Telsmith Vibrating Aggregate Screen 6 x 16 Triple Deck

Check for signs of oil breakdown

Measure temperature on the bearing housing face using a magnetic thermometer

Measure temperature on the bearing housing rim using a magnetic thermometer

Use a hand held digital heat scanning device to check for hot spots

Record the highest temperature reading from the bearing covers

Is any bearing cover temperature above 180°F (82°C)?

Check vibrator oil for impurities (oil sample)

Check nuts and bolts for tightness or missing fasteners

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 and replace if surface is worn below usable dimension

Check live frame for cracks or broken welds

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

Replace wire that exhibits any damage.

Observe operating screen for 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

Check that screen is tight against all buffer and crown bars.

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

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.

Clamp the brace being removed to the mounting tabs at both ends using a C-clamp.

Hold the hex nuts from below and remove all 3/4” capscrews holding the brace to the support frame.

Support the cross brace and remove the C-clamps from one end at a time while lowering the brace.

Select the type of brace to replace

Refer to Figure 8-55 for the correct brace pattern.

Align the new brace with the mounting tabs.

Secure the brace with 3/4” capscrews and toplock hex nuts.
