How can one select ball size in ball milling and how

Ball size depends on initial size of charge and ranges from 10mm-150mm dia. For particular material and initial size the ball size must be optimized. Please refer the link below and see if it

Effect of ball and feed particle size distribution on the

2018-6-1  For this coarser feed the 50 + 20+10 mm ball diameter mix breaks the material at a faster rate compared to the other ball matches. The availability of a ball size for a particular feed size ensures breakage occurs at a faster rate. The 10 mm ball size is unable to nip the large particle size hence the breakage rate is slower.

Feed Size VS Ball Size Grinding & Classification

For ball mill, Bond (1958) was proposing an empirical formula giving the top size of balls (make-up balls) DM function of the feed size xG (80% passing size µm), the ore true specific gravity sg, the ore Bond Work Index Wi (kWh/st), the fraction of critical speed fc and the inside mill diameter D (m):

Ball Size as Initial Charge. Commercial ball sizes 10 150 mm; Number, size and mass of each ball size depends on mill load and whether or not the media is being added as the initial charge. For the initial chargin of a mill, Coghill and DeVaney (1937) defined the ball size as a function of the top size of the feed, i.e., d↓V = 0.40

fraction of feed size R, and S1 as grinding rate con­ stant K1 in Eq. (3). Silica glass was ground with a ball mill while varying the feed size and ball diameter, and measured K1. (3) An experimental equation was obtained by expressing K1 as a function of feed size and ball diameter. 2. Sample Used and Experimental Method

Speeds And Feeds For Milling With End Mills

Use the SFM and the diameter of the mill to calculate the RPM of your machine. Use the RPM, IPT, CLF and the number of flutes to calculate the feed rate or IPM. If you want to be conservative, choose a slightly lower SFM, but always choose the recommended FPT.

Scats production in overflow ball mill Grinding

2021-5-4  Too small a grinding ball (what size is your?) Sometimes, you solve scatting by charging the ball mill correctly (I saw cases where the mill was up to 15% under power). Other times, you need to enlarge the ball size diameter ie: using a 75 mm ball instead is 35 mm. Other times, you must control and reduce the feed size (crushing circuit product).
