Abstract

A resonance mill is designed according to the resonance principle and is grinding equipment used for smashing a grinding material to fine particles. The resonance mill is composed of a grinding cylinder, a resonance spring, a resonance rack, vibration exciters, a damping spring, an engine base and motors. The grinding cylinder and the resonance rack are connected through the resonance spring. The vibration exciters are positioned on the resonance rack and are driven by the motors to rotate so as to produce vibration. The grinding cylinder and the resonance rack are connected on the engine base through the damping spring. The spring can be a steel spring, a rubber spring, an air spring or a composite spring, and the form can be composed of multiple springs. The vibration exciters and the motors can be replaced with vibration motors. There might be two or more vibration exciters and motors. There might be one or more grinding cylinders. By the utilization of the resonance principle, great vibration can be produced by a small force. Thus, mechanical efficiency of the equipment is greatly enhanced, energy can be saved by at least 50%, and the effect is remarkable.

Description

Co-vibration mill

Technical field:

The present invention relates to a kind of vibratory equipment, be the co-vibration mill utilizing resonance principle to design.Belong to " mill of band vibrator " technical field in International Classification of Patents B02C19/16 reducing mechanism.

Background technology:

Vibrant pulverization equipment advantage be that energy consumption is low, grinding particle size is thin.The co-vibration mill of the present invention is higher than common vibromill reliability, can obtain big vibrational energy with less exciting force, and smashing fineness is thinner simultaneously, and energy consumption is lower.The advantage making vibrant pulverization more can play.At breeze, coal, cement, the industry such as pottery is widely used.

Summary of the invention:

The purpose of the present invention, improves the performance of vibrating mill, than the mill machine energy-saving more than 50% of same volume.

The principle of foundation of the present invention: co-vibration mill produces dither by inertia vibration generator, and sand cylinder produces resonance in the case of frequency ratio is close to 1.And carry out three-dimensional circle frequency vibration with the frequency of nearly 50 hertz.Vibrational energy is by the incoming cylinder of sand cylinder, and produces high-speed rotational energy field in cylinder, and the acceleration power of energy field can reach 45g (General Oscillation disintegrating apparatus only has 10g).Medium and material is made to do high speed gyration along barrel.Simultaneously because the effect of centrifugal force, in cylinder, the medium of center and material are extruded to barrel by interior again, form centrifugal force field.Medium and material produce eddy current shape irregular movement under the effect in the dual field of force.Material is impacted by higher than excited frequency tens times at the volley, is sheared, is extruded, abrasive action, constantly refines decomposition, finally gives micron order or nano-scale particle.

Technical scheme is as follows.

A kind of co-vibration mill is made up of sand cylinder, resonant spring, resonance frame, vibrator, damping spring, support, motor.It is connected by resonant spring (2) between sand cylinder (1) with resonance frame (3).Vibrator (7) is positioned on resonance frame, and vibrator is rotated generation vibration by motor (8).Sand cylinder and resonance frame are connected on support (6) by damping spring (5).Spring can be steel spring, rubber spring, air spring, complex spring, and its form can be made up of multiple springs.Vibrator and motor can be replaced by vibrating motor (4).The quantity of vibrator and motor can be two, it is also possible to is multiple.The quantity of mill tube can be one, it is also possible to is multiple.

The beneficial effects of the present invention is: co-vibration mill utilizes resonance principle, use less strength to produce bigger vibration.The mechanical efficiency of equipment be greatly improved, the most energy-conservation 50%.Ore grinding cost is reduced in ore grinding, significant in reality produces.Can do ultra micro, superfine grinding, granularity can reach micro/nano level simultaneously.

Detailed description of the invention:

Embodiments of the present invention.The first vibrating motor replaces vibrator and motor as power source.Vibrating motor i.e. the motor of band vibrator, vibrating motor is positioned at the both sides of resonance frame, and symmetry also occurs, such more compact structure in pairs.Such as Fig. 1.The second embodiment, by vibrator and motor as vibration source, vibrator is positioned at resonance frame both sides, and symmetrical also occur in pairs.Motor is coupled with vibrator by power transmission shaft.Such as Fig. 2.The quantity of the third embodiment, vibrator and motor can be two, it is also possible to is multiple.The quantity of mill tube can be one, it is also possible to is multiple.
