Multotec HX5 spirals continue to gain popularity especially in heavy minerals

first_imgThe HX5 spiral, the result of intensive testing by Multotec Process Equipment, was introduced into the heavy minerals sector a few years ago and is today finding ready acceptance in the market. The high capacity HX5 version of the conventional Multotec heavy minerals spiral can treat up to 5 to 8 t/h of dry solids compared to 1 to 2.3 t/h.“The HX5 has been specifically engineered for chrome and iron ore applications. Its shallower slope and larger 1,000 mm diameter make it suitable for rougher and scavenger applications,” Renira Reddy, product manager: gravity concentration at Multotec, explains. “Fewer units are needed to treat the same feed material because it handles higher capacities.”The spirals are equipped with sliding splitters for simpler adjustment for product collection, resulting in an easier operation. It allows for a larger mass pull to the concentrate and can treat fine ores ranging between 50 µm and 1.50 µml and is particularly effective on the size ranges between 50 µm and 300 µm. The spiral can be fitted with wash water where required.The HX5 can be assembled into a quad, with four assemblies on a centre column, further reducing the footprint resulting in additional cost savings. Ease of erection and the reduced number of units required also lead to a reduction in capex costs.last_img
