Super-micro gas flow grinding is made of a large part of a crusher, a cyclone separator, a pulse dust box and a fan, has a variety of overall performance, production process, uniform, no screen, non-mesh, uniform particle size. Continuous progress. It utilizes the relative movement between the active gear disc and the fixed tooth disc, or the gas high speed flows the material to obtain the material to teeth impact, friction, and materials from each other, and the powder is pulverized by the rotating centrifuge and the air machine. Enter the cyclone separator, then passed through the shutter, dust into the pulse dust cleaning tank, and the filter is adjusted by filter cartridge and recovery. The whole machine is designed according to the GMP standard, all of which are made with stainless steel materials, and there is no dust in the production.In the preparation of powder processing, the figure of the airflow classifier can be said to be ubiquitous, and its main function is to separate the powder after ultrafine pulverized powder, or acquire one of the particle size sections. The advantage of the airflow classifier in the dry classification is that the grading accuracy is high, the efficiency is high, does not produce pollution, not warming, and is therefore widely used in various fields. However, there are also some special powder materials, such as easy oxidation of iron powder, flammable and explosive magnesium powder, aluminum powder, etc., which uses a general airflow classifier to use a general airflow classifier to be unsuitable. Shandong Erpai is targeted to the flammable and easy-to-oxidized oxidation, and the ordinary high-end vortex gas flow classifier increases the nitrogen protection system, explosion-proof system, and forms a new inert gas protection airflow classification equipment, in flammable and explosive oxidized materials. Preparation has a special advantage.
The advantage of increasing nitrogen protection after the airflow classifier is the following points: 1, isolated oxygen. Before the equipment is started, the air in the closed circulation system is started, and the air is closed, and the discharge system can be replaced with a small amount of air brought by the addition and discharge process, and maintains the content of the system in the system.
The oxygen content tester is continuously monitored in the gas stream, and nitrogen is added immediately when it exceeds a certain degree, so that the oxygen content is maintained within the safety production standard.
2, control the gas powder concentration. The equipment is supported by the feeding system, which is fully closed, uniform, and is controlled by the control cabinet. Fully enclose the effect of isolating oxygen, uniform speed, controls the material concentration inside the added device, and can be arranged any.
Uniformly addedThe material inside the device is accumulated inside the device, and the security is not guaranteed. Therefore, the device profile, such as the bending angle of the pipe; the shape of each component is scientifically calculated, and the dead angle inside is eliminated, and the powder is not accumulated in the pipe through the high-speed airflow through the equipment.
3. Release static electricity and eliminate the source of the source. The pulsed anti-blow collector can eliminate static electricity in time, while ensuring the pulse clear ash clean thoroughness. The equipment is all metal components, all grounded to try to release powder static electricity.
4, circulating air cooling. Because the system is a closed circuit loop system, there are multiple moving parts inside the device, and a certain temperature is generated in the high speed movement, while the temperature is critical to safety in the machining. Therefore, a heat sink cooler is installed on the pipe, which can effectively reduce the safety hazard caused by the equipment for a long time or in high temperature environment.
5, explosion-proof. The whole system has explosion-proof holes in different positions in the whole line, which minimizes the loss during the bursting and explosion caused by the internal pressure and concentration of the system.
The motor and other devices used in the whole system are explosion-proof motors, and the sealing performance is better and effectively reduces the accumulation of dust.
6, emergency stop. The equipment emergency shutdown trigger switch is connected to the oxygen content tester, and the oxygen content concentration monitors by the oxygen content tester has not reached the preset value in a predetermined time, triggered emergency shutdown, the equipment stopped, the introduction of the wind, the grading machine Delayed, the nitrogen supplement system continues to work until the manual shutdown.
The inert gas protection airflow classifier is currently widely used in various fields, especially in the metal powder processing industry, and its applicable typical materials are: cobalt powder, tungsten powder, zinc powder, reduction iron powder, Nickel powder, tantalum powder, selenium powder, copper powder, magnesium powder, tin powder, aluminum magnesium alloy, titanium alloy, stainless steel powder, spherical aluminum powder, sheet-like aluminum powder, carbonyl iron powder, etc. The inert gas protection airflow classification model produced by Shandong Erfa is FWDB, which is fraudulent to FWDB-100, FWDB-200, FWDB-400, where FWDB-100 is a small laboratory model.
