Coal Processing

Rotary Coal Breaker
Double Roll Crusher

The preparation of ROM coal commences the moment it is received from the mine. The Rotary Coal Breaker crushes and breaks the coal and removes the majority of the rock contamination.

The sized coal from the Rotary Breaker can then be fed into a Rolling Ring Crusher which produces a finer product.

For more specific and smaller sizing of the coal, the Double Roll Crusher is generally the preferred machine, particularly for processing the sizes required by power stations and for the export market where tight specifications are required.

Serving the South African coal market for more than 80 years, Osborn’s Coal Crushers have proven to be extremely reliable and have gained popularity as far afield as Australia, Turkey and neighbouring African countries, such as Zambia, Zimbabwe, Botswana and Mozambique.

Mineral Sizers

Astec’s range of single shaft and twin shaft roll sizers are rugged by design and engineered to handle high tonnage throughput using minimal installed primary power. The mineral sizers can be configured to operate in two ways depending on the material output size required.

Horizontal Shaft Impact Crushers

Impact crushers may be applied as primary or secondary crushers in applications processing soft, low abrasion materials.

Double Roll Crushers

Equipped with adjustable clearance between the rolls, double roll crushers are typically applied where greater control over product sizing is desired. Larger models are capable of accepting 600 mm (23.6”) feed.

American Roller Ring Crushers

Well suited for most coal crushing applications requiring a top size output from 12 mm to 38 mm (.47” x 1.5”). Larger models are capable of accepting feed particles as large as 600 mm (24”). Available in sizes that range from 30 HP.

Rotary Coal Breakers

Rotary coal breakers are typically utilized for the primary breaking and cleaning of run of mine coal. An assortment of lifters and plows are installed in various arrangements to control flow rates for optimum efficiency.
