Abstract: A sifter insert for use in a sifting device has an insert frame and a screening media affixed thereto. An insert frame air channel is located within the insert frame. The sifter insert is sized to be received in a sifter box frame of an associated sifter box. The sifter box frame has a box frame air channel in fluid communication with the insert box frame channel of the received sifter insert. The passage of air through the box frame air channel and the insert frame air channel may cool the sifter box and the insert frame, and may cool the screening media and the material being sifted thereon. Channel holes in the insert frame may direct air from the insert frame air channel to the screening surface of the screening media.

Abstract: A reducing machine having an air cooled cutting discs is disclosed. The air cooled discs have cutting surfaces on both sides. The cutting surfaces have edges which are sharpened for cutting input material when the cutting surface is facing the cutting surface of the opposed disc. When the cutting surface of the stationary disc is facing the housing, the cutting surface acts as a heat sink to air cool the stationary disc and the mill assembly in general. Air inlets in the housing lid permit air to flow over the cooling surface of the stationary plate. Air inlets in the carrying plate permit the carrying plate to channel air flow over the rotating cooling surface. A damper restricts air flow over the air cooling surfaces to control the temperature of the reducing machine, such as during start up.

Abstract: A disc mill assembly of a reducing machine has a housing for housing a first stationary cutting disc in operative interaction with a second rotating cutting disc and separated therefrom by a relative gap distance. The stationary disc is fixed to a housing lid of the housing and the rotating disc is rotatably fixed to a housing body. The relative gap distance between the cutting discs is adjustable by adjusting mechanisms adjusting a relative housing distance between the housing lid and the housing body. A particle size detection analyzer detects the size of particles emanating from the disc mill assembly to generate a detection signal which may be used by the controller to obtain a desired particle size distribution.
