The 2.1 × 4.5 steel slag rod mill is a fine grinding equipment specifically designed for processing steel slag, ore, and other hard materials.  It features a cylinder diameter of 2.1 meters and a length of 4.5 meters, making it suitable for metallurgical, building materials, and environmental recycling industries. The equipment uses steel rods inside the cylinder to impact and grind the material, achieving uniform particle size and controllable fineness, making it particularly suitable for processes such as steel slag micropowder preparation.

This model of rod mill is typically equipped with a main motor with a power of 380 to 450 kilowatts, ensuring efficient and stable grinding performance during continuous operation. Its processing capacity depends on the hardness of the raw material and the feed particle size, generally ranging from 15 to 35 tons of steel slag per hour. The equipment utilizes a heavy-duty bearing support structure and an optimized transmission system to effectively reduce vibration and energy consumption, extending its service life. Furthermore, the cylinder lining is made of high wear-resistant alloy material, reducing maintenance frequency and improving operational efficiency.

The control system is typically a centralized electrical control system, supporting remote monitoring and automated operation, facilitating integration into large-scale production lines. Depending on the configuration (such as whether a reducer is included, the type of lubrication system, and the grade of electrical components), the ex-factory price of the complete machine usually ranges from US$120,000 to US$180,000. Including installation guidance, transportation, and basic supporting services, the total cost may approach US$200,000.

Overall, the 2.1 × 4.5 steel slag rod mill, with its reasonable structural design, reliable operating performance, and moderate investment cost, has become one of the mainstream choices in steel slag resource utilization projects. In the context of emphasizing environmental protection and the circular economy, its application prospects continue to expand.
