Precision Knife Mill Type PS

 

Cutting of all types of plastic waste such as purgings, pipes, profiles, plastic bottles , film, fibers, carpet, etc.

Method of Operation

Precision Knife Mills allow the processing of film in form of rolls, edgings and loose material, cellulose, linters, textiles as well as natural and synthetic fibers, into fine powders with smooth particle surface and high bulk density.

Furthermore, Precision Knife Mills are also used for the recycling of valuable materials such as metal chips and foams.

Installation of the granulator is on the production floor or in a pit. Feeding is done pneumatically, with a metering screw, or feed rollers may be used for feeding material in rolls.

Material is size reduced between rotor- and bed knives. A screen holds material inside the grinding chamber, as long as it is too coarse. Fine material gets discharged through the screen into a pneumatic discharge system.

An open, slant cut rotor is standard. Bearings are outboard and no grease can enter the grinding chamber. Rotor and bed knives are adjusted outside the machine in a knife setting jig. Knife gap setting inside the machine is no longer necessary. A constant cutting circle is ensured. The screen is almost 180° and has a large open screen area. The standard hole size of the screen is 0,1 mm. Other screen sizes are available.
