Effect of Feed Rock Size Distribution on Crusher Performance
If the ore feed to any gyratory or jaw crusher consisted entirely of large cubes or spheres of a size that would just barely enter the crushing chamber, the crusher could not be expected to produce anything like its normal rated capacity because the upper part of the crusher could not shatter the large pieces enough to keep the rest of the crushing chamber busy
What Is A Vertical Shaft Impactor (VSI) Primer? | Stedman ,
Feed size and characteristics will affect the application of a VSI The feed size is limited by the opening in the center of the rotor Normally less than 5-inch material is desired, but very large VSIs can handle up to 12-inch feed Another feature that will affect application is moisture, which can make the feed sticky
