Abstract
The invention discloses a graded grinding bead mill, which comprises a rotor column and a stator cylinder, with the rotor column positioned in the stator cylinder. A connecting shaft at the upper end of the rotor column pierces the top surface of the stator cylinder and is in external connection with a motor. Several annular sieving devices with different meshes are disposed inside a grinding cavity, and the number of the annular sieving devices located below is larger than the number of the annular sieving devices located above. The several annular sieving devices divide the grinding cavity into several sub-grinding cavities from top to bottom, and a feed inlet is communicated with a sub-grinding cavity at the top of the grinding cavity. The bottom of the stator cylinder is provided with an outlet, and a bottom sieving device is arranged above the outlet, so that materials can be grinded by a plurality of sub-grinding cavities from top to bottom in order and materials of different particle size ranges can be located in different sub-grinding cavities for grinding, thus being in favor of grinding efficiency improvement. When all sub-grinding cavities can discharge, materials of different particle size ranges can be grinded out.
