Q:What is the working principle of the loss-in-weight feeder?

The system continuously weighs the feeder, hopper, and material. It controls the feed rate by adjusting the auger speed to match the desired weight loss, compensating for fluctuations in bulk density and filling capacity.

Q:What materials are used for parts contacting the product?

The material in contact with the product is made of 304 or 316 stainless steel. Seals are made of silicone rubber, nitrile rubber, or polytetrafluoroethylene.

Q:Can the hopper capacity be customized?

Yes, the hopper capacity can be customized to suit specific application needs.

Q:What types of motors are available for this feeder?

Both variable frequency motors and servo motors are optional for the drive motor, allowing for precise speed adjustment.

Q:What is the warranty period for this equipment?

We provide a 1-year warranty for the equipment.
