  • Method and an apparatus for controlling a crusher
    Patent number: 4212429
    Abstract: A method and apparatus for controlling an autogenous or semiautogenous crusher, in which the quantity of charge within the crusher is determined continuously. The speed of rotation of the crusher is controlled in accordance with a function which links the speed of rotation of the crusher to the quantity of the charge in the crusher. In a preferred embodiment, the charge is determined from the resistance experienced by the motor which drives the crusher. This resistance is a linear function of the charge within the crusher. The control apparatus provides an electrical signal which is proportional to the quantity of charge and the electrical signal is then used to control the speed of rotation of the crusher.
