    摘要: A two-shaft shredder includes a shredder housing, a first cutter disc unit, and a second cutter disc unit. The first cutter disc unit has at a first axial end a first bearing unit (80) with a first bearing housing and at a second axial end a second bearing unit with a second bearing housing. A first cutter disc block is rotatably mounted about a first axis of rotation. The second cutter disc unit has at a first axial end a third bearing unit with a third bearing housing and at a second axial end a fourth bearing unit with a fourth bearing housing A second cutter disc block is rotatably mounted about a second axis of rotation. The shredder housing has a first maintenance hatch cover which, in a release position, permits removal of the first cutter disc unit together with the first and second bearing units.

    摘要: A novel device for hand grinding coffee is disclosed. The device preferably includes a base, a stanchion disposed about the base, and a gear box, a burr collar, and a flywheel each extending away from the stanchion. The flywheel includes a handle for turning it. The device further includes a gear mechanism including a main driven shaft. The main driven shaft extends downward from the gear box. There also is a burr mechanism driven by the gear mechanism. The device may include a variable transmission mechanism having a first gear set and a second gear set selectively engageable to drive the main driven shaft. The device may also include a tumbler having a ground chamber. A distribution member is configured to rotate within the ground chamber of the tumbler during operation of the device.
