Factors to be controlled and paid attention to in dry roll granulation technology
Date:2020/07/22
Compared with wet granulation, dry granulation of roller press granulator is a simpler and continuous method, which is often used as granulation equipment in organic fertilizer machine. In wet granulation, the granules are prepared by mixing, granulating and drying. In dry granulation, the process of fertilizer production is relatively short, because there is no need to combine and dry the prepared materials with water. The steps of granulation are mixing, rolling and grinding, which requires less fertilizer machine, time and energy.
Roller pressing is a simple dry granulation method, but the control and optimization factors in the production of roller press granulator must be considered. For example, rolling, roll speed and feed rate of raw materials determine the product properties and final particle shape. They affect the quality of the product, such as the density, fluidity, compressibility and pressure capacity of the particles, as well as the tensile strength of the particles.
