How To Calculate Grinding Media Sizes For Ball Mill

AMIT 135: Lesson 7 Ball Mills Circuits – Mining Mill ...
Ball Mill Size as a Replacement. Grinding media wears and reduces in size at a rate dependent on the surface hardness, density and composition of the ore. Ball wear is directly proportional to surface area per unit mass and thus inversely proportional to ball diameter. Other factors include: Speed of mill rotation; Mill diameter; Mineral density; Work Index. Bond estimated the amount of wear ...

Ball Milling The Role of Media and Bead Mills
Basket bead milling is a relatively new design for ball milling appliions. The grinding media is contained in a cylinder (basket), and the mill base is circulated through the basket. The VMAGetzmann basket mill consists of a stainlesssteel cylinder with an opening at the top and a sieve filter on the bottom. The standard diameter size of the grinding media is mm. however, it can be ...
