Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONIntroduction of petroleum coke into the coal market in recent years has necessitated the use of manyof th
3、e test methods for coal so like data would be available for comparison and blending purposes.TestMethod D409 does not cover petroleum coke in its scope and its statements of precision and bias donot include petroleum coke. This test method provides the procedures and precision and bias data forthe h
4、ardgrove grindability index (HGI) of petroleum coke. Use of this test method or Test MethodD409 produces the same value for the sample of petroleum coke being analyzed.1. Scope Scope*1.1 This test method covers the determination of the hardgrove grindability index (HGI) of those petroleum cokes that

Much of fluid cokes will pass a 0.59 mm (No. 30) sieve. Because of this fineness the HGI value is related toth

Summary of
18、 Test Method4.1 The sample of petroleum coke is reduced (crushed) to produce a high yield of particles passing a 1.19 mm (No. 16) sieveand retained on a 0.59 mm (No. 30) sieve. These particles are reduced in the hardgrove grindability machine according to TestMethod D409. The quantity of particles r
19、etained on a 0.074 mm (No. 200) sieve is used to calculate the HGI of the sample.5. Significance and Use5.1 The HGI is used to predict the ranking of raw petroleum cokes or calcined petroleum cokes in industrial size mills used forcrushing operations. The rankings are based on energy required and fe
20、ed rate or both.5.2 The HGI is also used to select raw petroleum cokes and coals that are compatible with each other when milled together ina blend so that segregation of the blend does not occur during particle size reduction.6. Hazards6.1 Calcined petroleum coke is generally coated with a dedustin
21、g agent to decrease the occurrence and the quantity of dustduring subsequent transporting of the calcined petroleum coke. The dedusting agent is an oil or suitable material. When a dedustingagent is present and is not removed prior to the determination of HGI there can be interference in the sieving
22、 step to measure theportions retained on and passing a 0.074 mm (No. 200) sieve. Removal of the dedusting agent after calcined petroleum coke isreduced to pass the 4.76 mm (No. 4) sieve and before stage crushing to pass the 1.19 mm (No. 16) sieve is required. Suitablesolvents for oil removal are dic
23、hloromethane, dichloroethane and toluene. (WarningSee the appropriate materials safety datasheet.) The solvent used must be removed prior to the reduction to pass the 1.19 mm (No. 16) sieve. Heating to 10 C above theboiling point of the solvent used or application of vacuum is satisfactory for the r
