Contact Us##### Tribological Processes in a Ball Mill for Ordinary

There are two types of milling processes when using the ball tube mill viz. the open and closed milling processes. A mill is said to be closed circuit if there is no entrance for air i.e. air does not flow in and out of the maximum shear stress closer to the surface (Arnell R.D, et al., 1991). As this process continues, it is observed

I assume you are referring to a ball mill, since cyclone discharge recycle normally goes back to ball mill feed. I am less versed in ball mill grinding. Ball mills break rock by compression fracture, while SAG mills predominantly break by shear. Some compression fracture does occur, but, it is not the major comminution mechanism.

Contact Us##### Chocolate mass processing technologies an overview

As chocolate mass is a non Newtonian fluid we have to measure its shear stress at different shear rates, which results in a flow curve. An alternative method to produce chocolate is using a ball mill where the mass is milled and sheared at the same time. Although cocoa liquor is usually ground by ball mills, those are not popular for
