Vibratory screens are essential in mining operations for separating and classifying materials by size. Here are the key parts commonly found in vibratory screens used in mining:
1. Screen Box/Deck
– The main frame that holds the screening media (mesh, panels, or plates).
– Can have single or multiple decks for layered separation.
2. Screening Media (Mesh/Panels)
– Wire Mesh Screens – Common for fine to medium separation.
– Polyurethane (PU) Panels – Durable, resistant to abrasion.
– Rubber Screens – Used for heavy-duty applications.
– Perforated Plates – For large-particle screening.
3. Vibrator Motor/Exciter
– Generates vibration to move material across the screen.
– Types:
– Electric Vibrators – Common in most screens.
– Unbalanced Weight Exciters – Used in circular motion screens.
– Electromagnetic Vibrators – For high-frequency screening.
4. Springs/Suspension System
– Supports the screen box and isolates vibration from the structure.
– Types:
– Coil springs (most common).
– Rubber buffers or marshmallow springs (for dampening).
5. Drive System
– Transmits motion from the motor to the screen deck.
– Includes belts, couplings, or direct drive mechanisms.
6. Feed Box/Hopper
– Channels raw material onto the screen evenly.
7. Discharge Chutes/Outlets
– Directs separated materials into different streams (undersize/oversize).
8. Side Plates & Cross Members
– Reinforce the screen structure and prevent material spillage.
9. Dust Covers (Optional)
– Encloses the screen to reduce dust emissions.

– Provides stability and elevation for proper material flow.
Common Wear Parts (Replaceable Components)
– Screen panels/mesh
– Tensioning systems (clamps, hooks, bolts)
– Springs
– Bearings (in vibrator assemblies)
