Ajax Equipment, Bolton, UK, has supplied leading black masterbatch producer Hubron International with a system to handle bulk bags and supply a new extruding line with carbon black. The handling system consists of a screw feeder with Lynflow ribbon flights, hopper featuring Lynflow insert and accommodates the site’s bulk bag discharger together with a support beam structure for hoist lifting of bags. The solids handling system supplied is similar to equipment Ajax had previously manufactured for Hubron.

The single span screw effectively transfers the non-free flowing carbon black to top up a hopper with progressively steepening geometry and includes a Lynflow insert which helps promote reliable flow despite low wall angles. The reed insert vibrates to disturb the material effectively without rattling the hopper. The insert modifies the flow pattern inside the hopper, improving movement of material towards the screw. The hopper construction therefore ensures the extruder has a consistent supply of material.   

Ajax Equipment managing director Eddie McGee commented: “Carbon black is a poor flowing material which can provide challenges when headroom is tight and elevation is required on transfer equipment. The Ajax system supplied to Hubron draws on our extensive experience as well as our powder testing techniques to provide a reliable design ensuring smooth and steady flow to onward process. Ajax worked collaboratively with Hubron who wanted to reuse a hoist and a big bag discharger as time was short for executing the contract.” www.ajax.co.uk
