Based on the experiment, the effects of both the fineness of ground phosphate rock and acid consumption on the property and quality of SSP products are studied. 通过实验研究不同磷矿粉粒度和酸用量对过磷酸钙产品物性和质量的影响。
The result indicates: the finer the ground phosphate rock is, the better the property and quality of SSP; 实验结果:磷矿粉越细,产品物性和质量越好;
On-Line Analysis of Ground Phosphate Rock by Laser Absorption Spectrometry 采用激光吸收光谱法在线分析磷矿粉
Modification of exhaust dedusting in drying of ground phosphate rock 矿粉干燥尾气除尘改造
Effects of Direct Application of Ground Phosphate Rock to Red Soil on Yield increase and Soil Amelioration 红壤上直接施用磷矿粉的增产效果和改土作用
The conclusion is drawn that an effective measure for the classifying selectivity of tiltable plate classifier should ensure the approach both the vertical sedimentation velocity of ground phosphate rock particle and the rising speed of phosphate rock slurry. 试验结果表明,使磷矿浆的垂直上升速度尽量接近欲分级磷矿石颗粒的垂直沉降速度,是控制斜板分级机分级选择性的有效方法。
