Dosing screw

The dosing screw DN200 can now be ordered as a separate component independent of a weighing system. This screw can be used wherever powdery, heavy flowing / shooting products have to be filled and dosed. The speed of the dosing screw can be infinitely controlled via a frequency converter provided by the customer. A possible trickling or overshooting is prevented by the corresponding closing rotary flap.

In combination, screw with dosing flap, a lot of difficult flowing products can be handled.

• Tubular screw conveyor with asymmetrical screw shaft (one-sided bearing, easy disassembly)

• Inlet and outlet flange round
• Three-phase geared motor, swivel-mounted 1.1KW
• SEW frequency inverter
• Closure Dosing rotary flap, pneumatically operated with pneumatic valve control analog position sensor 0-90 degrees +/- 0.1 degrees

The control is carried out by the customer via a Siemens SPS. The function block is supplied for an S7 control. On request, the complete control system can also be supplied
