Search ÁRIDOS DE VILLACASTÍN welcomes you to its web space The ARVISA firm was created in 2004 with the aim of exploiting a large porphyry deposit in the municipality of Villacastín - Segovia. The Corneana mineral originates from contact metamorphism and is characterized by its great hardness and resistance to abrasion. Specifically, the exploitation consists of a massive, high-quality deposit with an average Los Angeles Wear value well below 12. It is an open pit mine, with benches of 12 m of average height. The crushing, grinding and classification plant was carried out entirely by METSO MINERALS ESPAÑA, SA The main elements of the plant are a large jaw crusher, four cone mills, four screens and 22 conveyor belts. The main applications of the aggregate produced by ARVISA are as BALAST for both Conventional and High Speed Railways, as well as sub-ballast, bases and sub-bases for railway infrastructures, aggregates for asphalt agglomerate, aggregates for concrete and precast concrete; we also produce gravel, breakwater, materials for layer of shape and selected soil, etc ... ARVISAIt has stockpiles for all the applications described and the plant's large production capacity of 700 Tm / h ensures continuity in the supply of any of the materials offered, even in times of high demand. The granulometries of the aggregate produced by ARVISA are: 0/4 mm, 0/6 mm, 4/6 mm, 6/12 mm, 12/20 mm, 20/32 mm, 32/56 mm and ballast. The ballast is Certified by ADIF as TYPE 1 BALLAST - High Speed. The aggregates produced have the CE Marking and the production process is ISO 9001 certified. Currently, ARVISA is in the process of implementing ISO 14001. The farm has its own laboratory with which the most important parameters of each of the products that are produced are continuously determined. In this way, any deviations that occur can be corrected immediately and the quality of the entire production is adjusted to the maximum. Specifically, in the internal laboratory, the granulometric and plasticity tests are carried out - Atterberg Limits, Sand Equivalent, Slab Index, Cleaning Coefficient, Los Angeles Wear, etc. Tests are also carried out periodically in recognized external laboratories in order to contrast with the results of the internal laboratory as well as to obtain other parameters of certain interest such as the Accelerated Polishing Coefficient and all the physicochemical tests. In this way, ARVISA can ensure the highest quality throughout the production process. The company is in a strategic location: at the crossroads between the N-110, the AP6 and the N-VI, which allows supplying Madrid, Segovia, Ávila, Valladolid, Salamanca and Zamora in a very short time and effective way.
