Ore ball mill sometimes called ore grinding mill, is generally used in mineral processing concentrator, processing materials include iron ore, copper ore, gold ore, molybdenum ore and all kinds of nonferrous metal ore.The core function of the ore ball mill is to grind the materials, and also to separate and screen different mineral materials, and to separate the tailings, which is very.
Conventional ball milling is a traditional powder-processing technique, which is mainly used for reducing particle sizes and for the mixing of different materials. The technique is widely used in mineral, pharmaceutical, and ceramic industries, as well as scientific laboratories.
Ball mills give a controlled final grind and produce flotation feed of a uniform size. Ball mills tumble iron or steel balls with the ore. The balls are initially 5–10 cm diameter but gradually wear away as grinding of the ore proceeds. The feed to ball mills (dry basis) is typically 75 vol.- ore and 25 steel.
Changing ball m ill performance and can be labelled as an event which characterizes the ball mill behaviour. Therefore, these responses are subject to time series event classification.
According to the principle of superfine ball milling classification, through redesigning and arranging the traditional ball mill lining plate, grinding body and discharge device, the ordinary ball mill is upgraded to superfine ball mill, and then combined with the Special Superfine Classifier to form a closed-circuit system, which can superfine grind the steel slag, slag, fly ash.
