What are the differences between ball mill and rod mill
The rod of diameter from 50 to 100 mm is often used as the grinding medium and the filling rate of rod mill is 35% to 45% while filling rate of ball mill is 40% to 50%. Rod is mainly made of several materials:
density iron magnetic separator
1 sorting efficiency and sorting accuracy is higher than other coal preparation methods. Lump coal separation efficiency up to 99.5%; for the end of coal up to 99%. The accuracy of the sorting lump that may bias E value of up to 0.2 to 0.03; for coal cleaning precision E value up to 0.05 or so.

Grinding Circuit - an overview ScienceDirect Topics
If the critical size material typically 25–50 mm is accumulated the mill energy efficiency will deteriorate and the mill feed rate decreases. As a solution additional large holes or pebble ports e.g. 40–100 mm are cut into the mill grate allowing coarse material to exit the mill. The crusher in closed circuit is then used to

Remember for best results reduce the size of your material to the approximate size of the gold you expect to recover and you will increase your gold recovery rates greatly. For gold panning: try panning material bigger than 20 mesh separately from material smaller than 20 mesh. 20 mesh window screen sized material is the typical point where

Activated carbon in contact with a pulp containing gold and/or silver can typically recover more than 99.5% of the metals in the solution in 8 to 24 hours depending on the reactivity of the carbon the amount of carbon used and the mixer& 39;s efficiency.
SAG Mill - Mining engineering - Eng-Tips
Also depends on the medium in the mill. There are many other solutions however if the efficiency of a SAG mill is not what you are after all of the other options cost more in terms of maintenance and materials eg. pure ball mills hammer mills and rod mills . AG and SAG mills are cheap to operate and some inefficiency is okay due to cost/benefit.
Laboratory Rod Mill - JXSC Machine
Generally speaking lab rod mill is commonly used as a grinder for the mineral feasibility study and for heavy concentrate reduction. Rod Mills is suitable for laboratory wet grinding of fine ore or other material flow. Rod ball mill has the advantages of high efficiency large grinding capacity and uniform particle size.
