Mill capacity and the stirring speeds were the investigated parameters for the open circuit tests, whereas closed circuit tests were carried out at a constant stirring speed but variable discharge rate Five speed levels used in the open circuit grinding tests are 200, 400, 600, 800 and 1000 rpm The capacities were determined to obtain product Blaine surface areas in the limits between 2000 and 5000 cm 2 /g Closed circuit

In cement production, tube mills having multichambers are traditionally used either in open or closed circuit operations

But closed circuit system is adverse to open circuit system The advantage of closed circuit system is eliminating over grinding phenomenon and reducing temperature of grinding chamber Then the grinding efficiency and capacity is improved In general, the capacity can be improved by 10%20% compared with cement mill when these specifications are similar

re CLOSE CIRCUIT AND OPEN CIRCUIT If you have a cement mill with seprator system and the reject of that seprator is back to your mill its mean it is close circuit

open circuit vs closed circuit cement mill Open circuit cement mill Closed Circuit Cement Grinding cz presentation on close circuit clinker grinding cement ball mill with separator for closed circuit cement grinding mill separator 20 Jan 2011, rejects are returned to the mill Figure 1 presents the design of the clinker grinding system

Some advantages of operating in the open circuit mode vs closed circuit are the minimum equipment requirements, high pulp density discharge and the simplicity of operation Closed Circuit Grinding Closed circuit grinding consists of one or more mills discharging ground product to classifiers which in turn return the coarse product from the size separation back to the mill

In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product In a closed circuit system, coarse particles are separated from the finer product and returned for further grinding Gypsum is interground with the clinker in order to control the setting properties of the cement

For the same median diameter of the product, the rate of powder production in the closedcircuit is about 5% higher than that of the opencircuitThe median diameter of classified coarse particles

Open Circuit Grinding Ball Mill Ball mill open circuit type what means apr the characteristic differences between open and closed circuit grinding systems were examined via the use of a continuous vibration ball mill and a blade type classifier for the same median diameter of the product the rate of powder production in the closed circuit is about higher than that of the open circuit

The cement mill Grinding systems are either 'open circuit' or 'closed circuit' In an open circuit system, the feed rate of incoming clinker is adjusted to achieve the desired fineness of the product In a closed circuit system, coarse particles are separated from the finer product and
