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.

An apparatus for recycling synthetic thermoplastic waste material combining heretofore multiple stage processing steps in a single stage shredder grinder pulverizer device. The apparatus has multiple interchangeable material processing blade sets on respective effacing engageable rotating and fixed blade mounts within a cooled material infeed and blade containment enclosure with multiple vacuum outlet ports and communicating vacuum ducts to draw off and transport processed material therefrom for separation and classification, as required. Each replaceable interchangeable processing blade set includes registerable shredding and grinding blades and annular pulverizing blade sets on fixed and movable mediums for progressive processing of waste material into uniform recyclable material.

A mill includes a first mill having a first grinding region, a second mill having a second grinding region opposed to the first grinding region and provided to be rotatable relatively to the first mill, and a heat radiation mechanism which is provided in at least one of the first mill and the second mill and radiates friction heat generated as a result of rotation of the first mill and the second mill relative to each other, and the heat radiation mechanism is provided in a portion except for the first grinding region and the second grinding region.

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.
