To strengthen our competence and leading position in the gravimetric weighing field, we integrated our profound technology and talents to better improve our design and manufacturing competence.

Composition of Gravimetric Loss-In-Weight Feeder

The basic composition of Nanjing Pege’s Gravimetric Loss-in-Weight feeder can be divided into two parts: Mechanical system and Control System.

1. The mechanical system is mainly composed of a measuring hopper, a screw feeder, a mixing & feeding motor, and a weighing rack.
2. The control part is mainly composed of load cell, signal amplifier, input / output interface, and control instrument (screen).

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.
