SCREEN MODULE, PROCESSING DEVICE AND PROCESSING UNIT FOR INORGANIC MATERIAL Russian patent published in 2017 - IPC B07B1/49 

FIELD: mining.

SUBSTANCE: two-deck screen module for inorganic material contains the support elements, that are transverse beams, the upper screening device, attached over the transverse beams, the lower longitudinal supports attached under the transverse beams and holding under the mentioned lower longitudinal supports the lower screening device, forming together with lower longitudinal supports the through passage for the material flow over the mentioned lower screening device so as to direct the material subjected to screening at the mentioned lower screening device, in the longitudinal direction with respect to the given screen module. The module is equipped with the auxiliary housing for fixing the screen module to the body of the processing device for inorganic material. The screen module transverse beams are attached to the auxiliary housing. The lower screening device is fixed to the bottom of each longitudinal support. The module is attached to the processing device. The processing device contains at least one screen module.

EFFECT: increase of the screening efficiency, simplification of the screening devices replacement.
