Coal washing is a process that is undertaken in a coal washery or coal preparation plant (CPP) where coal is refined or cleaned of impurities. Coal washing involves using water, mechanical techniques and relies on gravity and the difference of density between coal and it''s impurities which are usually more densely packed due to the fact that ...
Anglo Coal Australia Ltd. Anglo Coal Australia Ltd owns and operates a number of mines in Queensland and New South Wales.. Callide mine. Callide mine is a leading Queensland domestic coal producer providing lowsulphur, subbituminous thermal coal primarily for domestic power generation. The coalfields cover an area of 180 square kilometres and contain seams up to 26 metres thick.
Coal needs to be stored at various stages of the preparation process, and conveyed around the CPP facilities. Coal handling is part of the larger field of bulk material handling, and is a complex and vital part of the CPP.. Stockpiles provide surge capacity to various parts of the CPP. ROM coal is delivered with large variations in production rate of tonnes per hour (tph).

The allflux® fluidised bed separator combines high throughputs as well as high efficiency levels while cleaning, upgrading, thickening and blending within one single machine. allflux® technology is used for producing highquality concrete sand, coal .
A fluidized bed dryer was selected and adapted to intercept and dry coal flow to one pulverizer. This demonstration proved successful, and the decision was made to fully retrofit both 600MW units with Great River Energy''s DryFining fuel enhancement process.
Densified coal resulting from the Coldry Process is regarded as a black coal equivalent or replacement for black coal. The Coldry Process is a patented coal upgrading technology being developed in Victoria, Australia by Environmental Clean Technologies Limited based on ''brown coal densification''.
As a result, the temperature of the drying agent and the residence time of the particles have to be selected according to the coal type, so that no ignition will occur, the volatile matter loss to be low, but the drying process still be efficient. It is well known that in a fluidized bed, with a temperature rise,
