You can remove the interior hopper to feed in the material to be ground. The 8-rib-rotor is also suitable for pre-crushing (or coarse crush- ing). To do so, it is operated with the sieving ring substitute (no. 44.1110.00) and possibly without the interior hopper as well. pulverisette 14 Page 10... -

5. Lid (the centre disc in the middle of the lid must line up with the centre of the sieving ring) The machine may only be operated when all parts have been fitted. If parts are forgotten, damage to the machine can re- sult. pulverisette 14 Page 12... - Page 16 The smaller the internal diameter, the lower the noise levels when grinding. Caution: when opening the hood, the small interior hopper can fall out to the rear when the hood is fully opened. pulverisette 14 Page 13...

The finer the sieve perforation is, the longer the grinding time; finer perforation reduces the noise level. Cooling Good cooling (e.g. by using the filter system or material suction) always has a positive effect on grinding and mill. pulverisette 14 Page 18... -
