SOTECMA fabrica equipos para el procesamiento de minerales, destinados a minerales industriales, la industria auxiliar de la construcción, la minería metálica y otros sectores, tanto para procesos por vía seca como por vía húmeda.

Disponemos de equipos basados en tecnología vibratoria, como alimentadores, cribas y escurridores, así como de equipos para el lavado de arenas y el tratamiento de aguas de proceso.

Asimismo, suministramos equipos para procesos de clasificación, molienda y cribado, además de soluciones para separación gravimétrica, separación magnética y clasificación granulométrica. También desarrollamos procesos completos e instalaciones llave en mano adaptadas a las necesidades de cada proyecto.

Reducing the size of minerals by crushing or grinding is a fundamental stage in most mineral processing operations. Depending on the process, this operation may serve different purposes:

• Reducing the particle size to suit the next stage of the process. For example, if a grinding mill can only accept material with a maximum size of 20 mm, a crusher must first be installed to reduce the feed material below this size, ensuring continuous and efficient feeding of the mill.
• Producing the particle size distribution required for the final product. In many applications, particle size is a key specification of the finished product. A typical example is concrete production, where a controlled blend of different aggregate size fractions is required, such as:
  • Sand: 0–4 mm.
  • Fine gravel: 4–12 mm.
  • Gravel: 12–25 mm.

In this type of process, the stone crusher is usually installed in one of the final production stages. Its function is to reduce all the material to a size below 25 mm, preparing it for the final screening stage and the production of the required aggregate size fractions.

SOTECMA can supply all types of crushers and grinding mills, selected and sized according to the specific requirements of each stage of the mineral size reduction process.

The following factors, among others, are taken into account:

• Maximum feed size of the material entering the crusher or mill.
• Required product size after the crushing or grinding stage.
• Mineral throughput to be processed.
• Physical properties of the material, such as hardness, abrasiveness, moisture content and other characteristics that determine equipment selection.
