The transportation of a fully choked large feed chute will exert one of the largest floor loads in a modern processing plant.  The new RUSSELL Multi Wheel Feed Chute Transporter significantly reduces the floor load by increasing the number of wheels and introducing load distribution technology.  The potential savings in floor costs are enormous.

Mills installed in concentrator plants have increased rapidly in size.  As a result, the volume and potential fully choked feed chute weight has increased dramatically.  Feed chute removal is a critical task in mill maintenance, which is best facilitated through the use of a feed chute transporter.  While the feed chute transporter allows freedom to move the feed chute over a large floor area, the transporter often imposes the highest moving point loads on the mill floor.  Consequently the loads imposed by the feed chute transporter become the dominating factor in mill floor design.  The problem is amplified due to the centre of gravity bias of the feed chute towards the mill trunnion, resulting in the majority of the chute load being carried by the two wheels closest to the mill.

In response to this, RME has recognised the substantial savings that can be realised in plant design by reducing the floor point load imposed by the feed chute transporter device.

The RME Multi Wheel Feed Chute Transporters can be selected to find the most economic solution for the floor capacity of each concentrator plant.  RME's range (capable of bearing specified load tonnages) of multi wheeled transporters reduce the floor load to within economic floor load limits by:

• Providing the ability to reposition the feed chute anywhere while maintaining a relatively low and even distribution of floor load
• Utilising an increased number of independently supported wheels that distribute the load evenly without the need for a perfectly flat floor
• Supporting the feed chute more centrally, and as such, maintaining an even wheel load across all wheels.

They also offer the advantage of a reduced clearance width due to compact design, as the transporter wheels are mounted directly under main load support beams rather than beside the beam.

The table below lists the floor loads of the available selections of Multi Wheel Feed Chute Transporters in comparison with the floor loads of the standard four wheel forward bias design.
