The mobile heavy-duty screening station is to screen large materials. The aggregate is transmitted through the crushing station to the feeding belt and conveyed to the screening system. The vibration motor vibrates at a high speed, so that the aggregate can be accurately screened through the three-layer screen. The expected ideal qualified material. Corresponding to three conveyor belts, they are transported out from the conveyor belt ports respectively, so as to achieve a sort of aggregate, and stack the aggregate of the same material type.
