1. Primary crushing. As the first stage in a crushing circuit, primary crushing reduces material to a size and shape that can be handled by a secondary crusher. Typically, the minimum setting on most primary crushers is about 4 in. to 6 in. Jaw, gyratory and impact crushers are most often appropriate as primary crushers, although there can …

Primary Crushing. 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

For primary crushing, high-chrome blow bars are crucial. For secondary crushing, low-chrome martensitic steel is the most appropriate material. If you're using a lower-chrome alloy, you should consider white-iron bars. These are more fragile than low-chrome martensitic-steel-steel alloys. Hence, when you need to replace a blow bar, the ...
