crushers, smooth roll crushers, toothed roll crushers, and hammer mills are used for secondary crushing, which further reduces particle size to 3 mm (0.1 in.) or less. For some applications, tertiary size reduction is necessary and is accomplished by means of ball, rod, or pebble mills, which are often combined with air separators.

Pressurized sample suspensions up to 35m1 are bled through a needle valve at a rate of about 1 ml/min. Because the process generates heat, the sample, piston, and cylinder are usually pre-cooled. Typical pressures used to disrupt yeast are 8,000 to 10,000 psi and several passes through the press may be required for high efficiency of disruption.
A sample of the seed to be purchased is chemically analyzed by a chemist licensed by the United States Department of Agriculture. If the seed grade above 100, the ginner receives a premium above the base price. A discount is applied if the seed grade below 100. The grade analysis is based on a random sample of seed drawn from each

(including brokens) obtained from a sample of paddy. The maximum milling recovery is 69-70% depending on rice variety, but because of grain imperfections and the presence of unfilled grains, commercial millers are happy when they achieve 65% milling recovery. Some village type rice mills have 55% or lower milling recovery.
