Product Description

Single Screw Loss-in-weight Feeders

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.

1,Application field
Resin granules, powder and pellet blendings.

2,Features
  • The cantilever sling-type weighing scale supports the storage hopper, which has the characteristics of vibration reduction and anti-level interference. It can effectively shield the non-weight value interference from the vibrator and measure the flow of the system more accurately.
*The Stirring and Feeding are separated and driven independently to ensure that the feeding speed is sufficiently ductile. Various speed ratios are selected according to the characteristics of the material, increasing the flexibility of customer formula adjustment.
*Feeding motor uses servo motor + planetary reducer, precise control, light weight, small vibration, low speed constant torque, wide flow range, double the flow range than AC motor.
* The output bearing seat, screw and sealing device can be directly pulled out of the hopper for easy maintenance and cleaning.
* The motor and the screw are driven by PTFE gear. When the screw is stuck by foreign matter, it can play a transitional buffer function, giving the motor an over-torque shutdown alarm time to prevent the gearbox or the screw from being damaged by impact deformation.
* The electrical control system reserves the Ethernet communication interface for remote control.
* PLC, MCU and industrial computer are available for customers to choose.
* Can provide the program source code for accessing the client's upper computer and the factory centralized control system.]

FAQs on loss-in-weight feeders
 
  1. How does loss in weight feeder works?
Gravimetric loss in weight feeder is an instrument that is important to control and measure the speed of a substance in an instrument system. This equipment can handle the bulk solids. It allows the solid to discharge at a constant weight per unit time. The unit of measurement is kg/min or Kg/hour. The signal about the weight is used as a system of feedback control. It controls and monitors the feed rate that enters a instrument. The weighing systems include several examples such as platform scales, load-cells, weigh hoppers, etc. Depending on the overall process, the gravimetric feeder may be a loss-in-weight system or a gain-in-weight system.
  1. What are the most important benefits the gravimetric feeder can give to you?
To ensure excellent quality of final product by accurately metering the bulk ingredients.
To reduce the labor cost and improve labor work environment
To Improve product stability
Reduce dust pollution and be more environmentally friendly
 
  1. What is general accuracy rate of the good loss in weight feeder?
Our general feeder's feeding accuracy rate can be 0.5%. The micro twin screw loss in weight feeder accuracy rate can be up to 0.3%.
 
  1. What is the lead time for the machine?
Generally, one group of 3 sets feeders production time will be about 60 days.
 
  1. How do the gravimetric loss-in-weight feeder packed and shipped?
The loss in weight feeders are well packed and fastened in the plywood carton and then delivered to the seaport for sea transportation to the countries all over the world.
