1. Separate plant vibration noise from true weight loss. A LIW feeder's operation depends on accurate measurement of the material weight in the hopper, so the feeder and weight-sensing device must be isolated from external forces and vibration. Position the feeder so that no external forces or friction can influence weighing. Isolate

The PFISTER DRW is designed with minimal moving parts. Less moving parts, less maintenance. And what little there is to maintain can be accessed from the outside, meaning the work can be done in situ with little risk to maintenance personnel. No cleaning is required, so you can expect high availability from your rotor weighfeeder.

The filter should be programmed to recognize also strong disturbances and take action in consequence. If the feeder is not anymore able to calculate accurately a loss of weight, it will turn automatically to volumetric feeding, fixing the speed of the dosing tool.Such measure is an approximation and can only be acceptable if the feeder stays in volumetric mode for a short time.

Loss-in-weight feeders consist of a hopper with a dosing unit, typically a screw or vibrating unit, all placed on load cells monitoring the material output of the hopper during dosing. Dosing is measured in kilograms per hour and the controller adjusts the speed of the dosing unit to match the setpoint, ensuring consistent product flow. ...
