FIELD: process engineering.SUBSTANCE: invention relates to grinders and to cleaning of grinder from foreign body. System 100 comprises at least one bidirectional cylinder 70 to maintain constant grinding force between head 500 and bowl 400 and to make cleaning stroke that facilitates the foreign body passage. Body of at least one cylinder 70 is reliably secured to main housing 300 at self-centring self-aligning position with the help of cylinder holder 40. Piston rod 30 of at least one cylinder 70 is directly or indirectly reliably coupled with adjusting ring 200 at self-centring self-aligning position. Piston rod 30 comprises first fastening link 10 and second link 20. Fastening part 202 integrated with adjusting ring 200 is caught between first and second fastening links 10, 20 of piston ring 30.EFFECT: higher efficiency.18 cl, 6 dwg |
