Location: Hadley Recycling and Waste Management Transfer
Station, Theale
Application: The Ore Sizer Primary Scalping Grid |
| The Ore Sizer Primary Scalping Grid was
demonstrated today at Hadley's Recycling & Waste Management based at Theale to representatives of the UK's construction
material waste recycling industry. |
|
|
|
 |
In the first demonstration the grid was used to
separate waste construction material of mixed size and
shape containing a high content of fines and topsoil.
The material was quickly and easily processed by tipping
directly onto the the grid by the bucket driver. It is
also possible to tip directly from the delivery vehicle |
|
|
|
| The Ore Sizer Primary Scalping Grid was
positioned by the bucket driver who was able to cleanly
pick it up from the delivery vehicle by using the bucket
edge. The grid is simplicity itself with no moving parts
or power requirements. |
 |
|
|
|
 |
The screened undersized product (-50mm) was deemed
ideal for use in backfill situations. After the
demonstration the grid bars were clean and ready for
re-use requiring no intervention from Hadley's support team. |
|
|
|
| The demonstration illustrated, how by using the Ore
Sizer primary scalping grid with the bars set in the 50mm
position, it is possible to completely bypass the primary
screening process, saving time, effort and costs producing
clean, oversized product ready for primary crushing. |
 |
|
|
|
 |
In the second demonstration the
bars were re-set at 100mm and used to separate low-grade,
mixed construction material from heavy clay soil, a
traditionally troublesome mixture requiring a great deal of
man/machine interaction by constantly having to clean out
power screens. |
|
|
|
| The Ore Sizer
Primary Scalping Grid succeeded in producing clean oversize ready for crushing.
The majority of the clay and topsoil passed through the grid
with little or no clogging between the bars. Any trapped
particles were quickly removed by flicking the bars by hand |
 |
|
|
|
 |
The graded backfill material
contained rubble particles up to 100mm. This material could
easily be further graded by resetting the bars to 50mm
(minimum setting) producing clean crushable material
50-100mm and finer backfill |
|
|
|
| Other models of the Ore Sizer Primary Scalping Grid are
available including a track-mounted version for use directly
at the extraction face, minimising product movement on site
and maximising efficiency. |
