Most of the product production and processing in the current stage, using Pin Mill Map, the use of Pin Mill MAP is a very common way to process and produce, accompanied by the continuous improvement of scientific productivity, and the technology of classification equipment is also Emergency is imminent. The performance and internal configuration of the grading equipment of the airflow must also keep the trend of the era to continue the upgrade of the product.
PIN MILL MAP 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 particle size is greater than the calculated value of free settling, which isThe speed distribution of the airflow along the pulverized chamber portion is uneven.
The PIN MILL MAP has a wide comminuted range, high pulverization efficiency, high pulverization precision, accurate cutting particle size, and good stability.
