Telsmith Vibrating Aggregate Screen 6 x 20 Single Deck

Remove the breather assembly from the top of the bearing housing by unthreading the complete assembly at the threaded bushing.

Separate the breather cover from the mounting bushing by unscrewing the cover from the bushing.

Clean the assembly with solvent.

Blow dry the assembly with compressed air.

Were blockages removed successfully?

Replace the breather with a new unit if blockages cannot be removed.

Check wire weave for breaks, tears or separation of the wire.

Replace wire that exhibits any damage.

Are there any panels with 'dead spots' where material is puddling?

Replace wire panels that no longer maintain tension over the complete surface area.

Screen Tension and Buffer Check

Is the screen tight against all buffer and crown bars?

Replace rubber if missing, torn or worn through to the metal on crown bars.

Ensure cross bracing is provided if all support frames and drive unit/shaft casings are removed.

Determine sequence of wire support frame removal based on screen model and drive unit/shaft casing status.

Remove all cross braces from the bottom side of the screen frame.

Support the back plate with a hoist and lift straps, then remove and lower it.

Support the discharge lip with straps and a hoist, then remove and lower it.

Support the wire frame from above with lift straps at all four corners.

Cut the huck bolts at the four corners and temporarily replace them with bolts, nuts, and washers.

Consult Telsmith Engineering Department before proceeding with shim changes

Remove the two hex head capscrews holding the counterweight shim stack

Slide the shims out one at a time off the counterweight hub

Slide additional shims on the counterweight hub if required

Fasten shims in position with the two hex head capscrews

Check vibrator oil for impurities (oil sample)

Check nuts and bolts for tightness or missing fasteners

Check decks for heavily worn hardware or worn cross members

Check that vibrating unit drive sheave is free of debris and tight on shaft bushing

Check that electric drive motor output sheave is tight on shaft

Component Inspection and Replacement

Inspect friction pucks. Replace if surface is worn below usable dimension

Check live frame for cracks or broken welds
