Abstract
A method for operating an aggregate material processing plant according to two alternative modes of operation. In a first operating mode, unprocessed aggregate material is deposited onto a crusher feed conveyor and then fed to a crusher. The crusher produces crushed aggregate material, which is conveyed by a collection conveyor to a vibratory screen assembly at a first speed. The vibratory screen assembly sizes aggregate material deposited onto an upper screen deck thereof. Unscreened aggregate material is conveyed by a transfer conveyor to the crusher feed conveyor. In a second operating mode, unprocessed aggregate material is deposited onto the vibratory screen assembly, which sizes the aggregate material. The transfer conveyor conveys unscreened aggregate material to the crusher feed conveyor. The crusher feed conveyor feeds aggregate material to the crusher, which produces crushed aggregate material. The collection conveyor conveys crushed aggregate material to the vibratory screen assembly at a second speed.
