The Movement of the Millstones (Starting and stopping a pair of millstone) The miller would open a sack of grain and pour it into the millstone hopper, or the grain would already be stored above the millstones in a bin on the floor above.This should be of major importance to the United States in its efforts to reduce dependence on imported oil and to rely on its enormous low-cost coal resources. In accordance with this objective, in the first stage of this project, considerable work was conducted to standardize experimental procedures for sample preparation, coal grinding.Vertical grinding machine mainly consists of powder separator, grinding roller device, grinding disc device, the pressure device, reducer, motor, shell and so on. The separator is a highly efficient and energy saving powder separator. Grinding roller is used to crush and crush materials.
