A cap on a pepper grinder serves several purposes. It keeps pepper dry and fresh, adds to the overall aesthetic, and limits pepper mess, both on your counter and wherever else you may take it — parties, picnics, other gatherings. Built-in LED lights on a pepper grinder help light up the dish so you don't use too much pepper.

A variant of this method is to direct pebble-crushing circuit product to the ball-mill sump for secondary milling: while convenient, this has the disadvantage of not controlling the top size of feed to the ball-mill circuit. There have also been pioneer installations that have installed HPGRs as a second stage of pebble crushing.

Traditionally, ethanol from corn has primarily been produced through dry- and wet-milling processes. The majority of U.S. ethanol production is from dry-grind technology. The traditional dry-grind process grinds the whole corn kernel and mixes it with water and enzymes. The mash is then cooked to liquefy the starch further.

There has been a well established "truth" that wet grinding is more efficient than dry grind- ing. This should apply to ball mill grinding as well as autogenous grinding. It has been earlier shown that the effect of dry ball mill grinding increases considerably, when the fines are efficiently removed from the mill.

WET VERSUS DRY MILLING. The type of material being milled determines whether a mill should be dry or wet. Certain ceramic materials such as lithium disilicate and feldspathic porcelains require wet milling, as do some metals like chrome cobalt. Other materials, such as zirconia and titanium, can be milled dry or wet.
