The GRM series vertical mill is the grinding equipment successfully developed by Xinxiang Great Wall on the basis of introducing the world advanced grinding technology. There are nearly 40 technologies awarded national patents. It integrates powder grinding, drying, selecting powder and conveying. Compared with traditional grinding equipment, it has remarkable energy saving effect. Xinxiang Great Wall has produced more than 150 sets of various specifications GRM series since its first vertical mill was produced in 2008, and its products have been exported to Indonesia, Uzbekistan, Pakistan, South Korea and other countries and regions.
Applicable materials: Cement raw materials, clinker, slag, steel slag, coal, metal and non-metal ore and other materials.
Capacity: 10t/h-500t/h (depending on raw material characteristics)
Feeding particle size: 20-80mm
1. Advanced technology: More than 20 national patents are guaranteed by referring to Germany's Loesche grinding technology.
2. Energy saving and environmental protection: The grinding part adopts the structure form of flat disc cone roller with high efficiency and low energy consumption, which can reduce power consumption by more than 30% compared with the traditional ball grinding process;
Powder grinding, drying and classifying are all completed under the internal negative pressure of the mill. The sealing performance is good, and there is small dust pollution.
3. Easy operation: DCS central control system is adopted in the system. All operation parameters can be adjusted in the central control system. The system is quick in reaction and easy to operate.
Adopting the combination of dynamic and static efficiency cage type classifier, the fineness of finished product is controlled strictly, which can be adjusted freely according to the demand.
4. High operation rate: Continuously optimize the design of hydraulic system, lubricating system, wear-resistant parts, etc., which can effectively extend the service life of wear-resistant parts, reduce vibration, and make the operation rate of equipment as high as over 95%.
