Silicon fine powder is made of natural quartz (SiO2) or molten quartz (natural quartz high temperature melting, amorphous SiO2 after cooling), ball mill (or vibration, air flow), flotation, pickling, high purity water Treatment of micropowder processed by multi-course process. Silicon fine powder is a non-toxic, odorless, non-polluting inorganic non-metallic material. Since it has excellent temperature resistance, alkali corrosivity, poor thermal conductivity, high insulation, low expansion, chemical performance, high hardness, and widely used in chemical, electronics, integrated circuit (IC), electrical appliances, plastics , Paint, advanced paint, rubber, defense and other fields. With the rapid development of the high-tech field, silicon micropowder will also enter the new historical development period.
High performance, high purity, high melting spherical titanium powder is an important raw material for the production of key parts of the air engine. In the processing of spherical titanium powder, the closed-loop airflow classifier is one of the commonly used equipment, which is the main function to separate the spherical titanium powder in an argon comprise a fine powder of less than 15 microns.
The closed-loop airflow classifier is an inert gas protection grading equipment, by implanting argon into the equipment system, driving the air in the system, so that the grading processing is in the state of argon protection. The coarse powder discharge port (grading host discharge port) is greater than 15 microns, and the fine powder discharge port (whirlwind separator exit) is less than 15 microns. The whole machine is controlled by PLC, with one-click start, one-button shutdown, manager and operator's permissions, and the whole machine has a preparation function and quick replacement argon function, and the continuous boot system cooling function.
The closed-loop airflow classifier is: the feedstock is subjected to the automatic feeding device to the classified cavity by the material, and the material fluids into the grading area, and the powder to satisfy the classification indicator is over the division wheel. To the cyclone collector and pulse dust collector, and collect the material through the conversion tank. The material that does not satisfy the grading requirements is discharged directly from the lower hierarchical region under gravity, and is also collected by the conversion tank. After collecting the material, the gas is collected, the gas enters the ventilator, the Roots fan is exhausted after the gas is filtered and the cooler, enter the grading area of the grading area, so that the gas has been in the entire system. Work, form a closed loop system. At the same time, monitoring systems such as oxygen content, pressure, pressure difference, and temperature is provided on the pipeline. When the oxygen content exceeds the standard, inert gas will be supplemented to the system.The pressure is increased in the system, and the pressure relief valve is automatically opened by pressure detection, and the excess gas is discharged, and the system pressure is maintained in a balanced state.
Tablet-shaped gas flow grading machine processing spherical titanium powder can effectively prevent dust explosion and dust leakage, is a safe, environmentally friendly equipment, currently in many metal powder processing companies, closed-loop airflow classifier can be considered Shandong El Pie, Shandong Erpa is a manufacturer specializing in the production of gas flow grading machine, airflow pulverizer, inert gas protection airflow pulverization unit, is a research and development and production base with technical advantages in China.
For many years, AlPa Powder Technology has always guided the manufacturing quality of industrial powders, and continues to precipitate, creating the processes, welding automation, and molding process standards. Professional manufacturing levels meet the pursuit of customers "safe, efficient and energy saving", so that every ALPA gas flow crusher has become the superiority of contributes.
