How big a flotation tank should a 300 ton ball mill be equipped with?

Ball mills and flotation cells (flotation machines) are commonly used equipment in the mineral processing process. Choosing the right equipment can not only improve mineral processing efficiency, but also effectively reduce production costs. This article will discuss in detail the matching of 300-ton ball mills and flotation cells to help enterprises optimize mineral processing processes and improve economic benefits.

1. Specifications and processing capacity of ball mills

A 300-ton ball mill refers to a ball mill that can process 300 tons of material in one day. The specifications of a 300-ton ball mill are generally expressed in terms of processing capacity per hour (t/h). For example, the MQGg1830 grate ball mill has a processing capacity of 27t/h, while the MQYg1836 overflow ball mill has a processing capacity of 29t/h.

When choosing a ball mill, in addition to processing capacity, factors such as cylinder diameter, cylinder length, motor power, and ball loading should also be considered. The following are some common ball mill specifications:

MQGg1830: cylinder diameter 1800mm, cylinder length 3000mm, motor power 180KW, ball loading 14t.

MQGg1836: cylinder diameter 1800mm, cylinder length 3600mm, motor power 180KW, ball loading 13.8t.

MQYg1836: cylinder diameter 1800mm, cylinder length 3620mm, motor power 180KW, ball loading 13.8t.

2. Matching principle of flotation cell

The flotation cell is a device used for mineral flotation, and its size directly affects the flotation effect and processing capacity. When selecting a flotation cell, the following factors need to be considered:

a. Processing capacity: The processing capacity of the flotation cell should match the processing capacity of the ball mill. For example, if the processing capacity of the ball mill is 27t/h, the processing capacity of the flotation cell should also be within this range.

b. Slurry concentration: Slurry concentration will affect the flotation effect, and the appropriate flotation cell should be able to maintain an appropriate slurry concentration.

c. Flotation time: Different minerals require different flotation times, and the size of the flotation cell should be able to provide sufficient flotation time.

d. Operational convenience: The flotation cell should be easy to operate and maintain to reduce production costs.

3. Flotation cell selection for 300-ton ball mill

For a 300-ton ball mill, it is crucial to choose a suitable flotation cell. Here are some suggestions:

a. Processing capacity matching: When selecting a flotation cell, make sure that its processing capacity matches that of the ball mill. For example, if the ball mill has a processing capacity of 27t/h, you can choose a flotation cell with a processing capacity between 25-30t/h.

b. Slurry concentration control: The flotation cell should be able to maintain an appropriate slurry concentration to improve the flotation effect. The slurry concentration can be controlled by adjusting the feed rate and the amount of reagent added.

c. Flotation time: Different minerals require different flotation times, and choosing a suitable flotation cell should be able to provide sufficient flotation time. This can be achieved by increasing the number of flotation cells or adjusting the size of the flotation cells.

d. Operational convenience: Choosing a flotation cell that is easy to operate and maintain can reduce production costs. You can consider choosing a flotation cell with a higher degree of automation.

4. Actual case analysis

Take the MQGg1830 model of the grate ball mill as an example, its processing capacity is 27t/h. When choosing a flotation cell, you can consider the following options:

Single-slot flotation cell: Select a flotation cell with a processing capacity of 30t/h, which can meet the processing needs of the ball mill. However, it should be noted that a single-slot flotation cell may affect the flotation effect because the pulp concentration and flotation time may not be easy to control.

Multi-slot flotation cell: Select multiple flotation cells with smaller processing capacity, such as 5 flotation cells with a processing capacity of 6t/h. This can not only improve the flotation effect, but also control the pulp concentration and flotation time by adjusting the feed amount and reagent addition amount of each cell.

5. Price and cost analysis

When choosing a ball mill and flotation cell, price is an important consideration. The price of a 300-ton ball mill produced by Yingkuang Group is about 100,000-500,000 yuan. The price of a flotation cell depends on factors such as its processing capacity, material and degree of automation.

Ball mill price: The price of a MQGg1830 model ball mill is about 300,000-400,000 yuan.

Flotation cell price: A flotation cell with a processing capacity of 30t/h costs about 50,000-100,000 yuan, while the total price of multiple flotation cells with smaller processing capacities may be between 100,000-200,000 yuan.

6. Conclusion

Choosing the right ball mill and flotation cell is crucial to optimizing the mineral processing process. By considering factors such as processing capacity, pulp concentration, flotation time and ease of operation, the mineral processing process can be ensured to be efficient and economical. At the same time, reasonable price and cost analysis is also the key to ensuring the success of the project.

When selecting ball mills and flotation cells, enterprises are advised to conduct detailed market research and technical consultation to ensure that the selected equipment can meet production needs and has a good cost-effectiveness. Through scientific and reasonable equipment selection and configuration, the ore dressing efficiency can be significantly improved, the production cost can be reduced, and the economic benefits of the enterprise can be improved.
