Which is the Better Options for Primary Crushing?

Q: I plan to build my aggregate production plant, i know the jaw and gyratory crushers are common machine used as primary crushing machine, but which is the better options?

A: Hello, thanks for visiting our website. Jaw and gyratory crushers are both capable of handling hard, abrasive rocks and selection is based upon throughput and maximum lump size. The selection of the primary crusher is not an isolated decision but must consider the blast design, excavator bucket size and dump truck selection. Larger throughputs usually dictate the handling of larger lump sizes but this is only effective if each piece of equipment is fully utilized. A compromise or optimum design of operations must be achieved comparing costs of drilling and blasting to reduce lump size with capital and operating costs of handling and processing larger lumps. For a given capital investment, the jaw crusher will be able to accept the largest lump size and for throughputs less than 2200tph a choice exists between the three types. For capacities significantly above 2200tph it is likely that the gyratory crusher will be selected upon this criterion alone.
