Industrial loss in weight feeder system
Industrial continuous Loss-In-Weight Feeder system
The Loss-In-Weight Feeder system,also named weight feeder,is a continuous weigh feeder system for powder material feeding and discharging like cement, lime powder, coal powder etc. fine material.Since the weight-loss control is done in the hopper, it can have a high control precision. What’s more, the structure is easily for sealing, so the Loss-In-Weight has better performance in powder weight control compared with the spiral scale.Material weight is controlled by controlling the screw conveyor through controlling the weight loss rate in the hopper. The screw conveyor will stop conveying material when all material is charged from the hopper, and the pneumatic gate valve is open for feeding material. Material feeding will stop when feeding load reaches the upper weight limit. Rapid feeding can lengthen the feeding time and improve the weighing accuracy and control accuracy.
Features
1) The screw conveyor is of invertor control so that the R.P.M can be adjusted according to the production requirement within its capacity range.
2) The material weight control is under Mettler Toledo PowerMount weighing module and IND570 weighing terminal. Refer to the manual of PowerMount module and IND570.
