Test method | 1. Particle size distribution: test by UK Malvern Company Micro analyzer 2.Specific surface area: average particle size transform, unit 1g powder relative area 3. Average particle size: particle size distribution calculate particle median 4. 325mesh residue: put 100g into 325mesh screen mesh filtering, calculate percentage. 5. Apparent specific gravity: put 50g sample into 100cc measuring cylinder with scale, fall down 100 times at 5cm height get the test result. 6. Moisture: put 5g sample into moisture analyzer, under 150 degree Celsius after 6 minute, then test it. 7. Setting volume: put 15g sample to 100cc cylinder, input water to 100cc, then sharply shaking, be motionless for an hour, then test it (20 degree Celsius) 8. Raw material of grinding: limestone, calcite, dolomite, talc, barium sulfate, wollastonite, brucite, calcium hydroxide, gypsum, clinker, phosphates etc. chemical material and minerals. |
