Metso's Mining and Construction Technology
Metso's McNally Visman Tricone has the ability to clean fine coal without dense media and with no moving parts. It is a gravimetric separation cyclone in the hydrocyclone category.
It can be employed as a cleaning device upstream of other washing equipment to process fines. A variety of vortex finders and apex nozzles are available, depending upon the particular requirements of the application.
Three sizes of Tricone are offered: 8", 12" and 24" diameter. Coal slurries with feed sizes from 28M x 0 to 1-1/4" x 0 and capacities from 130 GPM to 1820 GPM are typically processed in a single Tricone.
