What are the basic requirements for the working medium gas of the air flow pulverizer? Umico Powder Machinery

The air flow pulverizer itself is a relatively closed system, and there is no certain communication with the outside during the production process. We only need to control two pairs of contact points when using it. If we add a feeder and the outlet after crushing, it can be very good to ensure bacteria free docking and material transfer, which can save a lot of costs. An important problem for sterile crushing fabrics is that,

Airflow mill

If the fluidity of the air flow mill is not very good, the materials adhered to the pipes and the inner wall may not be discharged from the equipment in time, resulting in the loss of materials during the cip process. Therefore, the polishing effect of the air flow mill

inner wall should be as good as possible, 0.1 or 0.2 is OK

Another problem is the cip process. If the materials form relatively hard lumps in the crushing disk, it is impossible to use manual work to polish and clean them. It needs manual assistance to clean and then do the cip. Air flow pulverizer constitutes a complete set of pulverizing system. After being filtered and dried, the compressed air is injected into the crushing chamber at high speed through Laval nozzle. At the intersection of multiple high-pressure air streams, the material is crushed by repeated collision, friction and shearing. The crushed material moves to the classification area with the rising air stream under the action of fan pumping force. The high speed airflow formed by mixing the high-pressure gas (compressed air, superheated steam or other gases) sprayed from the periphery of the crushing chamber with the solid material particles sent in< Br/>The basic requirements for the working medium gas of the airflow crusher are: oil-free, dry, with a pressure of 06~1.2MPa, and the medium gas can be air, inert gas, superheated steam, etc. Therefore, the gas compressor can be an air compressor, a nitrogen compressor, or superheated steam generated by the boiler. There are two types of compressors: oil lubricated and oil-free. Oil lubricated compressors include piston type and screw type, and oil-free compressors include piston type and vane type. If oil lubricated compressor is adopted, liquid vapor separator and multistage oil filter shall be added in the air supply line. Gas dryers include refrigerated wet dryers (atmospheric dew point 19 ℃) and adsorption dryers (including heatless regenerative dryers and micro heating regenerative dryers, atmospheric dew point 40 ℃)
