Rotary Kiln Spare Parts

The rotary kiln serves as a core production equipment in industries such as cement, metallurgy, and alumina. Its continuous and stable operation directly determines production capacity and efficiency, and high‑quality spare parts are key to ensuring its long‑term performance. We specialize in the manufacturing and supply of rotary kiln accessories and components, covering core parts, integrated assemblies, and key wear components, including support rollers, riding rings, protection plates, bull gear rings, pinions, main gears, and more. With advanced craftsmanship and reliable quality, our products are designed to meet the demands of various operating conditions.

Support rollers and riding rings are the core load‑bearing components of the rotary kiln, working together to enable smooth rotation of the kiln shell. Support rollers primarily bear the weight of the entire rotating section and guide the kiln shell orientation. Through precision forging and heat treatment, they ensure excellent wear resistance and fatigue strength, with machining accuracy tightly controlled to prevent axial movement of the kiln shell. Riding rings, also known as tyres, not only transfer the kiln's gravitational load to the support rollers but also reinforce the radial stiffness of the shell. Through strict forming and finishing processes, they ensure proper contact with the support rollers, reduce operational wear, and extend equipment service life.

Protection plates act as a "protective barrier" for the kiln shell, mainly installed in high‑temperature and erosion‑prone areas such as the kiln inlet and outlet. Their core functions are to protect the kiln shell ends and sealing gaps, and to guide material discharge. The plates offer outstanding resistance to high temperatures and abrasion, effectively withstanding material冲刷 and flue gas erosion. Designed primarily in segmented blocks for easy installation and replacement, some plates are equipped with castable grooves to further extend service life, and they can be customized to fit kilns of different diameters.

The bull gear ring, main gear, and pinions together form the transmission center of the rotary kiln, driving the stable, long‑term rotation of the kiln shell. The bull gear ring, as a critical ring‑shaped component, is manufactured through rigorous forging processes to avoid forming defects, followed by heat treatment and precision finishing to ensure tooth profile accuracy and meshing stability. The main gear and pinions are precisely matched to the bull gear ring. Through precision machining, transmission efficiency is maximized while reducing meshing noise and wear. The coordinated operation of these three components enables precise speed control of the kiln shell, ensuring smooth functioning of the transmission system.

In addition to the core components mentioned above, we also supply a full range of rotary kiln parts and integrated assemblies, including thrust rollers, seals, bearing housings, and more, forming a one‑stop product supply system. Thrust rollers are available in standard and hydraulic types, primarily serving to limit or control axial movement of the kiln shell and ensure accurate and reliable positioning. All components are designed and manufactured according to original equipment standards, enabling seamless replacement and integrated installation, significantly reducing equipment maintenance costs and downtime.

Adhering to the philosophy of "Precision Manufacturing, Efficient Compatibility," we have established a strict, full‑process quality control system from production and machining to finished product inspection, ensuring that all products meet required standards. We can provide customized manufacturing services based on the actual parameters of customer equipment. Supported by a comprehensive supply and after‑sales system, we ensure timely delivery of spare parts and offer professional installation guidance, providing solid support for the continuous and efficient operation of rotary kiln equipment.
