HI ALL,
IF SOMEBODY CAN HELP-ME WITH PLANS OR PICS TO ME BUILD A CONTINUOUS FEED ROD OR BALL MILL CAPABLE TO PROCESS ABOUT 2 T/H WILL BE GREAT FOR ME;
THANKS

You’ll need to provided a lot more details of your project before I can offer any useful information. Basically, a continuous feed rod/ball mill is designed with the introduction of feedstock in one end, and the desired grind size discharged out the opposite end. After that, it gets a little more complicated.

There are many factors that will determine a satisfactory result of grinding, including your choice between a rod and ball mill. For example, a ball mill can normally produce a finer grind size than a rod mill. The final grind size is determined by the liberation point of the values you are trying to recover. There are other consideration for grinding, like; hardness or friability of the material, a wet or dry grind, grinding reduction ratio and designing either an open or closed circuit.

I can tell you from experience that a commercial Marcy 5x5 ball mill will reduce 3/8” (9.5mm) feedstock of a chert/quartz material to -100 mesh (150mm) at about the rate of +/-) 1 ton/hour.

I’ve never found it to be very cost effective to build certain types of large equipment, and a rod/ball mill falls into that category. It’s almost a science to construct a piece of equipment of that size when considering such things as, live/dead loads, parts wear and abrasion factors, rod/ball/liner specs, power loads, drive systems and installation requirements. Just to name a few of the problems.

I’ve always found it a lot easier, cheaper and faster to locate used equipment and then modify it to suit my needs. But, that’s your call. With a little more info on your project, I might be able to provide you with some better answers, as I have volumes of information on the subject.

Here are a few web sites on ball/rod/SAG/pebble mills you can check out;
