System and method for unloading bulk powder from large bulk containers

A bulk unloading system for unloading a bulk powder comprising:

• (a) a bulk container removably mounted on a platform, the container having surrounding walls and a floor mounted on a structural frame and two ends, a front end and a rear end, wherein the front end is closed and the rear end is at least partially open;
• and the platform having a means of tilting the container at an angle from about 0 to at least 40 degrees;
• and
• (b) a manifold having inlet and discharge sections, the manifold being mounted by a support member connecting to a location selected from the group consisting of the rear end of the container and the platform to connect the inlet of the manifold to the rear end of the container, wherein at least a portion of the manifold is lined with a pneumatic conditioning membrane and wherein on the manifold is a service port by which gas service is supplied to the pneumatic conditioning membrane in order to enhance the flow of the bulk powder in the manifold;
• wherein the system is capable of unloading a bulk cohesive powder having Geldart classification type C behavior.
