WhatsApp: +86 18838072829We have a ball mill in our plant with 2m diameter and 7 m length. I think that It is not a standard ball mill. Now I want to calculate the power draw of this ball mill and know how much must be the loaded ball in this ball mill. Can I use the usaul formulas to calculate? Thankyou. d. David. 5 years ago.
