1.If grind *1.5mm limestone powder,the wearable for roller and liner is not more than 5g/t. So it can continuously use around **2 years.
2.Less air pollution . The noisy is less than *0db. There is no blower in Sand grinder, in this case there is nearly no dust pollution. If there is proper discharge air in bottom, it would be better.
3.Easy maintenance .During maintenance, you just need to do lubrication on time. There is less breakdown, high running rate. Longer working life for wearable parts. Easy to change wearable part. Roller can be repaired by surfacing.
4.Lower power consumption. During grinding *1.5mm limestone coarse powder, the power consumption is ***2 kwh/t.
​Grinding characteristic **-Grind desulfitation limestone

1. After the first time grinding, most of production is powder. <1mm takes around *0%. After separation, it takes *1~*0.1mm. Regarding to different inquiry, this can be adjusted.
2. Bcos of special working principle, during grinding limestone, after several times grinding and curlating, internal stress of limestone is broken. There is many microcrack in limestone powder. Amount of porosity which is inside of the grain is increased. So that the specific surface is increased, the active of limestone powder is increased. This makes desulfitation become faster.
3. The production size is easy to adjusted. Most of grain is collected around D*0. It fit for CFB boiler enquiry.
