What is the working principle of a rotary granulator machine?

If you know how a rotary granulating machine works, you will have a better understanding of this granulator. The following is the specific working principle of rotary drums.

First of all, the main motor of the rotating drum granulator drives the belt and the belt pulley to move.

Then, through reduction drive, the main driving shaft starts driving the drum part to rotate. The raw materials enter into the rotary drum at the feed end.

In the rotary drum granulator, the raw materials get pelletized through the function of the special internal structure.

Next, the finished pellet fertilizer will come out of the rotary granulating machine at the discharge port. The whole granulating process lasts for 3~5 minutes, which means Tongda rotary drums can produce pellet fertilizer fast.

In addition, Tongda rotary drums can achieve continuous volume-produce. You can gain more earnings with large output.

The granulation rate of rotary granulators is about 90%. Honestly speaking, the granulation rate is pretty high. However, in order to maximum your profits, we suggests that you take some measures to improve the granulation rate.

How to improve the granulation rate of rotary drum granulators?

Make sure that you have high-quality and reasonable formulas

The temperature and moisture content of the raw material are two important factors that can influence the pelletizing effectiveness. Therefore, if you want to improve the granulation rate of your rotary granulator, you must have accurate and high-quality formulas for making pellet fertilizer. On the basis of well-balanced raw material, you can continuously optimize your formula according to the traits of your rotary drum. By doing so, your rotary drum fertilizer machine will become more efficient.

Choose a superior rotating granulator

The rotating speed and the internal structure of the rotary fertilizer making equipment can influence the granulating effectiveness greatly. Therefore, you can choose a well-designed rotary drum granulator for better granulating effectiveness. Tongda rotary granulating equipment would like to be your best choice. With rotation of the rotary drum, the raw material is mixed evenly in the rotary granulator. What’s more, you can adjust the rotating speed of Tongda rotary drum according to feeding amount of the raw material.

High-quality rotary drums can guarantee a high granulation rate, but you also need to maintain high-quality rotary granulators. If you do a good work to maintain it, you can make use of your rotary drum for a longer time.

  • The newly installed big gear wheel might be loose, you should check this part carefully;
  • To observe if all the parts of the rotary drum are working well;
  • You should inspect the attrition rate of your rotary drum, because there are some quick-wear parts of it. If any part of the rotary drum needs to be changed, you should replace it with an alternative timely;
  • You should place the rotary drum should on flat ground;
  • If the temperature of the bearing rises, you should halt the granulator machine and uncover the reason;
  • When the big gear wheel start to work, if there is any impact sound, you should halt the rotary drum and inspect it.
