Definition and Structural Features of a Tube Mill

Tube mills are important fine grinding equipment in modern industry. Their core feature is a cylindrical structure with an aspect ratio of 2-7. They are available in single-chamber and multi-chamber configurations. Multi-chamber tube mills are divided into grinding zones by partitions. The first chamber uses large-sized grinding media to crush the material, while subsequent chambers use smaller media for fine grinding. The material is then screened and discharged via a grate. A typical structure includes a cylinder, feed section, drive system, and sliding bearing support. A stepped liner design improves grinding efficiency.

Core Technology Advantages
High-Fineness Processing Capacity: Materials undergo thorough grinding within the long cylinder, resulting in a uniform product fineness and large specific surface area, making it particularly suitable for the production of high-grade materials such as cement clinker.

Capacity Upgrade Design: Compared to traditional ball mills, tube mills of the same specification can increase output by 30%-50%. The φ4.2×13m model boasts a single unit capacity of 350t/h.

Multi-Scenario Adaptability: By adjusting the grinding media gradation and loading capacity, it can meet both dry and wet grinding needs, supporting the processing of specialized materials such as slag and steel slag.

Main Applications
Cement Industry: Core applications include raw meal preparation, clinker grinding, and slag fine powder production. It is standard equipment for 5,000t/d cement production lines.
Metallurgy and Chemical Industry: Processes blast furnace slag and non-ferrous metal fines, playing a key role in the production of refractory materials.
Power and Building Materials: Applications include fly ash processing and glass raw material preparation. The φ2.4×13m model is commonly used in slag fine powder production lines.
