In determining the proper mill size required to meet a targeted production rate, many factors are evaluated including: length to diameter (L/D) ratio, individual compartment lengths, rotational velocity, liner type, ball gradation and percent filling degree.
the mill dimensions (length, diameter, L/D ratio), and finally the mill operating conditions (fraction of the mill filling f L, mill critical speed f C, mill grinding load).

The supporting roller bearings features smaller width over diameter ratio L/D, leading to its higher reliability. ... The special highstarted torque motor for cement industry rotary kiln is applied for driving system. ... Rotary kiln with two supports is a kiln of L/D<, with .
Both farms, however, can only offer the monopsony price and yield the resulting land demand if l ≥ 2 D i UR (v), which refers to high importance of space σ ≥ 2 (p − v + s) and locally separated markets. 26. For lower values of σ, both farms compete for land and the farm with the higher UR price will capture all or most of the land supply.
Aug 13, 2016· If the ratio of acute toxicity of fish analysed through static and flowthrough methods is, Ratio < – the pesticide is more toxic under static than under flowthrough conditions. Ratio to – no much difference in toxicity in the two bioassay methods. .
The aspect ratio (l/d) is calculated by dividing fiber length (l) by its diameter (d). Fibers with a noncircular cross section use an equivalent diameter for the calculation of aspect ratio. If the fiber's modulus of elasticity is higher than the matrix (concrete or mortar binder), they help to carry the load by increasing the tensile strength ...
Aspect ratio (l/d) is calculated by dividing fibre length (l) by its diameter (d). Fibres with a noncircular cross section use an equivalent diameter for the calculation of aspect ratio. If the modulus of elasticity of the fibre is higher than the matrix (concrete or mortar binder), they help to carry the load by increasing the tensile strength of the material.
The expression can be derived from the Lamé equation for tangential stress by making the thinwall assumption that D/t >> 1. Most casing used in the oilfield has a D / t ratio between 10 and 35. The factor of appearing in the equation represents the allowable manufacturing tolerance of –% on wall thickness specified in API Bull ...
