Ball mill for graphene production

Abstract

The invention discloses a ball mill for graphene production. The ball mill structurally comprises a motor, a gear, a rotary drum mechanism and a supporting frame, wherein the motor is in threaded fitwith the gear, the gear is fixedly embedded in the outer side of the rotary drum mechanism, the supporting frame is located at the lower end of the rotary drum mechanism, and the rotary drum mechanismis provided with a feeding port, a roller, a rotating mechanism and a discharging port. According to the ball mill, a rotating ring and balls are in fitting rotation, iron balls are clamped on the side faces of stress mechanisms, after the iron balls fall off under the action of gravity, elastic blocks are compressed when the sliding plates are subjected to the action of the iron balls, so that material grinding is prevented from being hindered by vibration generated by springback, the impact force borne by the sliding plates is reduced, the sliding plates are prevented from deforming due toexcessive stress, and the material grinding effect is prevented from being affected by unevenness of the sliding plate; and bending plates are compressed by the gravity of the iron balls, the surfacetension of the friction plates to fit is enhanced, fan-shaped plates is extruded by fixing rings, hollow balls in the middle of connecting plates are compressed by ball blocks, and meanwhile, a slightinertia force is generated under the fitting pressure, so that the fitting gripping force of friction mechanisms to the iron balls is enhanced.

Description

technical field [0001] The invention relates to the field of graphene processing equipment, in particular to a ball mill for graphene production. Background technique [0002] The ball mill adopts the method of rotation, so that the material enters the hollow shaft, and the material is crushed by friction with the rotation of the iron ball. After the gravity is greater than the centrifugal force, the iron ball breaks away from the inner wall of the hollow shaft and rolls down. The ball mill rotates, and the steel ball slides and grinds the material, making the material smaller and smaller, but the impact force of the iron ball throwing is easy to make the material crush on the inner wall of the hollow shaft, so the iron ball is easy to rub and grind with the crushed material at the bottom, The contact area between the iron ball and the inner wall of the hollow shaft is reduced, so that the iron ball does not roll down following the projection of the hollow shaft, which reduc...

[0002] The ball mill adopts the method of rotation, so that the material enters the hollow shaft, and the material is rubbed and crushed with the rotation of the iron ball. After the gravity is greater than the centrifugal force, the iron ball breaks away from the inner wall of the hollow shaft and rolls down. The ball mill rotates, and the steel ball slides and grinds the material, making the material smaller and smaller, but the impact force of the iron ball projectile easily makes the material crushed on the inner wall of the hollow shaft, so the iron ball is easy to rub and grind the crushed material at the bottom, The contact area between the iron ball and the inner wall of the hollow shaft is reduced, so that the iron ball does not roll down following the projection of the hollow shaft, which reduces the effect of crushing materials, and the iron ball impacts the inner wall of the hollow shaft during the throwing process, which easily deforms the inner wall of the hollow shaft.
