To really choose, I guess it depends on the material and your mill (vial, RPM, media, filling volume). I.e. Si80Ge20 is easily alloyed in the high energy SPEX mill.
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 1:1and 1.8:1. For fine regrinding in open circuit, the ratio ranges from 1.3:1 to 1.5:1. Some ball mills are separated in to compartments by grates.
Grinding Mill Design & Ball Mill Manufacturer. As the length to diameter ratio of the mill should be in the range of 1,2-1,5, the biggest rod mill will convert maximum 1500 kW. Rod mills are used for primary grinding of materials with a top size of 20-30 mm (somewhat higher for soft materials).Онлайн-запрос
The grinding circuit comprises one 8530 mm diameter x 3650 mm semi-autogenous mill driven by a 3954 kW variable speed dc motor, and one 5030 mm diameter x 8340 mm secondary ball mill driven by a 3730 kW synchronous motor.
8.3.2.2 Ball mills. The ball mill is a tumbling mill that uses steel balls as the grinding media. The length of the cylindrical shell is usually 1–1.5 times the shell diameter ( Figure 8.11). The feed can be dry, with less than 3% moisture to minimize ball …

Grinding Mills an overview ScienceDirect Topics. The circuit comprises a SAG mill, 12 m diameter by 6.1 m length (belly inside liners, the effective grinding volume), two pebble crushers, and two ball mills in parallel closed with cyclones. The SAG mill is fitted with a 20 MW gearless drive motor with bi-directional rotational capacity.
18.9.3 Grinding Mill Control in Closed Circuit. The principle objective for controlling grinding mill operation is to produce a product having an acceptable and constant size distribution at optimum cost. To achieve this objective an attempt is made to stabilize the operation by principally controlling the process variables.
Ball mills are commonly used in the manufacture of Portland cement and finer grinding stages of mineral processing one example being the Sepro tyre drive Grinding Mill. Industrial ball mills can be as large as 8.5 m (28 ft) in diameter with a 22 MW motor 4 drawing approximately 0.0011 of the total world s power (see List of countries by get price
ting gear ratios, service factors, and motor power ratings. For gearless drives, motor torque output at the maximum desired operating mill speed and ball charge volume has to be determined. Primary Mills: Torque Output (by Motor) vs Torque Demand (by Mill) For the purposes of this discussion, "drive speed" refers to
