Cone Crusher Sizing & Selection To Maximize Production

Balance Throughput & Reduction Ratio. Sometimes production capacity needs to be given priority over reduction ratios and vice versa. You can optimize for one over the other by adjusting certain cone crusher parameters. For maximizing capacity, use a flatter crushing chamber, larger head diameter, faster eccentric speeds, and shorter stroke ...

Crushers: 5 types and their main failures

They provide a reduction ratio of 3:1 to 6:1. Jaw Crushers feature a moving piece of steel (called the pitman) and a stationary piece of steel that form a V-shaped chamber. Material that enters the chamber is crushed to size between the moving piece of steel and the stationary piece of steel. Most of the crushing action occurs in the bottom ...

Roll crushers | PPT

4. ROLL CRUSHER Roll crushers are used for producing additional reductions in the sizes of stone after the output of a quarry has been subjected to one or more stages of prior crushing. Roll crushers have a theoretical MAXIMUM reduction ratio of 4:1. If a 2 inch particle is fed to the roll crusher the absolute smallest size one could expect from the crusher is 1/2 inch.

Tips to maximize crushing efficiency

Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor. The reduction ratio is then calculated by comparing the input feed size passing 80 percent versus the discharge size that passes 80 percent.

Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).
