Screening device for wear-resisting ball machining

Abstract

The invention discloses a screening device for wear-resisting ball machining, and relates to the technical field of wear-resisting ball production. The screening device for wear-resisting ball machining comprises an inner roller screen and an outer roller screen; the inner surface of the inner roller screen is fixedly connected with a transmission shaft through a connecting rod; first screen holesare arrayed in the peripheral side surface of the inner roller screen; external threads are arranged on the peripheral side of the transmission shaft; the inner surfaces of the two ends of the outerroller screen are fixedly connected with a first connecting sleeve and a second connecting sleeve through connecting rods correspondingly; and the first connecting sleeve is connected with the transmission shaft through an adjusting sleeve. According to the screening device for wear-resisting ball machining, the inner roller screen and the outer roller screen which can be in sliding fit with eachother are arranged, and the size of a screen mesh is changed through utilizing mutual dislocation between the first screen holes and second screen holes, so that the problems that screen equipment cannot adapt to screening of multi-size wear-resisting balls and consequently is poor in adaptability are solved; and meanwhile, through mutual dislocation adjustment between the first screen holes and the second screen holes, the wear-resisting balls clamped in the screen holes can be effectively removed, and the problems that the production efficiency and the production cost are influenced due to the fact that manual cleaning is needed can be solved.

Description

technical field [0001] The invention belongs to the technical field of wear-resistant ball production, in particular to a screening device for wear-resistant ball processing. Background technique [0002] Wear-resistant ball is a kind of crushing medium used in ball mills, which is used to crush the materials in the mill. Different ball mills and different industries have different requirements for the size of wear-resistant balls. Therefore, wear-resistant balls need to be screened and classified according to size after processing. [0003] The wear-resistant ball sorting and testing equipment in the prior art can only screen out wear-resistant balls of a certain size in one screening, and the adaptability is poor. However, when there are wear-resistant balls of various sizes in the wear-resistant balls to be screened, multiple screenings and screening equipment of different sizes are required to thoroughly screen wear-resistant balls of different sizes, resulting in low s...
