AMIT 135: Lesson 5 Crushing - Mining Mill Operator Training

In any operation that incorporates size reduction, selecting the primary crusher is vital to the overall success. The main parameters to first decide on a general type of crusher are the impact strength, product size and material hardness. The final design for a crusher will be selected primarily based on required capacity, feed and product size. · There are three main steps in designing a good crushing plant: process design, equipment selection, and layout. The first two are dictated by production requirements and design parameters, but the layout can reflect the input, preferences and operational experience of a number of parties. These can include the owner's engineering staff ...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 ….
