VM - Vertical Grinding MillHome - Grinding Mill - VM - Vertical Grinding Mill
Vertical roller mill is a new kind of large scale grinding machine which is designed specially to solve the problems of low capacity and high consumption of industry mills. With a decade of years’ research of mills, Vertical roller mill is designed and manufactured based on our advanced design idea, and in combination with the European technology and the market demand.
VM series vertical roller mill is of reasonable and reliable construction, advanved process integrating drying, milling, separeting together. It can be used in various large-scale milling process, such as cement, metallurgy, chemical industry, non-metallic mine, to grinding the large material into the required powder.
- Low running cost:It has high grinding efficiency, the verical mill adopts roller and material bed to press and grind materials. It’s low in consumption, and its electricity consumption proportion can be 40% to 50% lower, with increasing of moisture of raw materials, electricity saving can be more obvious.
Low wear of mental, side plate and roller are of special materials, long life span, which is able to reduce running cost and generate higher utilizing ratio; - Low construction expense:The vertical mill is simple in process. Comparing with ball mill,its soil taking can be about 50% reduced, construction expense can be reduced by about 70%, which is small in construction area and space.The vertical mill is a combination of crushing, drying, milling, grading and transferring, which has simple system and compact structure. It can be allocated in the open air and its construction expense will be lower.
- It has powerful drying ability, the vertical mill adopts air to transfer materials, while grinding materials with higher moisture, wind-entering temperature can be controlled, which is able to prepare products to the final moisture requirement, materials with moisture of up to 12 to 15 percent can be dried in the vertical mill. Even drying ball mill is only able to dry materials with moisture of 3 to 4 percent.
- It has stable quality, even grain and grade. Materials stop a short period in the mill, which is helpful for testing and controlling of products’ grain and chemical composition and stable quality of products.
- Easy to maintain, after testing, cylinder, turn rotating arm, roller, liner can be changed in a short time.
- Environmental, and energy saving; it has small swing, low noise, less dust, which has clean operating environment and is adaptable to environmental requirements.
Mm to inch conversion: 25.4millimeters=1 inch
The humidity and hardness of raw material will affect the fineness and capacity.

Notes:
1. Material should be with hardness less than 7 in Mohs'.
2. Hot air is only necessary if outlet moisture is required to be less than inlet moisture.
3.When grinding material is difficult to grind, please use the largest power.
