18x7m ball mill parameters

The 18x7m ball mill is a large-scale grinding equipment that is commonly used in mineral processing plants. It has a cylinder diameter of 18 meters and a cylinder length of 7 meters. The following are the main parameters of this ball mill:

1. Motor power: The motor power of the 18x7m ball mill is 7100KW, which is the power of the main motor.

2. Rotational speed: The rotational speed of the ball mill cylinder is 14.5r/min. The speed of the ball mill is an important parameter that affects the grinding efficiency of the equipment. It is usually determined by the diameter of the ball mill and the material properties.

3. Grinding media: The grinding media used in the 18x7m ball mill is high-chromium cast iron grinding balls. The diameter of the grinding balls is 125mm. The grinding balls are the medium used for grinding the ore inside the ball mill, and their size and material are also important factors that affect the grinding efficiency.

4. Production capacity: The production capacity of the 18x7m ball mill is 100-120t/h, which means that the maximum amount of ore that can be ground in one hour is 120 tons.

5. Feed particle size: The maximum feed particle size of the 18x7m ball mill is 25mm. The particle size of the feed material is an important factor that affects the grinding efficiency of the ball mill.

6. Discharge particle size: The discharge particle size of the ball mill is determined by the size of the screen installed at the discharge end of the mill. The size of the screen used in the 18x7m ball mill is 3mm.

In summary, the 18x7m ball mill is a large-scale grinding equipment used in mineral processing plants. It has a high motor power and production capacity, and its grinding media, rotational speed, feed particle size, and discharge particle size are all important parameters that affect the grinding efficiency of the equipment.
