Coal preparation plant - Wikipedia

A coal preparation plant (CPP; also known as a coal handling and preparation plant (CHPP), coal handling plant, prep plant, tipple or wash plant) is a facility that washes coal of soil and rock, crushes it into graded sized chunks (sorting), stockpiles grades preparing it for transport to market, and more often than not, also loads coal into rail cars, barges, or ships.

Heavy Media Separation Process (ferrosilicon) DMS Powders

Dense Medium Separation utilises a fine suspension of solids within an aqueous carrier fluid to create a medium of intermediate density, relative to the process feed. Particles more dense than the medium will report the process underflow as sinks, conversely less dense particles will report to the process overflow as floats.

Dense Medium Cyclone Principles - Portaclone modular

The medium density at which the separation between more dense and less dense material occurs is called the cut point density. Invariably, there often is a percentage of the feed coal distribution which gets trapped in an envelope of zero velocity inside the cyclone where the centrifugal force equals the drag force. Such material has an equal
