Metso HRC8 – Crusher with
sand crushing credentials
According to Metso – Finland’s global name in
the manufacture of crushers and screening
equipment – Industrial quality sand is a
threatened commodity.
In a recent press announcement promoting their HRC 8 (HPGR)
high pressure grinding rolls crusher, Metso stated: ‘With a
decline in the number of sand extraction sites in Europe – and
limitations in the number of permits for new ones – the supply
situation for sand has become challenging’.
‘With transportation of sand from distant locations declining
due to economic viability’, Metso is of the view that ‘local
production’ is the recommended alternative – a fall-back
whose time has truly come.
In this regard, Metso and their UK and Ireland distributor,
According to them, the HRC 8 offers a proven solution for
aggregate producers and contractors, delivering high quality
output with excellent gradation and particle shape, features
that McHale Director UK, Morgan Grant says: “fully meets the
specifications for recycled concrete and cement applications”.
“We have just completed the sale of the first Metso
Nordwheeler HRC8 into the UK. Eco-friendly, and fully
electrically driven and operated, the machine provides the
quality and reliability associated with Metso products in a
portable and user-friendly wheeled unit. Specified to crush
0/32mm down to a 0/2mm the machine has exceeded
expectations in terms of performance and reliability, achieving
20% more final product than originally anticipated,” he added.
Included in the Metso Plus offering, the HRC 8 for Aggregates
is available as a portable model on Nordwheeler as a part of
McHale Plant Sales share a common opinion, to wit that the
production of industrial sand, and the separation of usable
construction materials for cement and concrete production,
‘present significant business opportunities’ with the added
benefit of ‘addressing the rising demand for sustainable
practices’.
From its appearance at bauma 2025 - and the interest its
presence at the event generated - the HRC 8 (HPGR) high
pressure grinding rolls crusher occupies a niche position within
the pantheon of stone crushers, not least for its usefulness to
aggregates producers and contractors who themselves are
active in supporting sustainable operations.
Geared for the production of industrial sand, the HRC 8 offers
process flexibility and higher capacity coupled with low energy
and wear part consumption – attributes that make it an
attractive option for aggregates specialists.
According to Metso, ‘the cement industry creates 8% of global
CO2 emissions with a target to reduce these emissions by 25-
55% by 2030 and to achieve zero-emission cement production
by 2050’.
With the construction industry moving towards the circular
economy - and urbanization expected to drive demand for raw
materials to meet growing global needs – the use of recycled
materials in cement and concrete production is expected to
increase above current levels – an increase that Metso
calculates will be in 20-30% bracket.
Nordplant's pre-designed crushing modules and plants, and in
stationary format.
Providing flexibility for relocation based on material location,
the ‘energy efficient’ HRC 8 saves up to 50% energy compared
to other technologies, whilst generating low dust emissions
and noise levels.
Equipped to convert quarry and demolition waste into high-
quality, high-value sellable products – under the upcycling
acronym CDW (Construction and Demolition Waste).
Of particular note is its capacity to release recycled cement
from CDW to produce high-quality manufactured sand, and
improve poor-quality sand, thereby avoiding the use of virgin
resources and upcycling quarry waste materials.
As McHale sales director, Denis McGrath puts it: “given the
increasing number of high-profile businesses now supporting
the circular economy – including Metso and McHale Plant
Sales – the HRC 8 perfectly reflects the appeal it has for
manufacturers and distributors alike who are ‘on record’ as
supporters of the circular economy”.
