In the lithium mica extraction production line, the roasting system serves as the core hub connecting raw materials to the leaching process. However, the pipelines and elbows that convey high-temperature materials are trapped in a vicious cycle of "wear-through - shutdown - replacement." Data shows that ordinary steel elbows without wear protection often last less than one month under the scouring of 800°C roasted material, with a single shutdown loss potentially reaching hundreds of thousands of yuan. The precise application of wear-resistant ceramic tiles is emerging as the key solution to this industry pain point.
The wear damage in the roasting system originates from the triple challenge of "high temperature + hard particles + impact." After high-temperature roasting, lithium mica forms a porous but sharp-edged clinker, containing minerals such as quartz and feldspar with a Mohs hardness of 7–8, acting like countless tiny steel grits. These materials flow through the pipelines at speeds of 3–5 m/s, and when passing through elbows, the abrupt change in flow direction generates severe impact, causing the wear layer of ordinary steel to be quickly cut and stripped away. Meanwhile, the high-temperature environment accelerates metal oxidation, further reducing the pipeline's wear resistance and creating a dual "wear-corrosion" damage mechanism.
To address such extreme operating conditions, wear-resistant ceramic tiles build a reliable defense line through "material matching + structural optimization." For conventional roasted material conveying pipelines, we adopt 95% high-alumina ceramic tiles with a Mohs hardness of 9 and compressive strength exceeding 300MPa, capable of easily withstanding routine material scouring. At the most wear-intensive locations such as elbows and tees, we upgrade to ZTA (zirconia-toughened alumina) ceramics, which introduce a zirconia phase to enhance toughness, capable of withstanding high-frequency impacts from roasted material, with a service life extending over 50% longer than ordinary ceramics.
Professional construction techniques are equally crucial to ensuring wear protection effectiveness. We use high-temperature-resistant inorganic adhesives to closely bond the ceramic tiles to the inner pipe wall, with arc transition designs at the joints to prevent material blockage and localized wear. To address high-temperature expansion issues, expansion gaps are reserved at the pipe flange connections, ensuring that the ceramic layer does not detach during temperature variations.
In today's lithium industry pursuit of efficient and continuous production, the stable operation of the roasting system directly impacts the efficiency of lithium resource extraction. Wear-resistant ceramic tiles, with their outstanding wear resistance and high-temperature resistance, build an "invulnerable armor" for pipelines and elbows, not only significantly extending equipment life but also reducing shutdown losses and helping enterprises achieve cost reduction and efficiency improvement.
