Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of ore dressing screening, and specifically relates to a cylindrical ore dressing screening machine. BACKGROUND

[0002] The working principle of the cylindrical ore dressing screening machine is based on the combined action of gravity and centrifugal force generated by the rotation of the cylinder on the material in the cylinder. The material moves along the circumferential path in the cylinder. Due to the inclination angle in the cylinder, the material gradually moves downward. In this process, the material passes through the screen mesh and is divided into different grades according to the particle size, and is discharged from different outlets of the cylinder. Generally, the cylinder of the cylindrical ore dressing machine is placed at a certain inclination angle. Compared with the horizontally placed cylinder, the cylinder placed at an inclination angle has greater friction loss between the cylinder and its support structure. Therefore, the utility model provides a cylindrical ore dressing screening machine. SUMMARY

[0003] The utility model aims at providing a cylindrical ore dressing screening machine to solve the problems in the background art.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical scheme.

[0005] Preferably, the rotating drum is provided with an inner screen mesh and an outer screen mesh, the inner screen mesh and the outer screen mesh are hollow truncated cone-shaped, and a plurality of support rods are arranged between the inner screen mesh and the outer screen mesh.

[0006] Preferably, the size of the screen holes of the inner screen mesh is larger than that of the outer screen mesh, and the inclination directions of the inner screen mesh and the outer screen mesh are opposite.

[0007] Preferably, a discharge bin is arranged below the rotating drum on the support frame, and a slot is formed in the support frame and communicates with the space between the inner screen mesh and the outer screen mesh.

[0008] Compared with the prior art, the utility model has the beneficial effects that the rotating drum is supported by the support wheels arranged on the support frame, and the rotating drum is rotated by the motor, so that the inner screen mesh and the outer screen mesh in the rotating drum are arranged at an inclination, and the material can slide under the action of its own gravity. The rotating drum is placed horizontally on the support frame, thereby reducing the friction loss. BRIEF DESCRIPTION OF DRAWINGS
