A hammer mill is typically good for grinding softer materials with Mohs hard-ness ranging from 1 to 5, while a jet mill can grind materials with Mohs hardness as high as 10. High hardness materi-als become very abrasive therefore, they are not suitable for high-speed hammer mills. In a typical jet mill, grinding.
The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8 1. Feed ROM up to 1.5 m. Product -300mm (for transport) to -200mm (for SAG mill.

Hardness of the ore and the ore feed size required for the grinding mill. Rod mills and balls accept ore crushed to less than 1 to 1-1 2 inches, and autogenous and semi-autogenous mills (where the ore acts as all or part of the grinding media) can accept ore as coarse as 6 inches in diameter. Grinding is usually done wet using recycled.
The Kansanshi mine in Zambia is the eight largest copper mine in the world, with two open pits.
