Last grain of powder is dumped into the mill hopper as another hatch is completely filled. Next batch is in the foreground but will not be started until the present one is completely mixed. Mixing time varies with the characteristic of the batch, both as to the number of ingredients and the speed with which they mix thoroughly into the rubber. General Tires, Akron, Ohio. Sourced from the Library of Congress.
