Abstract
Description
technical field
[0001] The invention relates to a modular coal automatic sample preparation and analysis system and method, especially suitable for automatic sample preparation of coal sample raw materials. Background technique
[0002] The coal industry needs to conduct laboratory analysis on coal quality, such as analyzing coal moisture, ash, volatile matter, fixed carbon, calorific value, sulfur content, etc. In order to meet the requirements of analysis, it is also necessary to carry out sample preparation work on coal sample raw materials. In the prior art, the sample preparation and analysis of coal are mainly performed manually by a stand-alone device. For example, in the sample preparation work, the raw material is first crushed with a jaw crusher or a double-roll crusher, and then divided, and then the sample is ground with a grinder to the particle size required for the analysis sample. After the analysis sample is taken to the analysis laboratory, the operator m...
