Ore screening device for mining industry

Abstract

The invention discloses an ore screening device for the mining industry. The ore screening device comprises a machine body and a base table. One side of the machine body is fixedly connected with the base table. A transverse plate is fixedly connected with the position, away from one side of the base table, of one side of the top of the machine body. A supporting mechanism is connected between one side of the transverse plate and one side of the base table and comprises a connecting shaft, a supporting rod and a fixed block. The outer surface of the connecting shaft is fixedly connected with a roll cage through the supporting rod. According to the ore screening device, ore raw materials can be pushed by screw advancing pushing force generated during high-speed rotating of a screw blade to be screened on a screen, ore subjected to screw screening is subjected to rotating and stirring screening again through the rotating and stirring effect generated by the supporting rod and the roll cage, and therefore two kinds of screening operation of screw pushing screening and rotating and stirring screening are carried out on the ore, the ore screening effect and screening efficiency are improved to a large degree, and ore utilization is facilitated.

Description

Technical field [0001] The invention relates to the field of mining equipment, in particular to an ore screening device for the mining industry. Background technique [0002] The mining industry refers to the extraction of natural minerals such as solids (such as coal and minerals), liquids (such as crude oil) or gases (such as natural gas). Including underground or above-ground excavation, operation of mines, and all auxiliary tasks for processing raw materials generally performed at or near the mine site, such as milling, beneficiation and processing, are all activities in this category. It also includes the preparation work required to make the raw material available for sale. But it does not include water storage, purification and distribution, as well as geological survey and construction engineering activities. [0003] Nowadays, when mining ore, it is necessary to screen and process the mined ore raw materials. Usually, the equipment for screening treatment is an ore scree...
