The explosion-proof function of the airflow pulverizer is its unique advantage

　　Innovative food development, such as nano-selenium and zinc food, functional health food, entertainment and leisure food, life-saving and military food, nano-bio-conserved agent, etc. have an independent, novelty and other innovative food research and development, Ultrafine pulverization and nanotechnology in the air flow.

　　The most frequent contact with powder processing enterprises is a variety of ultrafine powder, which can be used in different fields to create a variety of precision elements or high-end products, and the value is very high. However, the drawbacks of ultrafine powder are also existing, that is, it is easy to cause safety problems, including respiratory dust and dust explosion. Therefore, for the preparation of ultrafine powder, it is one of the standards of testing equipment performance. The airflow pulverizer is used as a common equipment for powder processing, and there is also its uniqueness in the anti-dust pollution and dust explosion.

　　Currently, the new security explosion-explosive airflow pulverizer is R & D in response to the dust explosion. It is based on the general fluidized bed airflow pulverizer, and the gas source from ordinary The air is replaced with an inert gas, and the equipment airhead is connected to the end tail of the air, which constitutes a closed circuit loop system, which allows the powder raw material to always be in an inert gas protection during processing, effectively separated from oxygen in the air and eliminates the fire source. The purpose of achieving explosion.Explosion-proof airflow pulverizer is in use, also need to follow the following "safe operation" rules:

　　(1) Check all circuits and electrical components of the airflow pulverizer to determine if it can work properly.

　　(2) Check if the airflow pulverizer has been grounded to avoid electrification of the shell and the danger of electric shock.

　　(3) Whether the machine spindle is smashed, whether it should be handled in time.

　　(4) Whether the machine has an abnormal situation during the operation, if the check should be stopped immediately.

　　(5) Check if the blade is fastened, whether the blade gap meets the specified standard.

　　(6) Before use, it is necessary to check if the duration is filled with debris or miscellaneous materials. If so, it should be removed in time.

　　(7) The pulverizer should work properly before starting the feed.

　　(8) The feeding should be stopped before the pulverizer is parked. Wait until the machine is completely unloaded to stop.

　　(9) The feeding should be uniform, do not excessively, to avoid increasing the burden on the machine.

　　(10)During operation, the airflow pulverizer cannot be cleaned, overhaul, etc.

　　Shandong Erfa production explosion-proof airflow pulverizer model is FW series, can be applied to pulverization processing of flammable and easy to oxidize raw materials, equipment consisting of nitrogen compression system, nitrogen filter system, crushing system, classification system , Collecting system, plus, unloading system, nitrogen purity test supplementary system, nitrogen system, and electrical control system composition. The production and manufacturing process of complete equipment is a mature technology, reliable quality, and stable performance. Wide application has been widely used in metal powder, volatilized raw materials and flammable and explosive materials.
