Bond Tests

Bond Rod Mill Grindability Test The test determines the Bond Rod Mill Work Index which is used with Bond's Third Theory of Comminution to calculate net power requirements when sizing ball mills* Various correction factors may have to be applied The test is a closed-circuit dry grindability test performed in a standard rod mill

Milling (machining)

Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a work piece This may be done varying direction on one or several axes cutter head speed and pressure Milling covers a wide variety of different operations and machines on scales from small individual parts to large heavy-duty gang milling operations

Feed Rate Calculator

Feed Rate Calculator When milling or drilling or creating a tool path for a CNC machine the feed rate must be determined Materials have rated surface speeds for a given type of cutter The harder the material the slower the speed Given the diameter of the tool and the surface speed the RPMs of the spindle can be calculated Then if the tooth load for the cutter is know and the number of

Ball Mills

The ball mill is a tumbling mill that uses steel balls as the grinding media The length of the cylindrical shell is usually 1–1 5 times the shell diameter (Figure 8 11) The feed can be dry with less than 3% moisture to minimize ball coating or slurry containing 20–40% water by weight
