Knife-trimmed mica split from the better qualities of block mica to any specified range of thicknesses between 0.0012 in and 0.004 in (30.5 mu m and 102 mu m).
Industry:Mining
Laboratory apparatus in which mineral particles suspended in water are syphoned through vertical tubes of increasing cross section, the fraction failing to rise under determined conditions of upward flow reporting as a subsieve fraction.

Laboratory screen shaker widely used in screen sizing analysis. Up to seven 8-in round screens are nested on the appliance and given a shaking, rotary, and tapping motion.
Industry:Mining
Laboratory screens of usual 8-in-round (20-cm-round) size, in which the diameter of each new wire is equal to the distance between successive parallel wires. Therefore, in a 60-mesh screen (having 60 wires/in (152 wires/cm) measured along either the warp or the woof) the aperture is a square measuring 1/120 in (0.21 mm) on the side. The meshes used are 5, 8, 10, 12, 16, 20, 30, 40, 50, 60, 70, 80, 90, 100, 120, 150, and 200.
