Vertical Roller Mill for Raw Material Grinding

2020-09-28 | Author: SBM

Although the vertical mill in China has started for not very long time, it grows fast and has making great progress. It has been widely used in modern industrial grinding because of its excellent technical performance, especially for cement clinker and slag grinding.

Nowadays, there are many production cases have shown that SBM's vertical grinding mill is more suitable for cement, coal processing and other industries, and has a strong advantage in the application.

LM Vertical Grinding Mill

Based on the absorption of advanced technologies of famous international corporations, LM Vertical Grinding Mill integrates five functions of crushing, grinding, powder selection, drying and material conveying. It is characterized by centralized technological process, small occupational area, low investment, high efficiency, energy conservation and environment protection.

Low investment cost

LM integrates crushing, drying, grinding, separating and transport. The structure is simple while the layout is compact. Its occupational area is about 50% of that of the ball-milling system, which greatly reduces the investment cost.

Lower Operating Costs

(1)High efficiency:The grinding roller directly grinds materials on the grinding disc with low energy consumption. It can saves 30 to 40 percent energy consumption compared with ball mill.

(2)High wear-resisting: Because the grinding roller is not in direct contact with the grinding disc (and the grinding roller and lining plate are made of high quality materials), its service life is long.

Easy to operate

The mill equips automatic control system which can realize remote control, easy to operate. In addition, the powder concentrator adopts frequency conversion control, which is good for adjustment with uniform particle size.

High quality finished products

The iron content in the product is very low, and the iron generated due to mechanical wear is easy to be removed, thus effectively guaranteeing the whiteness and purity of the material.

Safe and reliable

LM vertical grinding mill has explosion-proof design to ensure the safe production of equipment.


The system is sealed in an integral manner and works under negative pressure, so that there is no dust spilling and the environment can keep clean with the emission standard far better than the international standard.

LUM Ultrafine Vertical Grinding Mill

LUM grinding mill adopts the latest Taiwan grinding roller technology and German powder separating technology. It has become a better choice in the ultrafine powder grinding industry.

Higher Yielding Rate, Better Quality

Using the material layer grinding principle, the material stays in the mill for a short time to reduce repeated grinding, ensuring the finished products less iron content, high whiteness and clarity. LM adopts specially designed grinding roller sleeve and lining plate so that the materials can be ground to the desired fineness (0.045-0.02mm) in one time.

Low consumption

SBM adopted PLC control system and multi-head powder separating technology in this grinding mill. Users can accurately control the grinding pressure, revolving speed and other equipment working parameters. Compared with common grinding mills, the mill can reduce energy consumption by 30%-50%.

Simple and safe operation

The mill adopts PLC/DCS automatic control system without manual operation. Meanwhile, independent roller lubrication system can fully lubricate and prevent oil leakage

More environmentally friendly

LM has the characteristics of small vibration, low noise and well-sealed, no dust spill, in line with environmental protection requirements.

Generally speaking, grinding belongs to a production process. Both LM Vertical Grinding Mill and LUM Ultrafine Vertical Grinding Mill have accumulated a lot of experience with technical advantages in the production and application. So SBM can provide you with mature and reliable grinding solutions in the design and consultation of grinding project, help you to reduce costs and gain greater output value.
