Problems solved by technology

[0007] The present invention aims at the current problems that the rotating shafts at both ends of the ball mill barrel exert a large pressure on the bearings during the operation of the ball mill, and the friction between the shaft and the bearings is large, and energy consumption is high, resulting in short service life of the bearings and high maintenance costs. A ball mill includes a bracket, a rotating shaft, a ball mill cylinder, a bearing, a reducer, and a motor. The ball mill cylinder is rotatably fixed on the bracket through the rotating shaft and the ball mill bearing, and also includes a magnetic component, which mainly includes Magnetic force group, the magnetic force group and the ball mill cylinder correspond to each other

Embodiment 1

[0022] like figure 1 As shown, a ball mill includes a bracket, a rotating shaft, a ball mill cylinder O, a bearing, a reducer and a motor, and the ball mill cylinder O is rotatably fixed on the bracket through the rotation shaft and the ball mill bearing, and also includes a magnetic component. The magnetic force assembly includes a magnetic force group 2 and a fixed support 1. The magnetic force group 2 is fixed on the fixed support 1. Since the other ball mill components are the same as those commonly used at present, they are not marked in the figure. Utilizing the attractive force of the magnetic field on the magnetically permeable material (the ball mill cylinder is generally made of magnetically permeable steel), the magnetic force group 2 carried by the fixed bracket 1 above the ball mill cylinder 0 and the ball mill cylinder 0 generate a magnetic force that attracts each other, Furthermore, an upward pulling force is generated on the entire ball mill cylinder 0, so tha...

Embodiment 2

[0026] like figure 2 As shown, a ball mill includes a bracket, a rotating shaft, a ball mill cylinder O, a bearing, a reducer and a motor, and the ball mill cylinder O is rotatably fixed on the bracket through the rotation shaft and the ball mill bearing, and also includes a magnetic component. The magnetic force assembly includes a magnetic force group 2 , a force receiving ring 3 and a fixed bracket 1 , and the magnetic force group 2 is fixed on the fixed bracket 1 . The magnetic force groups 2 are two groups, and they are respectively arranged on the upper part and the lower part of the ball mill cylinder 0 . Both the magnetic force group 2 and the force ring 3 are integrated with permanent magnetic materials and magnetic permeable materials in this embodiment.

[0027] The force receiving ring 3 fixed on the ball mill cylinder 0 is simultaneously affected by the magnetic force group 2 on the upper part of the ball mill cylinder 0 and the lower magnetic force group 2 . T...

Embodiment 3

[0032] like image 3 As shown, a ball mill includes a bracket, a rotating shaft, a ball mill cylinder O, a bearing, a reducer and a motor, and the ball mill cylinder O is rotatably fixed on the bracket through the rotation shaft and the ball mill bearing, and also includes a magnetic component. The magnetic force assembly includes a magnetic force group 2, a force ring 3, a magnetic isolation layer 4 and a fixed bracket 1. The magnetic force group 2 is fixed on the fixed support 1 and is above the ball mill cylinder, and also includes a force ring 3. The force ring 3 is fixed on the outer wall of the ball mill cylinder 0 and is arranged corresponding to the magnetic force group 2 . The force ring 3 is made of magnetically conductive material, and the magnetic force group 2 is used to generate magnetic attraction force on the magnetic material. Permanent magnetic materials or DC coils that generate magnetic fields can also be installed in the force ring, using the principle of ...

Abstract

The invention relates to ore grinding equipment, in particular to a ball grinding machine, and aims to solve the problems of short service life of bearings and high maintenance cost which are caused by large pressure applied by shafts at two ends of a cylinder of the conventional ball grinding machine, large friction between the shafts and the bearings, and high energy consumption in the conventional ball grinding machine in the running process. The ball grinding machine comprises a support, a rotation shaft, a ball grinding cylinder, bearings, a reduction gear and an electric motor; the ball grinding cylinder can be rotatably fixed on the support through the rotation shaft and the bearings of the ball grinding machine; the ball grinding machine also comprises magnetic assemblies; each magnetic assembly mainly comprises a magnetic group; and therefore, the ball grinding cylinder is suspended by magnetic force, the pressure applied by the shafts at two ends of the ball grinding cylinder to the bearings can be effectively eliminated or reduced, the friction between the shafts and the bearings can be reduced or eliminated, energy consumption is saved, the service life of the bearings is prolonged, and the maintenance difficulty and cost of the bearings are reduced.

Description

[0001] technical field [0002] The invention relates to a grinding equipment, in particular to a ball mill. [0003] Background technique [0004] Ball mill is the key equipment for crushing materials, widely used in cement, ceramics, building materials, refractory materials, chemical fertilizers, ferrous and non-ferrous metal beneficiation and glass and other production industries. The ball mill is mainly composed of a ball mill cylinder and a transmission system. The transmission system drives the ball mill cylinder to rotate at an appropriate speed, so that the materials in the cylinder are impacted and ground by the grinding body (generally steel balls, steel segments, ceramic balls, etc.) fine particles. [0005] The ball mill barrel of the ball mill, the grinding body in the ball mill barrel, and the materials to be ground are all relatively heavy items, and the ball mill needs to rotate continuously in the working state, so the load required by the ball mill in the...
