With the development of society, the application of Hammer Pulverizer with shell has become more large.
Hammer Pulverizer With Shell 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 Hammer Pulverizer with shell has a wide comminuted range, high pulverization efficiency, high pulverization accuracy, accurate cutting particle size, and good stability.

How to control the particle size size?
The smaller the particle size of the raw material, the higher the pulverization efficiency, the greater the particle size of the raw material, then the crushing effect is relatively low. In the case of crushing pressure and feed pressure, reduce the feed speed product will be finer, and improve the feed speed product will become thick. In the case of a feed rate, the particle size of the pulverized pressure is improved, and the pulverization pressure is reduced, and the product will become thick.
The company produces a variety of Hammer Pulverizer with shell and airflow mills, complete test methods and sample equipment and laboratory equipment, and the production of crushers are widely used in chemical, pharmaceutical, minerals. Electronics, pesticides, ceramics and other industries. Welcome to contact us if you need to buy products.
