OVERVIEW

The loss-in-weight feeder adopts silo metering weighing technology, which uses weighing sensors to weigh the silo. As a quantitative weighing and feeding equipment, it is applied in dynamic continuous weighing processes. It can perform weighing and quantitative control on materials requiring continuous feeding, and is equipped with displays for material instantaneous flow rate and cumulative flow rate.Based on the measurement principle, the loss-in-weight feeder not only supports commodity calibration but also enables online calibration to optimize production operations. Specifically, its accuracy is measured and compared by calculating the difference between the upper and lower net weights of raw materials in the metering verification bucket and the current value of the loss-in-weight feeder's total flowmeter. This calibration method is characterized by simplicity and clarity, being cost-effective for industrial users.

Operating Principle:

The loss-in-weight feeder achieves the purpose of quantitative feeding by controlling the discharge screw conveyor or electric vibrator based on the reduction rate of material weight in the weighing hopper.When the material in the weighing hopper reaches the lower weighing limit, the discharge screw conveyor maintains a fixed discharge volume according to its current rotation speed. At the same time, the material in the silo is controlled to quickly flow into the weighing hopper, and the feeding stops when the material reaches the upper weighing limit. This rapid feeding method shortens the feeding time and improves the weighing accuracy and control precision of the loss-in-weight feeding system.

Maintaining:

  1. 1.The loss-in-weight feeder should be used in a dry indoor environment and should not be operated in places with acidic or corrosive gases that may damage the equipment—prolonging the service life of the industrial weighing feeder.
  2. 2.After using the loss-in-weight feeder, the rotating drum should be removed for cleaning, and reinstalled after cleaning to prepare for the next use—ensuring hygiene and performance for subsequent operations.
  3. 3.Mechanical parts should be inspected monthly, including checking the flexibility of moving parts such as worm gears, worms, bolts on lubricating blocks, and bearings, as well as their wear conditions. Damaged parts should be repaired promptly to avoid affecting production line stability.
  4. 4.If the loss-in-weight feeder is out of service for a long time, it should be thoroughly cleaned. The smooth surfaces of mechanical parts should be coated with anti-rust oil and covered with a cloth cover to prevent corrosion.
  5. 5.If the drum moves back and forth during operation, adjust the screws on the front bearing to the appropriate position. If the gear shaft moves, adjust the screws behind the bearing bracket to the correct position. The gap should be adjusted so that the bearing makes no noise, and the pulley should be turned by hand to ensure proper tightness—excessive tightness or looseness may cause damage to the loss-in-weight feeding equipment.
