Kason Kek-Gardner, Macclesfield, UK, has launched the Model CM540 sanitary cone mill which has been designed to deliver gentle, low-energy size reduction while achieving even particle distribution with minimal fines.  It is suitable for delumping of dried or hygroscopic materials that have agglomerated owing to dampness or compaction, for intermediate sizing of ‘wet mass’ product for improved drying and granulation prior to tableting, and for regrinding of out-of-spec tablets to be reintroduced to the tableting process. 

 

Its smooth, moderate action alleviates traditional milling problems of product build-up, dust and heat generation, enabling it to process fatty, heat-sensitive, sticky, moist or fragile products. Intended for pharmaceutical, food and chemical applications in which contamination must be avoided, the mill provides consistent results within fine limits.

 

Material is fed by gravity or pneumatically into a central milling chamber in which a rotating impeller accelerates it centrifugally against and through apertures in a conical screen, and from there into a receptacle below the milling chamber.  Conical screens can be changed rapidly, and are offered with apertures from 150 microns for fine/dry de-agglomeration, up to 25mm including square and rectangular perforations for wet granulation. Constructed of #304 or #316 stainless steel to sanitary standards, the mill can be wet or dry cleaned. www.kasonkekgardner.com.
