Vertical roller mill is widely used in the mine grinding process

Ore crushing grinding process is mine mineral processing of the most critical of a process, crushing and grinding process of mineral processing is also one of the most important technologies. How to select the high performance, low energy consumption crusher, vertical roller mill, is the key to protect the normal production of mining enterprises.
In actual production, various types of crusher have different specifications, different use range. At present, concentrator crushing multi jaw type crushing machine or gyratory cone crusher; crushing the standard cone crusher; crushing the short head cone crusher.
In the mine crushing, milling process, ore crushing operation is broken coarse crushing operations, and therefore its broken loose volume have increased. For preventing broken crusher cavity may thus causing obstruction, without increasing the discharging port to ensure desired row partical premise, must by increasing the broken at the lower part of the cone diameter to increase the total discharge section. The commonly used cone crusher in mine production is mainly used in the conventional crushing process as the second section broken and the third section broken.. In recent years, the use of the cone crusher in the domestic market is not only individual mines, but also the imported cone crusher.. At present, the maximum processing capacity of the cone crusher in the world can reach 1200t / 25mm under the condition of H discharging port..
Vertical roller mill is a kind of fine grinding equipment which is vertical and equipped with stirring device.. Material from the lower part of the mill to the income, to feed the grinding media and qualified products due to the density and spilled from the top of the mill, coarse particles are in the mill to grinding. The maximum coal feeding granularity of the vertical mill is 6mm, the granularity of the product is from 74 to 2 m. At present, the largest foreign vertical mill installed power 1500HP, processing capacity of up to a few hundred T / h.
Vertical roller mill is a advanced grinding equipment based on the extensive use of domestic and foreign advanced technology, combined with many years of various mill production experience, design and development. Is a set of crushing, drying, grinding, grading and transportation in one of the ideal equipment for milling industry. LM series of vertical mill can be widely used in cement, electric power, metallurgy, chemical, non-metallic minerals and other industries. For bulk powder materials, granular and powdered raw materials into the required.
Vertical roller mill grinding and milling system of high efficiency, energy saving 30% compared to 40%. Wear less, drying ability. Equipped with automatic control system, remote control can be realized, and operation is simple.. Equipped with roller and disc device to prevent direct contact of the lining plate, avoid destructive shock and vibration. Through the maintenance cylinder, flip the boom, the replacement roller sleeve, lining board is convenient, reduce downtime loss. The operation of small vibration, low noise, and the overall system of equipment, the system is under negative pressure, no dust spillover, the environment clean, meet the national environmental protection requirements.
