Flexible Paddle-Massaged PUR Hopper LIW Feeder
General Introduction
Loss-in-weight feeders are versatile instruments, perfect for small to medium feeding ranges. Operating with outstanding precision under optimal conditions, these feeders are highly adaptable, efficiently handling bulk solids, liquids, and even poorly flowing products. They are vital in many continuous processes, such as feeding extruders where high short-term feeding consistency is crucial. Additionally, they find applications in the food industry and laboratories, thanks to suitable storage containers and custom feeding devices. Designs range from compact to modular, tailored to specific uses.
Principle
As the material passes through the feeder, the system's weight decreases. By controlling the loss-in-weight feeder, the feed rate is adjusted so that the speed of weight loss aligns with the desired feed rate. Continuous monitoring ensures material flow is consistent.
During operation, all components and any contained products are continuously weighed: including the feeder, hopper, and material.
Gravimetric feeders experience slight feed rate fluctuations due to variations in auger filling capacity and bulk material density. These fluctuations are mitigated by adjusting auger speeds, ensuring even product dispensing.
Composition of Loss-in-Weight Feeder
Loss-in-weight feeders for bulk materials comprise storage hoppers, controlled feeding devices like augers, screws, agitators, pumps, and also include scales or load cells, alongside loss-in-weight controllers.
Nanjing Pege's loss-in-weight feeders are tailor-made for the compound industry. They feature flexible installation options, varied feeder and hopper sizes to suit all spaces. Vertical container walls maximize space utilization and enhance bulk material flow. The off-centre auger arrangement permits positioning of up to six feeders side-by-side. Furthermore, the drive and auger setup can be customized during assembly.

Features
|
Suitable for all-purpose bulk material, especially for the powder material with humidity and low flowability.
The cantilever sling-type weighing scale supports the storage hopper, which has the characteristics of vibration reduction and anti-level interference. This design can effectively shield the non-weight value interference from the vibrator and measure the flow of the system more accurately.
All contact with materials is SUS304 with inner mirror surface.
Gentle feed capability by paddling flexible hopper with external agitation.
Easy to disassemble and to clean, convenient for maintenance.
No direct touch between stirring unit and material ensures no damage on the materials.
The stirring and feeding motors are separated, and the speed can be adjusted separately.
The electronic control system reserves an Ethernet communication interface for remote control.
