The twin screw loss in weight metering feeder system is normally supplied with a standard Rospen metering screw feeder either single or twin screw from 12mm to 250mm dia and output range from 1.0kg/hr to, in excess of 100,000kg/hr.The selection of the correct type of feeder from our extensive range is determined primarily by the type and specification of the material to be handled. Both single and twin, screw feeders are equally as efficient, with the single screw mechanically simpler and therefore, more economical. Both units share the following features and benefits.

gravimetric system feeders a certain material gravimetric to a process per unit of time (such as cubic feet per hour). Thegravimetric screw feeder consists of a hopper, material discharge device and controller. This is the most common kind of gravimetric feeder, and its material discharge device is a screw that rotates at a constant speed in order to meter material at a predetermined gravimetric-per-revolution discharge rate from the hopper to the process. The controller monitors and controls the feeder’s screw speed, which governs the material discharge rate.
