Gravity Flow | Quality Assurance Sifters
- - - - Operation - - - -
Usually constructed for floor mounting with a top inlet and top discharge, custom configurations for downward directed discharges and multiple floor layouts are easily accommodated. An important benefit of the reliable Tru-Balance drive is that no massive foundation is required.
Its compact, space saving design with light weight components enable the sifter to be easily dismantled for inspection, maintenance or cleaning. The sieve rings and screen trays nest-together and are stacked one on top of the other on the lower dome. The number of sieves required is based on the product, conveying rate and sieve mesh size for each application.
A pneumatic sieve compression system and draw rods compress the stack of sieves between the upper and lower domes and create an air-tight unit. The upper and lower domes are connected to the drive components which are supported on the two sides within a tubular frame.
The In-Line Tru-Balance Sifter uses standard motors and V-belts to turn the two counterweights positioned on the left and right sides of the machine. These weights straddle the machine's center of gravity and counterbalance the mass of the rotating sifter housing. This unique drive mechanism invented by Great Western ensures a smooth, balanced operation and minimizes building structural demands. The shake stays in the sifter! Mechanically, there are no gear boxes that can leak, and no sifter knuckles to wear out. Click here to see our Tru-Balance drive video.
