Vertical coal grinding mill is an advanced grinding machine, which is developed on the basis of home & abroad high technology and production experience combination of various mills. coal mill vertical is an ideal device that integrates crushing, drying, grinding, and grading conveying all together.

Work Principle of Vertical Coal grinding Mill:

The materials drop to the center of millstone through the lay-off tube, and the millstone, which is rotating at constant speed, scatters evenly the material to the outside by means of centrifugal force, making it form material bed with certain thickness. Meanwhile, the material is rolled and smashed by multiple rollers. The material gradually move to the fringe of millstone under the continuous of fringe force, when the leaving material meets the hot gas enter into mill through the vane and moves upward, entering the separator through the central casing of the mill, the material and the gas achieve sufficient exchange and moisture is evaporated quickly in the process. Powder concentrator controls the granularity of finished product at exit of roller mill, granules that are larger than regulated size are separated and fall to the millstone, while those materials satisfying the fineness requirement enter the finished product storehouse through the powder concentrator.

Features of Vertical Coal Grinding Mill:

1. Force-Feed Lubrication

System Force-feed lubrication system extends the service life of bearing by 2.5 times.

2. Maximum Particle Fineness

Traditional roller mill either uses a static separator or dynamic separator to separate fine powder from coarse particles.Vertical coal mill brings together both types of separators for more efficient, adjustable material separation.

3. 20-40% Electricity Savings

Vertical coal mill uses 20% to 40% less electricity than a traditional air-swept ball mill for the same amount of grinding task.

4. Great Drying Performance

Air-swept milling method allows our mill to handle coals of up to 10% moisture content via varying its air flow rate and temperature.

5. 80-85dB Noise Level

Vertical coal mill is just 20-25dB quieter than ball mill.

6. Occupying less area

Vertical coal mill only takes up 60% of space needed to accommodate an equivalent ball mill, while its specific surface area is only 50% to 60% of the ball mill.
