【Ten Years of Rapid Development in Chemical Equipment】Large-scale Rotary Granulation and Drying Machines for Calcium Chloride Dihydrate, 1051–2022

Thread Content

Ten years of rapid development in chemical technology – praise for the prosperous and strong China. This is just a starting point; more participation from everyone will make things even more lively. HaiChuan becomes even better with you here; we welcome everyone to join in the forum discussions. Be careful with fire as the heat increases in July. --------------------------------------------- In November 2022, the rotary granulation and drying machine for calcium chloride dihydrate, undertaken by Shandong Tianli Energy Co., Ltd., which is part of Shandong Science and Innovation Group (hereinafter referred to as “Tianli Energy”), was successfully lifted into place at Shandong Haihua Co., Ltd., marking the official start of the full installation process. Designed with a production capacity of 80,000 tons per year, this dryer set was the first in China to employ rotary granulation technology for large-scale calcium chloride dihydrate; it represented an innovative breakthrough in rotary drying technology for converting calcium dihydrate in sheet form into calcium dihydrate in granular form. Compared to anhydrous flaky calcium chloride, hydrated spherical calcium chloride has advantages such as better flowability and reduced tendency to caking; as a result, it is more widely used and offers better cost-effectiveness. Traditional production facilities for anhydrous spherical calcium chloride use high-tower granulation or fluidized-bed granulation techniques; the resulting product is prone to fragmentation, and the production process lacks continuity. The rotary granulation technology developed by Tianli Energy uses calcium solution at a concentration of 69% as raw material. Compared with other technologies, it offers advantages such as a stable production process, high balling efficiency, and low energy consumption, making it an effective tool for the transformation and upgrading of products in the calcium chloride industry.
