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) Feed Rate: 160 to 13,000 tph

Mills require different liner profiles and designs depending on mill size, speed, charge, charge level, type, size of grinding media, expected service life, and – of course – ore size and properties, such as hardness and abrasiveness. SAG mill A SAG mill is usually a primary mill for grinding coarse ore directly from the crushed stockpile.

Abstract. Comminution circuits based on SAG (semi-autogenous grinding) mills are not necessarily power efficient. So- called critical sized particles can build up in the SAG mill charge, limiting mill throughput, and increasing unit power consumption. Removing the critical size particles from the mill, crushing them, and returning them to …
