    A study on the control of particle size distribution (PSD) of the ground carbonate product in stirred media mills (wet Drais stirred bead mill and dry Sala Agitated Mill) is presented in this paperStirred Media Detritor (SMD) is a fluidized, vertical stirred mill designed for optimum grinding efficiency for fine and ultrafine grinding products SMDs have the capacity to operate continuously at full load power draw with no steel contamination of the product They are suitable for both open and closedcircuit operationStirred mills for wet grinding minevik Outotecclosedtype stirred media mill the design principle of a mill with a disc stirrer is shown in Figure 2 The mill is equipped with a rotating gap for the separation of the grinding media Today, closed­ type stirred media mills are built with grinding chamber volumes of less than 1 litre (laboratory 92Review Wet Comminution In Stirred Media Mills

  • Wet comminution in stirred media mills — research and its

    The importance of stirred media mills in various industries and in research is steadily increasing The comminution process in these mills is determined mainly by the number of stress events in the grinding chamber and by the intensity acting at these stress events: for a certain stress intensity a certain relation between the product fineness and the number of stressselecting grinding media size, denisty of grinding media, and mill speed to approach an optimum stress intensity and maximize the stress number Due to Kwade´s investigations and modelling of grinding and dispersing with stirred media mills, the following milling tests with calcium carbonate and different grinding mediaThe effect of grinding media J performance on millingThe results showed that wet grinding in a stirred bead mill using the smaller grinding media (500 µm) is an effective method for reduction of product size (∼500 nm) of the CaCO3 powder ViewProduction of SubMicron Particles by Wet Comminution
