Hi Kherseth
For what your up to you need both rollers driven for best effect - perhaps a couple of identical gears on one end ? . The other thing I notice is that instead of there being a left and a right hand groove on the cylinders the grooves appear to be the same hand (only going by picture). Left and right hand grooves ensure a shearing action on the grains and having both rollers rotating will drag the grain into the mesh.
I presume you only want to crack the outer layer rather than crush it. You will need to have an adjustment to set the gap correctly for the size of malt you are using. You may get away with coarse gears (large teeth) giving limited adjustment by altering the mesh depth. Alternatively a cross over pulley arrangement may work - if it was me I'd motorise both rollers on principle as I'm a lazy b**ger ;D.
Good luck and don't get discouraged by your initial results. Half the fun is when these things finally work is the satisfaction of knowing you overcame the challenges involved.
Best Regards
