Introducing the Flexible Paddle-Massaged PUR Hopper LIW Feeder: a robust, efficient solution designed to deliver unparalleled precision in your material handling needs.
General Introduction
Loss-in-weight feeders are your go-to solution for small to medium feeding ranges, offering unbeatable precision under ideal ambient conditions. Their versatility allows them to handle bulk solids, liquids, and even poorly flowing materials effortlessly. These feeders are indispensable in continuous processes, such as feeding extruders that demand high short-term feeding consistency. Moreover, they find extensive applications in the food industry and laboratories, facilitated by suitable storage containers and tailored feeding mechanisms. Designs range from compact units to modular concepts, aligning with varied usage scenarios.
Principle
As material flows through the feeder, the system's weight decreases. The loss-in-weight feeder controls adjust the feed rate to ensure the speed of weight loss matches the desired feed rate, constantly monitoring the material flow to maintain accuracy.
Every component, including the feeder, hopper, and material, is continuously weighed during operation to ensure precise feeding.
Gravimetric feeders experience minor feed rate fluctuations, resulting from variations in auger filling capacity and material bulk density. These fluctuations are mitigated by adjusting the auger speed, ensuring consistent 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, and pumps. They also include scales or load cells, and loss-in-weight controllers to maintain precision.
Nanjing Pege's loss-in-weight feeders are optimized for the compound industry. They offer flexible installation options and come in various feeder and hopper sizes to fit any space. Vertical container walls maximize space utilization and enhance bulk material flow. The off-center auger setup allows up to six feeders to be positioned adjacently. Additionally, drive and auger configurations can be customized during assembly.
Material Applicable
Ideal for Resin Particles, Resin Powder, Calcium Carbonate, and Glass Fibers.
Suitable for handling Talcum Powder and Titanium White Powder.
Effective for Carbon Black and Flame Retardant Antioxidants.
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.
