Bruxism is often classified as either nocturnal ('grinding teeth in sleep') or day-time. Day-time bruxism often occurs while the person is under stress and/or concentrating on some task (e.g. driving, working) and usually involves jaw clenching more so than grinding.

I realize the actual time is relative to exactly how you grind and what you are doing, but I'm more interested in the relative grind. How big is the difference between 400 to 500, compared to how long it would take to go from 500 to 600 and 600 to 700?
CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.

Dec 16, 2014· If your teeth are sharp, and the stump is cut low, you may probably need 5-10 minutes to grind a 15" 4" deep with a 20hp. If you hit a hard, big rock on the 2nd stump you may have your teeth screwed already and the other stumps take twice as long. And there is a learning curve in grinding.
The depth in the center of the mirror is the mirror's sagitta. The sagitta determines the mirror's focal length and focal ratio. There is plenty of time to contemplate the desired focal length while rough grinding! Here's a table of depths across a variety of mirror diameters and mirror focal ratios:

All Grinding Mill & Ball Mill Manufacturers understand the object of the grinding process is a mechanical reduction in size of crushable material. Grinding can be undertaken in many ways. The most common way for high capacity industrial purposes is to use a tumbling charge of grinding media in a rotating cylinder or drum.
In Grinding, selecting (calculate) the correct or optimum ball size that allows for the best and optimum/ideal or target grind size to be achieved by your ball mill is an important thing for a Mineral Processing Engineer AKA Metallurgist to do. Often, the ball used in ball mills is oversize "just in case". Well, this safety factor can cost you much in recovery and/or mill liner wear and tear.
