摘要： A particle blast apparatus includes a metering portion, a comminutor and a feeding portion. The metering portion and comminutor may each be configured to provide uniformity in the discharge of particles. The metering portion controls the particle feed rate, and may include a rotor, which may have V or chevron shaped pockets. The comminutor includes at least one roller which may be moved between and including a position at which the gap of the comminutor is at maximum and a position at which the gap is at minimum. The metering portion may discharge particles directly into the feeding portion without a comminutor being present. The comminutor may receive particles directly from a source of blast media without a metering portion being present.

摘要： A tool for feeding material into a mill having a roller and forming a nip gap. The tool broadly comprises a baseplate, a guide plate, and a ram. The baseplate is configured to be positioned on the mill over the roller and forms a slot. The guide plate is configured to be positioned in the slot of the baseplate near the nip gap. The guide plate forms a chute for feeding the material into the nip gap. The ram is configured to be inserted into the chute to urge the material into the nip gap while preventing a user's fingers and other foreign objects from nearing the nip gap through the chute.

摘要： A comminution device configured to comminute material is disclosed. According to some embodiments the comminution device may comprise a first cylindrical roll having a first axis; and a second cylindrical roll having a second axis; wherein the first axis may be substantially parallel with the second axis to form a nip between the first cylindrical roll and the second cylindrical roll during operation of the comminution device. A first drive 50 may be operatively connectable to the first cylindrical roll, and a second drive 50 may be operatively connectable to the first cylindrical roll. The first drive 50 and the second drive 50 may be connected to a mount 10; wherein the mount 10 may be supported by an upper base 30. The mount 10 is movable along a direction (A-Axis), which is substantially parallel with the first and/or second axis. Also disclosed, is a drive assembly 1 for a comminution device and a method of removing a drive assembly 1 from a comminution device.

摘要： A method and apparatus for grinding fresh stock, comprising comminuting the fresh stock in a first roller press roller gap into ground grinding stock, dividing the ground grinding stock via an adjustable divider into a first and second part stream in a variably adjustable ratio and comminuting the ground grinding stock of the first part stream in a second roller press. The adjustable divider divides ground grinding stock into an intermediate stream comprising ground grinding stock issuing from an intermediate roller gap region, and into two peripheral streams each comprising ground grinding stock issuing from one of the two roller gap peripheral regions. The two peripheral streams are combined to form the first part stream and the intermediate stream forms the second part stream. The second part stream is conveyed from the divider into a bypass line, passing the second roller press.
