Jet Mill of Nimodipine is a clean, efficient, high-level, high-yield of advanced crusher models in the pulverization of Western medicine raw materials, and test from a few triggered trace experiments. The large production of hundreds of tons of production, the airflow mill is narrow by it: the particle size distribution is narrow, the average particle size is fine; the powder is good, the product is high; suitable for low melting point, thermal drugs; good sexy, less pollution; Easy; crushing - mixing - dry online operations, etc. have been widely recognized by the company.
Jet Mill of Nimodipine is mainly used for more refined materials. The graded 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 grading 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 feedstock is sent together with the airflow into a grading device. 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 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 gas 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 hierarchical chamber portion.
The Jet Mill of Nimodipine has the characteristics of high leveling range, high grading efficiency, high grading accuracy, accurate cut particle size, and good stability.
What is the grading principle and process of Jet Mill of Nimodipine? Below, belowEnjoy it.
2, the raw material enters the feeder
3, the raw material enters the feeder injector in the feeder
4, the raw material reaches the hierarchical body after special dispersion, grading through physical effects such as airflow and gravity;
5, the airflow of the three flow paths has the control valve group adjustment to maintain their respective balance;
6, grading The rear coarse fine product is recovered separately;
7, clean air is discharged into the atmosphere.
Jet Mill of Nimodipine's daily maintenance
1, during the production process, the temperature rise of the bearing must be checked, and when the temperature rise exceeds 50 ° C, it should be closed, and the reason is to rule out the fault.
3, if the loss case should be checked frequently, replace the quality and production volume in time.
4, the blade, the bushing should often check the wear situation. If the wear is worn, the productivity is lowered, and the particle size is replaced after the particle size is replaced.
5, the host and the graded flow bearing are lipids, and the No. 2 special lipids are used 265-295.
6, the replacement period of the bearing is 2000 hours, and the amount of the grease is filling the amount of the space in the bearing cavity (episode) or 3/4 (lower test) cut, not too much to fill the grease, otherwise The bearing temperature is too high.
7. The spiral feeder has been changed during the change of the lipid of 4,000 hours, and the calcium-based grease is added.
