1. Power consumption
CLUM Ultrafine Vertical Roller Mill:
Depending on the abrasiveness of the raw material and the particle size of the product, the power consumption is also different
Compared with the ball mill, it can reduce the power cost by 30%~50%
Ball Mill:
High power consumption
2. Product flexibility
CLUM Ultrafine Vertical Roller Mill:
High-efficiency and flexible control product categories: it can produce ultra-fine powders with a specific surface area of 9,500 (d97 = 20 μ m) ~ 25,000 (d97 = 10 μ m) cm2/g at one time.
Ball Mill:
According to different proportions of steel balls, different products are produced.
3. Drying ability
CLUM Ultrafine Vertical Roller Mill:
CLUM mill is the new roller mill which can bring in a large air flow. So it is suitable for high moisture material grinding , conveying and drying .
Ball Mill:
When the ball mill grinds the wet material, additional drying equipment is usually required in front of the ball mill due to its limited air flow through the ball mill.
4. Equipment configuration space
CLUM Ultrafine Vertical Roller Mill:
Small, occupying only 50~70% of the space of the ball mill
Ball Mill:
Occupies a lot of space
5. Feeding fineness
CLUM Ultrafine Vertical Roller Mill:
Larger feed particle size: The feed size depends on the diameter of the grinding roller, which can directly process larger particle size raw materials without excessive crushing
Ball Mill:
Limited by its maximum steel ball diameter, only smaller materials can be fed
6. Product fineness
CLUM Ultrafine Vertical Roller Mill:
The CLUM roller mill uses a high and adjustable grinding pressure to produce a large amount of fine powder.
Ball Mill:
Ball mill also can produce very fine powder ,just the rate of superfine powder lower than CLUM mill (2 micron size content )
7. Particle size distribution
CLUM Ultrafine Vertical Roller Mill:
Ultra-fine vertical mill top match with advanced horizontal airflow classifier,which can separate all the finess powder.
Ball Mill:
If the ball mill is equipped with a conventional classifier, the parabola of the particle size distribution is steep.
8. Product conversion time
CLUM Ultrafine Vertical Roller Mill:
It is possible to convert different raw materials on the same mill in a very short time to produce different products.
Ball Mill:
Need much longer cleaning time
9. Contamination of abrasive materials
CLUM Ultrafine Vertical Roller Mill:
whiteness higher so much than ball mill, because wearing parts damage very less.
Ball Mill:
whiteness not good ,because ball will damage so much , the steel powder will pollute the products.
10. Grinding efficiency
CLUM Ultrafine Vertical Roller Mill:
High grinding efficiency and low wear: CLUM vertical roller mills use high pressure wheel to grind materials, such as calcium carbonate materials. In five years, the grinding roller only damaged 3 mm.
Ball Mill:
The ball mill uses collision friction, so the ball mill has low grinding efficiency.
11. Initial investment cost
CLUM Ultrafine Vertical Roller Mill:
A little higher than the ball mill, but it can get all difference cost back within 4 months.
Ball Mill:
Ball mill is cheaper than CLUM Mill
12. Operating cost
CLUM Ultrafine Vertical Roller Mill:
Low operating costs due to no grinding media consumption and low power consumption.
Ball Mill:
High operating costs due to abrasive media consumption and high power consumption.
13. Noise
CLUM Ultrafine Vertical Roller Mill:
The machine noise is much lower than the ball mill
Ball Mill:
Very big noise
14. Product whiteness
CLUM Ultrafine Vertical Roller Mill:
High whiteness
Ball Mill:
If steel balls are used as grinding media, the whiteness is low
15. Product particle shape
CLUM Ultrafine Vertical Roller Mill:
Poor sphericity
Ball Mill:
Better sphericity
16. Sensitivity to external conditions
CLUM Ultrafine Vertical Roller Mill:
Sensitive to metal foreign bodies
Ball Mill:
Ball mill is not easily affected by external conditions
Based on the comparison of these characteristics, you can choose ultra-fine vertical mill or ball mill based on your needs, budget and other conditions.
