OTHER PRODUCT GROUPS P-14 Rotary Mill
The FRITSCH P-14 rotor mill combines impact, cutting, and shearing size reduction in a single instrument—offering higher throughput, superior cooling, and significantly lower noise levels compared to similar devices. Its powerful motor is ideally suited for the rapid processing of soft to medium-hard, brittle, and fibrous materials, as well as heat-sensitive samples. The exceptionally high throughput can be further increased through the use of FRITSCH cyclone separators.
Given its high performance, the P-14 is the ideal rotor mill for pilot-scale processing within the plastics industry.
Essentially two mills in one: by using a cutting rotor, the P-14 transforms into a cutting mill, enabling fast and efficient pre-grinding and fine-grinding of soft to hard fibrous materials and plastics.
