The VM series vertical mill is an improved grand mill equipment after many years' concentrated design according to a market need. The vertical mill is designed to solve the problem of technological problems of low production, high energy consumption and developed on basic of absorbing advanced European technologies.
Features of Vertical Mill
1. Low running cost:
(1) It has high grinding efficiency, the 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.
(2)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;
(3)Exterior circulation device is installed, which is able to reduce electricity consumption further.
(4)Size of feeding material is big, which is about 5% of roller's diameter, generally 40-100mm, thus secondary crushing can be eliminated because of big and medium vertical mill.
2. Low construction expense:
(1)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.
(2)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.
3. Operation is easy and reliable
(1) Automatic controlling device is installed, which can enable long distance control and is simple in operation.
(2)There is a device to prevent direct contact between roller and mill plate, which can prevent the equipment from fragmentation serious vibration.
4. It has powerful drying ability, the vertical grinding 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.
5. 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.
6. Easy to maintain, after testing, cylinder, turn rotating arm, roller, liner can be changed in a short time.
7. Environmental, and energy saving; it has small swing, low noise, less dust, which has clean operating environment and is adaptable to environmental requirements.
Application of Vertical Mill
The Vertical Mill is of reasonable and reliable structure design, integrated with advanced process, which is an combination of drying, mill, classification and lifting, especially in process of big mill, it can fully meet customers’ needs, all key technologies, economic index are all of advanced international level. Vertical Mill can be widely used in cement, electricity, metallurgy, non-mental ore and other industries, especially used to process various ores by grinding bulk shape, grain shape and powder shape raw materials to required powder materials.
