For fine regrinding in open circuit, the ratio ranges from :1 to :1. Some ball mills are separated in to compartments by grates. The grates hold back particles above a certain size for additional grinding. The compartments could contain different ball sizes. Large to small from the feed end. Some mills have a conical section.
The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill. The spiral classifier is popular in pilot plant grinding due to the ease in which the oversize is returned to the mill . continuous small ball mill
Ball mill is a kind of grinding mill used in the mineral processing, which is to further grinding the material fitness to the appropriate particle size that meets the industrial requirement after the crushing process. At present, the ball mill machine is widely used in mine, cement, silicate products, building materials and other fields. 1. Structure of ball mill

Ball Mills. The term ball mill is generally used to refer to a cylindrical mill whose length is less than, equal to, but not much greater than its diameter. It was initially developed for relatively coarse grinding, but by using it in closed circuit with a classifier its use has been extended for fine grinding.
Keywords: Stirred mill, ball mill, micronized grinding, breakage behaviours, Oct 4, 2013 SUBJECT: SAG MILL + BALL MILL CIRCUIT SIZING. Summary: devices is (largely) reflective of the efficiency of the grinding device. Once the ing a better efficiency of the ball mill for a higher density, a better grind for worn liners and high J.
Open Circuit Close Circuit In the above circuits, material is fed from hoppers to ball mill for reducing the size to microns. In closed circuit, micro particles are fed to classifier for segregation of desired material (based on its size) and rejected one is once again passed through ball 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.
Sepors 16 x 32 continuous ball or rod mill is ideal for pilot plant studies of ore grinding and processing or just regular small scale grinding requirements you may have. The mill can be used in a closed circuit, with a spiral classifier, screen or cyclones or as a single pass grinding mill.
AG/SAG mills can accomplish the same size reduction work as two or three stages of crushing and screening, a rod mill, and some or all of the work of a ball mill. Because of the range of mill sizes available, AG/SAG milling can often be accomplished with fewer lines than in a conventional rod mill/ball mill circuit.
The SAG mill trommel undersize is combined with the ball mills discharge and pumped to two parallel packs (clusters) of twelve 660 mm diameter cyclones. The cyclone underflow from each line reports to a ball mill, while the cyclone overflow is directed to the flotation circuit. The designed ball milling circuit product is 80% passing 150 #181;m.

The (Open) Batch Mill makes possible simulation of grinding in a ball millclassifier circuit by grinding a fixed time, then hand classifying with a sieve and a bucket and returning the sand to the mill for further grinding. Pulp volume can be kept at a minimum by control of wash water since the ball
