Aggregates 4-30
Limestone lump graded 4-30 mm
Limestone lumps of 4-30 mm are produced by quarrying followed by crushing and sorting to the required fraction.
Area Of Use
We supply limestone in 4-30 mm chunks as a product of desulphurisation in power generation. The lump limestone is further processed at the power station for final use in combustion processes.
