Abstract: According to the demand of the coal market, the water washing and gangue separation equipment and screening
equipment in the coal preparation plant are out of service, resulting in complex operation of the overall process and increased
operation and maintenance. In order to solve the above problems, the original coal handling system was transformed and the raw
coal secondary crushing system was added. After completing the transformation of the project, the implementation quality and
management level of science and technology projects can be improved to achieve the purpose of reducing personnel though
science and technology, improving quality and efficiency of the company.

Key words: coal preparation plant; coal handling system; simplified transformation; secondary crushing system of raw coal;
