closed circuit grinding closed-circuit grinding is widely used in cement mills all over the world. cement grinding unit is widely used in the united states, germany, france, japan and other developed countries. for example, 95% of cement in japan comes from closed-circuit grinding.

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 returned for further grinding.

Isamill advantages. 1. energy efficiency. simply energy efficiency is about media size. smaller media has more surface area and higher media / particle collision frequency making it more efficient. the high intensity in the isamill means small media can break coarse particles.

for blaine fineness of over 3000 cm2 /g a closed grinding circuit obtains a lower consumption (kw/t) than the open one. 2.0 diameter amp length of mill the diameter and the length of a tube mill depend on various factors. the most important factors are capacity, hardness of the material, feed size, fineness of the finished product, open or .

01 the specifics of two grinding ways. opening-circuit grinding is that, in the grinding operation, the material is fed into the mill and discharged after a grinding, directly into the next mill or the next process.. the advantages of opening-circuit grinding are simple processing flow and lower investment cost. while the disadvantages are lower production rates and large energy consumption.
