What are the material requirements for a rotary drum granulator?

图片
As a core piece of equipment in the production of compound fertilizer s and organic fertilizers, the rotary drum granulator is widely used in large-scale production due to its simple structure and high capacity. Its granulation effect directly depends on whether the material characteristics meet the standards. To ensure efficient and stable operation of the equipment and produce granules with uniform particle size and qualified strength, the material must meet four core requirements: particle size, moisture content, adhesiveness, and component compatibility. None of these can be neglected. A reasonable particle size distribution is the foundation of granulation. Rotary drum granulation relies on a "snowball" granulation principle, requiring a scientific ratio of coarse and fine materials. Fine powder (particle size ≤ 0.15mm) should account for 60%-70% to quickly absorb binders and form particle nuclei; coarse powder (particle size 0.15-0.5mm) should account for 30%-40% to fi...

Working Principle of a Double Roller Press Granulator

图片
A double roller press  granulator is a highly efficient and energy-saving dry granulation equipment, widely used in chemical, fertilizer, and building materials industries, playing a crucial role, especially in fertilizer production line s. Its core principle is to use high-pressure mechanical extrusion to shape powdery materials through intermolecular forces, eliminating the need for additional binders and achieving green and efficient granulation throughout the process. The core power source for the equipment is the transmission system. An electric motor drives a pulley, which, after being reduced in speed and torque by a reducer, drives a pair of parallel high-pressure rollers to rotate at a relatively uniform speed. The transmission methods vary slightly between different models; some use split gears to achieve double-roller linkage, while others are directly driven by a reducer with dual output shafts, ensuring synchronous rotation and balanced pressure between the two roller...
