HD1280 specifications: Ring diameter: 1280 mm Roller size: 370*240mm Center speed: 125-150r/min Max feeding size: 20mm Final product size: 80-500mesh Capacity: 1.5-10t/h Dimension: 8500*7500*8200mm Total weight: 19t The biggest Grinding machine in the Asia HD2500 Raymond grinding mill grand launched Breakthrough the bottleneck of the grinding mill The greatest capacity grinder of Asia alone The processing capacity of each machine is 60t/h The processing capacity is 30% high than the capacity of the R type Raymond mill. The first choice for large scale ore non-metal powder processing The production fineness is 80-400 meshes Features 1.Reduce the roller and vibrate and improve the production volume according to the calculation, Regarding to the HD series grinding mill, under the sufficient grind force, the rollers is reduced and the grind space can be increased, The material layer filled better between the roller and ring, the attrition between rollers and rings is low, and the  vibration and noise are also reduced, at the same time, the  resistance of airflow of the fan becomes less. Winds can flow freely, thus the winds increase greatly, which determines the increase in the production volume. The production volume is 20% to 30% higher than R Raymond mill. 2.The increase mechanism of linkage pressure of the rollers, which greatly prolongs the useful life of the equipment and increases the capacity by 20% under the same power. 3.With the original roller assembly, the oiling time increased 6 - 15 times, archive the application of oil once, use for 30-45 days 4.High efficiency and stability, the ring and roller always contact during processing, the efficiency and stability of the grind are improved 5.Higher Accuracy powder Classify, without coarseness missing, Variable frequency Squirrel cage classifier�Patent product� is adopted, the accuracy is 80-600 meshes. The classify efficiency reached 99%. The powder selection is stable and adjustable, compare with the blade type, it can greatly improve the powder selection efficiency and qualification rate of the Final product. 6.High efficiency and energy-saving centrifugal blower, the blower is crucial in the operation of Grinding mill, the HD series grinding mill adopts the high efficiency Impeller type energy-saving blower which efficiency is highly improved than straight blade fan. 7.Low noise and vibration: with the reasonable set of Collocation of above, the HD series has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 325-400 meshes. 8.It's applied to the non-metallic non-flammable non-explosive minerals with water content less than 6% and the Moh's hardness under 6.
