Multotec has designed and optimised the double stage MX7 coal spiral concentrators to process feed with a size range of 2.0 mm to 0.1 mm for difficult-to-wash coal. The 2-stage spirals, the SX7 and MX7, incorporate two stages of spiralling into a single spiral assembly, reducing plant height and floor space requirements – ultimately reducing capital and operating costs.
These coal spiral concentrators are constructed with materials that ensure a high quality product with a longer life, lower maintenance requirements and reduced costs. To add flexibility when building or replacing the spiral plant, it has a compact modular design.
