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. And the ball mill grinder is mainly used for grinding cement, silicate products, new building materials, refractory materials, fertilizers, various ores and glass ceramics, etc. Besides, it is widely used in industries such as ore dressing, building materials, and chemicals. According to different grinding methods, the grinding process can be divided into dry and wet ways. In general, the minerers usually 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.

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

Ball mills sold by Fote Machinery manufacturer are unique in the following aspects. The product ball mill grinding enjoys the feature of fine discharging size and it has the following advantages like easy to use and operate, has high working capacity, simple operation, and reliable performance.

According to the material and discharging methods, the FTM Machinery dry ball mill and the wet ball mill can be the best choices, because they both have good abrasion resistance, large crushing ratio, superior technology, the national processing standard, high processing precision, and good quality.

After the grinding process of the ball mill, the discharging fineness is usually 200 mesh, and the fineness can also be adjusted.

The wearing parts of the ball mill grinding mainly refer to the liner. The wear and service life of ball mill liners are related to the cost and production effect of the ball mill equipment. Then, how to distinguish the The pros and cons of the ball mill ceramic liner? First, look at the casting and smelting process of ball mill liners. Secondly, whether the quenching and tempering treatment of lining is qualified, and finally is the material of the lining.

At present, common materials of ball mill liners on the market are high chromium cast iron, low alloy wear resistant cast steel, high manganese steel materials, etc. These three kinds of liners have good wear resistance.

the wide range of ball mill machine application

Ball mill is one of the most imporatant machines in ore derssing plant. it can be used to process many materials including gold, copper, granite, quartz, pebble, limestones, etc. The final product of the gold ball mill is ieal and also always can be use on cosmetic.
According to the actual grinding materials, China FTM equips the ball mill with suitable grinding media and changes traditional surface contact to line contact, so that the discharging size is more even and the yield is higher. We know the grinding methods of ball mill, then how does a ball mill work? Here is the introdoction.

Working principle of ball mill crusher?

The working principle of ball mill

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.

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

We all know that the ball mill is just the general terms of the different types of ball mill machine. It is mainly divided into the two knids: ball-type mill and rod-type ball mill.The ball mill and the rod mill are widely used in the dressing plant,then how to distinguish them?
Ball mill vs Rod mill

Ball mill vs Rod mill


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.


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.
The ball media

The rod mill media and ceramic ball mill media

Appearance ratio: Rod mill, whose appearance is the same as that of the industrial ball mill. The difference is that the ratios of cylinder shape are different. For example, the length ratio of the rod mill to the diameter is generally 1.5-2.0, and the inside lining plate on the end cap is the vertical plane. The length ratio of the barrel to the diameter of the ball mill is small, and in most cases, the ratio is only slightly greater than 1.

Different discharging methods

Among these ball mills, the most commonly used ball mills are lattice-type ball mill and overflow-type ball mill (named from the different discharging structure). While the rod mill does not use a grid plate for discharging, there are only two kinds: overflow-type and open-type. And the diameter of the hollow shaft in the discharging end is generally larger than that of a ball mill with the same specification.

Performance analysis: The characteristics of the rod mill are that the product is rough, but the particle size is even, and the coarse particles and the slime are little. Therefore, when the rod mill is working, the finished products are relatively light. Characteristic of the particle size is related to the condition of the rod-grinding ore. At the same time, the performance characteristics of ball mill are large production capacity, strong adaptability to materials, high fineness of materials and fine grain size. Besides, the ball mill is easy to grind finely, and significant in energy-saving, but the over-grinding phenomenon is serious.
