Circular Vibrating Screen for Crushed Ore and Stone

Short answer: a circular vibrating screen has one exciter that moves an inclined deck in a circle. The circular throw keeps a coarse, heavy bed loose and the slope carries it down, so it is the standard screen after a crusher.

A circular vibrating screen is often installed as an inclined vibrating screen so material travels down the deck by gravity. Deck count, including a double-deck circular vibrating screen, is quoted to the duty; we do not advertise a stock double-deck model without your feed data.

Specifications on request — send your material, capacity and mesh size.

Working principle

An eccentric shaft or unbalanced weights turn in bearings fixed to the screen box. The box, isolated on springs, follows a circular path. On an inclined deck that motion lifts and tumbles the bed: fines migrate to the mesh while the slope moves the load to the discharge end.

Position in the line

The usual place is straight after the jaw or cone crusher. Oversize returns to the crusher in a closed circuit, and the screened sizes go on to grinding, washing or storage. In quartz and feldspar plants the screened fraction is then milled, classified and passed through mineral magnetic separators to lower iron.

Single, double or multi-deck

Each extra deck adds one more product size from the same machine. A double deck circular vibrating screen is common where two cut sizes are needed after the crusher. The deck count follows your product list, so send your target sizes.

Selection checklist

Feed: material, top size and the share of fines or clay; whether it is dry, damp or a slurry.
Cut: the aperture or mesh you separate at, and how many products you need (this sets the deck count).
Throughput: tonnes per hour reaching the screen, including any circulating load from a crusher or mill.
Duty: dry sizing, wet sizing with spray bars, de-sliming or dewatering.
Screen media: woven wire, polyurethane or rubber panels, or perforated plate, matched to abrasion and blinding risk.
Plant interface: feed chute and discharge positions, structure height, and the local supply voltage and frequency.

Circular Vibrating Screen: questions

How does a circular vibrating screen work?

One exciter moves the spring-mounted box in a circle; on an inclined deck the motion loosens the bed and the slope carries material to the discharge end while undersize passes the mesh.

Is a circular vibrating screen used in closed circuit?

Often. Oversize from the screen goes back to the crusher, and the screened product goes forward.

Can PTMS supply a double deck circular vibrating screen?

Yes. Deck count is set by the number of product sizes you need.

How is a circular vibrating screen priced?

By screen area, deck count, screen media, construction and drive. PTMS does not publish prices; send your material, capacity and mesh size for a quotation by email.
