Abstract
A grinding apparatus having two mulling plates disposed horizontally in superposed relation is provided. The lower mulling plate is connected to suitable drive means for rotating the plate (the direction of rotation is reversed intermittently). The upper mulling plate is eccentrically connected to a support structure and is provided with a guide pin connected at one end to the plate and which extends at the other end through a slot in the support structure. In operation, the lower mulling plate upon rotation effects movement of the upper mulling plate about its eccentric axes, but the extent of travel of the upper mulling plate is controlled or limited by the guide pin which contacts one end or the other of the slot in the support member. The apparatus is useful for grinding pigment and paint.
