8 Tips to Get your Colorizing System Ready for Mulch Season

As spring approaches and temperatures begin to warm up again, many companies are both excited and eager to thaw out their grinding and colorizing equipment and get started as quickly as possible.

Before the work begins, though, taking a few preventative steps to ensure equipment is prepared for the season will provide the best opportunity for success and profitable results.

  1. First, be sure to thoroughly clean all colorizer lines. This can be done by simply running water through the lines to ensure any dirt, debris, or contaminants are cleared out of the lines.
  2. Next, inspect injection lines at the top of the grinding chamber to make sure they are not restricted. Even a small amount of build up in this area should be cleaned and removed to ensure the process is as efficient as possible.
  3. Check the water supply and the water lines. Make sure they are clear, clean and that all connections are fitted correctly.
  4. Next, check the color pump lubricant level to ensure a sufficient amount is present in the pump.
  5. Finally, be sure to test the colorizer system before starting, especially if you’re starting the color pump for the first time after the winter. Testing can be done by simply running a 5-gallon bucket of water through the system to ensure all components are working properly.

As you navigate through the spring months when the weather can continue to be unpredictable, and especially as temperatures can dip back below freezing, a few additional helpful tips:

  1. If you are operating in temperatures that are below freezing, it is important to drain the colorizer system after use to prevent any liquids from freezing within the colorizer or water lines in the system.
  2. Also, do not use frozen colorant. Using frozen colorant can lead to unequally mixed colors and damage and obstructions to the colorizer lines.
  3. Lastly, be sure you are utilizing the correct screen sizes. If the feedstock you are using is wet, utilizing larger screens will prevent clogging up the machine and slowing down the process.

If after following these start up steps, something is not working properly or your output is not providing the results you need, contact Rotochopper customer service to assist with any questions.
