of 90 — 95% of the Batch Weight in “COARSE” mode. The Main Screw then turns off with an optional cut-off valve, shutting any accidental overflow of materials. The Metering Screw continues to discharge material in the “FINE” mode. For very high accuracy, the speed of the Metering Screw is further reduced by a Variable Speed Drive precision dosing in “SUPERFINE” mode for a small percentage of the Batch Weight.
Material Characteristics Tests available for correct selection of Screw construction of various grades. Optional accessories in stainless steel, carbon steel like Flexible Connectors, Load Cells, Weighing Controllers, Dust Filters are available for complete Batching Operation.
Conveyability Tests with materials provided by the customer are available at our Testing and R&D Facilities.
