The Z-Series sanitary colloid mills are offered in a variety of models to produce ultra-fine particle size reduction and sub-micron dispersions and emulsions of varying viscosities. Featuring a milling head that requires no special assembly tools and can be CIPed, their rotor/stator gap adjustment is isolated from the process area and is fully adjustable during operation. Suitable for laboratory, pilot plant, and production use, the mills feature 316 stainless steel construction with Viton O-rings and comply with 3A, USDA, and FDA standards. Models are available with flow rates from 12 to 4,500 GPH and typical rotor/stator combinations are offered for products ranging from low-viscosity to abrasive slurries.
