The colloidal mill works with semi-liquid\/pasty and never dry products (no powders), with a initial grain size up to several mm, to obtain a minimum final grain size at the output approximately in a range between 50um and 100um, depending on the product treated. Colloidal mills are available in different standard sizes with flow rates between 500 and 80,000 l\/h at depending on the configuration of the machinery and the viscosity of the product.
