How to produce high-quality oil fracturing proppant

Oil fracturing proppant production process, increase the moisture in the spray granulation process required to evaporate the moisture also increase, which will cause the particles to form a small hole in its strength reduces water evaporation fracking process , while there will be particles of roundness unbalanced shape, that is not too small particles of irregular shape. Under the formula remains unchanged, if the water is less than the mud 20mas%, because the flow is too low and will not be out of the ball mill, ball mill will be trapped in the mud. Some will even out of stagnation in the pipe mill and mixing tank between, so that production can not be along the line; if the water is greater than the mud 28 mass%, so all of them can flow into the mud stirred tanks. However, due to excessive moisture, proppant production in spray granulation process smaller particles, about 90% of the particles between 0.1-0.2 mm, reach the next step process requirements, while extending the time required for dehydration, cause the particles are not completely dry falls splice apparatus, causing mutual bonding between the particles and the particles together to form larger irregular particles, can not play the advantages of spray granulation, under the influence of anterograde step process.
