Multotec supplies spiral test units for both heavy minerals and coal applications. Heavy minerals pilot plants comprise 4 stages of spirals, and are capable of processing up to 20 tons of dry solids per hour in the feed to the spirals. The coal test units consists of double stage MX7 or SX7 spirals, and are capable of processing 36 tons of coal per hour to the spirals.
For heavy minerals spiral test units desliming and dewatering cyclones are included, with concentrate and tailings stacker cyclones being optional. A four-stage spiral circuit – Rougher, Cleaner, Re-cleaner and Scavenger – is used and spirals are interchangeable depending on the mineral being treated.
MX7 or SX7 spirals are used for coal spiral test units and are interchangeable depending on the operation layout.
