b: after the step A is completed, the electromagnet is intermittently electrified and magnetically connected with the fixed magnet, so that the inner sliding block is driven to slide in the inner cavity, the sliding sleeves at two sides of the inner sliding block slide on the outer surface of the sliding column, and meanwhile, the inner cylinder body in the outer cylinder body is vibrated at high frequency in the rotating process under the action of the vibrating spring, so that the steel ball is collided with the graphite material in the outer cylinder body at high efficiency, the shape of the material is quickly trimmed, and the materials are uniformly mixed;
c: when the step B is completed, the infrared transmitter is connected with the infrared receiver through the optical path, the controller controls the electromagnet to be electrified intermittently, the electromagnet is electrified intermittently to attract the steel ball, the electromagnet is positioned right above the roller mechanism, so that the steel ball can quickly approach the highest point inside the inner cylinder, larger gravitational potential energy is obtained, after the electromagnet is powered off, the steel ball loses the attraction of magnetic force, so that the heavy impact and grinding effect of the steel ball on materials are enhanced, and meanwhile, the situation that caking generated by mixing of the materials and liquid is attached to the inner surface of the inner cylinder is reduced by high-frequency vibration of each part of the inner cylinder, so that the grinding quality is enhanced.
