ABSTRACT:
In an apparatus and method for producing sand from stone, the stone is first crushed in a centrifugal crusher and then filtered through a screen. The stone retained on the screen is further crushed by a vibration mill. The stone passing through the screen and the stone crushed by the vibration mill are combined and then are filtered through a separater to separate out the minute particules. Measurements of various flow rates and particle sizes are made in order to control the rotational speed of the vibration mill and the rate at which stone is supplied to the screen.
