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

Ball Mill Circulating LoadBall Mill Circulating Load

Ball Mill Circulating Load

 ·  · A the mill produces a diminishing percentage of finished material as the new feed rate increases. To maintain the same product distribution, the coarser mill discharge requires a larger circulating load to return the coarse fraction back to the mill. Therefore, to increase circuit capacity or produce a finer grind, higher circulating loads are required. As the circulating load increases ...

Report on Cement manufacturing process

 · Most cement is currently ground in ball mills and also vertical roller mills, which are more effective than ball mills. Clinker from the silos is extracted from the bottom through three vibro feeders installed in each silos. The clinker belt with a constant speed feed the clinker into cement mill. For OPC, gypsum is added and for PPC, pozzolona is added. The feeding of cement mill is done ...

In this step, pulps are repulped (if delivered to the mill in dry form), refined, and blended to give the desired furnish for the particular grade of paper. This blended stock is then pumped to the machine chest. From here it is pumped as thick stock through a tickle refiner, stuff box, and lastly the basis weight valve which controls the fibre delivery to the paper machine. Approach Flow ...
