Cast Basalt Linings

KRAM Engineering (Pty) Ltd supply and install a wide range of Cast Basalt Tiles and Cylinders. Cast Basalt is formed by recrystallising naturally occcuring basalt rock and forms a finely crystalised glass ceramic of extreme hardness. It provides a resistant long lasting lining for static plant over which large volumes of abrasive or corrosive materials are passed.

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.


  • 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.
