Metal heap loading operations. Processes where a Sepro Agglomeration Drum can be utilized include gold, copper, uranium and nickel laterite. The action in the agglomeration drum, combined with small additions of cement or lime, binds the fines into a "pelletised" product, which can be heaped and leached out without "pooling" and "channeling" caused by loss of heap permeability due to blinding by fines. The machine uses flexible rubber liners to prevent build up without the use of lifter bars and is adjustable on a pivotable base frame. Shell supported agglomerators such as the Sepro PTD Agglomeration Drum minimize stress on the shell by spreading the power drive over the full length of the unit. Sepro Tyre Drive Grinding Mills Sepro Tyre Driven Grinding Mills are designed for small and medium capacity grinding applications, specifically small tonnage plants, regrinding mills, reagent prep and lime slaking. Sepro Pneumatic Tyre Driven (PTD) mills provide an alternative to standard trunnion drive systems. The drive consists of multiple gears boxes and electric motors directly connected and controlled through an AC variable frequency drive. Shell supported mills such as the Sepro PTD mills minimize stress on the mill shell by spreading the power drive over the full length of the mill. Sepro Mills are suitable for ball, rod and pebble charges and are available with overflow or grate discharge to suit the application. Shell supported mills such as the Sepro PTD Grinding Mills minimize stress on the shell by spreading the power drive over the full length of the unit. Condor Dense Medium Separators The Condor Dense Medium Separator (DMS) is a multi-stage, high efficiency media separation machine for mineral processing operations at the rougher and scavenger stage. It is typically used in a pre-concentration duty prior to processing or milling to reject barren material. The unit is manufactured with either two or three stages of separation depending on the media with one or two valuable densities resulting, while the unit can produce up to four products from one dense medium vessel altogether. The Condor DMS can take a larger feed particle size compared to a DMS cyclone of the same diameter and capacity, and is capable of handling higher sinks or floats loading without affecting performance. The valuable dense material (or 'sinks') can be combined or separated at the final stage and is then pumped onto the next process in the circuit. Sepro Mineral Systems
