In numerous pulverization, Rod Pin Mill Machine of Organic Pigments has become one of the most mainstream pulverization techniques with a small particle size, narrow particle size distribution, high purity, high particulate activity, and good dispersibility. In particular, it is suitable for disinfection of materials such as pulverization drugs.
Rod Pin Mill Machine of Organic Pigments is mainly used for more refined materials. The pulverized particle diameter is 1.5 to 0.005 mm, and the crude material is sieved. The principle of pulverization is substantially the same as the hydraulic level, and the above settlement theory can also be used for airflow classification. However, in the airflow classification, since the density and viscosity of the air are much smaller than the density and viscosity of water, the same particles are more settle more in the air than in the water. Moreover, the density and viscosity of the air varies with temperature and pressure.
In order to cause air flow, wind pulverization equipment typically requires an appropriate fan (exhaust or blast).
When the airflow is classified, the fine particles are typically taken away by the airflow. In some cases, the raw material is sent to the gas stream into a pulverized device.
It is well known that the load of solid particles in air under normal pressure does not exceed 500 g / m3 air. When it reaches 1 kg / m3, the particles fall from the airflow. The load is related to the density and particle size of the particles. When the fine particle material is treated, the load generally does not exceed 200 to 300 g / 3 air. According to this calculation, the volume concentration of the solid in the gas stream is much smaller than 0.03. Therefore, when the airflow is classified, in most cases, it belongs to the free settlement.
The speed required to move the particulate material in the horizontal and vertical directions is relatively large, and the speed required in the horizontal direction is relatively large, and as the particle density increases, for example, for the density 1.5 of the pulverization coal per centimeter. The minimum wind speed is 2 m / sec; a powder material having a density of 2.5 g / cm, the speed is not less than 3.5 m / sec; a powder having a density of 4 g / cm 3, a minimum speed of 4 meters per second. Due to the complexity of the situation, the appropriate airflow rate in each particular situation should be determined by experiments.
In the rising airflow, the airflow speed required to suspend a certain density and particle size is greater than the calculated value of free settling, which is due to the uneven distribution of the airflow along the pulverizing chamber portion.
The ROD PIN MILL MACHINE OF ORGANIC PIGMENTS has the characteristics of high pulverization, high pulverization efficiency, high pulverization accuracy, accurate cutting particle size, and good stability.

Rod Pin Mill Machine of Organic Pigments should be maintained and maintained
1, use Before, check all the standard parts of the equipment to be tightened, the belt is tight.
2, the spindle operation direction must conform to the direction of the arrow shown on the protective cover, otherwise it will damage the equipment, and may cause human damage.
4. Check the hardware such as metal-free materials in the equipment crushing room, otherwise it will damage the tool, affect the equipment operation.
5, the material must be checked before crushing, and there is no metal material hard article to be mixed to prevent crash or cause combustion.
6, the oil cup on the device should often be injected into the lubricant to ensure that the equipment is operating normally.
7. Stopping the feeding before the shutdown, if it does not continue to be used, clear the in the machine.
8. Check the tool with the screen on time is damaged. If it is damaged, it should be replaced first.
9. When using the timing, there is a small oscillation, so it is necessary to connect the handle to the handle to avoid accidents.
The equipment market is rapidly changed. At present, the airflow classifier has certain needs in the market, but the society is constantly evolving, no matter what industry needs to keep pace with the times, they can lead the industry. .
