Design :

A horizontal over hung sieve drum
rotates in an enclosed casing. This
drum is made of preforted sheet metal
and is kept open by brush With plug
geared motor, Without rotary diving members.

Use of DRUM SIEVE :

As a pre-cleaning machine the drum sieve is very versatile and it is used above all in the intake section of granular and floury bulk material in flour mills, silos and other factories in the food provender and chemical industries.It serves to seperate coarse impurities, such as straw particles string, paper,pieces of wood, mare leaves and cobs etc.. In order to releve downstream machines and conveyors and to protect them against opreating faults and damage, moreover it is suitable for performing certain leaning operations.

Method of operation :

The product is a fed via the iniate spout in to the interior of the drum and is revolved so that the fines drop through the sieve, whereas the rolling motion causes the coarses impurities to move the outlet channel below the inlet. The guide spiral located in front of the outlet assists discharge of the coarse impurities and prevents the inclusions of fines.
