高精度全自动物料粒度检验装置的研究

Research on High-precision and Automatic Testing Device for Particle Size

结合首钢京唐公司1#、2#两座高炉返焦、返矿物料粒度检验的生产实际,研制了高精度全自动物料粒度检验装置,它由共用一套PLC控制系统的4台相互独立的检验筛组成。阐述了其机械组成、工作原理,重点介绍了检验装置的电气控制部分构成及控制过程、检验原理。出厂实验结果表明:筛分效率大于90%,检验误差小于0.3%,检验精度高,达到了首钢的技术要求。

Combined with the actual particle size testing production of 1# and 2# two blast furnace which the tested coke and sinter need returned in shougang Jingtang company, the high-precision automatic particle size testing device is developed. The test device consists of four independent test sieve which is controlled by a public PLC. the mechanical composition and working principle is described, focusing on the composition and process of electrical controlling part of the test device and the detection principle.. Factory experimental results show that： the screening efficiency is greater than 90%, the detection error is less than 0.3%. The High precision reaches technical requirements of shougang.
