Stone basalt cast

Description

CAST BASALT is the best material for the industrial factories which face the problem of an abrasive wear, affecting of severe atmospheres and elevated temperatures to the equipment and constructions used in their production process. CAST BASALT falls into 8th group of mineralogical hardness (т.е actually concedes only to diamond and emery by this parameter) and consequently, its wearing quality considerably exceeds all steels, including the manganese steel, cast iron (incl. IChKh grade), rubbers, plastics and all the rest.

Rectangular and hexagonal tiles are used in the coating of large areas like bunker, silos and tank.

Typical applications

Basalt is ideally suited to protect equipment where abrasive materials are conveyed and cause sliding abrasion such as in pipes and bends for pneumatic or hydraulic systems, in cyclones and seperators, in flumes and chain conveyors, in hoppers and silos, mixers, tanks, pulpers, etc.

Advantages:

• Resistant to friction-induced abrasion
• Heat resistant up to approx. 620 K (approx. 350 °C)
• Resistant to many chemicals and acids
• Perfectly resistant to oxidation
• Extremely smooth on the surface, and therefore has good sliding properties

What is Cast Basalt?

Naturally occuring basalt rock is quarried, melted, cast and annealed to form a finely crystallised glass, ceramic of extreme hardness (8.5 on the moh scale)

What is it for?

Basalt provides a long lasting lining for static plant over which large volumes or abrasive and/or corrosive materials are passed.

How is it fixed?

Basalt tiles can be bedded and joined in cement or special bonding agents. The agents chosen depend on the application. Tiles can be supplied with a counter sunk central hole for individual bolting onto or in ready-made liner plates and pipes.

Where is it used?

Basalt can resist wear, corrosion and temperatures up to approximately 400 °C; Cast Basalt is generally used in wet material handling situations such as coal chutes and ash sluceways, ash pipelines at power stations and hydraulic granulated slag or sand conveying services . Basalt should be used in light impact areas. If you are in doubt let our sales engineer advise you on an “impact friendly” design.

Application

Other than automobiles, some of the other industries where these are used in include:

• Power
• Coal
• Steel
• Cement
• Pulp & Paper
• Mineral Processing

Cast basalt tiles is mainly used in thermal power plants, steel mills, mines and other parts with heavy wear, such as raw coal bunkers, mine bins, coal unloading trenches, hoppers, ore troughs, flotation machines, chutes and other parts.

• Round coal bunker lining: ultra-thin cast slate 14-20mm thick;
• Coal discharge ditch lining: commonly used 25-30mm thick cast slate;

Coal drop bucket lining

lined with cast slate, generally 25-30mm (high chromium steel is best used for coal drop points);
