FIELD: mechanical engineering.

SUBSTANCE: invention relates to the field of mechanical engineering. A two-chamber jaw crusher is proposed, which contains a drive shaft on which a crushing roller is mounted. On one side of the crushing roller, the first jaw plate is installed with the possibility of its rotation around the center D, the working space between the jaw plate and the crushing roller forms the first crushing chamber with an adjustable discharge gap A, a guide element is fixed above the jaw plate so that the distance between the guide element and the crushing roller forms an input gap E. The crusher additionally contains a second jaw plate, which is installed on the opposite side of the crushing roller from the first jaw plate. The second jaw plate has the ability to rotate around the center G, the working space between the second plate and the crushing roller forms a second crushing chamber with an adjustable discharge gap F.
