The present invention relates to a method to grind mass in a grinder (1) wherein the mass is provided to the grinder (1) via a hopper (5) and transported by a feeder worm (2) to a rotating processing worm (3) which conveys the mass towards a cutting set (4) which grinds the mass and wherein the feeder worm (2) initially rotates in a first direction. During production the feeder worm (2) is periodically reversed and/or the speed of rotation of the feeder worm (2) is reduced in case the volume between the feeder worm (2) and the processing worm (3) tends to get blocked with the mass.

A method to grind meat in a grinder, includes: providing the meat to the grinder via a hopper where the hopper includes a feeder worm for feeding the meat to a process unit. The process unit has a rotating processing worm and a cutting set. The rotating processing worm can receive the meat from the feeder worm and convey it to the cutting set, which grinds the meat. The method involves automatically adjusting the revolutions per minute of the rotating processing worm in response to a pressure creation in the process unit.

A meat grinder includes a motor including a stator and a rotor including a motor shaft, a transfer case operatively coupled to the motor shaft, and a grinder head operatively coupled to the transfer case. The grinder head includes an inlet into which a raw meat product can be fed and an outlet through which ground meat can be discharged. Rotation of the motor shaft imparts operation of the grinder head via the transfer case. The motor also includes a housing comprising a generally cylindrical outer wall that is spaced from the stator thereby creating a cooling channel between the stator and the outer wall. The housing further includes a front wall including a plurality of inlet openings and a rear wall including a plurality of outlet openings. The motor also includes a heat sink inside the housing positioned in the cooling channel adjacent the motor stator. The motor further includes a cooling fan coupled to the motor shaft and positioned adjacent the rear wall. During operation of the meat grinder, the motor rotates the cooling fan which discharges air from the housing through the outlet openings, which draws air into the housing through the inlet openings, creating air flow through the cooling channel, the air flow through the channel drawing heat from the heat sink prior to being discharged through the outlet openings.

A device for comminuting media materials that store sensitive information. The device is a rotating mill core with removable flat edged blades, a set of stacked bed knives and a screen. The mill core rotates in close proximity to adjustable bed knives to shear the material being fed before passing through a screen in order to grate the material. The mill core has an angular positioned blade constructed and arranged to shear material with said bed knives. The mill core has a mass and is operated at 1000 rpm. A flywheel is further attached to the mill core in order to conserve rotational energy and improve the efficiency of the device. Vacuum ports facilitate cleanup.

A shredder device including a feed hopper, a screw conveyor and a shredder module, wherein the screw conveyor includes a screw conveyor shaft driven by a screw conveyor motor unit and having a screw conveyor flight formed thereon, and the shredder module includes a cutting drum having cutting openings formed therein, and a main screw rotatably arranged in the shredder module and having a main screw shaft, which is driven by a main screw motor unit, and a main screw flight which is formed thereon and passes over the cutting openings. The shredder device enables a higher cutting capacity. The main screw shaft is coaxially enclosed by the screw conveyor shaft inside the feed hopper up to the shredder module.

A rotor rotation device the rotor of a crusher includes a drive mechanism comprising a worm shaft and corresponding worm wheel. The worm wheel can selectively be coupled to said rotor in order to effect controlled rotation of the rotor, e.g. to facilitate maintenance of the crusher. The worm shaft cannot be back-driven by the rotor which allows the drive mechanism to serve as a lock against unwanted or uncontrolled rotation of the rotor.
