Hammer crusher. Hammer crushers are widely used in the cement industry. They are used for size reduction of hard to medium hard limestone, and sometimes for marl crushing. Hammer mills work with reduction ratios as high as 1 : 60; depending on the crusher feed, this ratio can increase to 1 :80.

conducted at two mines, a crushed limestone mine located in Pennsylvania and a gold mine located in Nevada. In the case of the limestone mine, a dust survey was conducted at an underground dump/crusher facility to quantify dust levels before the potential installation of an improved ventilation system designed to reduce dust at the location.
