    Required production capacity is the final limiting criteria. Large primary horizontal shaft impactors can output up to 1600 TPH and more. 1000 TPH is about the maximum for a VSI because of the limiting motor size and the rising G-force of a high-speed rotor which is calculated by multiplying the radius times the square of the RPM.

  • Frequently Asked Questions: Jet Milling and Particle

    5. How is the output particle size controlled? In a jet mill with static classifiion (MICRO-JET JET-O-MIZER) the particle size is controlled by a combination of gas pressure and feed rate. With a constant feed rate of granular solids increased inlet gas pressure results in higher velocities and greater kinetic energy therefore a finer grind.
