As it turned out, designers are now adding secondary or pebble crushers to SAG circuits, on both greenfield and retrofit projects, to increase feed rate to the SAG mill. In other words, crushing plants, from primary to quaternary circuits, are here to stay. There are three main steps in designing a good crushing plant: process design, equipment

Crushers Primary Units Plant; 30 2a 20 Primary Jaw Crusher India; ... The primary difference between HSI and VSI crushers comes down to the direction from which the impact forces are applied to the material. With HSI crushers, the rotor hammers or blow bars strike the feed horizontally, delivering the crushing force along the rock's natural ...

Where the material is not reduced sufficiently in the primary crusher, it is then crushed by a secondary crusher to achieve the correct size of the material. Wear on parts of the crushers affect the performance and volume of material being crushed, the parts subject to high impact, and abrasive wear include the hammers, rotors, teeth, and mantles.

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
