Ring Roller Mill for Dyestuff technology is one of the important basic technologies in modern industries. In modern industries, the raw materials that require powder state have a small and uniform particle size and higher purity, and ultrafine raw materials. Its nature changes, which makes ordinary materials have a broader application range,
Ring Roller Mill for Dyestuff 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 settled in the air than in the water. Moreover, the density and viscosity of the air vary 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 product is usually taken away by the airflow. In some cases, the raw material is sent to a pulverized device from the airflow.
As is well known, the load of solid particles in the 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 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 direction 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 pulverized coal and Western / cubic 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 particles size is greater than the free settling.The value is calculated because the velocity distribution of the gas flow is unevenness in the pulverized chamber portion.
The RING ROLLER MILL for Dyestuff has the characteristics of high pulverization, high pulverization efficiency, high pulverization accuracy, accurate cut particle size, and good stability.
