Custom Cast Basalt Tiles & Cylinders for Extreme Wear Protection

Premium cast basalt lining for ducts, pipes, chutes, and nozzles—molten basalt cast into custom tiles and cylinders. Exceptional abrasion, corrosion, and temperature resistance for mining, power, cement industries. Extend equipment life 5-10x vs. steel; smooth flow, low maintenance, traceable solutions for harsh environments.

What is Cast Basalt Lining?

Cast basalt lining is produced by melting natural basalt rock at ~1300°C and casting it into precise shapes, creating an extremely durable, wear-resistant material. It forms custom tiles for trays/chutes and cylindrical segments for pipes/nozzles of any diameter or configuration.

The result is a chemically inert, non-magnetic volcanic rock lining with a smooth surface that prevents material buildup and ensures optimal flow—even in abrasive slurries, corrosive gases, or high-temperature environments.

Key Properties & Advantages

  • Extreme Abrasion & Erosion Resistance: Outperforms steel, rubber, and ceramics in sliding wear applications.
  • Superior Corrosion Resistance: Inert to most acids, alkalis, and chemicals—no degradation over time.
  • High Temperature Tolerance: Suitable for hot gases and materials; excellent thermal shock resistance and insulation.
  • Smooth Flow Surface: Prevents clogging and material adhesion in pipes and ducts.
  • Extended Service Life: 5-10× longer than steel linings; dramatically reduces downtime and replacement costs.

Process of Cast Basalt Tiles

Cast basalt tiles are produced by remelting natural volcanic rock at extremely high temperatures and recrystallising it under controlled conditions — creating one of the hardest and most abrasion-resistant industrial lining materials available.

1. Raw Material Selection & Crushing

High-quality natural volcanic basalt rock is carefully selected and crushed into fragments typically 20–50 mm in size. Premium cast basalt uses 100% pure basalt with no additives.

2. High-Temperature Melting

The crushed basalt is fed into a shaft furnace (gas or electric) and melted at 1,250–1,500°C (usually ~1,300°C) until it becomes a fully liquid, lava-like melt.

3. Casting into Molds

The molten basalt is poured into preheated metal or sand molds to form tiles (square, hexagonal, rectangular), cylinders, or custom shapes. Thickness is typically 20–50 mm. The back side is often textured for better bonding.

4. Demolding

After initial cooling, the still-hot castings are carefully removed from the molds while maintaining thermal control to prevent cracking.

5. Controlled Annealing – The Key Step

Castings undergo a precisely controlled slow cooling process (16–48 hours) in an annealing furnace. This allows uniform devitrification and formation of fine spherulitic crystals, resulting in Mohs hardness ~8 and abrasion resistance 10–30× greater than steel.

6. Finishing (Optional)

Tiles can be cut, ground, drilled, or polished as required. During cooling, the surface naturally develops a unique glass-like, iridescent patina that is characteristic of cast basalt.

Final Product

The result is an extremely dense, non-porous material with near-zero water absorption, exceptional chemical resistance, and service life many times longer than steel, rubber, or conventional ceramics in abrasive environments.

Inspection Cast Basalt Tiles

Inspection cast basalt tiles offer excellent abrasion, chemical, and impact resistance, ensuring long service life for floors, chutes, and lining surfaces.

Inspection cast basalt tiles are high-performance ceramic tiles made from natural volcanic rock that has been melted and cast into precise shapes. After controlled cooling, the material forms a crystalline structure with exceptional hardness (Mohs 8), high compressive strength, and outstanding chemical stability.

Frequently Asked Questions

Everything you need to know about Basalt Tiles

Basalt is the new miracle fire-protection material. It is made from volcanic rock and can withstand 2500 degrees for an unlimited time while having 3 times the tensile strength of steel.

Compared with traditional concrete, basalt-fiber-reinforced concrete has the advantages of higher tensile strength and less cracking.

Cast Basalt is a naturally occurring basalt-rock wear-resistant material. Offering superb abrasion resistance, this mineral is quarried, melted, cast, and annealed to form a fine-crystallized glass-ceramic of extreme hardness that resists erosion. Cast Basalt is supplied in pipe and tile form and provides an excellent hard-wearing surface for corrosive wear and abrasion protection of equipment.

  • Wear Protection Applications up to approximately 400°C
  • Increases coefficient of friction as it wears, creating favourable flow conditions
  • Available in straight pipe, bends, and shapes
  • Mohs ceramic hardness of 8, diamond has a value of 10.

  • Extended service life of equipment used in abrasive and corrosive applications such as mining
  • Improved service life at cost-effective pricing.

Cast basalt tiles are known for their excellent wear resistance and are commonly used in applications where abrasion and corrosion resistance are critical, such as in pipelines, chutes, hoppers, and other high-wear environments. Having these tiles in stock allows for a quick response to customer demands and efficient fulfillment of orders.

Hard & Compact Smooth & Inner Withstands High-Abrasion & Corrosion In any of the process industries especially Sled and Cement corrosion and abrasion lead to significant downtime of the plant. Further, the useful life or the equipment itself may get impaired because of the high abrasive nature of the materials being used. Thus, ‘wear mechanism’ results in hut down, replacement, etc., which is costly, resulting in loss to tilt: tunic of millions of dollars.

Cast Basalt Tiles Construction Site

Cast basalt tiles construction site

Basalt tiles can be placed and jointed in cement or specially-defined bonding agents, as demanded by the intended application. Basalt tiles can be provided with a central hole that is countersunk for individual bolting, or as ready-made liner plates and pipes.

Cast basalt tiles are 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.
