The crude copper phthalocyanine blue pigment is milled in a production size (2000 gallon) ball mill to make a green shade phthalocyanine blue pigment (beta form). The ball mill is charged with 32,000 lbs. of 5/8 inch hardened steel ball grinding elements and preheated to 120° C with a heat exchange jacket.

From Table 1, it can be seen that the δ-form of crude VBRS has changed significantly when ground for 1 h, with diffraction peaks exhibited in 2 θ =5.5°, 26°, which means that the crystal phase has been partially transformed to the α-form. When ground for 2 h, however, the δ-crystal phase is completely transformed to the α-phase. Further milling, for 5 and 10 h, does not affect the ...
