Bao Di Project Automated Material Supply System for Environmental Protection Materials

In the field of environmental protection material production, urea granules have been widely used due to their excellent properties. However, their strong hygroscopicity, tendency to clog, and thermal sensitivity have always been technical bottlenecks that automated feeding systems have struggled to overcome. Traditional mechanical conveying methods often lead to material agglomeration and blockage, while conventional pneumatic conveying is prone to urea decomposition due to frictional heating, seriously affecting production efficiency and product quality. The Vige technical team, based on in-depth research on the material characteristics (with a moisture content of ≤0.5% still posing the risk of hygroscopic adhesion), and innovative pneumatic conveying technology, successfully developed the industry’s first dedicated urea granule automated feeding system, achieving breakthrough indicators of conveying efficiency > 98% and damage rate < 0.1%.

Automated feeding system in the chemical industry

Wijay Company has designed an automated material handling system for chemical customers, which enables the full collection, storage, transportation and measurement of materials. This system has saved a significant amount of labor costs and ensured the safety of material supply. The powder logistics used in this project factory include materials with completely different characteristics such as calcium carbonate, calcium sulfate, and industrial boiler ash. Vij’s unique pneumatic conveying technology not only realizes the transportation of multiple logistics through a single pipeline, but also ensures the efficient and stable operation of the entire system, significantly reducing the equipment investment costs for customers.
