Customers often ask about the longevity and durability of our granulation machinery. Moreover, two common question are, “What is the wearing part?” or “How long does it take to replace the mold?”

What is the wearing part?

Firstly, let’s understand what worn parts refer to. In Shunxin’s roller granulator, the worn parts are the roller sheets. For one thing, two rollers are made of special alloy materials to endure high pressure and wear during the dry granulation process. For another thing, you don’t need to worry about the replacement of two rollers. If you normally use and maintain double rollers pressing granulator according to the operating instructions, the service life of 2 rollers can reach at least 6 months. However, when you find that the roller is worn or the granulation quality is getting worse, you should consider replacing it with a fresh roller.

How long does it take to replace the mold?

Secondly, you should know the time for replacing the mold. Overall, in most cases, you may need to replace the rollers within 6 months to 1 year. Furthermore, many elements will impact the particular time, including frequency of usage, raw materials’ kind and quality, and so on. To guarantee the performance of the rollers and the efficient operation of this granulator, we recommend that you regularly inspect and perform necessary maintenance. If you see that the roller is worn out or that the granulation effect is poor, it is time to replace it.
