The airflow crusher uses a high -speed airflow to drive the material to make the material particles hit each other and shear to achieve ultra -micro crushing purposes. Because of its excellent crushing effect, it is favored by powder manufacturers in various industries. Typical materials of air flow crusher are: super hard diamonds, silicon carbide, metal powder, etc., high -purity requirements: ceramic color, medicine, biochemical, etc., low temperature requirements: medicine, PVC. By changing the ordinary air from the gas source to the inert gas such as nitrogen and carbon dioxide gas, the aircraft can be a inert gas protection equipment, which is suitable for crushing and grading of flammable and explosive, oxidation and other materials. The safety problem of airflow crushing machines to make ultra -fine powder includes pneumoconiosis and dust explosion. The dust particles obtained by the airflow crusher sample are basically below 5 \u0026 mu; m, while the dust below 5 \u0026 mu; the dust below the m is the most harmful to the human body. Therefore, the chance of using the airflow crusher sample operator will increase significantly. At the same time, the dusty clouds may occur after the dust spreads in the air on a large scale, and the dust explosion may occur. Because the dust particles that are not captured during the process of air flow crushing machine have the appropriate particle size and distribution status: the general particle size is less than 5 \u0026 mu; The consequences of dust explosion are also extremely serious. If there is enough ignition air around these particles and has its minimum ignition energy, then the dust explosion is prone to occur. And the shock wave caused by the explosion of local dust clouds makes a large amount of deposit dust fly and mix with the air, which may also form a second explosion. Because the dust explosion has the characteristics of large energy, severe damage, and short explosion time, it is easy to cause incomplete combustion, which causes a large amount of carbon monoxide gas to poison personnel. Therefore, the consequences of dust explosion are also extremely serious. What time does the air flow crusher need to pay attention to in daily maintenance? 1. During the production process, the bearing of the bearing of the airflow must be checked frequently. When the temperature rise exceeds 50 ° C, it should be stopped to check it. The reason is that the reason is to eliminate the failure. 2. When the airflow crusher runs, the transmission leather is easy to extend. Pay attention to adjust the proper tightness of the belt to ensure the working life of the belt. 3. Easy -to -prone parts should be checked frequently to ensure the quality and production of production in time. 4. The blade and lining should be checked frequently. If the productivity decreases after wear, the particle size will be changed after the particle size becomes rough. 5. The host and classification flow bearing are lubricated, and the No. 2 special lipid is used, with a degree of 265-295. 6. The fat replacement period of the bearing of the airflow crusher is 2000 hours. Causes that the temperature of the bearing is too high. 7. The spiral feeder's fat change period is 4000 hours, and Gapita calcium lubrication is lubricated. In fact, each mechanical and equipment is dangerous when used, as well as fluidized bed air flow crusher. This requires us to master its usage methods. Standardize operations and scientific maintenance to minimize the risk probability.
