How to optimize mass flow with Matcon’s cone valve IBC

Matcon manufactures the unique cone valve IBC.

Firing Industries Ltd. is Canada’s source of Matcon processing equipment, including its revolutionary Intermediate Bulk Containers (IBCs). One area in which Matcon products excel is mass flow. According to industry experts, that mass flow is the preferred discharge pattern for powder processing, as it keeps mixed materials consistent throughout the production process. The best way to achieve this is through the Matcon cone valve IBC, which has a geometry designed to create that flow.

The opposite of core flow

Mass flow is the movement of all powder across the entire container whenever any is withdrawn; it produces a first-in/first-out flow sequence, which eliminates all stagnant areas and provides a steady discharge with consistent bulk density, as well as a uniform, controlled flow. Matcon achieves this by implementing effective design solutions in the internal surface friction of the hopper, the hopper’s angle, and the valve type.

This is the opposite of core flow, in which powder flows mainly from the centre of the container, above the outlet, during discharge. This leaves material on the sides and causes particle rolling and mix separation, making it difficult to get the material out of the IBC. This is a common disadvantage of IBCs that use butterfly valves. Other drawbacks include long-term container damage, production downtime, and continued inconsistencies in the recipes. Firing Industries helps powder-processing businesses overcome this with the Matcon cone valve IBC.

This IBC has an innovative cone-shaped design that raises and lowers the valve at the discharge outlet. It accounts for bridging, arching, and core flow – while assisting mass flow – partly with internal vibration of the cone as it lifts. Consistent product flow yields production lines that run continuously and automated discharge processes.

The Matcon cone valve IBC integrates vibration right into the cone at the top of the lifting cycle, which stimulates even the most stubborn powders to flow downwards and reduces the potential for bridging. If the powder flows freely, the cone’s lift can be reduced to control the quantity of flow at discharge.
