Until now, minus 325 mesh (44µm) particles were typically recirculated or sent to refuse. Our Sub325™ fine coal recovery system can now capture this particle size, delivering it to your clean coal belt at less than 20% moisture. The combination of exceptionally high G-force, internal geometry and rotational differential in our centrifuge unlocks this new source of revenue by putting this size fraction on the clean side of your plant.
In a recent four-month trial in a prep plant with a raw feed of 500 tons (454 tonnes) per hour, our Sub325 system functioned at an average production rate of 14.1 tons per hour (12.8 tonnes/hr), producing 7,500 tons (6,804 tonnes) of sub-20% moisture ultra-fine coal. Over the course of the trial, we were able to positively validate performance.
The Sub325 system unit fits into your existing prep plant processes. Inserted onto the recirculation feed after the screenbowl, Sub325 system captures even more ultra-fine clean coal.
