Table of ContentsCase 1Case 2General Notnclusions A Knowledge of the amount of time the material spends in a continuous mill in a closedgrindingcircuit is essential for circuit performance analysis and scaleup design. A convenient method for acquiring this information involves the use of tracers in residencetimedistribution (RTD) experiments. In a typical wet process the RTD
in the mill was best described by the perfect mixing cells in series with exchange model which fitted well with the experimental outlet response curves of the mill. Keywords: Clinker, dynamics, Feed, mill, residence, time. INTRODUCTION The main raw material for cement production is clinker. Cement
Heat loss distribution across different elements can be established through heat balance and process audit of pyro section. Fuels used commonly to provide heat for the conversion processes are coal, fuel oil, and natural gas. Alternative fuels like petcoke, rubber tyres, wood chips, etc. have been introduced to economize cement making process.
#0183;#32;It has been demonstrated that the proposed oneparameter model can be successfully used to describe the residence time distribution of rod mills and ball mill with a high degree of accuracy. A significantly broad range of the normalized variance of RTD ( to ), corresponding to values in the range of 2 to 6, was covered in the examples presented.

#0183;#32;The residence time distribution (RTD) of mineral slurry and slurry holdup volume in an industrial ball mill has been successfully studies using tracer tests. Six different conditions of solids concentration and three levels of ball loading were assessed. The effects of the slurry solids concentration and the ball loading on the mean residence time of slurry were clearly depicted in the
#0183;#32;Re: MATERIAL RETENTION TIME IN A BALL MILL amp; VRM. You could do that by measuring the material flowrate Q[tons/h] through the mill as well as the quantity M[tons] of material that accumulates within the mill. The retention time, also called residence time, is the ratio (M/Q) [h] .
residence time of the cement in the mill. The plant can hence achieve a greater throughput in addition to reducing the proportion of offspecification product during product changeovers. The Bettersize BTOnline1 particle size analyzer measures the fineness measurement in production in real time, producing a 57% increase in throughput or a

Radiotracer Residence Time Distribution (RTD) m ethod was used to invest igate the process of clinker grinding in Ghana Cement Plant (GHACEM) at Tema with the objective of determining holdup and grinding efficiencies of two ball mills operating in close circuit regime. The experiment was conducted using 40Ci Au198 radiotracer in liqui d stat e and highly sensit ive NaI detectors for
The vertical mill cement grinding power consumption is low, grinding cement does not need auxiliary cooling, and the residence time of the material in the mill is very short, can quickly convert from one species to another species, does not need to be a lot of grinding material out, but also in the production process of rapidly changing product particles.
Radiotracer Residence Time Distribution (RTD ) method was used to investigate the process of clinker grinding in Ghana Cement Plant (GHACEM) at Tema with the objective of determining holdup and grinding efficiencies of two ball mills operating in close circuit regime.
An added advantage is that the residence time of the cement in the mill is reduced such that throughput can be increased by 5%. For a plant operating at full capacity, an extra 5% can result in a payback time of less than 3 months and a plant not operating at full capacity, the reduced energy costs can result in a payback time lt; 1 year.

#0183;#32;The tanksinseries law (Levenspiel, 1972) permits the definition of the mean residence time and the variance as: l lp+2ls+t''1 (9) 2 22 a = 2l s+or1 (10) It is very convenient to express the RTD in dimension1ess time units in order to isolate mixing properties from overall mass trans#173; Residence Time Distribution and Mass Transport Characteristics port phenomenon and to compare various
