Grocera Basalt
Basalt is a common “igneous volcanic rock” formed from the rapid cooling of Basaltic Lava that is low in silica content and comparatively rich in iron and magnesium. Basalt is usually Grey/Black in colour.
Cast Basalt
Cast Basalt is formed by “Melting and Recrystallizing” naturally occurring basalt rock. The controlled cooling of the molten Basalt Rock forms finely crystallized black glass ceramic of extreme hardness 8 on the moh scale.
Applications
Basalt is ideally suited to protect equipment where abrasive materials are conveyed, and cause sliding abrasion, such as pipes and bends for pneumatic or hydraulic systems, 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. 450°C. Resistant to chemicals and acids. Perfectly resistant to oxidation. Extremely smooth on the surface, and therefore has good sliding properties.
