Coal testing equipment, coal quality testing instrument, coal quality analysis instrument, coal quality instrument, Hebi gangue rate and limit rate. Coal samples can be taken in a moving coal stream or a static batch of coal other than coal piles. It can be taken alone or in accordance with GB/ T9494. or GB475 regulations are adopted. ⑴ It is taken in a mobile coal stream alone, and the sub-samples are distributed at a fixed time interval or a fixed mass interval. For train and automobile sampling, the coal surface is divided into small pieces of approximately -2m in length and width, and then the position of the stator sample points is determined by the systematic sampling method or the random sampling method. ⑵ Take it together with other coal samples. According to GB/T9494. or GB475, when adopting other measurement items and gangue (lower limit) ratio to determine the common coal sample, sampling precision, total sample and number of sub-samples, sub-sample distribution, test The quality of the sample is determined according to the highest required value, and the minimum mass of the total sample should be the sum of the two minimum total sample masses. When manually sampling coal on the top of the transportation vehicle, coal lump (including gangue and pyrite) with a particle size greater than 50mm encountered at the sampling point should be collected.Ya’an city
