The In-Line Tru-Balance Sifter is a precision-built sifting machine used for finished product rebolt (re-sifting) applications, and designed for direct insertion in a pneumatic conveying line for the removal of a small amount of oversized impurities. It is usually constructed for floor mounting but can also be built to be suspended from a ceiling. No massive support foundations are required.

The machine is built to be easily opened for inspection, cleaning or maintenance. Nest-together sieve frames are stacked one on top of the other on the lower dome drive frame. 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 tie rods compress the stack of sieves between the upper and lower dome drive frames to create a pressure-tight unit. The drive frames are supported within a tubular frame and are connected to the drive components on the two ends of the machine.

The In-Line Tru-Balance Sifter uses standard T-frame 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 insures a smooth, balanced operation and minimizes building structural demands. The shake stays in the sifter!

Mechanically there are no gear boxes that can leak, no sifter knuckles to wear out.

Pneumatic sieve compression system used to elevate as well as lower the upper dome assembly provides:

• Rapid access for sifter inspection. The machine can be opened effortlessly in seconds enabling sieve removal for inspection, cleaning, or maintenance.
• No heavy domes to lift or hoist. The pneumatic cylinders elevate and support the upper dome while the machine is being serviced.
• Accelerated sifter closing. The pneumatic cylinders bring the upper dome down quickly enabling the desired compression of the sifter body to be achieved more rapidly.
