Heavy-duty Liner
Robust steel-backed stone slabs engineered for slag dredger linings, delivering exceptional abrasion, thermal, and corrosion resistance in power plants.
Cast stone slabs designed for slag dredger systems in thermal power plants—offering superior wear, heat, and corrosion resistance to protect against abrasive slag flow.
Cast stone slabs for slag dredgers are heavy-duty lining panels specifically designed for the harsh slurry and high-temperature environment of slag handling systems in thermal power plants. Built with precision-molded natural stone—commonly basalt or cast stone—bonded to steel backing plates, these slabs create a resilient interior surface that resists erosion, high heat, and chemical attack.
High-Hardness Lining: Utilizes dense stone slabs with Mohs hardness of 7–8, typically 20–40 mm thick, to resist impact and sliding wear from hot slag and ash.
Steel Backed for Strength: Stone is bonded to steel plates or frames, ensuring structural stability and easy integration with hydraulic dredger systems.
Thermally Stable Bonding: Mortar or epoxy adhesives withstand temperatures up to 450 °C, maintaining adhesion under thermal cycling and vibration.
Exceptional Wear Resistance: Stone slabs protect against abrasive and high-speed slag streams, dramatically extending equipment lifespan.
Heat & Corrosion Durability: Resistant to thermal stress and chemically inert in alkaline or acidic ash environments.
Smooth, Low-Friction Surface: The sleek stone lining promotes efficient slag flow and reduces material buildup.
Modular & Replaceable: Slabs are sized to fit dredger contours; individual units can be swapped during maintenance with minimal downtime.
Robust Structural Support: Bonded steel backplate combined with stone slab ensures resistance to flow impact and mechanical stress.
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.

Basalt casting was used as a replacement for iron and steel, which were in short supply after WWII. The crushed natural basalt is heated back to molten lava and then poured into molds to make components such as pipes and floor tiles, which are incredibly hard-wearing and abrasion-resistant.
Cast basalt can be formed into a diverse range of shapes and surface patterns, including bespoke designs (min 325m²). During the cooling process, the surface of the material achieves a glass-like patina, with an iridescence and texture that is unique to each piece.
Cast basalt is produced by melting selected natural basalt – broken into sizes of 20–50 mm – in shaft furnaces at temperatures around 1,300°C, followed by casting into the desired molds. Of fundamental importance is the subsequent tempering process, in which the molten basalt forms uniform, spherulitic crystals that contribute to its physical properties such as extreme hardness and abrasion resistance.
Cast basalt is the most frequently used wear protection material. The main areas of application are the wear-resistant linings for:
The walls and outlets of bunkers, silos, and other tanks used for the storage of bulk materials are subject to strong abrasive wear. Strong friction wear occurs when emptying is compounded by impact wear during the filling process.
A wear-resistant lining with hexagonal or rectangular cast basalt tiles has proven to be a successful and economical solution. Special form pieces are manufactured for the flutes and the bunker saddles. Circular bunkers and silos are lined with radial, rectangular, or hexagonal form pieces that precisely match the required circumference.
To improve adhesion, corrugated wire mesh is spot-welded to the vertical steel walls.
The transport of abrasive media, in fact of virtually all granular materials, in enclosed pipelines has the advantage that it is non-polluting, generates neither dust nor smell, and even saves valuable space. Completely lined pipes can be manufactured with the following maximum lengths:
Cast basalt lined piping is extremely wear-resistant and is used wherever highly abrasive materials are conveyed pneumatically or hydraulically, for example:
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.
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.
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.
