Hammer Mills Of Plastic As the name refers to a mechanical equipment used in the production area, which is mostly used in pulverizing particles, fast pulverity, good accuracy.
Which factors affect Hammer Mills of Plastic Performance parameters?
The following is a detailed description:
1. Feeding granularity control
Most Hammer Mills of Plastic has a certain upper limit requirement for 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 Hammer Mills of Plastic 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
Hammer Mills of plastic In the pulverization process, as the material particle size is reduced, the crystallization and intensity 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 material specific surface area increases, the surface activity of the particles, 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.

Hemler Mills of plastic daily maintenance
1, during production, Check the temperature rise of the bearing, when the temperature rise exceeds 50 ° C, 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.
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.
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.
