But closed circuit system is adverse to open circuit system. The advantage of closed circuit system is eliminating over grinding phenomenon and reducing temperature of grinding chamber. Then the grinding efficiency and capacity is improved. In general, the capacity can be improved by 10%-20% compared with cement mill when these specifications ...

18-07-2016· Closed Circuit Ball Mill System. Clinker, Gypsum and other desired additives are fed to the ball mill in specific proportions based on the quality requirement. Feed material is ground in the ball mill, discharged and fed to a classifier with the help of a bucket elevator for classification of the ground cement into two streams – coarse and fines.

Water injection in to the mill The following examples show the effectiveness of spray water cooling in (open) and (close) circuit mill: Example-1: (open circuit) Cement temperature without spray (T1): 158 ºC Cement temperature with spray (T2): 103 ºC Cement flow rate (Fc) :14923 kg/h Specific heat of cement (Cpc): 0.20 kcal/kg.

Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates.
