When pump valve equipment is operating under conditions of transporting corrosive media, the metal plunger is constantly subjected to medium erosion, resulting in rapid surface wear, formation of corrosion pits, and failure of the seal, causing medium leakage. This leads to frequent equipment shutdowns for maintenance and high costs for spare parts replacement, severely affecting the continuous operation of the production line. The customer originally used stainless steel plunger. Under the condition of acid and alkali mixed media, its continuous operation life was only 820 hours. After wear, the sealing leakage failure rate was relatively high, and the equipment needed to be shut down for maintenance and replacement of spare parts every month...
A lithium battery powder equipment supplier encountered a bottleneck during the commissioning stage of the wet grinding production line for lithium iron phosphate. The original sanding machine chamber was lined with polyurethane, and after continuous grinding for 72 hours, the inner lining showed significant wear and detachment. The debris mixed into the slurry, and the magnetic foreign matter index exceeded the standard. The pass rate of cell inspections dropped to 9.3%. At the same time, the polyurethane material has an insufficient temperature resistance limit. The slurry was heated to above 65℃ during the long-term grinding process, and the aging speed of the inner lining accelerated...

In the production process of lithium battery cathode materials, ultra-fine grinding of lithium iron phosphate requires strict standards for the wear resistance, cleanliness and dimensional accuracy of equipment components. Many lithium battery powder production enterprises in Dongguan are generally facing on-site problems such as rapid wear of the ceramic inner liner of the sanding machine, insufficient compatibility of components, the generation of trace impurities during long-term operation, and unstable purity of batches of powder.
The ultra-fine grinding of lithium battery slurry imposes stringent requirements on the wear resistance and corrosion resistance of internal components in sand mills. Many equipment manufacturers tend to focus solely on unit prices when replacing zirconia ceramic liners, ceramic rotors, and ceramic nozzles, often overlooking material purity and sintering processes. This results in rapid wear, powder shedding, and direct contamination of battery slurry upon initial operation.
Zirconia ceramic is a core wear-resistant component material in the field of powder crushing and fine grinding industries. Due to its excellent toughness, resistance to bumps and bending strength, etc., it is widely used in various powder processing and precision grinding equipment. Looking at the current industry situation, most ceramic processing manufacturers only have the ability for subsequent machining processing, and the core ceramic raw materials are completely dependent on external purchase, unable to control the production process from the source...
