Coal-fired power plants continue to play a crucial role in the vast power generation system. As the power plant's "food supply," the stable operation of its core components—the crushing and grinding equipment—is directly related to the efficiency, energy consumption, and safety of the entire generator set. These devices operate 24/7 under extremely harsh operating conditions (high wear, high impact, and high dust levels). The performance and quality of these core spare parts are the cornerstone of this maintenance.
As experts in the power industry spare parts field with many years of experience, Zhili New Materials deeply understands the responsibility that each spare part carries. We not only provide products, but also reliable solutions to ensure stable power plant operations.
1. Crushing Equipment Spare Parts: The Key to Efficient Pretreatment
Raw coal or limestone must be pre-processed to the appropriate particle size by crushing equipment before entering the coal mill to reduce the burden on the main grinding equipment.
Common equipment includes: hammer crushers, impact crushers, and hammer crushers.
Core Spare Parts:
Hammers/Strike Plates: Core working components that withstand high-speed impact and wear. We utilize advanced materials such as high-chromium composites, ultra-high manganese steel, titanium carbide alloy rods, hardfacing, and ceramic composites. While maintaining impact toughness, we significantly extend wear life and improve overall performance by over 30%.
Crushing Plates/Liners: We provide liners perfectly matched to the equipment, with materials customizable based on material characteristics to ensure a stable crushing chamber shape and uniform discharge particle size.
Screen Plates/Grates: Key to controlling the final discharge particle size. We optimize the screen plate structural design to effectively prevent clogging.
II. Grinding Equipment Spare Parts: The Heart of the Pulverizing System
The coal mill is the absolute heart of the pulverizing system. For the core of the core—the grinding roller sleeves and grinding disc liners—we abandon traditional single-source manufacturing methods and pioneer the application of three cutting-edge technologies to provide you with solutions that exceed your expectations.
Next-Generation Grinding Roller Sleeve Technology Flagship: Three Cutting-Edge Technologies
High-Performance Hardfacing Regeneration Technology:
Not just repair, but performance enhancement. We utilize an automated robotic overlay welding system and special wear-resistant wire to precisely weld the roller sleeve substrate. The repaired roller sleeve boasts a wear-resistant layer hardness exceeding HRC60, excellent toughness, and strong spalling resistance. Its service life can reach over 90% of that of a new casting, yet the cost is only 50%-60% of the original cost, making it the preferred choice for cost reduction and efficiency improvement.
Alloy Stud Composite Technology:
The ultimate solution for grinding highly abrasive coals with high quartz content. We drill holes into the roller sleeve substrate and press-fit ultra-hard alloy studs, creating a robust "wear-resistant matrix." The exposed studs absorb the majority of the grinding wear, effectively protecting the substrate. This technology is particularly suitable for use in severe wear conditions, extending the lifespan by double or even several times that of traditional roller sleeves, significantly reducing replacement frequency and delivering significant overall economic benefits.
Ceramic-Metal Composite Technology:
An industry-leading innovation. Through advanced processes, high-purity, ultra-hard alumina ceramic blocks are seamlessly bonded to a highly tough metal substrate. Ceramics offer unparalleled wear resistance, while the metal matrix ensures overall impact resistance. They are particularly well-suited for severe erosion and wear, effectively addressing the challenges of varying coal quality with stable and long-lasting performance.
Separator Guide Vanes/Baffles: Our blades can be finished with ceramic overlays or wear-resistant hardfacing. The smooth surface and precise angles effectively reduce drag, improve separation efficiency, and help power plants achieve economical combustion.
Core Reducer Components: The "heart" of the coal mill. We provide high-precision gears, thrust washers, plain bearings, and seals, using materials and processes that match OEM standards.
