Traditional granulator production technology had the characteristics of low output, low particle hardness,the bulk density not reaching the requirements of customers, cyanuric acid dry rolling granulation technology mainly relied on external pressure, so the material were forced compresses into tablet, block.In rolling process,through the gap of the two relatively rotating rollers, the actual density of the material could be increased 1.5~3 times, so that the granules reached definite strength and bulk density, the cyanuric acid granule yield and the quality of cyanuric acid granules were greatly improved.
