  • Gyratory crusher including a variable speed drive and control system
    Patent number: 11027287
    Abstract: A system and method for controlling the operation of a gyratory rock crusher is shown and described. The gyratory rock crusher includes a variable frequency drive that allows the eccentric speed of the gyratory crusher to be modified based upon sensed parameters of the rock crushing system. The speed of the eccentric rotation can be dynamically adjusted to compensate for the size of the material particles being crushed and the availability of the material. The use of the variable frequency drive increases the operating efficiency of the gyratory crusher by controlling the discharge flow rate of the crushed material from the crusher and thus allows for a reduction in the size of the discharge hopper. The rotational speed of the eccentric is controlled to be below the critical speed for the gyratory crusher.
