| Grinding Process | The grinding plate is rotated by the main motor via the reduction gear. Meanwhile, high pressure air enters the mill interior via the air inlet. Materials then fall onto the center of the grinding plate in rotation by the screw conveyor feeder. Due to the centrifugal force, the materials evenly move from the center of the grinding plate towards its fringe. While passing across the track in the grinding plate, large blocks of materials are crushed and grinded directly by the grinding roller. The fine particles form the material bed, owing to squeezing, where the inter-particle crushing takes place until grind to the fine powder. The fine powder continue to move towards the fringe of the grinding plate until they are taken away by strong air flow at the air ring. While the materials along with the air flow pass through the separator located above the grinding plate, the coarse particles return to the grinding plate for re-pulverization due to the action of the rotor blade, the fine particles along with the air flow leave the mill interior and are collected and discharged as finished powder product by the powder collector. |
| Final Product Quality Guarantee | The coarse granular and impurities will fall into the lower grinding chamber, and be discharged out by the scraping plate. High-precision multi-rotor classifier adopts frequency control, adjustable rotor speed, produces various particle size. Adjusting the hydraulic system pressure to change the roller pressure, fit for materials with different hardness. Electronic caging device makes sure the safety gap between roller and plate, effectively avoide the heavy vibration due to lack feeding. |
The raw materials are released and transmitted by the feeding belt conveyor from the raw material hopper, with the weight of the materials being controlled by the belt scale and the tramp iron in the materials being removed by the iron remover. Subsequently, the materials are sent to the elevator, via the air lock valve and screw conveyor, into the mill interior for pulverization. After pulverization, the qualified powder separated from the powder classifier is transmitted into the tank-type pulse dust collector, then after the screw conveyor and discharge valve they are transported to the final product hopper, packed ans sold directly. A small amount of coarse materials (colloquially "slag") is released out by the mill unit, and re-feed into the machine to be grinded again. The iron remover of the feeding belt conveyor ensures the operation safety of ultrafine vertical roller mill. |
In some specific fields, high quality powders are demanded especially for powders cut-off size, and 2μm content percentage, thus secondary or third classifier system will be added to meet the demand. With the ultra fine classifier as core equipment, the system includes buffering silo, bucket elevator, blower, air-proof discharging valve, classifier, pipes and ducts, bag filter, screw conveyor, pneumatic conveyor etc. |

Because of different kinds of hammer crusher , so our hammer crusher has different prices, I need to ask you some details for sending you the more suitable quotation: |
1.Which kind of material you are going to grinding? (Dolomite; Calcite; Quartz; Basalt; Barite; Feldspar ; Gravel; Bentonite; Gypsum; Granite; Coal; Slag; Pebble; Others ) |
2. What's the production capacity you want? How many tons or cubic meters per hour? ( > 100 TPH > 50 TPH > 30 TPH > 10 TPH > 1 TPH < 1 TPH) |
3.What's the granularity of the final products you need? (in milimeter, micron or mesh) |
4. What's the max input size of the material? (In inch,centimeter or milimeter) |
We will give you factory price with full specification,so pls leave us an inquiry to know more details about price, packaging shipping and discount. |
