fine particles is the spiral jet mill or pan-cake mill. The particles fed to the grinding chamber are accelerated by the high gas flow (typically in the range of 4-8 bar g) and particles are crushed by collision with each other as well as partly at the walls of the grinding chamber. Due to the fact that there are no mova-

One of the known disadvantages of fine grinding is the increased incidence of gastric ulcers. The frequency of ulceration increases when particle size drops below 500 microns. Other disadvantages of fine grinding include bridging problems in bulk bins and feeders as well as increased dustiness of the feed. Particle size in practice

As an example, pin mills are used for fine grinding of lactose. Typical finenesses are around 300 μm and the typical maximum fineness with lactose is around 90% <75 μm. When steeper particle size distribution or higher-end fineness is required, an impact mill with an integrated air classifier might have advantages (Figure 3).

Swine Nutrtion Guide--Feed Processing - NCSU

At present, considering improvements in feed efficiency, processing costs, incidence of gastric ulcers, and potential for bridging, an average particle size of 700 to 800 microns is recommended. In addition, fine (700 microns) grinding of high-fiber feed ingredients has been shown to improve their feeding value.

Feeds sifted through a 177-micron opening (a U.S. No. 100 sieve) have been successfully used for increasing survival and growth of minnows and catfish fry. Hammermill or impact grinding of dry feeds, especially cereal grains, creates particles within the range called "dust", and a dust-collecting system may be necessary to remove this.

GRINDING FEEDS AND SPEEDS - ABRASIVE ENGINEERING

In the transverse grinding process a wheel, substantially wider than the actual cross feed, distributes over its face the developed cutting force, thus permitting higher downfeed rates. The cross feed, which is used in traverse grinding only, is commonly selected to equal a specific part of the wheel width, such as 1/4 to 1/12.

Factors affecting the life of a diamond saw blade

Sawing fine structure, relatively homogeneous granite, may be appropriate to increase the feed speed, feed rate is too low if the diamond blade easily be polished. But sawing UNEVEN coarse granite structure, should reduce feed speed, otherwise it will cause the blade vibration and reduce fragmentation leading diamond cutting rates.

As a rule of thumb, if there are whole or half kernels in your feed, it is probably not ground fine enough, and you may be losing 5 to 8 percent in feed efficiency. Research shows that for every 100 microns over 700 microns, producers lose 1.2-1.4% in feed efficiency and will cost the producer 7-10 lb of additional feed per pig to market weight.
