In the global mining industry, especially under the high-standard, intense conditions of Australian iron ore operations, equipment wear resistance is crucial. It directly impacts productivity and operating costs. Recently, as client demands have grown – requiring larger liner sizes (like the maximum 900*600mm), higher precision, and more complex designs (including curved and angled shapes) – traditional liners have struggled to keep up.
Kingcera has successfully broken through these industry barriers. Using large alumina
ceramic liners and mature rubber vulcanization technology, it has become one of the few global suppliers capable of meeting all these needs at once: large size, high precision, complex structures, and vulcanization with ultra-low gaps.
1. Technical Breakthrough: Full Control from Raw Materials to Finished Product
Material Advantage: Kingcera operates its own alumina powder production line. With advanced equipment like ball mills and spray granulation towers, plus a strict quality control system, it ensures high purity and uniformity of the ceramic base material. This builds a foundation for excellent wear and impact resistance from the very start.
Forming & Sintering: The company is equipped with large isostatic presses, high-tonnage dry presses, and various kilns. This allows stable production of large-sized ceramic components, avoiding common issues like deformation and cracking during sintering, and enables reliable mass delivery.
Precision Machining: Using high-precision CNC equipment and precise measurement systems, Kingcera controls the dimensional tolerance of ceramic liners to within ±0.005 millimeters. This ensures a perfect fit for clients' strict requirements on complex curves and angles.
2. Vulcanization Process: Smaller Gaps, Longer Life
To meet the dual needs of impact resistance and sealing in the iron ore industry, Kingcera leverages its in-house rubber vulcanization expertise:
Its complete vulcanization equipment and process ensure a strong bond between ceramic and rubber, resulting in a gap rate significantly lower than the industry average.
With mature rubber formulas and a vast database of vulcanization parameters, it can tailor solutions for different working conditions, preventing risks of debonding or cracking.
Large-sized liners can be vulcanized in a single step, reducing seams, minimizing material clogging risks, and extending maintenance intervals.
3. Market Validation: Earning International Recognition with Proven Results
Kingcera's large-sized alumina ceramic liners are now used at scale in Australian iron ore mines. Customer feedback indicates a wear life increase of over 30% compared to traditional liners. Furthermore, the extremely small gaps have significantly reduced downtime for cleaning. This success stems from Kingcera's deep integration of materials science, precision ceramic machining, and vulcanization.
With over 30 years of focus on wear-resistant ceramic technology, Kingcera possesses full in-house capabilities—from powder preparation and sintering to precision machining. Its products serve numerous industries including power, mining, and cement. The company continues to invest in R&D, committed to providing global clients with wear solutions that use longer and cost less.
