Figure 1. This hopper’;s simple construction
often makes it the most economical choice.
Figure 2. This design allows greater hopper capacity
at a lower overall height than a conical hopper.
Figure 3. This design saves headroom,
but doesn’;t suit air injection.
Figure 4. This hopper combines the advantages
of a chisel hopper with a circular outlet.
Achieve solid success
Bulk materials are composed of individual particles that can vary in size, shape, surface roughness, moisture content and chemical composition. You cannot extrapolate the behavior of one material to other materials, even those that have similar chemical compositions.
The key to success is knowing a material’;s flow properties and understanding the conditions that affect them. This knowledge, coupled with the ability to easily and accurately interpret the property data, will provide a sound basis for process improvements and equipment design or selection.
