In this case the grinding circuit comprises an open circuit rod mill followed by a closedcircuit ball mill. The ball mill is most often closed over a classifier like a hydro cyclone (Fig. ) or DSM style screen with a fine cut of mm. The course material is returned to the ball mill feed and the fine screen underflow reports to the ...

There are a lot of factors that go into the cost of a sieve. Things like: what metal it is made of, the opening size of the mesh used in the sieve, and the diameter of the sieve itself. The video below provides a more indepth breakdown of how these factors affect sieve price. As you heard in the video, a sieve can cost anywhere from 75 to 930.
