| Abstract: | According to the problems in the section of sampling on trains,such as large differences in particle size between cleaned lump coal and screened slack coal,non-uniform blending and big error in precision determination in manual sampling,the automatic belt sampling equipment was introduced to substitute for manual sampling.The operation details should be noticed so as to improve precision of blended coal sampling. |
