Magnetic-vibration swing-impact-type ball milling device

Abstract

The invention relates to a magnetic-vibration swing-impact-type ball milling device which includes: a pedestal; a door-shaped support arranged vertically thereon; two cantilevers which are fixed on the top of the door-shaped support in horizontal direction; an electromagnetic coil arranged below the two cantilevers and on the door-shaped support; an AC frequency converter electrically connected to the electromagnetic coil; and a cylindrical vibrator unit inserted in the electromagnetic coil, wherein two ends of the cylindrical vibrator are connected to the two cantilevers through pulling ropes respectively, so that a floating reciprocating movement system is configured by means of the cylindrical vibrator unit, the pulling rope, the electromagnetic coil and the cantilevers. When the device works, the AC frequency converter controls the electromagnetic coil to generate an alternating magnetic field, and the cylindrical vibrator unit reciprocatingly moves under the effect of the alternating magnetic field. Compared with the prior art, by means of the movement system driven by magnetic force, the system has no mechanical transmission parts, is low in movement resistance and mechanical noise, is convenient to operate, clean and maintain, is safe and reliable, has long service life, and has great application prospect.

Description

technical field [0001] The invention belongs to the technical field of material crushing equipment, and relates to a ball mill, in particular to a magnetic vibration swing impact ball mill. Background technique [0002] In industrial production and laboratory sample preparation, it is often necessary to pulverize certain materials. The ball mill is a commonly used equipment for crushing after the material is crushed. Existing ball mills generally use the centrifugal force during rotation to elevate the steel balls inside, and crush the materials through the interaction between the steel balls and the materials. The sphere is generally made of metal or non-metallic materials, and rotates with the cylinder of the ball mill, making repeated movements such as turning, throwing, rolling, sliding, etc. in the cylinder, and achieves crushing and grinding through the impact and friction with the material. The purpose of crushing and crushing materials. [0003] At present, the ex...

AI Technical Summary

Problems solved by technology

The technical solution disclosed in the above-mentioned patent mainly adopts the single-rod swinging motion method, which requires the structural design of the eccentric wheel. Although it can improve the ball milling efficiency, the structure of the mechanical transmission parts is relatively complicated, and there are still serious mechanical wear problems between the parts.
