(PDF) An analysis of medium losses in coal washing plants

With a view to achieving 16% clean coal ash, the following changes were made in the coal washing plants:(a) The relative density of medium in the primary cyclone circuit was reduced from 1.36 to 1.3-1.33 (b) The spigot diameter of the secondary cyclones was reduced from 140 mm to 125 mm.

Dense Medium Cyclone

From the early 1960’s until the mid 1980’s, dense medium cyclone circuitry design technology did not change appreciably. The basic design, which was both highly flexible and highly efficient, was consistent with technology developed by the Dutch State Mines (“DSM”) in the mid 1940’s. During this period, the “typical” dense medium cyclone circuit was designed to process raw coal

Cone angle of 20 ~. Cyclones typically treat ores and coal in the range 0.5-40 mm. The largest cyclones now exceed 1 m in diameter and are capable of throughputs in coal preparation of over 250 t/h The ore or coal is suspended in the medium and introduced tangentially to the cyclone either via a pump or it is gravity-fed. The dense material is

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.

DENSE MEDIUM CYCLONE OPTIMIZATON (Technical Report)

Three dense-medium cyclone tests were performed using different underflow diameters to produce feed material for the flotation separations. The use of different underflow configurations caused a variation in the pulp and solids splits, which changed the clean-coal yield and the magnetite-to-coal ratio of more » the cyclone products, and hence

A coal dense medium separation process can benefit substantially from process control provided that a dynamic model for this process is available as was previously developed by the authors for a fine coal dense medium cyclone (DMC) circuit. In this paper, the previous model is adapted to a coarse coal DMC
