Theory of Operation

The InLine Spinner works by feeding slurry into the base of the spinning polyurethane bowl. The bowl operates full of slurry that swirls in a vortex – throwing the dense particles into the riffles located on the bowl’s inside face. Cutter bars, operating parallel to the inner face of the bowel, create a turbulent zone that beneficiaries recover by allowing heavy particles to replace lighter particles caught in the g-force of the unit. The riffle depth is designed in such a way that the replacement or separation zone almost reaches the root (rear wall) or the riffle. In this way the maximum amount of heavy mineral is recovered and minimal gangue is recovered to the concentrate.

Automation system

This simple robust PLC circuit carries out all unit functions allowing hands free operation. The InLine Spinner 30 second dump cycle compares with a 2 minute dump cycle typical of other BCC technology. The key benefits of the fast dump cycle are more uptime and the opportunity for more frequent dump cycles.
