Screening – RCR Mining Technologies


RCR MT has a variety of custom vibrating grizzlies and screens, which particularly suit our mobile product range.

Rotating Trommel

RCR MT has a proven track record in providing high capacity, low maintenance trommels to major mineral sands miners with extreme screening and material demands. RCR MT utilises proven tyre or trunnion drive systems and has adopted many maintenance friendly techniques to ensure that the trommels provide maximum availability to the operation.

RCR MT has developed an efficient computer design model for throughput calculations and can customise for each material application.
