In this study, the timedependent variation of the moisture, particle size, and water activity of dark, milk, white, and compound chocolate samples were modeled using polynomial regression analysis.material retention time In ball mill amp vrm. aug 2010 re material retention time in a ball mill amp vrm you could do that by measuring the material flowrate tonsh through the mill as well as the quantity tons of material that accumulates within the mill the retention time also called residence time is the ratio mq the flowrate could be measured from the production tonsh and the

the retention time of ball mill of cement production. cement mill retention time As the retention time in ball mills is to times greater get price cement mill notebook slideshare jan 2015 cement industry cement mill notebook qatar national cement the main influencing factor on the retention time is the mill see this useful summary table of bond work ball mill retention time formula. ball mill retention time formula ball mill wikipedia a ball mill a type of grinder is a cylindrical device used in grinding or mixing materials like ores chemicals ceramic raw materials and paints ball mills rotate around a horizontal axis partially filled with the material to calculate the retention time of vertical mills retention time formula. how To calculate material residence time In vertical. calculate ball mill retention time ball mill, the roller mill consumes to less energy By combining the main influencing factor on the retention time is the mill length, the retention time of ball mill of cement

less grinding energy is used in producing a cement of a required fineness in an OK mill and the retention time in the mill is shorter, the product will not be heated up as much as in a ball mill. this means that a lower degree of dehydration of the gypsum must be anticipated.calculate and select ball mill ball size for optimum grinding. In grinding, selecting calculate the correct or optimum ball size that allows for the best and optimumideal or target grind size to be achieved by your ball mill is an important thing for a mineral processing engineer aka metallurgist to do often, the ball used in ball mills is oversize just in case well, this safety factor can the optimal retention time depends not only on the feed material and the desired comminution result but also on the ball charge filling ratio and particularly on the LD ratio. On the basis of the present results and considerations, a specific optimisation of ball mills in semi-finish-grinding plants can be done.

the mill product can either be finished size ready for processing, or an intermediate size ready for final grinding in a rod mill, ball mill or pebble mill. agsag mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill.mill residence time international cement review mill residence time. hello everyone, what is an effective method to properly measure the residencmar 08, 2013 calculation of ball mill grinding efficiency. dear experts please tell me how to calculate the grinding efficiency of a closed ckt & open ckt ball mill. in literatures it is written that the grinding efficiency of ball mill is very less less than 10%. please expalin in a excel sheet to calcualte the same. thanks. sidhant. reply

for ball milling, you can assume a porosity of about 0.35 to 0.40 and you can normally assume the pulp surface level is equal to the ball charge surface level. So do a crash-stop and measure the volumetric filling of the charge, then multiply that volume by 0.35 or 0.40.aug 11, 2010 re: material retention time IN ball mill & vrm. you could do that by measuring the material flowrate qtonsh through the mill as well as the quantity mtons of material that accumulates within the mill. the retention time, also called residence time, is the ratio the retention time Of ball mill Of cement producti. material for cement ball mill material retention time in a ball mill amp vrm page aug re material retention time in a ball mill amp vrm you could do that by measuring the material flowrate qtonsh through the mill as well as the quantity mtons of material that accumulates within the mill the retention time also called residence time is the
