What is a ball mill grinding?

The ball mill equipment developed by FTM Machinery is a grinding machine, which uses steel balls as the grinding medium. According to different grinding methods, ball mill can be divided into the dry and wet ways. In general, we adopt the wet grinding method for the ore dressing.

What materials can be processed by ball mill grinder?

The ball mill machine can grind many kinds of materials like limestone, diabase, calcium carbonate, quartz stone, iron ore, copper ore, gold ore, grindable materials, non-metallic ore, non-flammable and explosive materials.

How does a ball mill work?

Working principle of ball mill grinder

Ball Mill Working Principle

Firstly, the materials enter the first chamber of the mill uniformly through the hollow shaft of the feeder. The ball mill liners have different kinds of steel balls. When the cylinder rotates, the FTM Machinery ball mill brings the materials and the balls to a certain height and then let them fall.After continuous impact on materials and balls, the materials are ground roughly in the first chamber.

Secondly, the materials enter the second chamber through a single-layer compartment board. And the chamber is lined with a flat lining plate, some steel balls inside, then Fote Machinery ball mill is grinding these materials further. Finally, the materials are ground into a fine powder.

Last but not least, the powder is discharged through the discharging raft to complete the grinding work.

Why does ball mill grinder attract so many miners to invest?

1.Investment Attractiveness. Ball mills are popular with investors in the mining industry due to their ability to produce fine particle sizes, ease of use, high productivity, straightforward operation, and steady performance, ensuring a promising return on investment.

2.Customizable Grinding Efficiency. The ball mills supplied by Fote Machinery are known for their fine grinding results, typically discharging materials at a fineness of 200 mesh. Importantly, this fineness can be adjusted to suit various process requirements.

3.Enhanced Liner Durability. Commonly used ball mill linings, including high chromium cast iron, low alloy wear-resistant cast steel, and high manganese steel, demonstrate robust wear resistance. This resilience extends the lifespan of the liners, consequently lowering maintenance expenses and improving the overall equipment efficiency for mining operations.

What are the similarities and differences between the rod mill and the ball mill?

Similarities

The working principle is basically the same. Regardless of the ball mill or the rod mill, when the cylinder rotates, the grinding media (ball or rod) installed in the cylinder body are lifted to a certain height, and then they are thrown at a certain linear velocity, so the grinding media causes some impact and crunch to materials of the cylinder body. Finally, the grinding work is finished.

Differences

Grinding media: The grinding media inside the cylinder are different. The ball mill media is the ball mill balls. The grinding media of rod mill is a steel section, and the ceramic ball mill is the ceramic ball, as is shown in the following picture.

Customer Case — Gold Ball Mill for Tailing Process

Raw material: Gold tailings

Capacity: 20T/H

A customer from Beaver, Utah said, “I have some tailings in my mine, and I want to process them into concentrates to improve the utilization rate of gold resources. The Fute salesperson made a special plan for me and used a gold ball mill to finely process these tailings, which ultimately met my needs and made the recovery rate of these gold tailings above 85%.”
