K-TRON SODER SWB-300 Weigh Belt Feeder

This K-TRON Weigh was used in a confectionery plant. Use weigh belt feeders for gravimetric feeding at higher feed rates or where low headroom is a problem. Especially at high feed rates, a weigh belt feeder offers lower initial cost than a loss-in-weight feeder with equal throughput.
Materials Fed: free-flowing pellets, powders, fibers and friable materials.
The Smart Weigh Belt Feeder is used for continuous controlled gravimetric feeding of bulk materials. The unit can also be used for gravimetric batch feeding or for continuous metering of bulk material flow

Feed rate
Belt speeds are controlled to within +/- 1 RPM over a 100:1 range from full motor speed.
Material bulk densities can range from 0.5 to 2.5kg/l (31 to 156 lb/ft3)
Material particle size can be a max. of 10mm (0.4")
Component A is specified in this spec sheet.
SWB-300 (belt width 300 mm)
Material flow onto the belt / weigh bridge is set through a stainless steel inlet chute with adjustable gate height. Side skirts prevent material spillage on the conveyor.
Material weight on the primary weigh deck and belt tare weight on the secondary weigh deck are determined by K-TRON's patented SFT III weighing technology with vibration and temperature immunity, zero deflection and 1 part in 1 million resolution.

The control employs belt segmentation and weight shift technology to achieve control of material rate at the discharge point.

The unit can be supplied with pre feeder units such as rotary valves, screw feeders or vibratory trays.(from agent only)
