Harsh natural conditions make mining at the Raglan nickel project a challenge. Underground operations takes place in permafrost conditions where the ambient air temperature remains below 0 oC. Brine solutions are used for drilling to keep the water from freezing.

Team Mixing engineered a semi-portable slurry plant for testing the viability of using cemented rockfill at Raglan. The plant incorporates a galvanized colloidal mixer, complete with temperature sensors, to accommodate the brine solution.

A bulk bag unloaded, with an integral dust collection system, supplies the plant with cement. The cement holding hopper incorporates an internal spreader and discharge screw. Plant valve control and bin aeration is conducted with the on-board compressed air system (with dessicant type drier).

The PLC control system & touchscreen features multiple recipe selection, alarming and data logging for each batch. A radio control system allows the scooptram operator to call a slurry batch remotely.

The entire plant is designed in modular components with protective roll cages for relocation underground as needed. Quick connect electrical plugs allow for rapid assembly and dis-assembly.
