2. DESCRIPCIÓN GENERAL DEL PRODUCTO

Esta línea de productos abarca robustas, batch and continuoustype molinos de bolas engineered for the comminution of ores, clínker de cemento, y otros materiales duros. The operational workflow is based on proven rotary drum technology:

1. Cargando: Feed material is introduced into the rotating drum via a trunnion or peripheral inlet.
2. Molienda: The drum rotation lifts grinding media (bolas de acero), que caen en cascada e impactan el material, reduciéndolo a través del impacto y el desgaste.
3. Clasificación & Descargar: Ground material exits via discharge grates; particle size is controlled by retention time and often coupled with external classification circuits (p.ej., hidrociclones).

Ámbito de aplicación: Ideal para etapas de molienda secundaria y terciaria en minería. (cobre, oro, mineral de hierro), procesamiento de minerales, and cement production. Suitable for both wet and dry grinding processes.

Limitaciones: Less efficient for ultrafine grinding (<25 micrones) en comparación con molinos especializados como detritores de medios agitados. Performance is highly dependent on correct selection of media size, charge, and mill speed relative to the feed characteristics.
