513· Ideally, the reduction ratio of a jaw crusher should be 6to1. 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.Crushing Equipment Superior Industries U.S. Manufacturer,Maximum Reduction Ratio 8:1 Maximum Production Rate 550 STPH (500 MTPH) — Materials: Benefication, Cement Clinker, Chips, Concrete Rock, Cubicle Products, Fractured Gravel, ManMade Materials, Manufactured Sand, Precious Metals, ReCrushing Shaping, Super Pave Learn More » Impact Crushers benefits of impact crushing
Roll Crusher Manufacturer & Design Williams Crusher
Williams single roll crushers reduce via a combination of impact, shear, and compression. The rolls are always toothed in patterns suited to the feed material. Single Roll Crushers generally handle larger feed sizes at higher reduction ratios in higher capacities and are particularly well suited to be used as lump breakers. Double Roll CrushersGyratory Crusher an overview ScienceDirect Topics,Inversely, at a given reduction ratio, effective streamlining could increase the capacity by 30%. The typical reduction ratio is bound to be between 6 and 8 and is similar that of jaw equipment. Applying the crushing force by rolling the nut breaks flats and gives a product that is more “cubic” than the jaw crusher. –
