In many crushing methods, Pin Pulverizer of Hot Melt Glue has become one of the most mainstream pulverization techniques with a small particle size, narrow particle size distribution, high purity, high particulate activity, and good dispersibility. Especially suitable for crushing drugs such as contaminated materials.
What factors affect the performance parameters used by PIN Pulverizer of Hot Melt Glue?
The following is a detailed description:
1. Feed granular control
Most PIN Pulverizer of Hot Melt Glue has a certain upper limit requirement for the feed particle size. After entering the pulverization cavity, it can be sufficiently accelerated before collision and crushing with other particles. It is difficult to completely accelerate after large particles enter the pulverized cavity, which will allow them to stay in the machine too long, resulting in too high energy consumption. Therefore, in large-scale production of ultrafine powder, it is an effective way to pre-ground the raw material of the particle size is an effective pathway for energy saving.
2. Working medium
Currently, the working medium of PIN Pulverizer of Hot Melt Glue is mainly compressed, superheated steam, inert gas, and the like. The choice of working fluid has a certain impact on crushing effects and economics. Superheated steam is superior to air in fluidity and critical flow rates to achieve 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, under certain intake flow conditions, the feed speed is proportional to the particle size of the product. However, the feeding speed is too fast, which will increase the particle density, mutual interference, disadvantage of the particles, and difficult to achieve the sufficient and 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. Granular limit
Pin pulverizer of Hot Melt Glue In the pulverization process, as the material particle size is reduced, the crystallization and strength of the material increases. After reaching a certain degree, the particle size of the material is no longer reduced or reduced, that is, the crushing limit of the material is reached. At this time, the surface area of \u200b\u200bthe material is increased, and the surface activity of the particles increases, the particle agglomeration and grinding is in a dynamic equilibrium, even if the grinding time is prolonged, it is also veryIt is difficult to further reduce the particle size of the material.

Pin Pulverizer of Hot Melt Glue daily maintenance
1, during production, the temperature rise of the bearing must be checked When the temperature rise exceeds 50 ° C, it should be closed, and the reason is to rule out the fault.
2, when the new machine is running, the drive belt is easy to elongate, and should pay attention to adjust the appropriate looseness of the belt to ensure the work life of the belt.
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.
