| Before making ceramic proppant, we need procurement process of raw materials, It has great superiority in rich raw materials and convenient transportation, tested the samples of material regularly from prospecting to inspection and application. It controls the procurement process strictly for the stability of production .
For making ceramic proppant, It adopts the advanced domestic ball grinder auxiliary with raymond mill for milling powder, controls the granularity of milling powder strictly from 350M to 400M. The crude ore has been crushed in each class and batch respectively. It inspects the granularity of milling powder strictly for its quality.
In the mixing process, charging mixture by computer, weighing in electronic scales, mixture ratio is exactly same with required. Controlling the mixing time reasonably from 20 to 30 minutes for the mixing unifity of materials for making ceramic proppant. While making ceramic proppant, we need pelletized it, It adopts the ?1.5 Rotary-type granulator. The workmen has been trained strictly before go on duty. The technics is spraying pelletization. The time of pelletization is 50-70 minutes, making sure the particle within the size range of technical requirement.
After that we need dry it for making ceramic proppant,The tube-type druing kiln controls the humidity of semi-finished products ,drying and dedusting, to be the perfect state for sieving. Sieving is very important for making ceramic proppant. In the sieving process, The combined type drum sieve which was invented by our company can make sieving in multilayers, inspection several times. All of the particles will be controled by the first and second screen of the combined type drum sieve to tally with the size range.
Sintering is very important for making ceramic proppant, Different products adopts different technics. general products is sintered by natural gas in the rotary kiln, The automation cooling, smashing, dedusting, sieving, packing and deliverd to the storehouse. |
