Problems solved by technology

[0003] However, this vibrating ball mill has large vibration and noise, and the ball is thrown out by vibration, which has a relatively large impact on the electrode rod.
In addition, the existing roller ball mill has small input mechanical energy and relatively low ball milling efficiency. In order to further improve the ball milling efficiency, auxiliary technology is needed to strengthen the ball milling process, and the direct introduction of plasma assistance needs to solve the difficult problem of mutual interference between the electrode shaft and the roller rotation

Embodiment Construction

[0014] The present invention is further described in detail through the following embodiments and accompanying drawings. However, embodiments of the invention are not limited thereto.

[0015] Such as figure 1 As shown, the plasma-assisted high-energy roller milling device consists of an electrode shaft 1, a roller body 2, a large ring gear 3, a bearing seat upper cover 4, a bearing seat end cover 5, a bearing seat 6, a speed regulating motor 7, a pinion 8, and a roller Body cover 9, sealing ring 10, small bearing 11, large bearing 12, and power supply 13; their connection relationship is as follows: in the center of the traditional roller ball mill, a fixed electrode shaft 1 is installed through the end cover of the bearing seat, and the electrode shaft 1. It is coaxial with the drum body 2 and is movably connected to each other through the small insulating bearing 11. The sealing ring 10 is embedded in the small bearing 11 in the journal hole of the drum body to assemble it...

Abstract

The present invention provides a high-powered ball grinding technology, specifically a plasma assisting high powered roller ball grinder. The device is changed on the base of traditional roller ball grinder, specifically an electrode axis having a coaxial-line with the roller mounted and fixed by bearing base lid in the roller ball grinder. The aim of the introducing plasma to the roller ball grinder by the device is achieved, the ball grinding speed is accelerated, the diameter distribution is narrow, the grinding efficiency is effectively enhanced at the same time. The device overcomes the deficiency of high vibration and noise of plasma assisting high powered roller ball grinder. The device of the invention has a simple structure, reasonanle and easy to prepaation, the method is easy to achieve, and the device also effectively pushes the application and popularization of the plasma assisting high powered roller ball grinder in the large-scale production in batch of the micronano.

Description

technical field [0001] The present invention relates to high-energy ball milling technology, and more specifically refers to a device for plasma-assisted high-energy roller ball milling. Background technique [0002] High-energy ball milling technology is one of the important technologies for preparing micro-nano powders, and is widely used in the fields of micro-nano powder preparation and mechanical alloying. High-energy ball milling technology is a process of imposing energy on the powder to be processed. However, the existing high-energy ball mills mainly use the mechanical energy of the balls in the ball milling pot to grind the powder by simply rotating or vibrating the ball milling pot. The processing efficiency is not high, so The processing time of the ball mill becomes longer, and the synthesis of some products requires hundreds of hours, which in turn causes serious pollution of the product powder by the ball mill. It is for these reasons that the ordinary high-e...
