Design guide for CNC Milling - EngineeringClicks

Maintaining a tight tolerance between features produced in a single setup is far easier than keeping the same tolerance between ple setups. Where function isn't affected, try to design your part so tight-tolerance features are created in a single setup. On a related note, it's a good idea to limit the number of tools that will be required to make your part. For example, many holes of ...

AMIT 135: Lesson 7 Ball Mills & Circuits – Mining .

Ball Mill Design. A survey of Australian processing plants revealed a maximum ball mill diameter of 5.24 meters and length of 8.84 meters (Morrell, 1996). Autogenous mills range up to 12 meters in diameter. The length-to-diameter ratios in the previous table are for normal applications. For primary grinding, the ratio could vary between 1:1and 1.8:1. For fine regrinding in open circuit, the ...
