Micro Steam Jet Mill Classifier is a very common and common pulverizer. It has a wide range of applications involving many industries.
Micro Steam Jet Mill Classifier is mainly used for more refined materials. 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 product is 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 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 water flow rate required to suspend the particles having 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 grading chamber portion.
The Micro Steam Jet Mill Classifier has the characteristics of high grading range, high grading efficiency, high grading accuracy, accurate cut particle size, and good stability.
Now let's take a look at the performance advantage of Micro Steam Jet Mill Classifier!
Secondly, the grade grade product of this classification machine is adjustable, and the replacement is also very convenient.
Moreover, due to the fluid performance, the grading efficiency of the ultrafine airflow classifier will be high.
Not only that, the classifier also adopts high quality production materials, so the wear resistance of such grading machine equipment is also very good.
Now let's talk about the troubleshooting of Micro Steam Jet Mill Classifier.
Micro Steam Jet Mill Classifier Troubleshooting:
1 It will cause feedback. When this happens, you should find out the cause, then take elimination measures, or remove the valve, replace the powder bag, improve the breathable, or replace the hammer head.
2, bearing overheating: When the bearing lubrication is poor, the damage or the spindle bend, the rotor is severely imbalance, and the belt is too tight and the bearing is overheating. By replacing the lubricant, replace the bearing and the spindle, the balance the rotor and the adjustment belt are elastic, the bearing can return to normal state.
3, strong vibration of airflow pulverizer: Installing a hammer is wrong, the corresponding weight deviation of the two groups of heavy hammers is too large, the bearing is damaged or the spindle is bent, and the foot is connected to the screw. According to the specific reason, step by step.
4, there is a sound inside the crusher: the components of the crusher are damaged, fall off or hard, such as stone and iron into the machine, that is, the external sound will be generated, and the machine should stop replacing damaged components or remove hard objects.
5. Low production efficiency: insufficient power of electric machine, misconduct, belt slip, severe hammer wear, high raw material unevenness or high water content is the main reason for the low production efficiency.
We need to regularly check the machines and equipment to ensure normal work, which not only guarantees the safety of people, but also improves equipment efficiency.
