For over 40 years, Wear Solutions has offered a comprehensive range of abrasion- and corrosion-resistant lining products to combat erosion in bulk materials-handling in heavy industry. Ceramic-based materials such as Basalt, Alumina and SiTech are the most well-known lining materials used. Cast Basalt is formed from Volcanic rock that is crushed, cast, and annealed in a specialised process. This results in two exceptional qualities. Firstly, being many times higher in resistance to erosion than iron or steel and, secondly, it has a high degree of chemical resistance.
It can be cast in a variety of shapes using sand moulds or spun into 500-mm-long cylindrical liners. Certain diameters are now available at 1000 mm. Spun liners are available in diameters between 100 mm and 660 mm, with engineered tile sets available for sizes above 660mm. When first installed, cast Basalt has a coefficient of friction similar to that of steel, and a density of around 3000 kg/m3. Over time the conveyed media effectively polishes the surface of the Basalt lining, improving the coefficient of friction as the linings are used.
Cast Basalt can be used for the lining of pipework, chutes, bunkers, cyclones, and hoppers. It has become the global standard in areas such as ash slurry pipework, often used at fossil-fuel power stations. It is an all-round cost-effective and adaptable lining material that extends the life of equipment in pipe or tile form were affected by abrasion.
Cast Basalt is well-proven in a variety of industries as a cost-effective, long-lasting lining material used to extend the operating life of equipment manufactured or lined with lower-wearing materials such as steel, cast iron, rubber, and polyurethane. HMA Wear Solutions cast Basalt lined pipe offers extraordinary abrasion resistance to most acids and alkalis. Its manufacture is a specialised process, with HMA Wear Solutions having developed unique in-house techniques. As a result, HMA Wear Solutions cast Basalt has been widely adopted throughout the industry as the leading product for abrasive slurry and pneumatic product transfer applications.
