Storage Bins and Hoppers for Bulk Materials

Proper design of a bin or hopper is essential for promoting good gravity-flow. Hopper walls should be steep enough to overcome the force of friction between the material and the hopper wall. Flow within the bin or hopper can be assisted by the use of flow aids such as a vibrator or agitator.

Reducing or Eliminating Arching in Hoppers | …

The design of the hopper should not only focus on the movement of powder in and out of the hopper, but also consider its storage in the hopper to avoid arching. A number of studies on hopper angle have led to the conclusion that the most efficient angle for flow is between 45 and 70 degrees.
