Rotoflo is designed to help with material handling ensuring that silo discharge is free-flowing and controlled when handling a number of diverse materials. The system is designed to help prevent powder bridging and ratholing in silos and hoppers.

"Rotoflo is the best silo discharger! Multiple outlets, no aeration, no vibration and runs almost maintenance free."
Silos are generally used for the storage and discharge of powdered or granular bulk solids; a silo discharge system is designed to aid in the discharge of materials quickly and efficiently, thereby eliminating the risk of powder bridging, ratholing or blockage.
Rotoflo silo discharge units can be built-in or retrofitted to existing vessels and, as such, will allow materials to be safely and efficiently discharged from a silo or hopper. With multiple configurable outlets, a Rotoflo silo discharge unit can both reduce the risk of material flow problems within a vessel, and provide a controlled rate of discharge to multiple downstream processes.
Powder bridging occurs when materials in a silo or hopper become interlocked, thereby forming a stable arch over the designated outlet. When powder bridging occurs, materials stored in the silo become trapped. Silos should be fitted with an appropriate discharge aid to avoid this and ensure correct and efficient discharge.
Ratholing is the formation of a stable column of material on the side walls of the silo or hopper. Generally, as a result of unsuitable hopper geometry, in these cases the product will only flow through a channel at the centre of the storage vessel; the rest of the product will stay on the sides. This significantly reduces the live storage capacity of the silo.
