Neue Herbold LM series granulators are specially designed for the size reduction of voluminous, thin walled materials. Typical applications are
- the size reduction of loose film ( in-line edge trims)
- the size reduction of hollow containers
- the size reduction of barrels
- the size reduction of crates
- the size reduction of PVC pipe (thin-walled PE/PP pipe)
- the size reduction of profiles (window profiles etc.)
- the size reduction of automotive bumpers
- the size reduction of web scrap
- the size reduction of injection moulding waste
- the size reduction of thermoforming scrap etc.
LM series granulators are designed with rotor and stator knives that are counter angled to each other producing a true scissors type cutting action. This design results in a cleaner more uniform granulate and reduced heat build up in the granulate. Double angle cut also reduces noise emissions and energy consumption. All knives are straight sharpening and require no special knife sharpening fixture. All cutting knives are pre-adjusted to the proper size gap outside the granulator with the use of the knife setting fixture which creates a constant gap between rotor blade circumference and screen resulting in reduced friction and therefore less thermal stress of the material.
Knife changes can be accomplished 60% quicker and safer then adjusting knives within the granulator. The bearings of the rotor shaft are mounted within solid steel housings (not castings) which offer more reliable service and eliminate any chance for the housings to crack or break under heavy shock loads. As opposed to flanged mounted bearings, outboard mounting prevents dust/fines from fouling the bearing nor grease from contaminating the granulate. Outboard mounting provides for a quieter and cooler operation. Improved rotor designs eliminate any chance for the rotor knives to lift or loosen during heavy shock loads.
The knife bolts attach to a removable and replaceable threaded clamp. The rotor flights nor the knife carrier are threaded preventing unnecessary drilling and tapping to repair stripped threads. The completely welded housing is designed with “clam shell“ opening characteristics for ease in maintenance.
