Horizontal Single Classifying Wheel Air Classifier of slag

Horizontal Single Classifying Wheel Air Classifier of slag is a very common and common pulverizer. It has a wide range of applications involving many industries.

Horizontal Single Classifying Wheel Air Classifier of slag mainly used for processing finer material. The fractional particle size 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 grading equipment typically requires an appropriate fan (exhaust or blast). When the airflow is classified, the fine particles are usually taken away by the airflow. In some cases, the feedstock is sent to the grading device with the airflow. It is well known that 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 directions is relatively large, and the speed required in the horizontal direction is relatively large, and as the particle density increases, for example, for puls with a density of 1.5. Gram / 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 water flow rate required to suspend a certain density and particle size is greater than the calculated value of the free settling, which is due to the uneven distribution of the airflow along the graded chamber portion. The Horizontal Single ClassifyingWheel Air Classifier Of Slag has the characteristics of high grading range, high grading efficiency, high level precision, accurate cut particle size, and good stability.

Horizontal Single Classifying Wheel Air Classifier of Slag Principles: When the compressed gas passes the injection of the injector, the pulverized raw material enters the pulverizer, there are multiple pulverized nozzles in the pulverized room, and the supersonic air flow is sprayed. The airflow high-speed impact and the material collide with each other, friction and pulverize, the grading tube separates the thicker particles, and the crude particle circulation continues to be pulverized, and after the internal closed circuit circulation is pulverized, it will finally obtain uniform distribution in the discharge port. pink. 1. Suitable for dry ultra-micro processes. Due to the large impact speed, it can be more than 2.5 mep, in general, it is easy to obtain 1-10 micron particles, depending on the properties of the material, it is possible to obtain less than 1 micron particles. 2. Because there is a closed circuit classification mechanism inside the pulverizer, the product is thick The particles constantly circulate, and thus the particles are uniform and the particle size distribution range is obtained. 3, the equipment has the advantages of short smashing time, simple structure, convenient operation, small area, low noise (72 decibel) and no vibration. 4, the efficiency is high when pulverization, can be pulverized, and the purity of the pulverized product can be maintained.
