A high-energy mill was designed and built with the purpose of processing magnesium (Mg) powders. The main characteristics of the mill are grinding capacity of 1 kg and demolition elements of 10 kg; it Synopsis. A number of modern techniques suitable for the design of crushing and grinding circuits are described. The methods are based on extensive use of mathematical models of crushers, mills and classifiers and are seen as alternatives to conventional comminution design methods based on Work Indexcalculations.Practical modern techniques for the design of comminution

(PDF) Optimum Design of Hammer Mill for Grinding Leonardite

The conditions for the design and construction of the grinder are hammer thickness, 3, 6, and 9 mm, a number, hammer 20, 24, and 28. The size of the ground leonardite should range between 250 mmIn some cases, the rod mill can replace the short-head cone crusher for fine crushing. When the two-stage grinding process is adopted, if the first stage needs to be ground from 6–20 mm to 1–3 mm, the rod mill is used as the grinding equipment of the first stage, thus it has a larger production capacity and higher efficiency.Rod Mill SpringerLink

Occasionally, secondary crushing is included in the original design but is often added as an additional 4/7 circuit to account for harder oreThe rod mill operates at low-speed relative to the ball mill since the rods are rolled and not cascaded. However, one main disadvantage of the rod mill is that it needs significant operation attention because the rods must be parallel to one another to obtain a high crushing efficiency, otherwise the grinding action will be lost.Finite Element and Multibody Dynamics Analysis of a Ball Mill
