Aggregate Industries UK Ltd operate a quarry process at Ivonbrook Quarry under section 3.5 of the Environmental Permitting Regulations. The quarry is located near Grangemill.
Ivonbrook Quarry previously operated a road stone coating plant alongside the limestone quarry, but this ceased to operate during 2009. Quarried rock is screened and then processed through a primary crusher, secondary crusher and then on to the screen house or to the Limestone Fines Milling Plant. Final screened products are stockpiled or stored in bins prior to loading into lorries for onward dispatch. Products from the Milling Plant are stored in silos or in a covered stocking area prior to sale.
