effect of water spray on vertical mill

An experimental study of the extinguishing effect of the

The present paper is dedicated to the study of the extinguishing effect of the waterspraying direction on the vertical fire propagation For the research purpose,first of all,the paper has made a theoretical analysis of the lining material vertical fire spreading process under the influence of water spray Then it has conducted a series of fullscale fire tests on lining materialVertical raw mill pradeep kumar •Apply stable water spray to the control bed, normally fed to the feedside of each roller, check flow consistency on each spray•Know the critical level of gasflow and pressure drop for your mill•Maintain stable millVertical raw mill pradeep kumar SlideShare
