Powerpack

Features

Free standing remote from main trommel for ease of maintenance rated up to 154 HP, mains or diesel powered. Direct drive hydraulic pumps from diesel engine or electric motors provide power to the all new live drive fully hydraulic screen drum support rollers and the inline hydraulically controlled heavy duty plate feed table. Hydraulic valve settings increase and decrease rotation of drum and stroke of feeder to insure the best possible tonnage and cleaning of contaminated materials at all time. Skid mounted or containerised, electric or diesel power units are available.

Control features for safe working include

• High temperature oil cut off
• Low oil level cut off
• Hydraulic high presser off load
• Weather proofed control panels
• Emergency stop buttons and warning lights

Drive Support Rollers

Cast steel support rollers

Cast steel support rollers are fitted to all of our new range of trommels and comes complete with hydraulic gear motors which provide power to the heavy duty rotary screen drum, all rollers are fully adjustable and low maintenance

Heavy duty cast steel rollers

Heavy duty cast steel rollers support the centre or end screens segments on its machined roller paths, all rollers are fully adjustable to ensure maximum contact and smooth rotation at all times.

Machined thrust rollers

Machined thrust rollers with sealed bearings are mounted at the feed or discharge end of the drum to aid the tracking and floating of the screen when trommel is in full production.

Screen Segments

Features

All screen segments and aperture sizes are made to customer specification. The diameter of the bars and thickness of the support rings are determined by the openings of the screen segments apertures. Machine roller paths are bolted between segments to support the overall length of the drum and insure smooth rotation. All screen segments are stress relieved to prevent premature failure. All segments are made from high quality steel, fully welded robust construction to withstand the high volume tonnage tumbling through the segments.

Specifications

Diameter: 5′ – 7′ 6″ (1.5 – 2.3 m)
Length: 6.5′ – 39′ (2 – 12 m)
Aperture: 1.5 – 36″ (38 – 902 mm)

Feed Plate Table

Fully lined with Hardox 400 wear plate to side deflectors, lower feed pan and feed plate table pan and plate feeder table. Feed table is supported by heavy duty inline rollers with low maintenance sealed for life bearings, all rollers are fully adjustable in order to maintain contact with the machined roller paths on the tray table at all times. Two 6″ bore hydraulic rams power the feed tables forward and backwards movement, complete with electrical limit switches. Feed table stroke is fully adjustable to suit tonnage requirement and type of materials to be screened.

Feed Hopper - Static Trommels

Construction

¾″ (19 mm) mild steel plate of robust welded construction, heavily ribbed with roll steel sections and plates. The feed hopper is located directly on to the mainframe feed end box.

Liner plates

Hardox 400 liner plate ¾″ (19 mm) thick can be bolted to the inside of the hopper to stop premature wear. Hopper is designed in three complete welded modules which are bolted together to withstand the day to day abuse of site dump trucks tipping material at a rate of 500 – 1000 tonnes per hour.

Specifications

Feed hopper capacity with hopper extensions

500 tonne per hour unit: 85 tonnes
1000 tonne per hour unit: 150 tonnes

Standard feed hopper capacity

500 tonne per hour unit: 38 tonnes
1000 tonne per hour unit: 68 tonnes

Feed Hopper - Mobile Trommels

Features

42 tonne feed hopper module with drop side extensions and twin hydraulic ram plate feed table.

Construction

⅝″ (15 mm) Hardox steel wear plate of robust welded construction, heavily ribbed and reinforced steel sections and plates.

Hopper and Feed Module

The feed hopper is located directly on to the rear mainframe complete with twin hydraulic rams which powers the feed tables forward and backward movements which are controlled by electrical limit switches, this ensures the smooth transition of material from the hopper to the screening barrel. Feed table stroke is fully adjustable to suit tonnage requirement and type of materials to be screened.

Liner plates

Hardox 400 liner plate, ⅝″ (15 mm) thick, is bolted to the top and sides of the feed table to stop premature wear.

Support Rollers

Feed table is supported by heavy duty inline rollers with low maintenance sealed for life bearings, all rollers are fully adjustable in order to maintain contact with the machined roller paths on the tray table at all times.

Hopper Maintenance

For ease of service, the hopper and feed table are built as one module and can easily be disconnected from the main chassis in order to carry out maintenance.
