Modern production is not only the pursuit of production and product quality, but also in the direction toward eco-friendly development. Especially in the crushing industry, look at the requirements of modern social productive forces, the overall trend Ultra-micro Steam Jet Mill grinder technology in China is toward rate, control, and stable development of high quality and so on.
What factors will affect the performance parameters Ultra-micro Steam Jet Mill grinder use it?
The following is a detailed description:
1 Control feed size
Most Ultra-micro steam jet mill grinder to feed size limit certain requirements. After entering the pulverization chamber, the material can be sufficiently accelerated before collision and crushing with other particles. After large particles enter the pulverized cavity, it is difficult to completely accelerate, which will make them live too long in the machine, resulting in too high energy consumption. Therefore, in large-scale production of ultrafine powder, it is an effective way to prepare a raw material having a large particle size is an effective pathway for energy saving.
2. Working medium
Currently, Ultra-micro steam jet mill grinder main working medium is compressed air, superheated steam, inert gas. The choice of working fluid has a certain impact on crushing effects and economics. Superheated steam is better than air in terms of fluidity and critical flow rates, achieving higher flow rates and uniform flow fields. However, using superheated steam as a working fluid, it must be ensured that it is still in an overheating state before entering the product capture device, otherwise the material is condensed.
3. Feeding speed
Feeding speed is an important parameter reflecting gas flow grinding production capacity. During the pulverization process, the optimum ratio of the intake flow rate and the feed speed is the key to improving the crushing efficiency. In general, in a certain intake flow conditions, the feed speed is proportional to the product particle size. However, the feeding speed is too fast, which will increase the particle density, mutual interference of the pulverization zone, which is not conducive to the acceleration of the particles, it is difficult to achieve a sufficiently effective collision between particles, affect the crushing effect; although the feed speed is too slow, the particles stay in the crush area The time can be extended, which will reduce the particle density, reduce the collision rate, resulting in a decrease in production capacity and an increase in unit production energy consumption.
4. size limit
Ultra-micro steam jet mill grinder in the grinding process, the material with decreasing particle size, uniformity and intensity crystalline material is increased. After reaching a certain degree, the particle size of the material is no longer reduced or decreased slowly, that is, the crush limit of the material is reached. At this time, the surface area of \u200b\u200bthe material increases, the surface activity of the particles is increased, and the particle agglomeration and grinding are in a dynamic equilibrium state, even if the grinding time is prolonged, it is difficult to further reduce the particle size of the material.
in the production process, the bearing temperature should always check, when heating, beyond 50 ℃, should stop to check, is to identify the reasons and troubleshooting. When the new machine is running, the transmission belt is easy to elongate, pay attention to adjust the appropriate looseness of the belt to ensure the work life of the belt. If you want to check, you should replace production quality and production in time. Blades, the lining should often check the wear situation. If the wear is worn, the productivity decreases, and the particle size is replaced after the particle size is replaced. The host and the grading flow bearing are lipids, and the 2nd special lipid is used. The replacement period of the bearing is around three months, and the filling of the grease is 1/2 of the outer space space in the bearing cavity. Do not fill the grease. Otherwise It will cause too high of the bearing temperature. The spiral feeder has changed the lime than half a year, and the calcium-based grease is added. In the output shaft E, ie the pulley E, avoiding heavy hammer, damage the part. It is strictly forbidden to turn the handle on the stop. The lubricating oil used in this regulator is used with N32 alkaline high-z7-degree anti-motor oil pressure oil, and the deceleration machine is used 401 generally lubricating oil, and it is not necessary to use other machines. After four or five months, new oil should be replaced.
El pie chicken protein Ultra-micro steam jet mill grinder Case Study: The company is a Spanish company, which needs to smash one kind of chicken protein, we asked all over Europe several powder equipment companies are without the right equipment. Later, I learned that our El Pie, the testism sent us a message, and we didn't determine if the material could not be done after receiving the email. But our El Pie or decided to try it, then let the customer mailing material will be experimentally. Through multiple experiments, we have identified a crushing equipment that meets the particle size requirements of the company. Finally, the company also purchases the series of equipment.
Technical parameters:
Finished size: 100μm
production capacity: 500KG
