Bill Henry, executive VP at Jet Pulverizer (Moorstown, NJ), notes that ball and jet mills have traditionally been used to reduce particle sizes down to just below 1 micron, normally the upper-size domain limit for all things “nanotech.” “That’s the focus for these mills, particularly for electronics and battery applications,” says Mr. Henry. In pharmaceuticals, he adds, milling may be thought of as a “pregrind,” or precursor …

(Milling, grinding and size reduction) The fracture of a particle involves the propagation of cracks that are either already present or initiated in the particle. The stres required for fracture is given by the Griffith relationship: Where E is Young’s modulus, is the fracture energy, and L …

01/10/2020· This observation was attributed to the existence of a limit size in fracturing particles. For example, for dry silica sand milling a limit size of 1 μm was observed by Mucsi [ 7 ]. Cho et al. [ 10] found a limit size of 30 nm for silica sand in a stirred-media grinder where the particles were in …

When milling heat sensitive products, it can be difficult to stay within the strict temperature parameters, especially for heat-sensitive materials, when you have high output ambitions. To increase output with efficient milling practices, your need to ensure you find the optimum balance between milling size reduction and heat generation. An increase in temperature can lead to product degradation, reduced …
