Spirals

Heavy Mineral Spirals

Separation of fine heavy minerals has been made easier with Multotec’s ranges of mineral spiral concentrators from 1.5 mm to 0.1 mm which are ideal for iron ore, chrome, mineral sands and high-density ores.  

Available in the HX3, HX5 and SC ranges, the modular housing frames house two spiral assemblies and have a number of optional features that can be fully dismantled for retrofitting. Componentry includes the spiral trough, auxiliary or sliding splitters, launders, distributors and piping, feed box and product box with product splitters, all with salient features to provide longer life, increased production and ease of repair, and reduced downtime. 

Coal Spirals

Multotec has developed both single (SX4) and double (SX7 and MX7) devices and optimized them to suit coal concentrators. Our coal spirals can be assembled in single, double or triple starts as well as up to seven turn configurations in high or low feed ash profiles. They are developed for coarse coal qualities and are guaranteed to improve overall separation efficiency. 

New research and development have shown that our compact, modular designs have added flexibility when building or replacing spiral plants, resulting in processing solutions that extend the life of your plant and reduce overall maintenance costs.

Our product range includes:  spiral bank, slurry distributors, pipe launders
