The 2145 dry ball mill is a large dry ball mill with a barrel diameter of 2.1 meters and a barrel length of 4.5 meters. It is widely used in concentrating plants for metal ores such as iron, copper, and gold, as well as non-metallic ores such as fluorite and quartz. Before purchasing a dry ball mill, it is important to fully understand the equipment parameters to determine whether it is suitable for your application. This article will introduce the parameters, processing capacity, and ball loading ratio of the 2145 dry ball mill.

Detailed Explanation of the Main Parameters of the 2145 Dry Ball Mill

1. Main Structure and Operating Principle

The 2145 dry ball mill consists of a feed unit, a grinding body, a discharge unit, a motor, and a control system. Its operating principle is to use the grinding body to grind, grind, and mix the material, thereby refining the material particles and improving its reaction performance.

2. Dimensions and Weight

The 2145 dry-type ball mill has dimensions of 2145 mm in length, 1545 mm in width, and 1820 mm in height, and weighs approximately 20 tons. These dimensions and weight ensure the dry-type ball mill is more stable and reliable during production.

3. Grinding Mill Electronic Control System

The 2145 dry-type ball mill utilizes a PLC automatic control system, enabling automated production process control. The electronic control system monitors and adjusts the mill's operating status to ensure safe and stable operation.

4. Application and Applicable Materials

The 2145 dry-type ball mill is suitable for grinding, mixing, and refining materials in the mining, metallurgy, building materials, and chemical industries. Applicable materials include ore, limestone, cement, and quartz sand.

5. Safety Devices

The 2145 dry-type ball mill is equipped with a variety of safety devices, including motor overload protection, spindle speed protection, and feed overload protection. These devices effectively ensure safe operation of the mill.

6. Maintenance and Care
The 2145 dry-type ball mill requires regular maintenance and care during operation, including cleaning, lubrication, and bolt tightening. Regular maintenance and care can extend the dry-type ball mill's service life and improve production efficiency.

7. Processing Capacity
The 2145 dry-type ball mill has a maximum processing capacity of 15-25 tons/hour. This means it can process a large amount of material per unit time, making it suitable for the production needs of small and medium-sized production lines.

8. Grinding Media and Specific Gravity
The 2145 dry-type ball mill uses steel balls with a diameter of 30-50 mm as its grinding media. The selection and proper use of grinding media have a significant impact on the grinding effect and lifespan of the dry-type ball mill. During operation, the specific gravity of the steel balls is generally 4-6 times that of the media.

9. Motor Power and Speed
The 2145 dry-type ball mill has a motor power of 95 kW and a speed of 24 rpm. The motor is the key power source for a dry-type ball mill. The motor power and speed should be selected based on the material characteristics and production requirements to ensure proper operation.

10. Grinding Machine Parameters

The 2145 dry-type ball mill has a speed of 21.7 rpm, a grinding media load of 22 tons, and a grinding media load of 8 tons. These parameters have a significant impact on the grinding effect and processing capacity of the dry-type ball mill.

The daily processing capacity of a dry-type ball mill should be equal to the tonnage of ore processed daily by the concentrator. The processing capacity of the 2145 dry-type ball mill is listed in the parameter table above. If we assume the dry-type ball mill operates 10 hours per day, the daily processing capacity of the 2145 dry-type ball mill is approximately 1,000 tons. Therefore, if your concentrator plans to process around 1,000 tons of ore per day, the 2145 dry-type ball mill is a solid choice!
