PTMS · Della Magnet Circular Vibrating Screen for Ore, Stone and Sand
A circular vibrating screen shakes an inclined screen deck in a circular path. It is the usual choice for sizing crushed ore, stone and gravel after the crusher. We configure deck count, screen media and size to your duty.

What is a circular vibrating screen?
It is an inclined screen box on springs with one exciter, an eccentric shaft or unbalanced weights, near its centre. As the exciter turns, every point of the box moves in a circle. The circular throw loosens the bed of material and the slope of the deck carries it downhill, so the screen handles coarse, heavy feed well.
How does a circular vibrating screen work?
- Crushed material is fed at the upper end of the inclined deck.
- The circular motion lifts and tumbles the particles, so fines work down to the mesh.
- Undersize falls through; with two or more decks the feed is split into several sizes at once.
- Oversize runs off the lower end, often back to the crusher in a closed circuit.
Applications
- Sizing crushed ore, limestone, granite, gravel and aggregate.
- Screening quartz, feldspar and silica sand before grinding or further processing.
- Closed-circuit screening with a crusher.
- Double deck circular vibrating screens when two cut sizes are needed in one machine.
When to choose a linear screen instead
If the material is finer, needs dewatering, or must be screened on a level deck because headroom is limited, a linear vibrating screen is often the better fit. For fine particles, see the high-frequency vibrating screen.
How to choose a mining vibrating screen
- Material and particle size: what you screen, the top size of the feed and how much fine material it contains.
- Cut size (mesh / aperture): the size you want to separate at, and the number of products (one cut or several).
- Capacity: tonnes per hour of feed to the screen.
- Wet or dry: dry screening, wet screening with spray water, or dewatering.
- Screen media: woven wire mesh, polyurethane panels or perforated plate, chosen for wear and blinding.
- Site details: available space, feed and discharge points, and your local power supply.

Frequently asked questions
What is a circular vibrating screen used for?
Sizing crushed ore, stone, gravel and sand, usually right after the crusher and often in closed circuit with it.
Can you supply a double deck circular vibrating screen?
Yes, the number of decks is configured to the number of size products you need. Tell us your feed size and target sizes.
Why is a circular vibrating screen inclined?
The circular motion loosens the material, and the slope of the deck carries it along. Without the incline the material would not travel to the discharge end.
What is the price of a circular vibrating screen?
It depends on deck size, number of decks, screen media and construction. We do not publish prices; send your material, capacity and mesh size and we email a factory quotation.

Linear vs circular vibrating screen
A linear screen moves material in a straight line and can work near horizontal; a circular screen uses a circular motion on an inclined deck and suits coarser sizing. We help you choose from your feed and cut size.
