RingRoll and BallRace Mills A ball or roller between two races or rings provides the grinding surfaces on which pulverization occurs. One or both of the races may rotate against a ball or roll (in a RingRoll Mill, the rolls may rotate while the ring is stationary).
A machine used to spin cotton and other fibers in the British mills, used extensively from the late 18th to the early 20th century. It was invented between 1775 and 1779 by Samuel Crompton. The machines were worked in pairs by a minder, with the help of two boys: the little piecer and the big or side piecer.
