Double-motor self-synchronous driving vibration ball mill

Abstract

The invention belongs to a grinding device, and provides a double-motor self-synchronous driving vibration ball mill. The system adopts a structure that the center of a cylinder body is eccentric witha power main shaft, the cylinder body is used as an excitation body, the mass moments of two vibration exciters are different, and m1r1 is larger than m2r2; the two vibration exciters are symmetrically installed relative to the center of a roller, the connecting line of rotating centers of the two vibration exciters is in a beta angle with the horizontal direction (beta is equal to 0-90 degrees),and the vibration exciter with the large mass moment is arranged on the left upper part; and meanwhile, the installation of the vibration exciters meets a certain position conditions, when the systemis operated stably, two motors achieve synchronization and operate stably, the steering is the same, and the phase difference is stable to be close to Pi. At the moment, the motion mode of the rolleris in the coexistence of swing and circular motion, due to the fact that the phase difference is close to Pi, so that swing occupies the main part. Ball milling medium in the roller is continuously thrown away under the action of the combined movement of swinging and the circular motion, the ball milling medium roll from a high position to a lower position, a high-strength rolling impact effect is generated, and ball milling of the materials is realized.

Description

Technical field [0001] The invention belongs to a ball mill device, and is specifically a dual-machine self-synchronous drive vibrating ball mill. Background technique [0002] The ball mill is the key equipment for further grinding of materials after crushing. It is widely used in mineral processing, building materials and chemical industries. For example, in the beneficiation industry, when useful minerals are distributed in granular form in the ore, in order to separate the gangue in the ore and separate various useful minerals from each other, the ore must be ground to 0.1-0.3 mm by a ball mill. Sometimes it is ground to below 0.05 to 0.07 mm. In order to realize the grinding process, crushing media of various diameters (steel balls, steel rods, gravel, etc.) are generally loaded into the cylinder to form a strong impact on the material and complete the grinding effect. Since the metal recovery rate and output have a great relationship with the fineness of ore grinding, imp...
