High Purity of Material

LUM Ultrafine Vertical Grinding Mill can effectively control the product size, chemical composition and iron content, and ensure the purity and whiteness of finished materials.

Energy-saving & Economical

LUM Grinding Mill can accurately control grinding pressure, speed and other parameters. Compared with ordinary mills, the energy consumption is reduced by 30%-50%.

Easy to Maintain & Operate

LUM Ultrafine Vertical Grinding Mill adopts reversible structure. With the hydraulic adjustment system, vulnerable parts can be easily and quickly repaired and replaced.

Environmentally Friendly

LUM Ultrafine Vertical Grinding Mill is sealed and operates under negative pressure, characterized by no dust spillover, small vibration of equipment, low noise, and more environmentally friendly production.

Working Principle

Material falls into the center of the grinding disc via the spiral feeder. The main motor drives the disc, creating centrifugal force to spread the material. Crushed by rollers, large pieces break down, and small particles form a material bed for inter-particle crushing. Crushed material moves to the disc's edge, carried by airflow into the powder selector for classification. Unqualified powder returns for re-grinding, while qualified powder enters the dust collector as finished product. Iron impurities fall into the lower cavity, scraped to the slag outlet, and discharged.

FAQ

Can the powder separator of the LUM ultra-fine vertical mill achieve online adjustment of fineness?

Certainly. The powder selection machine of the LUM ultra-fine vertical mill uses variable frequency speed control, allowing the rotor speed to be adjusted online during operation. This enables real-time adjustment of the finished product’s fineness, without the need to shut down the machine.
What is the moisture content of the powder produced by the LUM ultra-fine vertical mill?

By adjusting the temperature of the hot air, the moisture content of the finished powder can be controlled below 0.3%, fully meeting the requirements of the high-end ultra-fine powder industry.
What are the functions of the control system of the LUM ultra-fine vertical mill?

The control system enables one-click start/stop of the equipment, real-time monitoring of operating parameters, online adjustment of fineness, automatic fault detection and recording, as well as statistical analysis of production data. It can also be integrated with the factory’s DCS system for remote control.
Can the grinding rolls of the LUM ultra-fine vertical mill be used with their surfaces turned over?

Yes, the grinding roller sleeves of the LUM ultra-fine vertical mill are designed symmetrically. When one side wears out to a certain extent, it can be turned over and continued to be used. This significantly extends the service life of the roller sleeves and reduces operating costs.
Can the LUM ultra-fine vertical mill be used for grinding calcium carbonate?

Certainly. The LUM ultra-fine vertical mill is a specialized device for processing calcium carbonate into ultra-fine powder. The finished product can achieve a fineness of 2500 mesh, with minimal loss in whiteness and stable production capacity. It is a key component of high-end calcium carbonate production lines.
What are the advantages of LUM’s multi-stage powder selection technology in ultra-fine vertical mills?

Multi-stage powder separation technology enables precise classification multiple times. The resulting powder has a very narrow particle size distribution, excellent particle shape, and high purity. It fully meets the quality requirements of high-end ultra-fine powders. At the same time, this technology significantly improves powder separation efficiency and reduces energy consumption.
