Trommel manufacturer utilises Baldor bearings

One of the major features of the stone-cleaning and sizing machine is deployment flexibility, due to the design's incorporation of a low loader trailer.

Aside from deployment flexibility, one of Stelex's key design parameters for the trommel was ease of on-site maintenance.

The company therefore chose to standardise on Dodge Imperial ISN bearings for all of the machine's main rotational load-bearing parts.

These bearings use a patented thin-wall push-pull adapter system, which can be either metric or imperial sizes and achieves clearance setting without the use of feeler gauges; the bearing can be installed or uninstalled simply by turning a locknut clockwise or anticlockwise.

Dodge Imperial ISN bearings can be installed and uninstalled in less than 15 minutes.

They can be fitted without specialist tools and are supplied pre-lubricated and fully sealed, making them suitable for on-site maintenance purposes.

Stelex currently uses eight 90mm Dodge Imperial ISN bearings - which are contained in ISN pillow blocks - on the HT182M, but the company is also looking at using the 140mm models on larger trommels in development.

The HT182M road-going trommel is suitable for cleaning and sizing quarried stone, regardless of location.

The machine's integrated low loader trailer enables it to be driven to the exact point of need on site.

It is capable of handling blasted, ripped or as-dug material and can process up to 500 tonnes/hour.

Typical applications include quarry overburden cleanup and the removal of fines prior to crushing.

The trommel's main components are a 42-tonne capacity feed hopper equipped with a variable speed reciprocating tray feeder and a 1.8m-diameter x 9.8m-long screening barrel.

The barrel sits on hydraulically driven support rollers - the main drive pump can be powered by an electric motor or a diesel engine - and its rotational speed can be varied to accommodate different material-flow rates.

The complete machine sits on support legs or an under-frame and the desired grade of material is obtained via an extraction hopper placed beneath the appropriate section of the screening barrel.
