Powder mill production device - has system of vacuum exposed bearings and planetary drive gears

摘要

The device is for production of powder under vacuum or under a protective gas atmosphere. A drive shaft is coupled to the milling container by means of a carrier arm within a mill housing attached to a vacuum system. The drive shaft is mounted in bearings connected to a lubricant filled space and connected to an external drive motor. The bearings and lubricant space form a bearing body which can be evacuated like the remainder of the mill housing. A gear system connects the milling container by means of a planetary gear wheel drive and each milling container has an individual sealing cover.
