What are the reasons why the spindle of jet mill is easy to be damaged?
Jet mill, as one of the main equipment for ultrafine grinding, is widely used in ultrafine grinding of non-metallic minerals and chemical raw materials. The particle size limit of the product depends on the solid content in the mixed gas stream and is directly proportional to the unit energy consumption. In addition to fine particle size, airflow grinding products also have the characteristics of narrow particle size distribution, smooth particle name, regular particle shape, high purity, high activity, and good dispersibility.
The jet mill has many core accessories, and these attachments are also fragile parts. If you do not pay attention to maintenance, it will cause serious consequences, especially the break of the jet mill spindle will cause downtime, and output loss cannot be estimated. The following section introduces the reasons for the breakage of the jet mill spindle.
Reasons for easy damage of jet grinding spindle:
1、Since jet mills need to pulverize and grind large ore for a long time, mechanical impact will cause fatigue damage to the spindle. If it is operated for a long time, the surface of the spindle will wear and cracks will occur if care is not taken.
2、Excessive air supply will cause the airflow machine to run overloaded. When the jet mill is used, it needs to be properly fed, and the workload of each machine is limited. If this limit is exceeded, parts are easily damaged during load operation, which will affect the overall service life of the jet mill.
3、In the process of mining and transportation, ore is often mixed with some scrap metals. When these objects pass through the electromagnet located on the upper part of the belt, due to the weak adsorption capacity of the electromagnet and the metallic characteristics of the manganese steel material, the electromagnet cannot be eliminated, resulting in These materials are incorporated into the jet mill in the ore and mud, causing frequent impacts on the main shaft and other parts.
In view of the above reasons, when we use the jet mill, if we want to use it for a longer time, try to ensure that its workload is within the range that the machine can withstand, and at the same time pay attention to its maintenance work, a good maintenance work Can also better help use the machine.
