Farmers in the old days used to hitch up horses or mules to a long pole attached to the center roller in the mill. As the animals walked in circles, the rollers turned crushing cane fed into the mill a few pieces at a time. Ky cane mill ready to press sorghum. We reassembled the mill and lagged it to a few sections of old railroad ties.
A complete mixing can usually be attained in 3 to 6 minutes unless longer time is necessary to eliminate lumps caused by added liquids. Mixer shaft rotation is regulated to provide some centrifugal action, but this must not be excessive.
He also explains how rolling mills can save on time and labor because a rolling mill can produce 10 to 20 or more bars at the same time. A patent was granted to Thomas Blockley of England in 1759 for the polishing and rolling of metals. Another patent was granted in 1766 to Richard Ford of England for the first tandem mill.
4.2.3.1.1 Roll Mills. The roll mill is the simplest batch mixing equipment. The principal design consists of two horizontal rolls, usually of equal size, arranged side by side and rotating toward each other at different speeds. The ratio of the peripheral speeds of the rolls, known as friction ratio, ranges from 1 to 2 but is usually around 1.2.
These roller mills are able to process a large quantity of grain, so rather than bringing grain to local stone mills, significant quantities of grain were transported to centralized roller mills. This meant that along with the loss of nutrition when the new system was introduced, there was also a loss of small-scale milling on the community level.

Optimizing the Ball Mill's RPM Make sure the whole roller assembly now looks as it originally did, and rotates freely. There you go: A larger, 3/4-inch diameter drive roller, simple as that. Test-run the mill with a jar on it, and verify that the speed of the jar's rotation has increased to approximately 80-90 RPM.
Steel Roller Mill in Switzerland. In 1834, a Swiss engineer—Jacob Sulzberger—invented the steel roller mill. Instead of crushing the grains as with stone grinding, these new mills could separate germ and bran by applying slight pressure on the grain. This new method produced extremely high-quality white flour for the baking industry. Baking ...
For improved size reduction one of the rolls rotates faster. This results in a differential in speed between the roll pair. Typical differentials range from 1.2:1 to 2.0:1 (fast to slow). Typical roll speeds would be 1,300 feet per minute (~ 395 m/min) for a 9-inch (~23 cm) roll to 3,140 feet per minute (~957 m/min) for a 12-inch (~30.5 cm) roll.

Excess billet gap can be an unaccounted for loss of rolling time. If a mill rolls 800,000 tons per year using billets of 1.25 ton weight, it rolls 640,000 billets per year. That is 639,999 billet gaps. If the average billet gap is 5 seconds that is (5 sec x 639,999)/3600 sec/hour = 888.89 hours of billet gap. ...
