For primary grinding, the ratio could vary between 11and 1.81. For fine regrinding in open circuit, the ratio ranges from 1.31 to 1.51. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The.
Apr 15 2004 183 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.

Development of Grinding and Classification Technology It was discovered that closing a grinding circuit with a classification device was beneficial to the comminution process. The first classifiers used in closed grinding circuits were mechanical rake and spiral classifiers and both were used effectively in early grinding circuits.
The aspect ratio mill diametermill length of autogenous and semi autogenous mills varies widely and can be as high as three or as low as 0.5. The literature on the subject of what effect aspect ratio has on grinding mill performance or energy efficiency is almost non-existent. However, at the design stage of many 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 for further grinding. In this circuit, grinding efficiency is very dependent upon the size separation effected so care should be exercised in selecting the type and size of classifier used to close the system.

The Kinross Kubaka Project is a gold mine located in the Russian Far East. The grinding circuit, comprised of a 6.1 m diameter x 2.74 m long SAG mill and a 4.1 m diameter x 5.5 m long secondary ball mill in closed circuit with cyclones, was built using SAG Power Index and Bond Ball Mill Work Index testing to determine the grinding energy.
A simple relationship quantifying the effect of classification efficiency and recirculating load on grinding circuit capacity is presented in this paper. The possibility of improving the capacity of ball mill circuits by improving classification efficiency is discussed, considering the current practical limitations of classification equipment.
Open grinding circuits vs closed grinding circuit mining MOBILE CRUSHER Mobile Crusher Introduction. Mobile crusher also named protable crusher is a new crusher equipment, it provides a new field of business opportunities.
In an open circuit system, the feeding rate of clinker is adjusted to achieve the desired granularity of the product at the mill exit. In a closed circuit system, coarse particles are separated from the finer product and returned for a further grinding. In a closed circuit mill, the total throughput is higher and hence the size of material from.
