What is the difference between vertical mill and ball mill?

12/01/2022 admin

Ultrafine vertical mills and ball mills are common large-scale industrial grinding equipment and are widely used. However, many people still do not know how to choose the most suitable equipment when purchasing equipment. Let’s take a look at the difference between ultrafine vertical mill and ball mill.

CLUM ultrafine vertical mill

CLUM vertical pulverizer is a new type of ultra-fine pulverizing equipment integrating grinding, grading and conveying. Can be used in chemical, metallurgical, non-metallic mining and other industries.

Advantages of CLUM Ultrafine Vertical Mill:

① High grinding efficiency and excellent quality of finished products

The grinding curve of the roller sleeve and the lining plate specially designed to realize the principle of ultra-fine grinding makes it easier to form a material layer, the grinding efficiency is higher, and the yield obtained by one-time grinding is high.

The special pre-compacting device can ensure that the material is effectively ground and the fineness of the finished product is guaranteed. At the same time, the vibration of the mill is small, and the power is effectively exerted.

Using the principle of material layer grinding, the material stays in the mill for a short time, reducing repeated grinding, the iron content in the finished product is small, and the whiteness and clarity of the product are high.

During the grinding process, adding a small amount of additives that do not affect the quality of the finished product can significantly increase the added value of the product.

② Advanced powder selection technology, high efficiency and energy saving

Using the principle of multi-head powder separator, the fineness of the ground products can be achieved within the selected range, without the existence of lower materials.

The PLC control system is used to accurately control the main parameters such as grinding pressure, turntable speed, and powder separator speed, which ensures the accurate cutting particle size and high reproducibility of the product.

Ultra-fine grinding and multi-head powder selection can save energy by 30%-50% compared with ordinary mills when producing products of the same fineness grade and have better economic effects.

③ Intelligent control system, stable and efficient operation

Adopt PLC/DCS automatic control grinding roller pressure control method, the grinding pressure control is precise, and the operation is efficient and stable.

Automatic control system, which can realize remote control and easy operation.

The speed of the main engine is controlled by frequency conversion, and the materials are widely used.

In order to prevent the contact between the grinding roller sleeve and the grinding disc liner, electronic limit and mechanical limit protection are adopted to avoid severe vibration and destructive impact, and the machine runs more stably.

The grinding roller lubrication adopts a separate lubrication station, and the single grinding roller circuit adopts the mode of double-pump pressure and suction working at the same time, which not only ensures that the grinding roller bearing is fully lubricated and cooled, but also make sure that the roller bearing chamber does not leak due to excess oil.

④ Easy maintenance and low operating costs

The grinding roller is not in direct contact with the grinding disc during work, and the grinding roller and the lining plate are made of high-quality materials, with long service life and less wear.

The grinding roller can be turned out of the casing for maintenance, and the replacement of the grinding roller sleeve and the lining plate is convenient and quick, reducing the loss of downtime.

⑤ Environmental-friendly

Special structure design and working principle, the equipment has low vibration and low noise.

The equipment is sealed as a whole, the system works under negative pressure, there is no dust overflow, the environment is clean, and it meets the national environmental protection requirements.

Ball mill

Ball mills are mainly used in metallurgy, chemical, electric power, cement and other industrial and mining enterprises to grind various ores and other grindable materials. Strong adaptability to materials, continuous production, large crushing ratio, and adjustable finished product fineness.

The open circuit system and the record system can be set up according to the needs. According to the production method, it can be divided into dry production and wet production, or grinding and drying can be carried out at the same time.

Ultrafine vertical mill VS ball mill

Product performance

Ball mill: Generally, produce 45um thick body; ultra-fine ball mill can produce 10um powder; ceramic ball mill has high whiteness and the lowest iron content.
Good grain, spherical

Ultrafine vertical mill: The content of 2um is 30%-70%, D97=4-45um, the fineness of powder can reach 8.5um at one time, and the specific surface area is high

Equipment performance

Ball mill: It is suitable for a wide range of materials, a wide range of particle size of the finished product, a wide selection of grinding media, high energy consumption and high noise. Producing different specifications of powder, long switching time. Difficulty in fineness adjustment.

Ultrafine vertical mill: There is no contact between the roller and disc, the vibration is small, and the operation is stable. Low energy consumption and large output. The production of finished products of different specifications can realize rapid switching. The products are highly professional, and the initial investment is relatively large.
