The Bauermeister counter-rotating pin mill UMP 4.4N Ex has been developed for cocoa pulverising. Between two pinned discs rotating in opposite directions, the cocoa press cake is disagglomerated and crushed.
Opening of the door by linear pulling-out via guide pins
No disassembly of the motors / v-belts when opening the
door, because one motor is mounted on the housing and
one motor on the door
Fast cleaning of the mill interior space thanks to smooth
surfaces Ra < 0.8
Designed as wide chamber housing to minimize accumulations
and prevent blocking of the mill in case of high fat
contents of 22-24 %
Optimum adjustment of pin rows and speed for gentle
grinding of the cocoa press cake at optimum particle fineness
Additional cooling of process air possible via by-pass
The cocoa press cake is centrally fed between two rotating pinned discs via hollow shafts.
The cocoa press cake is fed in on the door side and on the housing side.
By impact and shearing loads the press cake is disagglomerate and crushed between the pins.
Process air and centrifugal forces convey the product through the rotating pinned discs step by step outwards between the pins.
The particle size can be influenced by the speed of the rotating pinned discs.
