Introducing the revolutionary Flexible Paddle-Massaged PUR Hopper LIW Feeder: a robust and highly efficient solution engineered to deliver unmatched precision for all your material handling requirements. Experience excellence and precision with each use.
General Introduction
Loss-in-weight feeders stand as the quintessential choice for small to medium feeding ranges, offering exceptional precision in optimal ambient conditions. Their remarkable versatility empowers them to effortlessly manage bulk solids, liquids, and even challenging poorly flowing materials. These feeders are indispensable in continuous processes, such as feeding extruders where high short-term feeding consistency is paramount. They find extensive application in the food industry and laboratories, thanks to adept storage containers and customized feeding mechanisms. With designs ranging from compact units to modular concepts, they cater to diverse usage scenarios seamlessly.
Principle
As material traverses the feeder, the system diligently tracks decreasing weight. The loss-in-weight feeder controls adeptly adjust the feed rate, ensuring that the speed of weight loss aligns perfectly with the desired feed rate. Constantly vigilant, the system monitors material flow to guarantee unwavering accuracy.
Every component, including the feeder, hopper, and the material itself, is meticulously weighed continuously during operation, ensuring unerring precision in feeding.
Gravimetric feeders may encounter minor feed rate fluctuations due to variations in auger filling capacity and material bulk density. These are skillfully mitigated by adjusting the auger speed, ensuring a consistent and reliable product dispensing process.
Composition of Loss-in-Weight Feeder
Loss-in-weight feeders for bulk materials are meticulously composed of storage hoppers, precisely controlled feeding devices like augers, screws, agitators, and pumps. They are also equipped with scales or load cells and loss-in-weight controllers, all designed to maintain impeccable precision.
Nanjing Pege's loss-in-weight feeders are expertly optimized for the compound industry. They offer versatile installation options and come in an array of feeder and hopper sizes to seamlessly fit any space. The innovative vertical container walls maximize space utilization and enhance bulk material flow. Moreover, the off-center auger setup accommodates up to six feeders positioned adjacently. Drive and auger configurations are customizable during assembly to meet specific needs.
Material Applicable
Perfectly suited for Resin Particles, Resin Powder, Calcium Carbonate, and Glass Fibers.
Optimally handles Talcum Powder and Titanium White Powder with ease.
Highly 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.
