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.

A horizontally fed disk grinding system includes a tray coupled to a trailer for receiving bulk material. The system further includes a grind hub coupled to the trailer and a cutter disk coupled to the grind hub. The grind hub is structured to rotate about a grind hub axis and the cutter disk is structured to rotate about a cutter disk axis and about the grind hub axis. A grind ring is coupled to the trailer and is structured to slide to engage the grind hub during use. A plurality of plates are coupled to the tray and structured to oscillate to feed material from the tray to the grind hub and the cutter disk, where the material is reduced to particulate form. The grind hub further includes an outlet and a conveyor rotatably coupled to the trailer to convey the particulate material away from the outlet to a selected location.

A paper shredder includes a chassis on which an automatic paper feeding opening is defined, a paper shredding mechanism, a paper separating mechanism located adjacent to the automatic paper feeding opening, and a paper pickup mechanism located between the paper separating mechanism and paper shredding mechanism. The paper separating mechanism includes a first paper supporting board on which a fastening mechanism is provided and a paper separating board cooperating with the fastening mechanism. The paper pickup mechanism includes a holding bracket, a paper pickup roller axe, a plurality of paper pickup rollers sleeved on the axe, a second paper supporting board located below the plurality of rollers and secured onto the second paper supporting board, and a third paper supporting board located above a distal end of the second paper supporting board and connected with the paper separating mechanism.

A method for disposing of propellant containers containing a propellant, comprising submerging the propellant containers in a detonation suppressant liquid, shredding the propellant containers while submerged in the detonation suppressant liquid into shredded propellant container material reduced in size to provide release of the propellant from the propellant containers, and removing the shredded propellant container material from the detonation suppressant liquid. A system for disposing of propellant containers is also disclosed.

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.

An implant shredder includes a base and a cutting member. The base includes a first chamber and a second chamber intercommunicating with the first chamber. The first chamber includes an inlet. The second chamber includes an outlet. The cutting member is received in the second chamber. The cutting member is driven by a driving member to rotate. The cutting member includes a plurality of cutting edges located on a circumference of a same radius. The plurality of cutting edges is rotatably disposed adjacent to a location intercommunicating with the first chamber. An implant forming method includes creating data of an outline of an implant; producing a shaping mold based on the data; and cutting a to-be-processed object with the implant shredder, then mixing the to-be-proceed object with a biological tissue glue to obtain a raw material, and filling the raw material into the shaping mold to form the implant.

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 shredding arrangement for shredding material to be shredded, such as household waste, industrial waste, plastics, wood, paper and/or biomass, comprising a shredding device, which is arranged on a machine frame, and a supply device having at least one infeed roller drivable to rotate using an associated drive device for supplying the material to be shredded to the shredding device. The shredding arrangement is distinguished in that the infeed roller is configured to accommodate the associated drive device, and the drive device has an electric motor, gearing, and a flexible coupling.

A shredding assembly for tearing a plastic article, such as waste bottles into pieces or pellets. The shredding assembly includes rails that can be installed at a height and a shredder. The shredder includes a housing mounted on the rails and can slide from a stowed position to over one or more trash bins. The shredder includes two rollers mounted within the housing and a drive mechanism for counter-rotating the two rollers.
