what is the l d ratio in a ball mill

  • What should be the ideal proportion of ore to grinding ...

    achieving coarse grinding in a ball mill is the function of a number of parameters: 1, The mill L/D ratio must be low, for example diam. 9ft x 10ft long. 2, The mill must be of grate discharge configuration as opposed to overflow discharge. This will ensure a steep hydraulic gradient in the mill for rapid passage of the ore through the mill.

  • Dry milling and fractionation of grain - Wikipedia

    Dry milling of grain is mainly utilized to manufacture feedstock into consumer and industrial based products. This process is widely associated with the development of new bio-based associated by-products. The milling process separates the grain into four distinct physical components: the germ, flour, fine grits, and coarse grits.The separated materials are then reduced into food products ...

  • Consider L:D When Choosing A Lathe For Small Parts ...

     · Should shops always defer to Swiss-type lathes to process small, long and often complex parts? Not necessarily. As a general rule, a Swiss-type is most appropriate for machining workpieces with L:D ratios of 4 to 1 or greater. Parts with lower L:D ratios may be machined economically on turn-mills.

     · Two-stage screws benefit more with increasing L/D because about 6 D is consumed in the vent area, which contributes very little to melting or pressurization. For most applications, you’ll need a 30:1 two-stage screw to match the output of a 24:1 single-stage screw (see accompanying illustration).
