trump curve in cement mill separator

grinding mill ball curve pdf - SlideShare- trump curve in cement mill separator ,Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing , consisting of a tube ball mill and a high efficiency separator was introduced through the matrices of , Tromp curve of the.نحوه ارزیابی عملکرد سپراتور آسیاب گلوله ای, انرژی مصرفی ویژه الکتریکی(KWh/t) شده، هزینه محصول نهایی را بالا می برد عملکرد یک سپراتور دینامیک توسط سه پارامتر زیر ارزیابی می گردد: 1- بار در گردش(Circulation Load) 2- راندمان جداسازی (Efficiency) 3- منحنی ترامپ (Tromp Curve)





Separator performance - CemNet

without Tromp curve what is the way to judge the separator performance by seive analysis of rejects,feed & fin what is the normal range of residues , (for cement as well as raw meal) what is the optimum efficiency of a high efficiency separator? raj , If the bypass is 40%, and if the production is 100 t/h, then, naïvely speaking, this means that 40 t/h of good product is returned to the mill
