An analysis of medium losses in coal washing plants

The sieve bends and the first section of each drain-and-rinse screen are used to drain medium from the coal; the medium is collected in screen under-pans and returned to the primary cyclone sump via the primary cyclone medium distribution box. The second section of the screens is used to rinse and drain the coal free of adhering medium.

Improved Performance of Banana Screens in Drain and Rinse

The objective of this project is the identification of the factors controlling the efficiency of the high capacity Banana screens when they are used to recover media via drain and rinse. This includes potential approaches to improve efficiency with respect to fluid recovery, partition curves and magnetite recovery.

Regular Inspections Prevent Magnetite Losses Coal Age

Drain-and-rinse screens play a pivotal role in magnetite recovery in heavy-media prep plants. They use a set of water sprays to wash the coarse coal as it passes across the screening media. A wet-drum magnetic separator is then used to recover the magnetite from the slurry that flows from the drain-and-rinse screens.

Wes Mackinnon and Andrew Swanson, QCC Resources Pty Ltd

A modern Australian coal preparation plant typically consists of wet screening, dense medium high‑frequency vibrating screens are often used for the dewatering of sand‑sized fine reject and, in some that have one desliming screen, two drain and rinse screens (product and reject) and a single dense medium cyclone.

Coal preparation plant . 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.

Magnetite Recovery in Coal Washing by High Gradient

Sharp separations have been achieved by reducing the top size of the feed to the cyclone. Such recent advances in the cleaning of finer sizes of coal required that entire coal-magnetite streams, which are normally run over drain and rinse screens for separation of a large portion of the magnetite, be fed directly to magnetic separators.
