Our transportation and loading machinery, frontal loading shovels, backhoes and dumpers, capable of carrying up to 50 tonnes per trip, provide the raw material needed by the production plants. The stone is then crushed to different sizes and selected.
Once classified, these materials can be distributed directly to our clients or sent to other crushers for the production of materials of a smaller diameter (sands of different sizes and Belfiller 63 µm -calcium carbonate-). After this process, the product is classified for selling.
We also sell materials for rockfill or other aggregates, as well as a sterile subproduct, which results from the pre-sieving process done to rod the stone of impurities. Canteras La Belonga does not produce any kind of dangerous spills or polluting waste.
It is important to mention the composition and quality of the sands and micronized products, due to their resistance and homogeneity, in the manufacture of mortars, concretes or asphalt agglomerates, as well as placing on the market the Belfiller 63 µm, calcium carbonate >98% purity, finely milled (maximum size 63 µm) for different uses such as construction, industry, environmnent (removing sulfur from combustion gases, wastewater…), agriculture (fertilizer, corrector of soil acidity…)
