• Jaw Crusher an overview ScienceDirect Topics

    The speed of jaw crushers varies inversely with the size, and usually lies in the range of 100350 rpm. The main criterion in determining the optimum speed is that particles must be given sufficient time to move down the crusher throat into a new position before being nipped again.

  • Roll, Pitch, and Yaw How Things Fly

    Flaps are located on the trailing edge of each wing, usually between the fuselage and the ailerons, and extend downward (and often outward) from the wing when put into use. The purpose of the flaps is to generate more lift at slower airspeed, which enables the airplane to fly at a greatly reduced speed with a lower risk of stalling.
