Alpine CW Contraplex Pin Mill – Hosokawa Micron Powder …
Available Options. The Alpine CW Contraplex Wide Chamber Impact Milis a fine impact mill with two driven pin discs. In counter-rotating mode, much higher relative speeds are possible than with the UPZ fine impact mill with only one driven pin disc. The highest relative speed develops at the outermost pin rows and can be up to 250 m/s.
Benefits of Cryogenic Grinding
Preserves product quality: A primary advantage of using cryogenic grinding is it reduces the product size to the required measures without affecting the quality. This is important across various industries, especially food and aquatic products. The process prevents thermal degradation throughout, thereby retaining the needed standard.
