In practice, we find that many customers need to crush thermosensitive materials and plastics. These two kinds of materials are the difficulty of crushing industry, especially the experimental analysis, which is almost blank. After frequent communication and experiments with Taiwan, the problem was finally solved by the way of "liquid nitrogen tank cooperating with FDV crusher". Because the steel material used in this machine is excellent, the liquid nitrogen at low temperature is completely acceptable, so that the problem can be solved by adding liquid nitrogen while feeding. Thus, the application range of the machine is greatly expanded. For ordinary plastics, it can be crushed to about 60-120 meshes.
Practical operation skills of cryogenic ultrafine grinder:
Here are some very useful tips for FDV air-driven crusher. When feeding, Zui is good to throw on the center screw of the blade, which is helpful for the material to disperse rapidly and averagely to the surrounding area, making crushing fast and fine; feeding speed should be less and fast, i.e. fewer feeding points at a time but faster frequency, in a word, it is faster and less equipment than other methods; this machine is equipped with three types of blades, if Reasonable application can also achieve twice the result with half the effort. If the material is comparable to the crushing, such as chemical synthesis, crushing foot of Chinese medicinal materials, can use a large bender; material has a certain viscous choice of large bender, but the fineness of large bender crushing is not as good as straight knife; if the effect of straight knife crushing is not good, choose medium bender, fineness is higher.
Notices for the Superfine Crusher of Traditional Chinese Medicine
Notices for ultra-fine crusher of traditional Chinese medicine:
1. The input amount of crushing material should not exceed 1/2 of the capacity of crushing bowl.
2. Dry materials are crushed finer. Not suitable for processing wet and greasy articles
3. When the machine is just started, if the blade is stuck in the crushed material, so that the motor can not work properly, the power supply should be switched off immediately to avoid motor damage, and then work again after liquidation.
4. It takes only 1 minute to comminute ordinary Chinese medicines, and the time for special needs is longer. The crushing time should not be too long, so as to avoid the heat of fine crushing and sticking to the crushing bowl.
5. The ultra-fine crusher of this traditional Chinese medicine can not work continuously for a long time. It should not exceed 5 minutes at a time. When the processing quantity is large, it must rest in the middle to avoid motor damage caused by overheating of motor bearings.
6. When using for a long time, the wear level of carbon brush and blade should be checked normally. Replacement of accessories as appropriate
7. To avoid the machine falling to the ground and damaging the machine, a relatively stable worktable should be installed.
8. If it is found that the motor is not working properly, check the circuit or check the fuse
9. Don't turn on the top cover of the ultra-fine crusher of traditional Chinese medicine when it is turned over.
10. Warranty period is one year, life-long maintenance
