Description

Flexible Paddle-Massaged PUR Hopper LIW Feeder

General Introduction
Loss-in-weight feeders can be used for both small to medium feeding ranges. They work with extreme precision under optimum ambient conditions. They are very flexible and can handle bulk solids, liquids and even poorly flowing products. They are used in many continuous processes such as feeding extruders requiring a high level of short-term feeding consistency. They are also used in the food industry and in laboratories by means of appropriate storage containers and adapted feeding devices. The design varies from compact constructions to modular concepts depending on usage.

Principle
When the material is fed through the feeder, the weight of the system decreases. Controlling the loss-in-weight feeder changes the feed rate and as a result the speed of weight loss matches the desired feed rate. Loss-in-weight feeder controls continuously check whether the material is flowing.
All components and/or any product they contain is continuously weighed during operation: the feeder, the hopper and the material.
Gravimetric feeders, for instance, have slight fluctuations in their feed rates. These fluctuations occur in the filling capacity of the augers and in the bulk density of the material. These are compensated for by adapting the auger speed in order to ensure the product is dispensed evenly.

Composition of loss-in-weight feeder
Loss-in weight feeders for bulk materials consist of storage hoppers, controlled feeding devices such as augers, screws, agitators, pumps as well as scales or load cells, loss-in-weight controllers or rather loss-in-weight feeder controllers.
The Nanjing Pege's loss-in-weight feeders have, for instance, been optimised for the compound industry. Flexible installation options, different feeder sizes and hopper sizes are adapted to each available space. Vertical container walls mean that virtually every millimetre is used to the max and impact positively on the bulk material flow. Thanks to the off-centre auger arrangement, up to six feeders can be positioned next to each other. The drive and auger setup can still be customised during assembly.

Flexible Paddle-Massaged PUR Hopper Feeder (FLEXHOPPER)

Material Applicable
Resin Particles, Resin Powder, Calcium Carbonate, Glass fibers
Talcum Powder, Titanium White Powder
Carbon Black, Flame Retardant Antioxidant
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.
