TO REALLY DESIGN A TROMMEL YOU NEED TO HAVE A PRODUCTION GOAL IN MIND, A 36" DRUM I WOULD CONSIDER  A SMALL PRODUCTION OR BULK TESTING PLANT (20 TO 30 TPH)  SO I WOULD ASSUME IT WILL BE FED BY A MACHINE OF SOME KIND, IT IS HARD TO AVOID A FEED SURGE WHICH CAN OVERLOAD THE BARREL, MY HUMBLE OPINION IS A DIRECT DRIVE TO AVIOD STALLING THE PLANT OR GRAVITY DRIVE SO THE MORE MATERIAL FED THE MORE WEIGHT ON THE DRIVE WHEELS. I USED TO HAVE A LITTLE BALL MILL THAT WAS BELT DRIVE, IT WORKED AWESOME UNTIL IT RAINED OR THE BARREL GOT WET. I BUILT A 32" X 10' TROMMEL 2 YEARS AGO CHAIN DRIVE  AND IT WORKS RAIN OR SHINE. GOOD LUCK
