Patent DE-3121937-A1 (DE)
Title: Mill sifter
Inventor: BACHARACH OTTMAR
IPC: B02C13/14
Filed: 1981-06-03
Abstract: In vertical mills with a central inlet pipe and a sifter arranged in the upper region of the mill housing, difficulties are experienced in conjunction with the bearing of the blade wheel of the sifter if such a wheel is present and it is not a static sifter. In particular, this bearing has to be protected against the high temperature which prevails in the mill housing and against any contamination. According to the present proposal, this is achieved in that the blade wheel is suspension mounted only by the upper end of its hollow shaft which surrounds the central inlet pipe and this bearing is cooled with sealing air which is fed by a blower and is also protected by means of this sealing air, which emerges into the mill space at the lower end of the hollow shaft through a gap seal, against dirt which enters therefrom. <IMAGE>
