General 640 Mobile Crusher: Jaw and Impact Stages in One System

The General 640 mobile crusher has been recorded in this video together with its entire circuit on the working site. The footage begins with the feeding of the jaw crusher and continues uninterrupted up to the second stage, where the material is transferred to the impact unit.

When the camera climbs onto the screen platform you can see the products separated by the decks being distributed to individual belts, with a cone of a different grain size forming at the end of each belt. The oversize from the screen being sent back to the crusher by the return belt makes it visually verifiable that the line runs in closed circuit.

The dust suppression nozzles stay open throughout the recording.

Combining a jaw and an impact crusher in the same mobile system means that staged production can be carried out with a single machine. When balanced feeding is maintained as in the video, the cubical ratio of the final product rises and screen efficiency does not drop.

This structure, which can be moved from quarry to jobsite in a short time, offers a clear advantage on seasonal and piecework jobs. For the stage arrangement and technical details of the system the General 640 mobile crushing and screening plant page can be reviewed.
