Lower Power Consumption and Higher Output Vertical Roller Grinding Mill



     The vertical roller mill special features: (1) Special hyperbolic arc surface design, larger contact area, high concentration of grinding pressure in grinding area. (2) Change from ordinary double-roller design to three-roller design to improve grinding efficiency. (3) Each grinding roller uses a double-cylinder inclined-pull design, and the high grinding pressure makes the material easier to crush. Because the centrifugal force and the inclined grinder guide the material to the retaining ring, the ultra-fine vertical roller mill has the advantages of uniform material layers. Other flat grinding rollers will cause material accumulation in front of the retaining ring and reduce the grinding efficiency.


     Vertical Roller Mill special mechanical design and material: (1) Grinding roller pressure. Although the grinding pressure was reduced to 1000 kN / m3, the synthetic peak grinding pressure was 220 MPa, which is higher than any other vertical roller mill on the market. This high grinding pressure is generated by the narrow grinding area on the outer diameter, thus ensuring the highest grinding efficiency. (2) Wear-resistant parts: The wear-resistant parts are made of wear-resistant alloy materials, and the wear rate of bushings and lining plates is 2 ~ 3g / t. Because it can be repaired repeatedly, it is considered to be the “green method” and can be recycled even when the service life of the wear-resistant parts is over. This is a more environmentally friendly approach than using any type of ceramic material (ceramic materials are difficult to repair and use, and are considered inanimate materials).


     Directly add chemical additives into the vertical roller mill to achieve surface modification: Another advantage of vertical roller mill is that it can directly modify and activate the powder in production. Through special process design, strictly adding chemical additives quantitatively and controlling the temperature inside the mill, after repeated tests on the vertical roller mill, the chemical additives are fully coated on the surface of the inorganic non-metallic powder. Using this kind of directly added chemical additives to achieve surface modification at one time, there is no need to purchase additional special modification equipment, which greatly simplifies the process and reduces investment costs. The functional powder produced by this method is widely used in the artificial marble market of superfine heavy calcium.


Working Principle of Vertical Roller Grinding Mill:


     The reducer makes the grinding table rotate. The crushed calcium carbonate conveyed to the grinding house by belt conveyor or screw conveyor falls down onto the grinding table because of gravity. With help of the centrifugal force of the rotating grinding table, calcium carbonate move from center to edge. And at the same time, calcium carbonate is ground between roller and ring. After being ground, the fine powder goes through the classifier into the pulse-jet collector with the help of air blower sucking. Coarser material will fall down to the mill again due to its large self-gravity and get reground.


The Advantages of Vertical Roller Grinding Mill:


1. Wide powder fineness range: calcium carbonate ultrafine roller grinding mill use turbo air classifier, which can produce a wider range of powder sizes. There are 30%~70% in the 2μm range, D97=4~45μm; the specific surface area is 21000 cm²/g, while products with D97=8.5μm can be directly produced by the mill.

2. Lower power consumption

3. The powder produced by ultrafine vertical roller grinding mill has a narrow particle size distribution, control gap of 2μm powder content, high profit margins and added value.

4. After being improved, rollers, grinding table, diversion systems and internal circulation systems can greatly improve the grinding efficiency and increase output by 15%~30% compared to the same type of domestic products.

5. Lower vibration and lower noise

6. Environment-friendly and 99.99% of the powder can be collected.

7. Reliability:

(1) The mechanical limit device for the roller is capable of being adjusted so as to ensure the safety clearance between the roller shell and the liner plate on the grinding plate. This effectively removes the possibility of the materials feeding interruption thus fierce vibration and destructive impact and maintains the safe an economical operation of the mill.

(2)Newly-designed roller sealing component ensures the reliable sealing without sealing the fan, which can lower the oxygen content in the mill to prevent the possibility of explosion.

8. Environment-friendly:

(1) Lower vibration and noise

(2) Perfect sealing and negative pressure guarantees no air pollution in the workshop.

(3)Vertical mill is the better equipment to lower power consumption in the mill industry, which is also what the country advocate and a must to increase the enterprise competitiveness in China powder industry.

9. High Automatic Level: PLC automatic control system enables remote control and easy operation and maintenance, which lower the labor cost.
