Coal preparation process selection for Chahasu coal preparation plant

The analysis of raw coal indicate that,the gangue in raw coal may already degrade in water.The little slime in raw coal,the better shatter strength.The size composition of raw coal is rather changeable and is affected by numerous factors,so the capacity of lump coal process system should be large enough.The raw coal is easy to prepare,so should select simple preparation method,such as high density gangue exhaust process.Given the raw coal properties and characteristics of various coal preparation methods,adopt dense medium preparation method for Chahasu coal preparation plant.The equipments selection also follows the relevant principle.The production capacity is designed to 15 Mt/a for completion at once.Analyse the process layout for inside and outside main workshop,further indicate the design is reasonable and low energy consumption.
