Zircon Sand Processing Equipment

During dry processing it is crucial to avoid contamination by metal and even aluminium oxide which is used as wear protection for the air-separators and milling equipment. As nowadays comparatively affordable aluminium oxide mosaic plates or sintered parts are available as efficient wear protection of processing equipment, it is no longer such a problem to eliminate metal contamination.

The dry process in use today uses the closed circuit ball mill in conjunction with a high efficiency air classifier, which can directly produce grades up to D50 = 0.8μm average particle size.

Zircon Sand Grinding Plant

The zircon sand, typically at a feed size of below 200-300μm, is accurately metered to the ball mill, which is lined with aluminium oxide bricks and aluminium oxide grinding media in the form of cylpebs to grind the zircon sand.

The selection of the grinding media size mix is very important in order to achieve efficient results in terms of fineness and specific grinding energy. During this ultrafine grinding a lot of heat is generated, which must be kept at a level which the ball mill design and the glue of the aluminium oxide lining can tolerate.

Zircon Sand Processing Equipment

Key processing equipment used in the mineral sands industry includes screens, spiral separators, magnetic rolls and drums. The majority of equipment being delivered in the current industry is for use in wet concentrator plants.
