The machine has a comminuted host, a cyclone separator, a pulse dust box, and the like. The material is subjected to a pulverized chamber by the addition of the feed, and the high-speed rotating hard alloy blade is pulverized, and the pulverized fineness can adjust the distance from the hierarchy and the hierarchical disc to achieve the desired fineness, and the smash of the material is turned from heart and the fluid. The role enters the cyclone separator, and then the dust is discharged through the shutter, and the dust enters the pulse dust box and is filtered after filter cartridge. The machine is designed according to the "GMP" standard, all of which can be manufactured in 304 stainless steel materials, and there is no dust in the pulverization process.
Airflow grading refers to a particle hierarchical operation that utilizes particles in a sedimentation rate (see settlement) in the airflow. The gas stream entrained powder particles is reduced by reducing the flow rate, changing the flow direction, so that the fine particles are taken away, thereby separating the coarse fine powder. The airflow classifier is a professional equipment made of this mechanism. In powder processing, it has become a common processing equipment.
The general airflow classifier can make the material freely adjusted between 1-74 micrometers, obtain a granularity section or a thick separation, a cassette, and a high level of grading accuracy, high efficiency. Shandong Erpa is a professional airflow classifier manufacturer. In 20 years in business development, Shandong Province has accumulated tens of thousands of successful cases, which encompass all dry materials. However, the physical properties of different materials are different, including flammable and explosive oxidation materials such as cobalt powder, sulfur, aluminum powder, zinc powder, silicon powder, magnesium powder, iron powder, pulverized coal, carbon, etc., for this Properties of materials, the airflow classifier with ordinary air is obviously inappropriate, and the explosion accident or material is oxidized during processing.
Shandong Erfa face this material, developing explosion-proof anti-oxidant airflow classifiers that produce inert gas as media, which is specifically used for flammable and explosive essentials. This inert gas protection airflow classifier has been favored by numerous processing companies, especially for metal powder (cobalt powder, tungsten powder, zinc powder, reduction iron powder, nickel powder, tantalum powder, selenium powder, copper powder, Machine powder, tin powder, aluminum magnesium alloy, titanium alloy, stainless steel powder, microcolite aluminum powder, sheet-like aluminum powder, carbonyl iron powder, etc.) have unique advantages.
The equipment characteristics of the inert gas protection airflow classifier are:
1. Using full-closed production, completely isolated air, preventing chemical reactions in contact with air.
2. Take a multi-point explosion-proof structure design, minimize hazard coefficients, so that safety production is greatly guaranteed.
3. The gas concentration is detected by a dedicated device, fully automatically realizes the automatic replenishment of inert gas and internal pressure adjustment.
4. Increase the cooling design, reduce the internal circulation temperature of the equipment, and make equipment performance more stable.
The inert gas protection airflow classification model of Shandong Erfa is FWDB-400, and the inertial medium used is nitrogen, helium, argon, carbon dioxide, and the like. Among them, nitrogen is a commonly used inerting medium. Under normal circumstances, electrostatic sparks have lost ignition capacity in nitrogen, but some metal powder can also be combustible in nitrogen, such as magnesium powder, must be protected by argon or helium.
ALPA Powder Technology has been born in 20 years, and has been adhering to the scientific management model of modern enterprises. He insists on "piety, fine, strict, harmonious" as spiritual concept, and put "pursue excellence, casting dawn brand. , Revitalize the national industry "as the tenet of a strong development.
