Atlas Copco continues to expand its blasthole product offering with the addition of the reverse circulation (RC) kit for the DM45/50 mid-range blasthole drill. Based off proven systems, components and technology, the RC kit is designed to meet the demands of today’s expanding mining market by offering the added dimension of in-pit grade control.
A number of components are included with the optional kit, which can also be retrofitted on drills currently in the field. The cyclone arm allows for sampling from the ground or platform level, with a vertical raise and lowering function. A cyclone rotation of 160 degrees provides safe access for cleaning, maintenance and attaching new sample hoses from ground level.
The cyclone is a heavy duty system designed specifically with flexibility in mind. Some of the features of the cyclone assembly are: a hydraulic upper knife valve and pneumatic lower knife valve for collecting and isolating the sample; a hydraulic hinge between the dump box and cone splitter that allows for easy cleaning; and a fixed cone splitter with primary and duplicate sample chutes. All cyclone and sample functions are easily controlled from the operator’s cab.
