Feed Hoppers – Heavy-Duty Machines Designed For Vast Range Of Applications

By Steven Harrisson, October 31, 2014

The feed hopper is a machine used for receiving, storing and conveying different types of materials. In general, there are two types of feed hoppers: dry and wet feed hoppers. Depending on the material that is used, the feed hopper can be either dry or wet. The dry feed hopper is commonly used, because the manufacturing process creates dry products with high level of clods and dirt. The storage and conveying capacity of the feed hoppers varies from 1 up to 20 tonnes per hour.


The feed hopper is designed to load and unload bulk materials from a dump truck directly. It uses a slow out-feed belt to create forward movements towards the out-feet end. The rate of slow out-feed ensures a continuous flow to the rest of the processing line. A typical feed hopper features:

  • Heavy-duty construction with a roller chain bed and a heavy-duty conveyor fixed to the bed;
  • Out-feed moderator for even-out and out-feed speed;
  • A speed drive to control the conveyor speed;
  • Easy access for service and maintenance;

These heavy-duty machines are designed for a vast range of applications. With a wide choice of wet and dry models, each operator can choose a feed hopper according to its needs. The main parts of a typical feed hopper are: a heavy-duty conveyor chain, and a bed covered with a heavy-duty rubber belt. The slope of the hopper can be adjusted, and it needs to be adapted to the line before every operation. Also, the height at the discharge end must be set to the correct height for unloading materials or products on trucks or bin tippers.

The newer feed hopper models come with electrical controls which automatically adjust the speed of the conveyor and the height at the discharge end. Thus, the “dead time” between changeovers is minimized and the efficiency of the operation is increased. The newer feed hoppers also come with easily removable and replaceable health and safety guards. They ensure reduced maintenance time and increased plant running time.

In the key areas, the feed hoppers have rubber lining for maximum wearing out resistance, increased durability and reduced repair and maintenance costs. The integrated belt mechanism provides an extremely efficient transfer of materials to the discharge end, increasing in this way the productivity. Some feed hopper models are equipped with modular sections for increased capacity. These hoppers ensure greater flexibility and operation efficiency.
