The answer is a litle bit complex. The specific grinding power consumption for the tube mill for cement grinding can vary a lot.

A brief list of factors that influence both the mill production and the power consumption can be listed:

- grinding circuit (open or close)

- type of cement

- clinker composition (C2S:C3S) ratio

- clinker temperature

- percentage of clinker with grain size lower than 2 mm

- If slag or other additives are used

- grinding fineness of the cement

- if operate in closed circuit - what is the type of separator

- cement collecting system

- tube mills internal equipment (proper designed diaphragm and linings)

- tube mill driving system.

- cement collecting system

For a proper designed cement grinding department with tube mill, the department specific power consumption for producing OPC at 3200 Blaine can be 38-45 kWh/t

For vertical mill - 35-42 KWh/t

The main aplication for vertical mills for cement grinding was considered as a pregrinding unit for large capacities ■

It depends, I give the power consumption range as below:

Power consumption for ball mill: 20 - 450 KW

Power consumption for roller mill: 20 - 75 KW

Dear Shibang:

Approximate values at 3000 Blaine are

Ball mill 26 kWh/t

Roller mill 17 kWh/t

Roll press 13 kWh/t

for the same production rate what is the power consumed in these mills ? ■

Respondents, outside China, have given you per tonne power consumption values. What more do you want? After a sabbatical year. ■

Dear sir,

We offers varous grinding machinery such as ball mill, rod mill and crushing machinery such as roll crusher, hammer crucher and other machineries.

if you have the need of a mill, you can visit us for more detailed information. ■
