A new 29.5-in.-diam CGM 750 cone mill gently grinds fatty, heat-sensitive, sticky, moist, or fragile materials into uniform particle sizes with minimal fines, at rates to 35 tn/hr.

Vertical material flow and low-energy grinding action with short residence times yield close particle size distribution from 125 to 250 microns, without the noise, dust, product build-up, or heat generation associated with traditional mills. 

Ideal for bulk pharmaceuticals, foods, and contamination-sensitive chemicals, the sanitary unit is suitable for wet and dry milling, pre-conditioning and de-agglomerating of a wide range of bulk products.

Material is fed by gravity or vacuum conveying system into a central milling chamber in which a rotating impeller accelerates it centrifugally against and through apertures in a conical screen, and then into a receptacle below the milling chamber. 

A pneumatic, swing-down conical discharge chute with quick-release clamps allows easy  lowering of the 250-lb cone housing and full access to the housing interior, beater, and perforated conical screen for cleaning and sanitizing. The unit can be cleaned wet or dry, and is available configured for CIP, SIP, or filling with liquid during cleaning.  Provision is included for optional air purging of bearings and seals.

Conical screens with round, square, or raised-lip (cheese grater) perforations can be changed rapidly and are offered with apertures from 150 micron for fine/dry de-agglomeration, up to 25 mm for wet granulation. 

Constructed of 304 or 316 stainless steel to sanitary or industrial standards, the mill is top-driven by a belt drive and equipped with fully interlocked moving components with time-delay function for operator safety. Explosion-containment versions are also available. 

Smaller models range in diameter from 3 in. for laboratory applications to 27 in. for production capacities.
