Predicting the overall specific energy requirement of crushing
网页2009年5月1日 In this circuit primary crusher product is reduced to a HPGR circuit feed P 80 of 35 mm by closed circuit secondary crushing. The HPGR is also in closed circuit and reduces the 35 mm feed to a circuit product P 80 of 4 mm. This is then fed to a closed circuit ball mill which takes the grind down to a P 80 of 106 μ.A.2.1.

Perfecting the Performance of Secondary Crushers EMJ
网页2023年2月14日 Ideally, the deck on the scalping screen should have a cut point equal to the closed side setting (CSS) of the crusher. The feed size to a secondary crusher is typically in the range of 50 mm to 250 mm (up to 300 mm). If the capacity is higher, the acceptable feed size gets larger. After crushing, the product is in the range of 0-60 mm
