Gear cutting

To machine a helical gear on a manual machine a true indexing fixture must be used Indexing fixtures can disengage the drive worm and be attached via an external gear train to the machine table's handle (like a power feed) It then operates similarly to a carriage on a lathe As the table moves on the X axis the fixture will rotate in a fixed ratio with the table The indexing fixture

How to Size a Ball Mill

 A) Total Apparent Volumetric Charge Filling – including balls and excess slurry on top of the ball charge plus the interstitial voids in between the balls – expressed as a percentage of the net internal mill volume (inside liners) B) Overflow Discharge Mills operating at low ball fillings – slurry may accumulate on top of the ball charge causing the Total Charge Filling Level to

Machining Speeds and Feeds Equations Calculator

Machining Speeds and Feeds Equations Calculator Machining operations may be conducted on machine tools having a rotating spindle or a rotating part (lathe) Cutting speeds are usually given in feet or meters per minute and these speeds must be converted to spindle speeds in revolutions per minute to operate the machine

Common Basic Formulas for Mineral Processing

Pulp Densities Pulp densities indicate by means of a tabulation the percentages of solids (or liquid-to-solid ratio) in a sample of pulp This figure is valuable in two ways—directly because for each unit process and operation in milling the optimum pulp density must be established and maintained and indirectly because certain important tonnage calculations are based on pulp density

Circular mil

A circular mil is a unit of area equal to the area of a circle with a diameter of one mil (one thouh of an inch or 0 0254 mm) It corresponds to approximately 5 067 10 −4 mm 2 It is a unit intended for referring to the area of a wire with a circular cross section As the definition of the unit contains π it is easy to calculate area values in circular mils knowing the diameter in
