Getting ready for the grinder season: Colourizer Tips
As spring approaches and temperatures begin to warm up again, many companies that convert wood waste into valuable mulch are both excited and eager to thaw out their grinding and colourizing 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.
First, be sure to thoroughly clean all colourizer lines. This can be done by simply running water through the lines to ensure any dirt, debris or containments are cleared out.
Next, inspect injection lines at the top of the grinding chamber to make sure they are not restricted. Even a small amount of buildup in this area should be cleaned and removed to ensure the process is as efficient as possible.
Check the water supply and the water lines. Make sure they are clear, clean and that all connections are fitted correctly. Also check the colour pump lubricant level to ensure a sufficient amount is present in the pump.
Finally, be sure to test the colourizer system before starting, especially if you're starting the colour pump for the first time after the winter. Testing can be done by simply running a five-gallon bucket of water through the system to ensure all components are working properly.
As mulch producers navigate through the spring months when weather can continue to be unpredictable, and especially as temperatures can dip back below freezing, a few additional helpful tips are listed below.
If you are operating in temperatures that are below freezing, it is important to drain the colourizer system after use to prevent any liquids from freezing within the colourizer or water lines in the system.
Also, do not use frozen colourant. Using frozen colourant can lead to unequally mixed colours and damage and obstructions to the colourizer lines.
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 steps, something is not working property or your output is not providing the results you need, contact your equipment's customer support team to assist with any questions.
