The Concept

We offer horizontal and inclined Belt Feeders for extracting bulk materials from under a dump hopper or regulating feed to a crusher or screen.  Belt Feeders can provide volumetric feed and even metering to prevent flooding.

A Belt Feeder consists of the following parts:

  • A fabric reinforced belt or a steel cable reinforced belt that carries the material. 
  • The belt is propelled by a Drive Pulley and Shaft
  • The drive shaft are rotated by a Drive Mechanism. 
  • A Tail Shaft and a Screw or Hydraulic Tensioning Mechanism
  • All these parts are mounted to a robust Steel Main frame.
  • Auxiliary equipment may include a feed chute, skirtboard, a discharge chute and a High Pressure Lubrication System

 

Superior Chutework Design

It all starts with the design.  Discrete Element Modeling (DEM) helps the designer predict how the material will flow through the chutework and determine how the material will affect the life of the wear liners and the belt.

Drive Types

Several types of drive systems are available depending on the application, preference and cost.

All include an electric motor, a reduction mechanism and often a speed adjusting device.

Hydraulic Drives

Hagglunds provides a Low Speed High Torque hydraulic drive that is very common for belt feeder applications.  Their robust design, variable speed and ability to provide full starting torque for an unlimited time provide advantages in this high-load application.  Above all, Hägglunds drives have a unique capacity to handle the starts, stops and heavy shockloads common to feeder operation.

 

 

An alternate type of hydraulic drive is based on a conventional electric motor and gear reducer.  A separate hydraulic motor (driven by the reducer) is required to control the speed.
