As the core equipment of the grinding system for configuring chemical fiber TiO? suspending agent EG, the innovative all-stainless steel alloy grinding machine inner cylinder stands out with its excellent performance. The equipment is produced with special alloy materials and processes, achieving more efficient grinding effects, and its wear resistance far exceeds that of traditional models. Practical verification shows that the service life of this inner cylinder is 2 to 3 times longer than that of ordinary 304 hard chromium-plated inner cylinders, effectively reducing equipment replacement frequency and maintenance costs. The slurry produced by this cylinder features stable quality, with all indicators meeting high industry standards, fully satisfying the production requirements of chemical fibers. With its excellent cost-performance ratio, the equipment not only significantly reduces the production cost of chemical fibers but also enhances production efficiency and market competitiveness for enterprises, especially favored and recognized by many domestic small and medium-sized private enterprises.
