TROMMEL APPARATUS

Product Description

Specification:

TROMMELAPPARATUS

Trommel or revolving screens consistsof a cylindrical screen rotated about its axis. Simple Trommel may be arrangedin series with oversize of the first passing to the second Trommel and theoversize of the second passing to the third, etc.

They are quite efficient for coarsesizes. The inclination of Trommel varies depending on the nature of material tobe processed. The present Trommel is built with screens of different sizesthroughout their length, the feed entering at the end of the finest screen. Inthis way it is possible to collect materials of different size range from asingle Trommel.

Drive to the central shaft is giventhrough a variable speed motor coupled to reduction gearbox.

Drive is provided for conducting theexperiment at varying speed. Set-up is complete in all respect with guards,bins and control panel. A special arrangement to change the angle ofinclination of the Trommel is made.

Experimentation/learning objectives:

To calculate the separationefficiency.

To study the effect of speed onseparation efficiency.

To study the effect of changing theangle of inclination and RPM
