Rocklabs’ Smart Geo-Prep is an automated version of the very
successful Boyd – RSD Combo. The automation is provided by an easy to use PLC.
When using Smart Geo-Prep the operator chooses an optimum weight for the split
that will be produced. For example, when using a ring or puck mill, there is an
optimum amount for pulverising, not too high a weight so the sample is
pulverised fully, not too small a weight so the pulverised sample is
representative of the original material.
The operator weighs each sample (this can be recorded in a LIM System) and loads
it into the Boyd Crusher. The sample material falls into a small belt conveyor
that takes it to the RSD.
The speed of the belt is controlled by a PLC so that small samples travel slowly,
to ensure a high quality split through the RSD. The RSD is controlled by the PLC
to provide the pre-set weigh plus the remainder. The remainder can be retained
or dumped. If dumped, it can be removed by a second belt conveyor to a bin or
outside the building.
