What are the operating procedures for air flow crusher and vacuum feeder? EPIC Powder Machinery

Let's talk about the operating procedures of jet mill and vacuum machine. The following are the operating procedures of jet mill and vacuum feeder The basic knowledge, principle and characteristics of the air flow mill have been introduced in detail in the small edition, so that everyone has a general understanding of the air flow mill, but not a lot, so we will introduce it next, because its content is not only these, but also other aspects, and it is also very important, so the following is a detailed explanation

After being filtered and dried, the compressed air of the air flow pulverizer is injected into the pulverizing chamber at high speed through Laval nozzle. At the intersection of multiple high-pressure air flows, the materials are crushed by repeated collision, friction and shearing. The crushed materials are moved to the classification area with the updraft under the action of the fan pumping force, and the coarse and fine materials are separated under the strong centrifugal force generated by the high-speed rotating classification turbine, The fine particles that meet the particle size requirements enter the cyclone separator and dust remover through the grading wheel for collection, and the coarse particles drop to the crushing area for further crushing. The wearing parts of the air flow mill have low loss, and all wearing parts are made of high-quality wear-resistant materials at home and abroad, with a long service life. A small number of easily worn parts are made of hard wear-resistant materials, which are small in size, light in weight and easy to replace accessories. The ultramicro pulverizer is composed of a silo, a mechanical pulverizer, an induced draft fan, a cyclone, a vibrating screen, a liquid nitrogen tank, etc. The cryogenic pulverizer system uses liquid nitrogen as the cold source. After the crushed materials are cooled to become brittle and easy to crush at low temperature, they enter the chamber of the mechanical pulverizer and rotate at high speed through the impeller. Under the combined action of repeated impact, collision, shearing, friction, etc. between materials and blades, toothed discs, materials and materials, Achieve crushing effect. 1. Preparation before startup: check whether the main engine, auxiliary engine, pipes and valves are intact and can work normally. 2. Start (1) Turn on the compressor power supply, the precipitator pressure valve, and the main air valve in turn, and then turn on the power switch of the airflow crusher to connect the power supply. (2) Grading wheel starts from zero and gradually adjusts to the specified speed. (3) Turn on the fan, cyclone separator, dust discharge and motor power supply in turn, and then turn on the main power supply of the feeding bin, and set the transformer?? Frequency of the frequency converter, and then start feeding and crushing. (4) The particle size of the finished product can be adjusted by the frequency of the grading wheel and the feeding amount. 3. Shutdown sequence: frequency converter - feeder - main air valve - compressor - grading impeller motor - cyclone dust remover, dedusting discharge switch - fan - main power supply - air compressor. 4. Maintenance (1) The motor should be lubricated regularly, but the grease should not be too much to avoid excessive bearing temperature. (2) The wear of grading impeller, screw feeder and pulverizing nozzle shall be observed, and the belt tension shall be appropriate. (3) After the material is crushed for a period of time, the powder attached to the machine should be cleaned to avoid blockage, which will affect the crushing effect. (4) The filter bag must be cleaned or replaced after being used for a period of time. 5. Precautions (1) During the operation of the unloader, the outlet shall not reach into the hand to avoid accidents. (2) The speed of the impeller shall not exceed the specified value, otherwise the impeller and motor will be damaged if the temperature is too high. (3) The safety valve should be checked regularly to ensure safety. Welcome to choose, the above operating procedures for air flow crusher and vacuum feeder
