Description

Technical Field

[0001] The utility model relates to the technical field of ore processing, and particularly relates to an ore screening device for ore processing in a mine. Background Technique

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which itself has certain utilizable properties. 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 commonly expressed in percentages. Ore grade is commonly used to measure the value of ore, but the composition of gangue (useless minerals in ore or minerals with very little useful component content that cannot be utilized) and the amount of harmful impurities in ores with the same effective components also affect the value of ore, so ores need to be screened.

[0003] According to the patent with the Chinese patent publication number CN 209318153 U, an ore rapid screening device is disclosed. The technical problem to be solved is: to provide an ore rapid screening device with uniform vibration and convenient separation. The technical solution of the utility model is: an ore rapid screening device, including a base, a left support, a right support, a screening box, a screen, a funnel, a mounting plate, etc.; the left support is symmetrically arranged front and back on the left side of the top of the base, the right support is symmetrically arranged front and back on the right side of the top of the base, the left part of the screening box is hinged between the upper sides of the two left supports, and a mounting plate is connected between the upper parts of the right supports. The utility model drives the second bevel gear to rotate through the first motor, the second bevel gear drives the rotating shaft to rotate through the first bevel gear, the rotating shaft drives the disc to rotate, the disc drives the screening box to swing up and down through the connecting rod, and then the ores on the screening box roll back and forth, and then the ores of different sizes are quickly and effectively sorted out.

[0004] However, this screening device can only screen ores once, with poor screening effect and weak practicability. At the same time, dust is easily generated during the feeding and screening processes, affecting the health of workers and polluting the air. Therefore, dust reduction is required. For this reason, we propose an ore screening device for ore processing in a mine. Content of the Utility Model
