本图使用氧化锆0.6mm研磨珠，每秒11米速度，连续运行38 500小时打开机器情况，无磨损、无锈蚀、无变形，产品质量符合指标要求。

            本公司生产的超耐磨不锈合金钢研磨内筒：采用优质不锈合金钢，经先进工艺精制而成，适用于金属、非金属矿、高温重油及化工钛白粉等物料的研磨作业。产品具备使用寿命长、超强耐磨、耐腐蚀性佳等特点，且不会对物料造成污染，使用成本优势显著。

            可生产及更换500升、1000升至5000升容积的国内外砂磨机研磨内筒，支持内外研磨筒整体交付，也可单独更换研磨内筒（单独更换需在供方生产场地进行）。

            目前，我公司的不锈合金钢超耐磨研磨内筒已成功应用于钛白粉（Tio₂）研磨场景，搭配0.6-0.8mm氧化锆95研磨介质，在11m/s线速度下运行，设计使用寿命可达10年以上。现有案例中，同款产品经5年实际生产运行后无明显磨损，广受用户认可，欢迎预约前往用户使用现场实地考察。

This diagram shows the condition of the machine after continuous operation for 38,500 hours with 0.6mm zirconia grinding beads at a speed of 11 meters per second. The machine is free from wear, corrosion and deformation, and the product quality meets the specified requirements.

The ultra-wear-resistant stainless alloy steel grinding inner cylinders produced by our company are made of high-quality stainless alloy steel through advanced refining processes. They are suitable for grinding operations of materials such as metallic ores, non-metallic ores, high-temperature heavy oil and chemical titanium dioxide. The products feature a long service life, super wear resistance and excellent corrosion resistance, without causing any contamination to the materials, and have significant advantages in terms of use cost.

We can produce and replace grinding inner cylinders of sand mills (both domestic and overseas models) with capacities ranging from 500L to 5000L. We support the overall delivery of inner and outer grinding cylinders, and also provide separate replacement of the grinding inner cylinder (the separate replacement must be carried out at the supplier's production site).

At present, our stainless alloy steel ultra-wear-resistant grinding inner cylinders have been successfully applied in titanium dioxide (TiO₂) grinding scenarios. Matched with 0.6-0.8mm 95 zirconia grinding media and operated at a linear velocity of 11m/s, they have a designed service life of over 10 years. In existing cases, the same type of products showed no obvious wear after 5 years of actual production operation, and have been widely recognized by users.
