In numerous pulverization, Pin Mill Machine of Wheat Bran has become one of the most mainstream pulverization techniques in a small particle size, narrow particle size distribution, high purity, high particulate activity, and good dispersibility. Especially suitable for crushing drugs such as contaminated materials.
Pin Mill Machine of Wheat BRAN 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 PIN Mill Machine of Wheat Bran has a wide comminuted range, high pulverization efficiency, high pulverization accuracy, accurate cutting particle size, and good stability.
ALPA desulfurizer PIN MILL MACHINE OF WHEAT BRAN Case Sharing: The company is a high-tech company that requires a desulfurizer crusher, investigating a number of powder equipment manufacturers at home and abroad, and finally chose us ALPA Pin Mill Machine of Wheat Bran.
Technical parameters:
Production capacity: 4-5T
Pin Mill Machine of Wheat Bran will produce certain noise during productionThe main reason for generating noise is:
(1) When the coal mill is operating, the operating member drives air to generate a \"whistle\" call:
For the cause of noise, the main solution is as follows:
(1) adding oil to each rotating member, if the bearing and the axis are misalign, adjust the bearing wear, replace the bearing;
(2) The heat generated during the breaking process also produces noise, and cools the cooling of the crushing chamber, the muffler is mounted in the air intake port of the pulverizer; (3) damping the damping pad and other devices.
ALPA technology developed crushing equipment has been applied in many actual engineering cases, providing basic information for objective understanding of jet grading technology.
