Introduction. This article concerns itself with vertical grinding mills used for coal pulverization only (coal pulverizers), although vertical grinding mills can and are used for other purposes.. The 3D model in the saVRee database represents a vertical grinding bowl grinding mill types include the ball tube mill, hammer mill, ball and race mill, and, roll and ring mill.
Although the control of circulating load would help increase the energy efficiency, no quantitative study has been conducted due to the high temperature and pressure in the closed VSP. In this study, response of energysize reduction to the control of circulating load was studied by the experimental simulation method. Coal mixtures with fine/coarse ratio of 11:1, 8:1 and 6:1 were ground by a ...
But when increasing the load of the coal particle phase, the pure air flow simulation without considering coal particle phase will underestimate the pressure loss. It is concluded that the air property with averaged temperature is most suitable for CFD simulation. The present study shows that the CFD simulation is a viable tool in vertical spindle pulverizer design. 【Keywords】 CFD ...
