How to design a Ball Mill Grinding & Classification

You also need a rod mill work index to design a ball mill operating on a coarse feed, above about 4 mm. Q1: You design for a typical percentage of critical speed, usually 75% of critical. Then you iterate the mill diameter using a Morrell C-model or Nordberg equation to get the RPM that corresponds to 75% for that mill diameter.

A guide to maximising ball mill circuit classification

Classification system efficiency (CSE) is a composite measurement of the net performance of the classification system in a ball milling circuit. Functional Performance, as developed by McIvor, defines Classification System Efficiency, as the net amount of coarse material in the ball mill (McIvor, 1988a). The ‘dividing line’ between ‘coarse’ and ‘fine’ will depend on the grind target of a given circuit, and it is

Ball Mill Circuit Classification System Efficiency

22/04/2018 Ball Mill Circuit Classification System Efficiency Fines may be defined as any material smaller than a specified product size, and “coarse” as any material that is larger. The target 80 percent passing size of the grinding circuit product is a convenient reference point, as it is often used to express the grind size objective.

A Review of Advanced Ball Mill Modelling

A Review of Advanced Ball Mill Modelling has allowed engineers design mills and improve a large number of operations throughout the 20th century (Herbst and Fuerstenau, 1980).

Ball Mill Application and Design Paul O. Abbe

Ball mills are simple in design, consisting of horizontal slow rotating vessels half filled with grinding media of ¼” to 1.5”. The particles to be milled are trapped between the grinding media or balls and are reduced in size by the actions of impact and attrition. Ball mills have the advantage of being self-contained so operators are not exposed to the product being milled. Ball mills
