Vrm and ball mill circulating load page 1 of 1.Sep 07, 2011 re vrm and ball mill circulating load.Mainly in usa, the term circulating load is more often used than the circulation factor.Circulating load is percentage of coarse return in relation to fines it can be calculated by coarse return tph x 100 mill output tph.Normal range of cirulating load in a conventional close circuit ball.
Close circuit grinding of cement mill.Ball mill we bring forth a highly advanced ball mill specifically engineered for both wet as well as dry cement grinding applications classified depending on the circuit design bearing grinding type and drive the selection is made on the basis of the product fineness quality and nature of raw material site conditions and specific requirements.
Apr 15, 2004 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 5 higher than that of the open-circuit.

Friends i have some questions about cement mill.What is the differnce between static and dynamic separators plz explain open and close circuit ball mill.How cement mill roller press works how we can find efficiency of osepa separator how we can find mill circulating load friends please dont mind my questions ia m very new in.
Depending on the selected system, the ball mill is in open or closed circuit in most applications the ball mill is in closed circuit.Finish grinding system.The ball mill is omitted, and all grinding work is done in a more efficient comminution machine.The possible systems are roller press with desagglomerator and rotor type separator.
Closed or open circuit grinding systems.In recent days, the ball mill grinding systems are used with the roller press and it is developing very fastly.The primary grinding is done by the roller press and finish grinding takes place in ball mill.Because of this, we can increase the ball mill capacity as well as the cement production.
Ball mill design.A survey of australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters morrell, 1996.Autogenous mills range up to 12 meters in diameter.The length-to-diameter ratios in the previous table are for normal applications.For primary grinding, the ratio could vary between 11and.
Our ball mill has been designed with two grinding system open circuit grinding system and close circuit grinding system.Our ball mill has adopted special intergrate diaphragm and discharge grate to adjust material levels of every chamber so as to increase air ventilation and improve conditions inside mill meanwhite it has also used new type.
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 5 higher than that of the open-circuit.
Definition of closed-circuit grinding a size-reduction process in which the ground material is removed either by screening or by a classifier, the oversize being returned to the grinding unit.Typical examples are a dry pan with screens, dry milling in an air-swept ball mill, and wet milling in a ball mill.
The practical potential for increasing ball mill circuit capacity using existing fine screening technology was estimated to be in the order of 1525 thus, offering significant potential to reduce energy consumption in mineral processing.
