We can supply knives for any machine, from a small slow speed to the multipurpose heavy duty granulator.

Our experts have a wide experience of optimising granulator knives design according to each particular application.  To manufacture our blades we use only top quality, accredited European steels.

We manufacture Granulator Bed and Rotor Knives at our ISO9001 certified factory in Sheffield

When we manufacture all our blades and knives we use only the highest quality steel. Moreover, we have internationally recognised standard of quality assurance  at our ISO9001 certified factory.  We manufacture off-shelf and customised Zerma granulator bed knives and rotor knives according to OEM specifications.

We grind our knives per set to ensure a precise gap fit, precision cutting, longevity and machine balance. Also we offer a tough-tipped blade for superior lifespan and performance, which can deliver significant savings by reducing plant downtime and the risk of damage.

Therefore, ensure that all our customers constantly generate uniform regrind with minimal dust content. We supply Zerma Granulator knives to customers all around the world, and by now we have build a large database of drawings.
