A milling system to comminute a material may generally include a hopper feeder system, a cutting mill, a collection system, each in fluid communication to provide a flow path, and a control system. The control system may include a controller operatively connected to at least one sensor to sense the amount of material, if any, along the flow path, and the speed, if any, of the material along the flow path. The control system, in response to signals received from the at least one sensor, may cause at least one of the hopper feeder, cutting mill, and collection system to increase the speed, decrease the speed, or stop the flow of material along at least a portion of the flow path. Methods of making and using the same are also described.

The disclosure extends to apparatuses, methods, and systems, for producing frozen confections and conditioning ice for use in frozen confections. The disclosure further extends to apparatuses, methods, and systems for providing a frozen confection machine that is portable and sized for easy storage as well as a portable frozen convection experience.

A machine for distributing material from a package of compressed loosefill insulation material is provided. The machine includes a lower unit having a front panel. A shredding chamber is bounded on one side by the front panel and the shredding chamber receives compressed loosefill insulation material from a source of compressed loosefill insulation material. The shredding chamber including a plurality of shredders for shredding, picking apart, and conditioning the loosefill insulation material. A discharge mechanism is mounted to receive the conditioned loosefill insulation material exiting the shredding chamber and to distribute the conditioned loosefill insulation material into an airstream. A removable front access assembly covers a portion of the front panel of the lower unit and includes a control panel having a plurality of control devices. Removal of the removable front access assembly makes the plurality of shredders and the discharge mechanism within the lower unit accessible for inspection, replacement, or repair.

A chipper includes a hopper and a chipper unit. The hopper is configured to receive vegetative debris via an inlet end. The chipper unit has an outer casing and an inlet passing therethrough. The inlet of the chipper unit is connected to the outlet end of the hopper to in use receive the vegetative debris within the outer casing. The chipper unit includes a cutter located which is configured to chip vegetative debris. The hopper and the outer casing are configured so that the hopper and outer casing can be moved between a position where the hopper is substantially vertical and a position where the hopper is substantially horizontal.

The comminution device includes a feed opening for feeding material to be comminuted, a comminution shaft for comminuting the material fed to the device, and a cutting chamber, arranged between the feed opening and the comminution shaft and delimited by a cutting chamber wall, which can be pivoted.

A machine for distributing loosefill insulation material from a package of compressed loosefill insulation material. The machine includes a chute having an inlet end and an outlet end. The inlet end receives compressed loosefill insulation material. The chute has a first portion and a second portion. The first portion forms an angle with the second portion. A shredding chamber receives the compressed loosefill insulation material from the chute. The shredding chamber forms conditioned loosefill insulation material. A discharge mechanism is configured to distribute the conditioned loosefill insulation material into an airstream. A blower provides the airstream. The angle between the first and second portions of the chute is configured to form a bend in the package of compressed loosefill insulation material. The bend in the package of compressed loosefill insulation material is configured to control the descent and direction of the loosefill insulation material entering the shredding chamber.

A bone grinder is provided herein. The bone grinder may have a grinding chamber, an intermediate zone, and a primary cutting element and a secondary cutting element. The intermediate zone may have a first wall and a second wall within the grinding chamber, and the intermediate zone may separate the primary cutting element from the secondary cutting element. The first wall and the second wall may slope inward such that a distance between the first wall and the second wall generally decreases from the primary cutting element to the secondary cutting element. The primary cutting element and the secondary cutting element may be positioned within the grinding chamber to sequentially perform primary cutting operations and secondary cutting operations on a bone. A drive mechanism may operatively engage the primary cutting element and the secondary cutting element.

The method or process described is directed at conditioning and packaging freshly chopped biomass such that it can be stored for a long period of time without spoilage and such that the packaged chopped biomass is easily transportable and its composition and other properties remain stable.

A method for controlling a crusher having a crushing tool and a vibratory conveyor (1) having a drive (5), includes capturing bulk material (2) in a capture region (4) using a sensor (3). So that, in the case of grains with an inhomogeneous grain size distribution, even large grains can be crushed with a constant crushing result without a risk of the crusher being damaged, an effective diameter d.sub.eff, which results from the largest diameter d.sub.max and the direction (9) thereof, transverse to the conveying direction (8) of a grain of the bulk material (2) is determined as the controlled variable in the capture region (4). If the effective diameter d.sub.eff exceeds a predefined power threshold value, the power of the crushing tool is increased and/or, if the effective diameter d.sub.eff exceeds a predefined switch-off limit value, the drive (5) is switched off.

A machine for distributing material from a package of compressed loosefill insulation material is provided. The machine includes a chute having an inlet end and an outlet end. The inlet end is configured to receive compressed loosefill insulation material. A lower unit has a shredding chamber configured to receive the compressed loosefill insulation material from the outlet end of the chute. The shredding chamber includes a plurality of shredders configured to condition the loosefill insulation material. The shredders include a shredder shaft and a plurality of vane assemblies. The vane assemblies are oriented such that adjacent vane assemblies are offset from each other by an angle of about 45° to about 75°. A discharge mechanism receives the loosefill insulation material exiting the shredding chamber and distributes the loosefill insulation material into an airstream and a blower is configured to provide the airstream flowing through the discharge mechanism.
