Decanter Centrifuge Wear Tiles
The scroll conveyor (screw) inside an industrial decanter centrifuge operates under continuous differential speeds, pushing tons of highly abrasive solids against the inner wall of the bowl. This process exposes the flight edges to extreme abrasive wear and particulate erosion. Without adequate reinforcement, bare steel flights quickly erode, destroying the scroll geometry, dropping cake dryness, and leading to catastrophic structural failure.
The decanter centrifuge tile is made of wear-resistant materials, such as tungsten carbide, ceramic, or hard metal alloys. The tile is attached to the bowl by welding, brazing, or mechanical fastening. The tile has a specific shape and size that matches the geometry and design of the bowl.
The decanter centrifuge tile is an essential part of the decanter centrifuge that ensures its performance, durability, and reliability. The tile requires regular maintenance and replacement to prevent wear and tear and to optimize the separation results.
Based on decades of experience in the design, manufacture, commissioning, and maintenance of decanter centrifuges, we have joined hands with relevant material research institutions and enterprises to provide original equipment manufacturers (OEMs) and rebuilders of decanter centrifuges with good wear resistance, high performance long life, reliability, affordable wear resistant components, including decanter centrifuge tile, discharge port liner, and other wear parts.
SEPARATECH manufactures premier aftermarket Decanter Centrifuge Wear Tiles engineered to act as an unyielding shield for your conveyor assemblies. Fabricated from ultra-dense, sintered tungsten carbide, our replacement wear tiles restore original flight flight profiles, dramatically slowing down erosion rates and securing maximum uptime for high-solids dewatering plants worldwide.
Metallurgical Superiority: Sintered Tungsten Carbide (WC)
The exceptional service life of SEPARATECH Decanter Centrifuge Wear Tiles comes down to our rigorous material standards and proprietary powder metallurgy:
- 100% Virgin Materials: We strictly utilize virgin, premium-grade tungsten carbide powder mixed with optimized Cobalt ($Co$) or Nickel ($Ni$) binders, completely avoiding recycled scraps that introduce microscopic brittle fractures.
- Extreme Micro-Hardness: Our tiles achieve an incredible hardness rating of HRA 89 to 92, enabling them to easily withstand harsh contact with quartz sand, crystalline salts, mineral tailings, and calcified grit.
- Impact Toughness: By finely tuning the grain size of the carbide matrix, our tiles balance extreme surface hardness with internal shock absorption, preventing chipping when unexpected large debris enters the feed chamber.
High-Strength Brazing & Step-Lock Bonding Security
Under massive centrifugal forces exceeding 3,000 G, the most common failure point for third-party Decanter Centrifuge Wear Tiles is detachment—commonly known as “flying tiles.” SEPARATECH eliminates this risk through multi-layered engineering:
- Advanced Silver Induction Brazing: Every tile is bonded using computer-controlled, high-frequency silver brazing alloys. This ensures a flawless, void-free metallic joint capable of enduring high shear stresses and structural expansion.
- Backing Plate Options: Tiles can be supplied pre-brazed onto weldable duplex stainless steel backing plates or stepped segments, allowing your local maintenance crew to perform quick, hassle-free plug-welding directly onto the flights.
- Backup Hardfacing Alignment: We provide specialized perimeter carbide hardfacing layout guidance to prevent “under-cutting”—the washing away of the base steel surrounding the tile borders.

Gram-Standardized Weight Matching for Balance Integrity
A decanter scroll conveyor is a heavy, high-speed rotating mass. Replacing worn tiles unevenly can distort the rotor’s weight distribution, leading to severe vibration during startup.
Our Precision Guarantee: All SEPARATECH Decanter Centrifuge Wear Tiles are sorted and grouped using computerized gram-level weight indexing. When you order a replacement set or segment block, every tile features virtually identical mass profiles. This allows your technicians to execute local repairs while maintaining the factory-level dynamic balancing of the total scroll assembly, preserving your main bearings and planetary gearboxes.
