Description

Ball material separator of superfine grinding device

Technical Field

The utility model relates to a production of metal powder, concretely relates to superfine grinder ball material separator.

Background

In the system, the powder material in the grinding machine is carried out of the grinding machine under the driving of circulating gas, and the separation of the circulating gas and the processed powder is completed through two-stage dust collection devices of a cyclone dust collector and a cloth bag dust collector. In order to prevent the grinding medium and the powder material in the grinding machine from being mixed together and being taken out of the grinding machine by the circulating gas, a screen plate with a mesh diameter slightly smaller than the diameter of the grinding medium is usually added at the outlet of the grinding machine, because the particle diameter of the processed powder material is far smaller than the diameter of the grinding medium, the screen plate can block the grinding medium in the grinding machine, and the processed powder material can smoothly pass through the screen plate, thereby achieving the purpose of ball material separation. However, when the diameter of the abrasive medium is small or the amount of the abrasive medium is small, the abrasive medium may be adsorbed on the mesh plate by the circulating air flow, resulting in a discharge failure.

According to the production characteristics of the superfine metal powder, in a negative pressure circulating discharging system protected by inert gas, a device capable of replacing a discharge port screen plate of a grinding machine and automatically separating balls and materials in the grinding machine in a closed circulating discharging system is designed, and the device for better solving the problems of separation of small-diameter or small-mass grinding media and processed powder materials and automatic backfilling of the grinding media is well solved.
