高精度全自动物料粒度检验装置的研究

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。

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

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.
