Equipment / Wet processing / Screening & trommels

Trommel screens & vibratory screens

Rotary trommels scalp and size bulk feed by aperture; stainless-steel vibratory screens handle fine screening of slurries, powders and granules.

Shaftless scalping trommel with red bar-screen drum and twin motor and gearbox drive

PT-TS Shaftless scalping trommel

Rotary screening for coarse-material separation

Rotation turns the feed across the drum and separates it by aperture size. A shaftless layout reduces opportunities for material to wrap around a central shaft and supports scalping and pre-screening duties.

Focused applicationsSand / stone separation, earth / stone screening and feed preparation.
CustomizationDrum diameter and length, bar specification and aperture size.
Selection inputsWetness, stickiness, maximum lump size, debris and target fractions.
SpecificationsOn request, after your feed data or sample are reviewed. Price on request.

Screening performance depends on the aperture, drum configuration and feed conditions.

Shafted trommel screen with perforated drum, central shaft and motor-gearbox drive on a steel frame

PT-TR Shafted trommel

Continuous sizing and scalping of bulk feed

A rotating drum, central shaft and drive arrangement form a continuous screening unit for sizing and scalping bulk feed.

Selection inputsLump size, aperture, stickiness and maintenance access.
SpecificationsOn request, after your feed data or sample are reviewed. Price on request.

Drum configuration and apertures are set from the feed and the target fractions.

Quartz sand grading trommel with cage-type rotating screen drum and drive on a galvanised frame

PT-TQ Quartz sand grading trommel

Separating quartz-sand fractions by aperture

A rotating screen drum separates quartz-sand fractions by aperture size, with separate undersize and oversize discharge.

Selection inputsTarget fractions, apertures, feed properties and throughput.
SpecificationsOn request, after your feed data or sample are reviewed. Price on request.

Fractions and apertures are confirmed against your sand and product targets.

Round stainless-steel vibratory screen on a blue vibrating base for fine screening of slurry

PT-VS Stainless-steel vibratory screen

Fine screening of slurries, powders and granules

Vibration moves feed across the screen for sizing, removal of oversize material and slurry filtration. Ceramic slurry, pigments, coatings and other fine-screening duties can be evaluated against the required screen mesh and deck arrangement.

Process roleRemove coarse particles or agglomerates and separate target size fractions.
ConfigurationUnit size, mesh, wetted materials and cleaning requirements.
Selection inputsFeed form, size, viscosity, corrosivity and throughput.
SpecificationsOn request, after your feed data or sample are reviewed. Price on request.

Contact materials, screen specifications and cleaning requirements are confirmed during selection. A screen does not remove iron: for iron-bearing impurities, a magnetic separator follows.
