Marble, originally referred to as the white and black-patterned limestone produced in Dali, Yunnan Province. Later, the name gradually developed into limestone, which is used to make architectural decoration materials, and is also known as white marble.


1. Reduce the roller and vibrate and improve the production. According to the calculation, Regarding to the YGM series Raymond 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 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 50-450 mesh. 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 Raymond mill, the YGM marble Raymond 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 YGM series Raymond mill has the advantages of high production, high qualification rate Low noise and vibration in grinding of the 50-450 mesh.
