Gravimetric Powder Micro Doser, dosing machine, loss-in-weight feeding system, Weightless Feeder, Twin Screw Dosing System,
screw conveyor
Working Principle: When the material is fed through the feeder, the weight of the system decreases. Controlling the loss-in-weight feeder changes the feed rate and as a result the speed of weight loss matches the desired feed rate. Loss-in-weight feeder controls continuously check whether the material is flowing.
All components and/or any product they contain is continuously weighed during operation: the feeder, the hopper and the material.
Gravimetric feeders, for instance, have slight fluctuations in their feed rates. These fluctuations occur in the filling capacity of the augers and in the bulk density of the material. These are compensated for by adapting the auger speed in order to ensure the product is dispensed evenly.

Twin screw weightless feeder
1. Suitable for powders with poor fluidity, fiberglass, sheet materials, etc., more uniform than single screw feeding
2. Horizontal and vertical mixing devices can be selected to solve the problem of material bridging
3. Corresponding feeding screws can be selected according to different materials
4. Drive motor: Variable frequency motor or servo motor optional
5. The improved design facilitates the installation and disassembly of the screw, and there will be no accumulation of materials at the root of the screw
6. The feeding section is easy to disassemble, clean, replace, and maintain
7. Material in contact with material: 304/316 stainless steel
8. Seals: silicone rubber, nitrile rubber, polytetrafluoroethylene
9. The hopper capacity can be customized
10. Aluminum transmission box for better heat dissipation
11. Dust proof weighing platform to avoid dust interference
