A mineral processing company offering industrial mineral solutions for all over the world are using Pinch Valves from AKO within their bulk bag filling systems across various different sites in the UK.
1mm-6mm sized abrasive mineral particles pass through the Pinch Valves at ambient outside temperature. The minerals are free-flowing with gravity pressure. Installed under the product hopper, the Pinch Valve is normally open and performs approximately 80+ cycles per day. 80psi / 5.5 BAR compressed air pressure is used to close the Pinch Valve.
