Abstract: | 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. |
