In the classification operation of industrial production at this stage, the use of Fluidized Bed Jet Mill of Modified Silica is mainly for solid particles, and is a common use of more commonly used in the product ultrafine pulverization. equipment.
The crushing product is in addition to the particle size, and the particle size distribution is narrow, the particle name is smooth, the particle shape is high, and the high activity is high, the dispersibility is good.
Fluidized Bed Jet Mill OF MODIFIED SILICA Principle and Features: When the compressed gas enters the pulverizer through the feeder, the pulverized raw material enters the pulverizer, there are multiple pulverized nozzles in the pulverizing chamber, and the supersonic air flow is injected, so that the material is affected by the gas stream. High-speed shock and material collision, friction, and pulverized, the grading tube separates the thicker particles, the crude particles are circulated to the pulverizing chamber to continue pulverizing, after the interior closed circuit circulation is pulverized, and finally the distribution of uniform dispensing in the discharge port. . 1. Suitable for dry ultrafoil. Due to the large impact speed, it can reach 2.5 Mach or more. It is easy to obtain 1-10 micron particles, depending on the material properties, 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 are constantly pulverizing, and therefore the particles are uniform, small particle size distribution ranges are obtained. 3, the device has short-striped time, simple structure, convenient operation, small area, low noise (72 decibel) and no vibration. 4, the efficiency of the pulverization is high, which can be pulverized, and the purity of the pulverized article can be maintained.
Now let's talk about the exclusion of Fluidized Bed Jet Mill of Modified Silica common faults.
Fluidized Silica Troubleshooting:
1 Severe, etc. 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 breathability, 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 spindle, balance the rotor and adjust the belt, the bearing can return to normal state.
3, the strong vibration of the airflow pulverizer: The mounting 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,Will produce foreign sounds, the machine should immediately stop replacing damaged components or remove hard objects.
5, low production efficiency: insufficient electric power power, misconduct, belt slip, severe hammer wear, raw material unevenness or high raw material moisture content is the main reason for the low production efficiency.
We need to regularly check the machines and equipment to ensure proper work, which not only guarantees the safety of people, but also improves equipment efficiency.
