Apr 27, 2016· The maximum for a VSI is about 1,000 tph, because of the limiting motor size and the rising Gforce of a highspeed rotor, which is calculated by multiplying the radius times the square of the RPM. Shoe configurations are many: rock on rock, groups of rollers, special tip wear parts and many others. The metallurgy of the shoes is also highly varied.

The size of the individual rock sample examined at the surface is rather small because it is limited by the size of drill cuttings and rock strength. Weak rocks, ones without cement, are often reduced to original detrital grain size by the drilling process, making it difficult to determine rock type, but still possible to determine lithology.
wastes time and reduces crusher capacity. The maximum feed size should be less than 80 – 85% of the nominal feed opening. This size distribution helps prevent blockage at the spider opening and allows a wellfilled crushing chamber that will evenly distribute the crushing forces • Power limit: Power consumption will vary based on
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 5inch material is desired, but very large VSIs can handle up to 12inch feed. Another feature that will affect application is moisture, which can make the feed sticky.
