Comprehensive Review on Coal Preparation Technology

Review is made in the paper on coal preparation development since 1998. It points that, the status of coal preparation development is mainly demonstrated from following aspects: gradually increasing in raw coal washed ratio, the scale of coal preparation plant and coal washing equipment becoming larger in size; the ratio of coal washed by dense medium system rapidly increases and the technology of coal cleaning by use of dense medium cyclone has been developed at high speed; performance of conventional coal cleaning processes and equipment have been improved; rich fruitage regarding development of novel fine coal cleaning equipment have been obtained; modular design has become popularly attensive mode in coal preparation plant construction and automatic control of coal washing process as well as pant full automation have been up to a new level.
