Nigel’s HJB Vision
For over 40 years Nigel has been a part of the family business and it’s been one of his driving ambitions to make plant last as long as possible, carefully evaluating the best possible processes when dealing with the extraction and usages of aggregate. As aggregate is not in abundance on the Island, HJB have been developing many different second life procedures to meet the local needs making sustainability a common thread throughout.
This has led them re think re-usage in a big way and making sure that where possible alternative and recycling is at the fore, for example over the past twenty years their investment in plant recycling has saved a substantial amount:

The Story ....
Crusher Mark I
Nigel started recycling various pieces of plant in the 1990s in that year he built his first stone Crusher for use on the beach at Bembridge. This was fabricated from a 1948 scraped rotary impact crusher being an old Parker Cubit 3 recovered from Frome in Somerset, the steel for the crusher’s frame came from one of JS Whites old dockside cranes similar to that of the Hammerhead on the west bank of the Medina.

The engine was a ford engine from a redundant roadside compressor, there was no conveyor fitted to this particular crusher as the exit for the material was a vertical drop strait through. Twenty years later it was sadly retired due to lack of spares being available for either the engine or crusher.

Crusher Mark II
The base unit was again a scrapped Parker 102 from a scrap yard near Doncaster, a friend of Nigel happened to spot it and suggest that Nigel could make use of it. It was then purchased and brought back to the Isle of Wight as a part load by George Jenkins Transport. The engine to drive the crusher was a redundant air compressor from Valvona’s scrap yard in Oakfield Ryde. The steel to construct the chassis came from Bartlett’s Garage in Newchurch . The tyres, wheels and axel came again from George Jenkins Transport. The unit took around a month to construct and is now based at the HJ Bennett Blackwater Recycling Plant. The feed Conveyor to Crusher Mk II was given to HJ Bennett by Bardon Vectis as it had reached end of life as they saw it. However, Nigel saw the potential and refurbished the unit including a full shot blast and re-paint.

Crusher Mark III
To build a crusher as cheap as possible with limited funding for the crushing of stone operation at Bembridge beach.
The engine was a disused cement tanker; and yet again the rotary impacter was a old Parker 102 crushing unit from New Milton Sand and Gravel scrap heap. The main girders for the Chassis were extracted from the old Woodnuts boat yard at Bembridge Harbour, which during WWII had made Motor Torpedo Boats for the Royal Navy. Once again the tyres and axels were found on George Jenkins scrap heap and the conveyor was salvaged from the old Island Plastics factory at Edward Street in Ryde.

Grader Mk 1
A grader made in 1990 is still in operation today at HJ Bennett’s recycling depot at St Georges down IOW. Various parts were cannibalised from a variety of buildings along with steel from the water works and the engine was again a Southern Water redundant part.
New £ 77,000.00

Carbon Savings
With all of these recycling projects if the parts had not been used the metals would have had to be taken to the relative smelting plants to be melted into steel, thus a carbon footprint saving on both transport and the energy used to process into reusable materials.
