New Ceramic Composite Solution to Optimize and Upgrade Mine Slurry Scraper

In the process of mine sludge and slurry handling, the scraper is an indispensable tool that removes viscous slurry inside the equipment to keep the system running smoothly. However, the working conditions for this role are extremely harsh: the scraper surface must continuously endure severe abrasion from hard particles in the slurry, chemical corrosion, and constant material impact. Its wear primarily manifests as end-face wear, similar to a pencil being constantly used, causing the scraper to become shorter over time. Under such high-intensity and high-frequency conditions, traditional metal scrapers wear out quickly, requiring frequent downtime for maintenance and replacement, which severely impacts production efficiency and cost control.
 

 

Mining companies have attempted to find better solutions. If wear resistance alone is pursued, pure ceramic materials, with their extremely high hardness, become a candidate, but their brittle nature makes them unable to withstand the inevitable strong impacts in such conditions, leading to breakage. This puts scraper selection in a dilemma: metals lack sufficient wear resistance, while pure ceramics lack adequate impact resistance.
 

Addressing this industry pain point, Kingcera recently provided an optimized upgrade solution that broke the deadlock. The core concept is “composites,” no longer relying on a single material to handle all challenges, but instead designing a three-layer composite structure for the scraper. This structure is like equipping it with a specially designed “armor”: the inner and outer layers are made of stainless steel or other metals, primarily for structural support, with the excellent toughness of the metals absorbing and dissipating most of the impact energy; the middle layer is embedded with high-performance alumina ceramics, fully utilizing its high hardness to serve as the main force against abrasive wear. This design achieves a complementary advantage between the toughness of metals and the hardness of ceramics. 
 

 

It is reported that this batch of ceramic composite scraper products has been delivered to customers and put into use. Customer feedback has confirmed the effectiveness of the solution: under the same working hours and conditions, the wear of the new ceramic composite scraper is less than one-fifth of that of the traditional metal scraper. The significant improvement in wear performance directly translates to longer service life, fewer downtimes for replacement, and tangible benefits for mining customers.
 

This innovative case demonstrates that in addressing complex industrial wear problems, reasonable material composites and structural designs often achieve superior overall performance compared to single materials, providing new ideas for solving persistent challenges in traditional industries.
