Shandong Erfa production spherical titanium powder special airflow grading machine function
Application of cosmetics in the daily chemical industry contains a large amount of solid powder, such as titanium white powder, calcium carbonate, gas flow milling technology to improve powder structure, improve powder structure, and product performance and product Quality has great improvement.Spherical titanium powder is a very widely wide metal powder. It is a powder metallurgy, alloy material additive. It is also important raw materials such as metal ceramics, surface paint, aluminum alloy additives, electroolers, spray, and plating. In the process of spherical titanium powder, it is generally selected by the airflow classifier. Shandong Erfa is the source of domestic airflow grading machine source manufacturers, the gas flow classifier produced in metal powder, alloy powder and other raw materials The preparation is highlighted and has higher visibility in the industry.
For spherical titanium powder, Shandong Erpi mainly adopts closed-loop airflow classifier, its main role: running in argon contains, will be less than 15 microns The fine powder is separated, the coarse powder discharge port (grading host discharge port) is greater than 15 microns, and the fine powder discharge port (whirlwind separator outlet) is less than 15 microns. The whole machine PLC control has a one-button start, one-button shutdown, manager and operator's operational permissions, and the whole machine has a preparation function and quick replacement argon function, and continuous boot system cooling function. Safety measures take into account the direction of discharge.
Shandong Erfa closed loop gas flow classifier system working principle:
The material is subjected to the automatic feeding device to the classified cavity through the material, and the material is dispersed in the lower part of the grading chamber to satisfy the hierarchical indicator. The powder is divided into a cyclone collector and a pulse dust collector through a division, and the material is collected by replacement tanks. Items that do not meet the grading requirements are discharged directly from the lower graded golden yellow under gravity. They are also collected by replacement tanks. After collecting the material, the gas is collected, the gas enters the ventilator, the Roots fan is exhausted after filtering and cooler, enters the grading area of the grading area under the grading chamber, so that the gas has been running throughout the system. To 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, the inert gas is supplemented to the system. The pressure is increased in the system. The pressure relief valve is automatically opened by pressure detection, and the excess gas is discharged, and the system pressure is always maintained in a balanced state.
The closed-loop airflow classification machine produced by Shandong Erfa can not only be used in the fine grade of spherical titanium powder, but also for the grading segment of other flammable and explosive oxide powder, in the agglomerate, and the aggregate powder has hit The function of dissemination, has been confirmed in many practical cases and has been well received by the majority of users.
For AlPa powder, the artisan spirit is not just a concept, attitude and inheritance, and is a gene that implant the company R & D, manufacturing, marketing, service and culture. A well-known craftsman, for decades, such as the pursuit of professional skills, more purely, relying on drilling and inheritance, explaining the spiritual connotation of the craftsman with a focus and persistence, and created another "alPa manufacturing".
