Parnaby Cyclones design & supply a Skip Waste (fines) Washing Plant to
Midlands Reclamation and Waste Ltd
Parnaby Cyclones have been in the
business of supplying modular and mobile
washing plants for more than 50 years.
The business was founded by Derek Parnaby in 1973
and is still family owned and operated to this day with
three generations of the family actively involved with
the business.
“It is always a pleasure to meet and deal with other
family owned and operated businesses such as
Midlands Reclamation and Waste Ltd, based in
Stratford Upon Avon”. MRW is owned and operated by
Mr Michael Williamson and his son Joe Williamson.
“We started discussions with Michael quite a while
back with a view to supplying a skip waste (fines)
washing plant. Initially we were looking to supply a
Density Cyclone Separator system with a closed-circuit
effluent system including the Parnaby high-rate
thickener / clarifier vessel and the Parnaby multi roll
press belt press filter, whilst maintaining a compact
footprint.
The initial plant design duty was to handle 15-20 tph of
<15mm skip fines.
“Close to starting Michael’s project we discussed the
option to incorporate a coarse material washer module
to allow for handling up to 50mm particle size feed”.
Prior to completing the final plant design Parnaby’s
carried out test works to obtain the typical range of
size gradings and inerts / organics content.
This is invaluable for ensuring the right capacity is
designed with each section of the wash plant and
wastewater treatment circuit.
Following review of the test results, Michael asked for
the feed tonnage to be increased to 25-30 TPH to
produce the following products:
• 10 x 50mm coarse
fraction
• 4 x 10mm pea gravel
• <4mm sand
This is when the coarse
material washer was
introduced into the system.
The plant was
commissioned July of this
year, and it is fair to say
Michael and Joe are very
pleased with the overall
plant performance in terms of consistent throughput
circa 30 TPH and cleanliness of products.
“From Parnaby’s perspective we have been proud to
supply this wash plant to MRW. Michael and Joe have
been an absolute pleasure to work with and we wish
them every success with their business”.
