With the rapid growth of China's economy, high-energy mining machinery industry, especially Pin Mill will have a huge development space, and various mineral powder products will develop rapidly. In order to ensure sustainable development, green, environmentally friendly, healthy bed jet rubbing equipment and products more extensive in the entire mineral powder industry. When applied to people's lives, it is necessary to optimize the use of equipment technology.
Pin Mill 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 is due to airflow edgeThe speed distribution of the pulverized chamber portion is uneven.
The PIN MILL has the characteristics of high pulverization, high pulverization efficiency, high pulverization accuracy, accurate cut particle size, and good stability.
ALPA lithium iron phosphate PIN MILL case sharing: This customer is expanding in the production process, through comparison discovery that the performance of our AlPA's lithium iron phosphate special crusher is no longer more than other powdered equipment companies at home and abroad. The same type of equipment is poor, even in some aspects there is also a unique advantage. After experimenting, the company purchased PIN MILL.
