Device and method for automatically arraying and uniformly adding grinding media of ball mill

Abstract

The invention discloses a device and a method for automatically arraying and uniformly adding grinding media of a ball mill, and belongs to the technical field of mine preparation equipment. The technical scheme is that the device comprises a storage bin and an arraying bin, a material driving device is arranged in the storage bin, and multi-stage arraying and lifting devices are arranged in the arraying bin at intervals; a material guide step is mounted on the side, far away from the feeding side, of each arraying and lifting device; a feeding port communicating with the storage bin is formed in one side of the arraying bin, and the material driving device extends into the arraying bin through the feeding port and can be in butt joint with the first-stage arraying and lifting device; and an adding device is mounted on the other side of the arraying bin. According to the device, the ore grinding media can be lifted in an array mode, the lifting speed is high, the multi-stage material preparation function is achieved for the arrayed ore grinding media, continuous and accurate adding can be achieved according to needs, and the device is suitable for different types of ore grinding media.

Description

technical field [0001] The invention relates to the technical field of mine beneficiation equipment, in particular to a device and method for automatically arranging and uniformly adding grinding media of a ball mill. Background technique [0002] In the process of mine beneficiation and grinding, the grinding operation is mainly carried out by adding grinding media in the ball mill. The grinding media are mainly steel balls and steel segments. The worn grinding medium is supplemented in the ball mill. [0003] At present, the grinding medium adding equipment is mainly a ball adding machine that can add steel balls. The ball adding machine mainly has a drum type and a chain type. It is equipped with a ball bin and a ball fishing mechanism. The ball fishing mechanism adopts a simple chain or The roller picks up the ball from the bottom or side of the ball storage chamber, and the steel ball needs to roll to the designated fishing opening to get out smoothly. Therefore, only ...

AI Technical Summary

Problems solved by technology

[0003] At present, the grinding medium adding equipment is mainly a ball adding machine that can add steel balls. The main forms of the ball adding machine are drum type and chain type. The roller picks up the ball from the bottom or side of the ball storage bin, and the steel ball needs to roll to the designated fishing port to fish out smoothly, so only standard steel balls can be added, and irregular steel balls and steel segments cannot be added effectively

[0004] In order to add steel balls evenly, it is necessary to grab one steel ball at a time with the ball claw. Due to the irregular arrangement of steel balls in the warehouse, empty fishing often occurs, and it is impossible to add steel balls evenly and accurately; multi-specification steel balls are mixed into storage balls After the warehouse, the ball claws will pick up multiple balls at one time during the ball scooping process; and the balls are easy to jam and block in the ball warehouse, which will eventually cause problems such as discontinuous ball feeding, inaccurate measurement, and high equipment failure rate.
