A pneumatic pulveriser unit in a hammer mill is designed to finely grind spices using a combination of mechanical impact and air flow. In this setup, the hammer mill’s high-speed hammers break down the spices, while a pneumatic system uses air pressure to transport and further refine the ground material. The pneumatic system helps to move the particles through the mill and separates finer powders from coarser ones. This type of unit is advantageous for achieving a consistent and precise grind, as well as for handling larger quantities of spices efficiently. It is commonly used in both industrial and commercial settings where high throughput and quality are essential.
