Canteras La Belonga S.A. has nowadays two independent groups of grinding, equiped with a primary crusher patent Larón of 1000 tn/h grinding capacity and several secondary crushers to manufacture the different granulometric fractions of  our marketed products.

The primary crushed triturates stone in variuos sizes which are selected by four vibrating screens. In a second phase, the sorted materials can be distributed to customers other be sent to secondary crushers to increase production with finer granulometry materials. Thicker materials are sent to a pre-stock, supplying a second installation equiped with two sand mills more and a capacity of 300 tn/h.

Regarding our clients’ needs, we have two centrifugal separators which remove excess fine sands and three compact sand groups responsible for the production of fine sands which are intended for the manufacture of mortars and other industrial products (natural calcium carbonated in several sizes, 0,5mm, 1,3 mm, granulates…)
