PD bucket solves PFA recycling problem

Digger Blogger | 10:07, Thu March 30 2017

A PD screening bucket has solved a problem for a customer needing to process pulverised fuel ash (PFA) at a power station.

For more than 40 years PFA from the power station has been sent to landfill.  As the material is very fine it needs 12-14% of moisture adding to it so it doesn’t blow away.  This means it is conditioned with water to stay on the floor.

Logistics firm Hargreaves Services, whose roots are in the coal industry, wanted to recycle some of the landfilled PFA.  The material it wanted to process was nine years old so had settled firmly into place.  They had started reclaiming the old PFA and bulldozing it up.  This unfortunately meant that much of it was in big boulders of 10-20mm in size.  They needed it shredded down to 15mm for the use they had planned for it.

As a regular customer of Worsley Plant, Hargreaves looked at hiring a Remu screening bucket for their customer but it wasn’t up to the job.  They needed something specialist.  Therefore, Remu stepped in to build them a standalone version of their new PD bucket, which was launched to the UK market at Hillhead 2016.

Typically the PD3160 is specially designed and manufactured with most durable materials and up to date engineering in screening buckets technology to fulfil requirements and overcome challenges of pipeline projects, trench backfilling and other demanding heavy duty applications.

The new PD3160 padding bucket is designed and built for heavy-duty padding work in harsh conditions, for use with 30-40 tonne excavators.

The PD bucket worked well, processing the PFA down to under 15mm, which through further production processes was then formed into round pellets, which create lightweight aggregate to sell to the building trade.

Hargreaves said:  “Worsley Plant surpassed our expectations by working closely with us to ensure we had a happy customer who could achieve his goals with recycling materials that were otherwise being unused. They went the extra mile to work with Remu and produce a bucket with special blades [pictured above] that would allow the material to be processed to our needs.”
