Abstract: Energy resources of China are characterized by rich coal, poor oil and less gas. The stage of economic development
determines that coal is still the main energy source of China. Washing process is a very important step in the field of coal deep
processing, which can effectively improve the utilization and value of coal. The optimization and transformation of Tongxin Coal
Preparation Plant is gradually moving towards achieving high automation and intelligence in production. Under the premise of
reducing infrastructure costs, it saves more expenses and land to optimize and upgrade the washing process, improves the efficiency
of washing, and enhances the competitiveness of the coal preparation plant in the coal market. In order to improve the
economic efficiency of coal and enhance the ability to respond to the market, Tongxin Coal Preparation Plant added a dense
medium shallow trough workshop to carry out technical transformations on the lump coal system to enhance the flexibility of the
washing process, improve product quality and enhance corporate competitiveness and comprehensiveness profitability.

Key words: coal; washing process; optimization and reformation; dense medium shallow trough workshop
