Coal resources are a fundamental energy source in our country, with a substantial consumption volume.Horizontal Coal MillA machine that crushes coal lumps into powder, it is an important auxiliary equipment for coal powder furnaces. The process involves the coal being crushed and its specific surface area continuously increasing. To increase the surface area, it is necessary to overcome the intermolecular forces of the solid, as energy is required. The coal is ground into powder in the coal mill primarily through three methods: crushing, smashing, and grinding.

Coal Mill Classification

Coal grinders are categorized into three types: low-speed, medium-speed, and high-speed models. Each type has its own advantages, and customers can select the appropriate coal grinder for production based on their actual needs.

Process Introduction

Raw coal is fed into the feed device of the mill, with a temperature ofAt approximately 300℃ hot air also enters the feeding unit through an air intake duct. Inside the drying chamber, there are specially designed lifting plates that lift the raw coal, facilitating intense heat exchange and drying. The dried coal pieces then pass through a double-layer baffle with lifting plates into the pulverizing chamber. The pulverizing chamber is equipped with grinding media (steel balls), where the coal pieces are crushed and milled into coal powder. Simultaneously with the crushing of the coal pieces, a dedicated blower extracts the milled coal powder and gas through the mill's discharge unit. Coarser particles are returned to the pulverizing chamber via the discharge unit's return screw for further grinding.

Currently, there are numerous manufacturers producing coal grinding machines domestically, with the older and more established one being Xinxiang Great Wall. Xinxiang Great Wall has...60 years of coal mill production experience, over these 60 years of trials and tribulations, Xinxiang Great Wall has accumulated abundant coal mill production experience. Our coal mills are structurally rational, with high powder grinding efficiency, strong adaptability to materials, high output, and are ideal for coal powder preparation.
