Based in Great Blakenham near Ipswich, Suffolk, JT Few Plant Hire Ltd (JTFPH) is the latest company to invest in the new award winning Powerscreen TM Aggwash mobile wash plant.

Offering plant hire, road haulage and recycling services in Suffolk, JTFPH also supply bulk aggregates and other materials for use in the building and construction industries.

Washing for the first time.
Having only previously crushed and dry screened materials the company made the decision to invest in a wash plant which would enable them to add value to the material and provide quality materials to existing and new customers. Additionally, this investment would also allow them to process material previously untouched due to the high clay and high moisture content.

After almost 2 years of market research and subsequent site visits to view wash plants JTFPH made the decision to purchase the Powerscreen TMAggwash from industry leading, specialist washing equipment supplier DUO (Europe) plc. of Coventry, West Midlands. In addition to the supply of the Aggwash, DUO also designed, installed and commissioned a plant which included a full water treatment system based around a centrifuge which was specifically selected for its compact size, low operational cost and ease of maintenance.

The Installation and its Financial Benefits
Working within planning regulations (max 6 metres height) the water treatment solution supplied by DUO perfectly complements the Aggwash and provides a compact size plant relative to required production levels. As JTFPH had only previously crushed and dry screened materials it was essential that the incoming contaminated waste feed was dealt with in compliance with the Environmental Agency regulations which would not allow any waste water being sent to a lagoon.

To deal with this issue the DUO team specifically designed the water treatment element to incorporate a closed circuit system which not only guarantees the cleanliness of the product, reduces water usage, eliminates ingress into the ground and consequently promotes sustainability. The end result being that the centrifuge consistently produces an excellent cake, the low moisture content of which is vital to ensure that the material will be accepted by landfill sites.

The centrifuge is supported by a sludge tank, clarified water tank and a thickener system. All site water is collected and pumped into the plant to prevent any water going off site, with the silt from the centrifuge (20 tph of cake) being stockpiled for disposal off-site. This reduction in the volume of waste material has provided JTFPH with considerable savings on any landfill costs. The disposal cost of the material that does go to landfill is reduced further due to the cake's greatly reduced water content and consequently lower weight.

Fintan McKeever - DUO Director, commented, "The new plant is able to process a large variety of recycled materials and consistently produce quality aggregates. The very latest technology available, the Aggwash combines compact processing with excellent access and lower operation and maintenance costs than any other machine on the market."

A working partnership
Installed within a four week time frame the new plant is controlled by a fully interlocked PLC which runs the plant automatically. Processing recycled aggregates at 55 tph the Aggwash produces two sands, a gravel and washed oversize. Designed to process a large variety of recycled materials, the process efficiently removes metals, trash and clay from the feed material subsequently providing saleable materials for use in all building projects including concrete, drainage and pipe bedding.

Jonathan Few - Director, commented, "The new plant is exceeding our expectations and current processing requirements. It is proving to be an excellent investment that will provide us with more saleable products whilst promoting sustainability and we can feel secure in the fact that we have the benefit of the DUO team and all their expertise behind it."

Award Winning
