[0025] The specific implementation method of this embodiment is: before preparing round granular raw ore, the ore particles are screened once to remove the ore blocks contained in the ore particles. After these ore blocks are screened out, they are transported back to the crushing equipment and crushed again to meet the needs of preparing round granular raw ore. This application is a screening device prepared based on screening ore blocks.

[0026] By pouring the ore particles to be screened into the screening mechanism from the feed port, the driving structure is started to work before pouring the ore particles, and the driving structure drives one end of the screening mechanism to rotate.

During the screening process, the ore blocks continue to move along the inner wall of the screening mechanism until they move to the discharge port, and then are discharged into the collection component through the discharge port. The ore blocks are collected at one end and packaged and conveyed to the crushing equipment for further crushing.

[0027] Preferably, the screening mechanism is tilted and the height of the discharge port is smaller than the height of the feed port, so that during the rotation of the screening mechanism, the ore particles and ore blocks are driven to move along the inside of the screening mechanism under the action of gravity, so that the screening of the ore particles and ore blocks is completed during the movement, thereby achieving the purpose of fully screening the ore blocks in the ore particles.
