I. Process Overview
The sulfur powder production line’s pulverizing system is specially designed and developed for materials that are flammable, explosive, or easily oxidized. It builds upon a multi-stage mechanical pulverizer powered by a conventional air source and a vertical turbine high-precision classifier. By modifying the composition of the air source and altering the inlet and outlet ductwork of the equipment, as well as enhancing the sealing technology of the equipment, this system achieves superior performance tailored to these challenging materials.
The entire system of the equipment uses nitrogen or carbon dioxide gas as the pulverizing working medium. The complete set of equipment comprises an inert gas source, an oxygen content analyzer, an air inlet piping system, a closed-loop feeding system, a vertical turbine classifier, an induced draft fan, a sealed discharge mechanism with gas置换 function, an antistatic pulse-jet dust collector, an inert gas replenishment unit, and a cooler. The outlet of the induced draft fan is connected to the air inlet of the cooler, and the air then returns to the inlet of the pulverizer, ultimately forming a closed-loop nitrogen circulation system.
II. Working Principle of the Series Inert Gas Flow Pulverizer
The inert gas-protected ultrafine pulverization system uses inert gases such as nitrogen, carbon dioxide, and argon as the gas-stream grinding medium to achieve ultrafine pulverization of materials. This system mainly consists of a compressor, an air storage tank, a material hopper, a pulverizing main unit, a cyclone separator, a dust collector, and an automated control system.
When the system is powered on, an inert gas is continuously introduced into the system to displace the air until the oxygen content throughout the entire system reaches the preset value. Then, the feeding device automatically starts, evenly introducing the raw materials into the grinding chamber of the main grinder. Compressed inert gas, passing through a cooling system in the grinding chamber, causes the material to undergo intense impacts, collisions, friction, shearing, and compression as it interacts with the high-speed rotating components and particles, thereby achieving ultrafine pulverization. The pulverized material rises with the airflow into the classification chamber for particle size separation. Fine particles meeting the required specifications enter the grading wheel and are collected by a cyclone separator and a dust collector along with the airflow. Material that fails to enter the grading wheel is returned to the grinding chamber for further impact and pulverization. The purified gas, after being filtered, is returned to the compressor’s intake port and reused in a closed-loop cycle.
III. Application Fields
Primarily used in military research institutes, metal powder processing, pharmaceutical ultrafine powders, and other related fields, this system operates with stability, safety, and reliability. Typical materials include sulfur powder, aluminum powder, manganese powder, and various other powders used in powder metallurgy.
