The experimental airflow pulverizer is a device that can separate solid powder into fine particles. Its main principle is to use high-speed airflow to throw the powder onto a high-speed rotating impeller for crushing, and then separate it into the required powder in the classifier through centrifugal action. Before operating, it is necessary to master the principles and related knowledge of the experimental airflow pulverizer.
1、 Preparation work
1. Place the experimental airflow pulverizer on a flat surface in the laboratory and ensure that it can be powered normally;
2. Select different sizes of crushing noise as needed, grind them into the desired particle powder, and screen them;
3. Start the fan of the device to ensure sufficient airflow is generated;
4. After all the indicator lights of the device are turned on, proceed to the next experimental operation.
2、 Operation steps
1. Open the feeding valve of the equipment and add the prepared powder into the crushing chamber to ensure even feeding;
2. Adjust the coordination between the feed valve and the airflow valve, control the feeding speed and the flow rate of the inlet and outlet airflow;
3. Separate the crushed particles through a separator to obtain the desired particle size powder;
4. Close the feeding valve of the equipment and stop feeding;
5. Stop the fan and clean up any remaining powder;
6. Turn off all devices and disconnect the experimental airflow pulverizer from the power supply.
3、 Precautions
1. When adding materials, they should be evenly distributed to prevent blockage and overload;
2. For different powders, it is necessary to adjust different feed rates and airflow velocities;
3. Before conducting important experiments, some small experiments can be conducted to adjust parameters in order to obtain better experimental results;
4. Clean the equipment promptly after use to prevent excessive powder from causing blockage or affecting the next experiment;
5. During the operation, pay attention to safety, avoid contact with rotating parts, and wear appropriate protective equipment.
In short, the experimental airflow pulverizer is an experimental instrument that requires scientific and standardized operation. By following the steps and precautions introduced in this article, one can better grasp the essentials of operation and ensure the smooth progress of the experiment.
