The Northwest region is rich in coal resources, providing sufficient raw material guarantee for coal powder stations. The national environmental protection policy and the Western Development Strategy provide policy support for the development of coal powder stations, and industrial production and winter heating demand also promote the growth of the coal powder market. Under the background of increasingly stringent environmental protection requirements, coal powder stations need to increase environmental protection investment and adopt high-efficiency and low-emission technologies to enhance competitiveness.

This project is a large-scale clean coal powder preparation project in the Northwest region. In the early stage of project planning, the owner actively responded to the national green development and environmental protection concepts and planned to build an efficient and environmentally friendly clean coal powder preparation production line. After comprehensive and rigorous evaluation and multi-scheme comparison analysis, the clean coal powder preparation technology independently developed by Zenith Machinery - LM series vertical coal mill, with its superb comprehensive performance and environmental protection advantages, stood out from many schemes and finally won the high recognition and selection of customers.
