The ultrafine ground jujube powder was prepared at ultra-low temperature using an ultrafine grinder PLS-10L (Jinan Preshen Machinery Equipment Co., Ltd., Jinan, China), and then sieved through 200 mesh, 270 mesh, and 800 mesh sieves, yielding ultrafine powders denoted as S1, S2, and S3. All jujube powders were stored at −20 °C until analyzed.
It is therefore used as a grinding aid for the wet ultrafine grinding of limestone. The rheological behaviors of ground limestone slurries vary with grinding from a starting dilatant flow-ability to a resulting pseudoplastic one with an evident Casson yield stress in combination with a thixotropic character.
