coal spiral concentrator XSM is a leading global manufacturer of crushing and milling equipment (coal spiral concentrator),XSM also supply individual (coal spiral concentrator...) crushers and mills as well as spare parts of them.

Spiral concentrators, like cone concentrators, are efficient, low-maintenance units that should be considered for any large- scale gravity separation system. The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns).

Compound spirals offer better performance in a more efficient configuration. Prep plant operators in the US are increasingly opting to use spiral concentrators. They are easy to install, operate and maintain but their downfall is low capacity. The article describes spirals available from PrepTech

Wet Spiral Separators. Spiral separators of the wet type, also called spiral concentrators, are devices to separate solid components in a slurry, based upon a combination of the solid particle density as well as the particle's hydrodynamic properties (e.g. drag).
