Ore screening machine for mines

Abstract

The invention relates to the technical field of ore screening machines, and discloses an ore screening machine for mines. The ore screening machine comprises a screening box, wherein sliding rails areinstalled at the upper end of the inner wall of the screening box, a pulley is slidably arranged on each sliding rail, a supporting column is installed at the upper end of each pulley, a crushing motor is installed at the upper end of the left supporting column, and an output shaft of the crushing motor is connected with a crushing shaft; the other end of the crushing shaft is rotationally arranged on a fixing block fixed to the right side supporting column, a filter plate is installed between the middles of the supporting columns, a supporting spring is installed between the right supportingcolumn and the inner wall of the screening box, a fixed magnetic block is installed at the left side of the left supporting column, and an electromagnetic block is installed at the opposite positionof the left side of the fixed magnetic block; and an upper screen plate and a lower screen plate are hinged to the inner wall of the lower end of the screening box. According to the ore screening machine, left-right swinging of the filter plate is achieved, the primary crushing processing effect on ores is ensured, and left-right shaking discharging can be achieved; and meanwhile, the ores can bescreened multiple times, and the screening precision of the ores is greatly improved.

Description

technical field [0001] The invention relates to the technical field of ore screening machines, in particular to an ore screening machine for mines. Background technique [0002] Mine refers to an independent production and operation unit that extracts ore with a certain mining boundary. Mine mainly includes one or more mining workshops (or pitheads, mine shafts, open pits, etc.) and some auxiliary workshops, and most mines also include ore dressing plants (coal washing plants). [0003] Ore refers to mineral aggregates from which useful components can be extracted or which have certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are usually expressed in percentages. The ore grade is often used to measure the value of ore, but the composi...

Problems solved by technology

[0005] The current ore screening machine only has a single filtering function, which is inconvenient to take out the screened ore, which makes the working efficiency of the equipment low. The ore screening machine in the first stage cannot meet people's needs very well

[0006] Chinese patent (notification number: CN211436974U) discloses a mining ore screening machine, including a casing, a rack and a fixed block, the left side of the casing is provided with an ash outlet, and the front and rear sides of the ash outlet are provided with rotary handle, the right side of the housing is fixed with a support plate, and a screw is arranged above the support plate, a motor is installed above the screw, and an incomplete gear is arranged at the front end of the motor, and the rack is located at the center of the incomplete gear. A filter plate is installed above the rack, and a baffle is fixed above the filter plate, and a damping rod is installed on the left side of the baffle, although this device can realize the filtering and screening of ore to a certain extent , but in actual operation, the initial ore cannot be effectively processed, resulting in low screening accuracy in the later stage. Therefore, further improvement is still needed
