May , who guidelines define a particle finer than microns as mist, and finer than microns as fog the longray basic is a genuine fogger, producing a micron fog that diffuses faster, penetrates better, and has a higher probability of coming into
Laser fabrication of variable shape and small size holes lt microns, with controlled or zero taper, on a large variety of materials ipgs micromachining laser systems utilize a proprietary beam delivery technique for highspeed drilling that produces micro holes in less than second in thicknesses below m, and less than seconds
Hand mills are usually quieter than electric mills speed and efficiency mills can grind up to or more cups per minute, the greater, the faster is it with great speed and power comes great heat yes, mills tend to get very hot while running and the flour that comes out may heat up consequently this destroys the healthy nutrients in the flour

When the mill is rotated without feed or with very fine feed, the rods are in parallel alignment and in contact with one another for their full length new feed entering at one end of the mill causes the rod charge to spread at that end this produces a series of wedge shaped slots tapering toward the discharge end the tumbling and rolling rods expend most of their crushing force on the
