Daily maintenance of jet mill

Daily maintenance of jet mill
After paying a large price for the jet mill, users often only pay attention to the use effect of the product, but they don’t know much about the maintenance of the jet mill, so some problems arise during the operation, which makes the air flow The shredder cannot play a great value in the process of use. The following are some aspects that need attention in the daily maintenance of the jet mill summarized by the Weifang Essence Powder Technology Department. I hope it will be helpful to everyone!
The working principle of the jet mill is that after the compressed air is cooled, filtered and dried, the Laval nozzle forms a supersonic jet into the grinding chamber to fluidize the material. The accelerated material merges at the intersection of several nozzles, resulting in violent The collision, friction, and shearing of the particles form ultra-fine crushing of particles. Especially for solid impact, it has a very targeted effect. According to the current smashing situation, combined with the implementation of different standards, it is possible to achieve a more ideal degree in different types or corresponding relationships. The impact effect of the jet mill is more in line with the current operating trajectory and advantages. At the same time, it is necessary to strengthen the maintenance and self-protection of the equipment. After all, the loss caused by the equipment failure is immeasurable.
The following are the points that need attention in the daily maintenance of the jet mill:
1. During the production process, the temperature rise of the bearing must be checked frequently. When the temperature rise exceeds 50°C, the machine should be shut down for inspection to find out the cause and eliminate the fault.
2. When the new machine is running, the drive belt is easy to stretch, so attention should be paid to adjusting the belt's proper tightness to ensure the belt's working life.
3. The wearing parts should be checked frequently and replaced in time to ensure production quality and throughput.
4. The blades and bushings should be inspected frequently for wear. If they are worn, the productivity will decrease, and the grain size will become coarser, and they will be replaced when they are worn.
5. The main engine and grading flow bearings are all grease lubricated, using No. 2 special grease, degree 265-295.
6. The grease change period of the bearing is 2000 hours, and the filling amount of grease is 1/2 (upper measurement) or 3/4 (lower measurement) of the space in the bearing cavity. Do not fill with grease too much, otherwise it will cause bearing temperature Too high.
7. The grease change period of the screw feeder is 4000 hours, plus ordinary calcium-based grease.
The reason why the jet mill can have such a wide range of uses is that it can achieve a more ideal use standard. According to the overall stable situation, stable effects can still be achieved in areas that can be effectively improved. According to the advantages of overall execution, as long as it conforms to the development trajectory, after all, it is mainly to deal with the impact of fierce market competition. we want
Regular maintenance to ensure its working efficiency can extend its service life. Enterprises are producing jet mills, don't let them work excessively, distribute them reasonably!
