clinker nibs - Page 1 of 1 - International Cement Review

I suspect that it might be due to dusty clinker. High free lime clinker can result in a lot of dust entering the ball mill with the clinker. An excessive amount of fine particles tend to agglomerate and coat the balls, thus preventing direct ball-to-clinker particle impact and reducing the grinding energy being.

Clinker grinding with line - Page 1 of 1 - International .
