A mining material screening device

Abstract

The invention belongs to the technical field of mineral material processing, in particular to a mineral material screening device. Aiming at the large quality of mineral material, large kinetic energy is generated when falling from a high place, and its long-term impact and erosion will also cause irreparable damage to the interior of the equipment. wear and tear, so part of the internal structure of this type of equipment needs to be replaced or maintained regularly, and the durability is poor. The following scheme is proposed, including the screening box, the top inner wall of the screening box is fixed with a base block by screws, so One side outer wall of the base block is fixed with a long axis by screws. In the present invention, through the provided slide plate, convex strip and tension spring, the mineral material contacts the slide plate when it slides down, and the friction force with the mineral material is increased under the action of the convex strip, so that the slide plate is pulled out, and the tension spring drives the slide plate to recover, so The function makes the sliding plate produce reciprocating extraction and recovery dynamics, which can effectively offset the kinetic energy of the falling mineral materials, reduce the impact force when falling, and improve the durability of the machinery in the device.

Description

technical field [0001] The invention relates to the technical field of mineral material processing, in particular to a mineral material screening device. Background technique [0002] Due to the large-scale development and utilization of mineral resources, the amount of available resources has been continuously reduced, resulting in a decline in the quality of raw ore mining, and subsequent processing such as smelting has also increased the quality requirements of mineral processing products. Therefore, it is necessary to use beneficiation equipment to screen the mined ores. [0003] In the process of mineral material screening, it is necessary to pour the mineral material from the top of the screening equipment into the screening equipment. Although the internal mechanism of this type of screening equipment is made of rigid materials with high strength, due to the high quality of the mineral material, Large kinetic energy is generated when falling from a height, and its lo...

Problems solved by technology

[0003] In the process of mineral material screening, the mineral material needs to be poured into the screening equipment from above the screening equipment. Although the internal mechanism of this type of screening equipment is set to be made of strong rigid materials, due to the large quality of the mineral material, Large kinetic energy is generated when falling from a high place, and its long-term impact and erosion will also cause irreparable wear and tear on the inside of the equipment. Therefore, some internal structures of this type of equipment need to be replaced or maintained regularly, and the durability is poor.
