"In the year 1995, Kuan-Ho furtherly signed a further cooperation contract with Germany OLREFCO, introduced to use Optical Microscope, Laser computerized particle size analyser,Hot Torsion tester, Thermal linear expansion computer testing machine,"
The influences of particle size, calcining temperature, and time on the preparation of lime with high activity from small particles of limestone were studied.
Most biological particulate filters remove particle sizes as small as 0.3 microns.
In general, smaller grain size and greater angularity tend to increase the porosity while an increase in range of particle size tends to decrease porosity.
