Coal mine scraper liner with cast stone plate

Cast basalt is a type of volcanic rock that is cast into specific shapes, such as tiles, and then used as a lining material. It is known for its excellent resistance to abrasion, high temperature, and chemical erosion.

The cast basalt tiles are typically installed using an epoxy adhesive or mechanical anchoring system to ensure a secure fit. The tiles are designed to interlock with each other, creating a seamless lining that prevents material from getting trapped and causing blockages.

The use of cast basalt tiles in the hopper lining provides several benefits. Firstly, it protects the hopper from damage caused by the impact and abrasion of the material being conveyed. This helps to extend the lifespan of the hopper and reduce maintenance and repair costs.

Secondly, the high temperature resistance of cast basalt makes it ideal for hoppers that handle hot materials. It can withstand temperatures up to 1,200°C (2,192°F) without losing its mechanical properties, ensuring that the hopper remains intact and functional even under extreme operating conditions.

Lastly, the chemical resistance of cast basalt tiles makes them suitable for hoppers that handle corrosive materials. They can resist the attack of acids, alkalis, and other aggressive chemicals, ensuring that the hopper lining remains intact and does not deteriorate over time.

Overall, the use of cast basalt tiles as a lining material in hoppers provides durable protection against abrasion, impact, high temperatures, and chemical erosion.
