rock phosphate grinding mesh size

Particle Size of Rock Phosphate and Microbial ...

1986-1-1  The solubilization of rock phosphate of varying particle size, caused by inoculation with efficient solubilizing Aspergillus awamori and Pseudomonas striata was investigated in culture medium. The studies clearly showed that maximum phosphate was solubilized when rock phosphate particle sizes between 30 to 59 and 60 to 99 mesh were used.

Rock Phosphate Grinding In Udaipur

May 01, 1980 In all the experiments the rock phosphate samples of required mesh size were prepared by grinding the lumps of Udaipur rock phosphate obtained from mines. Three different mesh size samples were prepared, of 50, 100 and 200 mesh sizes (BSS). The Udaipur rock phosphate used in these observations has the composition shown in Table 1
