Coal Powder Preparation
Processed coal and petroleum coke powder have high combustion efficiency and are more effective as solid fuels. Depending on the specific processing technology, flexible operations can be carried out during production. Coal, when used as fuel, is generally processed to a fineness of 200 mesh D80-D90, petroleum coke is generally processed to a fineness of around 200 mesh D90-D95, and calcined petroleum coke is generally processed to a fineness of 200 mesh D60-D75. Traditional methods for producing such coal powder and petroleum coke typically involve the use of equipment such as Raymond mills and ball mills. With the increasing emphasis on energy saving and emission reduction across society, after years of practice, Dawn Heavy Industries has dedicated itself to developing a complete set of powder milling equipment specifically for coal powder processing and petroleum coke powder preparation-the LM Vertical Coal Mill (Medium-speed Coal Mill) process. Users can make diversified choices according to their requirements for output, investment, etc.

The LM series vertical coal mill, abbreviated as medium-speed coal mill or vertical coal mill, serves as the core of the project. It integrates crushing, drying, grinding, and grading, along with conveying, into one system. It achieves the powder-making process in a "one-step method" by simultaneously grinding and drying in the form of combined drying and powder making. This large-scale powder grinding equipment embodies stable technological elements, equipped with CO-O2 online analysis system, roller hydraulic device, and automatic control system, making the entire powder-making process intelligent, convenient, energy-saving, and environmentally friendly.
Scope of Application
Suitable for users with large demands for coal powder and petroleum coke powder production. The processing range for preparing coal powder and petroleum coke powder is from 4 to 100 tons per hour.The LM series vertical coal mill, abbreviated as medium-speed coal mill or vertical coal mill, serves as the core of the project.
