The drag torque of pins at two circles was studied based on validation of the computational model. The key structural parameters and operating parameters of the pin pulverizer were considered in the orthogonal test. The orthogonal test data were non-dimensionalized, and the dimensionless parameters' polynomials were used to fit the data, by which the mathematical model of drag torque of the pin pulverizer was established. The computational results show that errors between the predicted value and CFD calculations of the drag torque of pins at two circles under two different conditions were 9.832%, 28.914% and 10.321%, 5.442%, showing this model could satisfy engineering precision., correspAuthors=null, authorNote=null, correspAuthorsNote=null, copyrightStatement=null, copyrightOwner=null, extLink=null, articleAbsUrl=null, sourceXml=null, magXml=null, pdfUrl=null, pdf=fh10UDdhi/a/V27RsDb0zw==, pdfFileSize=955158, pdfExtLink=null, richHtmlUrl=null, mobilePdfUrl=null, reviewReport=null, pdfFirstPage=null, abstractGraph=null, abstractGraphContent=null, abstractVideo=null, citation=null, cebUrl=null, magXmlContent=null, mapNumber=null, authorCompany=1.
