When the vibrating screen is screening material, the materials will do circular motion on the box, so it is also called circular vibrating screen.
Vibrating Screen characterizes simple structure, high efficiency, reliable use and convenient installation, and can perform multi-special segmentation screening of loose materials. which is main equipment to separate soild materials, it is widely used in mineral, building material, coal dressing,energy, chemical industry,etc.
The vibrating sieve can be divided into mining vibrating screen, light fine vibrating screen, experimental vibrating screen, also can be divided into linear vibrating screen, circular vibrating screen, high frequency vibrating screen, double deck vibrating screen, single deck vibrating screen, and so on.
A vibrating screen is a necessary machine for mining and quarrying industries. In the quarrying field, the screening process always follows the primary and secondary crushing stages to divide rock material into more than three sizes from coarse to fine.
The working principle of a vibratring screen is quite simple. The crucial parts of the machine include vibrating screens, exciter, motor, screen decks, liners, and side plates.
Vibrating source comes from the exciter. During the process, the large material will stay on the top while the small and fine material can go throughout the screen mesh to the bottom, then you’ll get different sizes of materials.

Selection hinges on material characteristics (max feed size, hardness, abrasiveness), required throughput (tph), desired output size (CSS), available motor power, and budget. Careful analysis ensures optimal, cost-effective performance.
Proper installation requires a robust, level foundation and precise alignment. Correct operation involves thorough pre-checks, empty start-up, controlled uniform feeding, avoiding overload/choking, and following the proper shutdown sequence.
Daily checks include fasteners, lubrication, and visual inspection of wear parts. Regular maintenance involves deeper inspections and component servicing. Extend jaw plate life significantly through proper material selection, uniform feeding, pre-screening, and strategically rotating or flipping the plates.
Common faults include sudden stops (choking), reduced output, jaw plate issues, bearing overheating, excessive vibration, and toggle plate breakage. Troubleshooting involves systematically identifying causes like blockages, wear, loose parts, or improper settings.
Jaw crushers excel at primary crushing of large, hard materials due to their robustness. Cone crushers are better suited for secondary/tertiary hard rock crushing, offering higher reduction and better shape. Impact crushers produce excellent cubical product but wear much faster on hard, abrasive rock.
