Pulverized coal filter

In the bustling symphony of industry, the transportation of pulverized coal is a crucial note in fields such as metallurgy and petrochemicals. However, this note is not always harmonious, as impurities mixed in the coal powder, such as coarse particles, woven fibers, and wood chips, act like jarring noises, constantly affecting the continuity and safety of the production line. How can this note regain its harmony? This is where our coal powder filter comes into play.

The coal powder filter, though seemingly inconspicuous, holds a pivotal position. It is not only compact in size but also showcases ingenious design wisdom. It is cleverly installed after the air supplement regulator of the total coal injection pipeline at the outlet of the injection tank, acting like a guardian to ensure the smooth flow of the coal powder transportation pipeline.

Its core component is the wear-resistant filter plate, which functions like an experienced doctor using its specialized "scalpel"—the filter plate—to precisely separate impurities from the coal powder. This ensures an unobstructed process during the pneumatic transportation of coal powder, guaranteeing the continuity and stability of the production line.

In terms of construction, the coal powder filter is made of carbon steel, with an inner wear-resistant layer that enhances the durability of the equipment. The double-cone butt-welded structural design creates a stable airflow angle inside the entire shell, allowing coal powder to pass through more smoothly, reducing resistance and minimizing wear. The central wear-resistant manganese steel filter plate, with its excellent wear resistance and filtration efficiency, effectively filters out impurities from the coal powder.


This filter plate is designed to be removable and installable, not only facilitating maintenance and replacement but also significantly reducing equipment downtime and maintenance costs. It is like a beautiful symphony—despite interference from noise, harmonious melodies can still be played through clever design and efficient maintenance.

The design principle of the coal powder filter is simple yet highly effective. It is like an experienced craftsman who, with simple tools, can create exquisite works. In industrial applications, it is widely used in blast furnace coal injection systems, becoming a key equipment to ensure the continuous and stable operation of the coal injection system.

In summary, the coal powder filter effectively filters impurities from coal powder through a simple filtration principle. It not only improves production efficiency and extends equipment lifespan but also reduces maintenance costs. It is a reliable assistant in industrial production, providing strong support for the production of metallurgy, petrochemicals, and other industries. In this bustling symphony of industry, the coal powder filter is one of the most melodious notes.
