Conveyor Drives – Coal Powered Electricity Generator

Conveyor Drives – Coal Powered Electricity Generator

The Challenge: Retrofitting an old structure, in an aggressive environment, to a tight schedule The 1600MW power station we are visiting for this case study was located at the coal mine site in the Latrobe Valley in Victoria. Two duel drive conveyors had been in use since 1987, situated on a travelling stacker in the mine and conveying coal from the mine to the power station. The drive units needed to be replaced without any modification to the existing structure, while still achieving an increase in power and improvements to the brakes. The replacement also needed to occur on a […]

Screw Conveyor Application – Live Bottom Bin

Screw Conveyor Application – Live Bottom Bin

The Challenge: Size Restriction A ´live bottom bin´ is used to transfer large amounts of material that are generally difficult to convey, and are especially suited for applications where there is a limited working area. They consist of multiple screw feeders arranged in parallel configuration across the floor of the bin; the unit completes two functions by both storing and transferring the material. In this case study, we visit a clean coal technology plant, which required a live bottom bin to be installed into an extremely dimensionally restricted room. Brevini was required to supply the motors and gear units to […]

Bucket Elevator – On Board Ship

Bucket Elevator – On Board Ship

The Challenge: Space Restriction, Aggressive Environment, High Axial & Radial Loads A ship that transported gypsum required a new solution for their bucket elevator. Previous gear units were leaking oil, due to the gypsum environment degrading the output seals. In addition, bolts were ´popping´ due to the high axial and radial loads being experienced. A solution was proving difficult, especially given the small envelope size required. The Solution: Brevini´s S-Series Gear Unit, plus In House Local Engineering Design. First, Brevini´s design engineers visited the ship and completely measured the available space. They then produced a customised design to meet the […]

Winder Drive – Coal Mine

Winder Drive – Coal Mine

The Challenge: High torque, Large Speed Variations, High Safety Margins A winder drive is designed to operate a lift or elevator in an underground mine. In this case study, we are visiting a coal mine in eastern New South Wales in the process of replacing an old personnel & equipment elevator. This elevator transports large loads over long distances, up and down the mine shaft, and is subject to stringent safety requirements. In addition, the unit is required to operate at two significantly different speeds. People are transported at high speeds; equipment is transported at 1/3rd of that speed. The […]

Refurbishing a Large Double Drum Shaft Sink Kibble Winch

Refurbishing a Large Double Drum Shaft Sink Kibble Winch

The Challenge: refurbishing large winches within tight schedule Brevini Australia was requested to provide a solution for a large double drum shaft sink kibble winch. The winch had two drums each powered by 600kW motors that could be “clutched-in” together to provide 1200 kW to one drum with a peak power of 2600 kW. The motors were back to back with a rear non-drive end shaft extension with and electromagnetic clutch that could combine the power. The winch drums were running parallel to the motors and the method used to reduce the speed and increase the torque was to employ […]

Conveyor Drives – Recycling Centre

Conveyor Drives – Recycling Centre

The Challenge: Gear units with high efficiency, wide ratio range, flexible mount What is arguably the largest combined recycling and landfill site in the Southern Hemisphere, the Genesis Xerowastefacility was looking to manage waste with a system of 49 conveyors. Looking for a complete drive solution for the site, Genesis Xerowaste wanted gear drives that were extremely efficient, with flexible mounting choices, wide range of ratios and also of a compact design, as space was a strong consideration, as well. The Solution: PIV Posiplan BPH Series bevel input and helical output gears, with planetary intermediate stage Brevini suggested a revolutionary […]
