The cosmetics contain a large amount of solid powder, such as titanium powder, calcium carbonate, gas flow wear technology to manufacture high-grade pressure powder makeup manufacturing, can improve powder structure, greatly improve the performance of powder performance and product quality.Large airflow pulverizer is usually common equipment for each processing enterprise, due to its large production, high efficiency, especially suitable for a large amount of processing of various powders. However, the problems faced by the large airflow pulverizer will also be more, because it is a large amount of production for a long time, what is the cause of the pulverization process, leading to this phenomenon? Let's take a look along with Xiaobian.
Cause 1: The fineness of the powder material is small, the particles are fine, such as the case of 10-20 microns or more, and the powder material The fluidity is poor, causing the feeder to stabilize the continuous feed, thereby affecting the pulverization efficiency and pulverizing particle size, such as 5 kg of the feed speed, may be 3 kg after 1-2 hours, 2 Kg, 1 kg, then gradually slowing down, no more, this requires designing the feeding system to ensure that a batch of materials can be smoothly pulverized.
Cause 2: Wenqi 里 料, this is the problem that the powder material is often encountered, as the solvent and impurities affect the process of spraying the material to the pulverization plate through the venturi Slowly connect a film on the foliage hole, then the film level is thicker until it is blocked in the wall of Wenqi.
Cause 3: Cruminating dispersion Clogging cannot be produced.
Cause 4: The dust collector structure of some companies is to collect materials in a manner that uses air blowers and pulses. This structure can cause the material to enter the bottom of the vertebral body after the material into the bottom vertebral body. Walk, affect the pulverization process.
So, when the large airflow pulverizer is selected, ZUI is better as the following steps:
1. To perform material test, the purpose of test is to see the particle size;
2. To see the operability of the device, try to make it clear;
3.The difficulty of cleaning is difficult, there is no dead end;
4. Look at the collection rate of materials;
5. Check out what problems occur during the pulverization process, do experiment The more problems found, the better so that the equipment to purchase will be more necessary in the future;
6. Look at the feed pressure and smash pressure of the pulverization plate, currently the feed pressure of most manufacturers Big than the crushing pressure, the main reason is that it is afraid of blowing, but the crushing pressure is very crushed, so try to choose a large pulverization pressure, small feeding pressure, large particle size distribution of large particle size;
7. Select only one device that collects the mouth, there is currently a number of devices due to technical capabilities, in two positions of the material need to collect materials, which will cause problems with the homogeneity of materials, and the pulverization will also put The two materials are mixed, increase the link, so the device to choose only one collecting mouth;
8. The feed should not use pulse to blow dust, which will affect the distribution of the particle size;
9. Consider the feed mode of the material, some feeding mode is one of the nozzles of the pulverizing disk nozzle, the diameter of this nozzle is more than other nozzles, so the ability is greater than other nozzles, resulting in a powder into pulverization The position of the disc is closer to the outlet, resulting in the appearance of large particles and the poor particle size distribution.
Shandong Erfai production of large airflow pulverization can effectively prevent blocking phenomena, and can formulate different solutions according to different materials, and ensure smooth users, more information about gas flow crushers, continue to pay attention to Shandong El Pie.
Shandong ALPA Powder Technology has always firmly convinced that the basis of the global brand is the improvement of product and service quality, and behind the quality of the quality is a fear of market. Under the line, from a single channel to multi-dimensional propagation, from China to overseas, Shandong AlPa powder technology has always been combined with dealers, the user's demand is centered, and the quality improvement is based on the construction of globalization. The powder equipment brand is a vision, continuously striding forward, and has achieved a new breakthrough, and a strong "Chinese voice" in the industrial powder equipment field.
