Drilling Performance Optimization Based on Mechanical Specific Energy
Mechanical specific energy (MSE) has been widely used to quantify drilling efficiency and maximize rate of penetration (ROP) in oil and gas wells drilling. In this chapter, MSE models respectively for directional or horizontal drilling and rotating drilling with positive displacement motor (PDM) are established based on the evaluation of …

Influence of ball milling parameters on the particle size of …
With increasing speed of the ball mill from 200 to 400 rpm at a fixed milling time of 30 h, the particle size of the milled powders decreases gradually till it reaches a saturation value. This observed result agrees with a mathematical model that describes the dependence of post-milling particle size on the rpm of a mill.

Ball Mill
According to the ratio of cylinder length (L) to diameter (D), the ball mill can be divided into short cylinder ball mill, L/D ≤ 1; long barrel ball mill, L/D ≥ 1–1.5 or even 2–3; and tube mill, L/D ≥ 3–5. According to the cylinder shape of the ball mill, it can be divided into cylindrical ball mill and cone ball mill.

The effect of ball size on mill performance
The specific rates of breakage of particles in a tumbling ball mill are described by the equation S i = ax α i (Q(z), where Q(z) is the probability function which ranges from 1 to 0 as particle size increases.This equation produces a maximum in S, and the particle size of the maximum is related to ball diameter by x m = k 1 d 2.The variation …
