Question: How to Select a Secondary Crusher?

Reply: Hello, sir.
The purpose of secondary crushing is to produce several coarse-grade products – for example, road base aggregates – or to prepare material for final recrushing. If the secondary crushing is done with the purpose of producing railway ballast, the quality of the product is important. In other cases, normally there are no quality requirements, except that the product be suitable for fine crushing. In most cases, the goal is to obtain the best possible size reduction at the lowest cost. Cone crushers are often used for secondary crushing, due to their high capacity and low operating costs.
