The CryoMill is a cryogenic grinder designed with user safety in mind. The liquid nitrogen flows through the closed system and the user never comes into direct contact with LN 2 which ensures a high degree of operational safety. The automatic cooling system guarantees that the grinding process is not started before the sample is thoroughly cooled.
The plastics industry continues to explore cryogenic grinding as the demand for size reduction increases to particles sizes of less than 45 µm (325 mesh). These systems achieve uniform particle distribution and ultra-fine particle sizes, whilst simultaneously minimising overall operational costs and maximising production rates.
