Secondary Crushing Equipment

The term “secondary crushing” has become well established and familiar through long usage; it applies to the crushing stage, either single or multiple, which follows immediately after the primary crusher, taking all or a portion of the product of the primary crushing stage as its feed. The term should not be used, as it sometimes is, to designate a particular type or size of crusher

Difference Between Sag Mill vs Ball Mill mech4study

Oct 12, 2017 Today we will learn about difference between sag mill vs ball mill. A mill is a machine by which solid or hard materials are broken into smaller pieces by means of grinding, crushing or cutting. This commutation is an essential part of many processes. Ball mill is a secondary, and it is used after the SAG mill

SAG mills (semi-autogenous grinding mills) TON

SAG milling extends itself to many applications due to the range of mill sizes available. They can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill and some or all of the work done by a ball mill. SAG mills are also an optimum solution for wet grinding since crushing and screening in these
