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.
In the field of application, in view of the beautiful appearance after the marble is polished, it is often used to process various profiles and plates, and to make walls, floors, tables, columns and other materials of buildings, and can be also carved into arts and crafts. , lamps, utensils etc. In addition, after the marble is ground without iron sand, it can be added with resin glue to produce artificial marble. It can be also used for painting in the building, or use marble powder with a slightly larger particle size as construction sand.
Processing and preparing marble powder, I recommend Guilin Hengda’s HD series Raymond mill. Here are the advantages of Raymond mill.
1.Reduce the roller and vibrate and improve the production
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 by20% 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.
