Grinding to nano-sizes: Effect of media size and slurry viscosityFeb 17, 2015 . The growing trend towards ultrafine milling makes it worthwhile to study the effect of key variables on this process. The concept of the ''grinding zone'' is defined and analysed. It is found that (volume of grind- ing zone)/(volume of voids between media) is proportional to [(particle size)/(media size)]2.ultra fine grinding mills slurry,Stirred Media Detritors (SMD) - Stirred media detritor Premium ultra fine grinding technology. . The SMD utilizes the rotational energy of the impeller arms to impart a high-energy motion to the media/ slurry mixture inside the mill. This results in particle-to-particle shear and compressive forces which produce the desired grinding mechanism for fine.
