An example of PVC profile granulation to relate the input material to the cutting system.
Technical video: observing an SM granulator in operation
Video of NEUE HERBOLD and keys to observe feeding, cutting and output of the material in a granulator mill.
Industrial knife geometry: cutting edges, holes and seating surfaces
A guide to document the functional zones of a blade and order a custom replacement.
Shredder, granulator and shear: choosing the cutting stage
The three machines reduce material, but fulfill different functions within an industrial line.
Hardfacing knife holders: assess the part before repair
What to check on a worn blade holder before deciding between hardfacing, machining or replacement.
HRC hardness and toughness: interpreting an industrial knife specification
Hardness is a useful piece of information, but it must be evaluated together with the steel, the type of wear and the cutting conditions.
Heat treatment of industrial knives: checks for each batch
Hardening, tempering and dimensional control: what information should be reviewed when purchasing or manufacturing industrial blades.
Industrial blade wear: distinguishing abrasion, chipping and plastic deformation
Industrial blade wear does not always call for higher hardness. Learn to distinguish abrasion, edge chipping and plastic deformation before selecting a replacement.
WEIMA: adapt rotor and blades to plastic waste
Selecting blades for a plastic shredder should begin with the waste and the installed rotor. Film, fibers and rigid pieces arrive at the cutting area in different ways, even when they belong to the same polymer.
