Problems solved by technology

[0003] The speed of the projectile wheel is limited by the critical wear speed. When the speed of the projectile wheel reaches a certain value, the friction between the mineral material and the projectile wheel will cause the wear of the projectile wheel to rise sharply, and the projectile wheel will be scrapped in a short time
[0004] Although the impact speed of the multi-rotor counter-impact mill is double that of the single-rotor self-impact mill, the effective impact rate of the ore is greatly reduced

Embodiment Construction

[0018] Such as figure 1 with 2 As shown, the double-wheel coaxial differential self-impacting mill of the present invention mainly includes a frame 1, and also includes a coaxial projecting wheel 2 and self-impacting wheel 5, the self-impacting wheel main shaft 6 is a hollow shaft, and the projecting wheel Main shaft 3 is placed in the hollow shaft, therefore, the projecting wheel is inside, and the self-beating wheel is outside. The inner side of the upper end of the hollow shaft and the upper end of the main shaft of the projecting wheel are installed and fixed with high-speed bearings to ensure the stability of the two shafts when rotating, and the upper and lower ends of the outer side of the hollow shaft are vertically installed in the center of the frame with bearings. The projecting wheel is fixedly installed on the projecting wheel main shaft upper end with a straight key connection bolt, and the projecting wheel main shaft lower end is installed on the base with a be...

Abstract

The invention discloses a double-wheel coaxial differential self-impacting type grinder. The double-wheel coaxial differential self-impacting type grinder mainly comprises a rack and also comprises a throwing wheel and a self-impacting wheel which are coaxial, wherein the throwing wheel is arranged inside and the self-impacting wheel is arranged outside. The inventor adopts an ingenious coaxial mode for combining the throwing wheel and the self-impacting wheel together, and self-impacting grinding operation is realized by double-wheel coaxial differential movement. Since the throwing wheel and the self-impacting wheel rotates reversely on the same horizontal plane, the rotating speed of the self-impacting wheel can be increased substantially without limitation as long as the rotating speed of the throwing wheel is effectively controlled according to the critical wear speed, so that high-speed impact of ore materials is realized and the ore-material breaking efficiency is improved.

Description

technical field [0001] The invention belongs to the field of mineral crushing equipment, in particular to a double-wheel coaxial differential speed self-impact pulverizer. Background technique [0002] Non-metallic ore grinding equipment mainly includes ball mills, Raymond mills, vertical mills, etc., all of which adopt the principle of rolling crushing. In the past ten years, the single-rotor self-impact and multi-rotor counter-impact mills that have appeared all adopt the principle of impact crushing, that is, the higher the material ejection speed, the greater the impact kinetic energy, and the better the crushing effect. However, whether it is a single-rotor self-impact mill or a multi-rotor counter-impact mill, there are the following deficiencies: [0003] <1> The speed of the projectile wheel is limited by the critical wear speed. When the speed of the projectile wheel reaches a certain value, the friction between the mineral material and the projectile wheel w...
