Weiss - Model T220T -Transport Worm Screw
The transport worm screw is designed for transportation of fine grained material (13x13x13 mm) of maximum 35 % moisture. The material, which is bio fuel, must be suited for this type of transport handling. The transport worm screw can be connected to the out-feeder type NFF-NFU or to a stoker. The transport worm screw is equipped with a direct drive, where the connection between the worm screw and the gear motor is assembled by a chain coupling.
The transport worm screw is provided with variable RPM for measuring the amount of fuel flow in a time unit. The material flow is adjusted by changing the frequency of the motor.
If the transport worm screw is installed in connection with a stoker unit, the fuel will often be transported through an angle piece. The transport worm screw has an inlet and outlet. On the outlet, a micro switch with a sensor is installed which will be activated in case of material overflow. A cleaning door is placed on the outlet of the screw.
