ono method assess clinker

How the method assess clinker quality?
Simply Mr Yoshio Ono the founder describes the main parameters;
- burning rate, rate of heat from calcination to burning zone 850-1450C, the parameter is expressed by alite size, optimum at 20-30 microns.
- birefringence, max temperature that clinker accept at burning zone, optimum at 0.007-0.010.
- burning time, express by belite size is the time length meal at max temperature, optimum at 20-25 microns.
- cooling rate that expressed by belite color is the rate of decreasing temperature from max temperature to 1200C, optimum at clear cooler.

Ono parameters are very important basic method.
