In the hammer crusher equipment, where abrasive wear and fatigue wear all kinds of wear and tear are the most serious kind of situation, 50 percent of the exhibition area of the metal, but also the prevalence of the problem of broken machine equipment, reduce hammer crusher There are several wear rates in the machine work: 1. Because the journals at both ends of the spindle are easy to wear during operation, we add two bushings at the journal to protect the journals during installation. 2. Under normal circumstances, the edge hammer of the hammer frame and the side plates of the casing are worn more seriously. At this time, we can weld the wear layer around the circle of the side plate and on one side of the side plate. 3. When operating the hammer crusher equipment, it is necessary to evenly add the crushed material and distribute it over the entire length of the working part of the rotor to avoid an increase in the load of the motor. 4. Regularly check the condition of the screen. If there is any blockage, it should be cleared immediately. 5. The hammer crusher bearing is under normal working, the temperature is kept within 35 degrees, and must not exceed 70 degrees. There are many kinds of materials for preparing microspheres, which are mainly divided into natural polymer microspheres and synthetic polymer microspheres. The compatibility of microspheres is a very important aspect, including biocompatibility, which usually depends on the material from which the microsphere is prepared, and geometric compatibility, which is related to the roundness of the microsphere. There is no precise limit on the diameter of microspheres, which can generally be divided into nanospheres and microspheres. Nanoscale microspheres are also commonly referred to as nanospheres. bio based medical microspheres Ningbo Neon Lion Technology Co., Ltd. , https://www.neonliontech.com
