CDM at the Paper Mill

Posted on Wednesday, 16 March 2022 at 11:41

At the paper mill in Canada, the customer wants to measure and control the density of lime mud before the rotary kiln. The customer was always using radiation-based density meters in the past but wanted to look for sustainable alternatives. They decided to start a trial with the Rhosonics non-nuclear Chemical Density Meter (CDM) for one month.

The density is a critical parameter at this point of the process, because when correctly managed, it could prevent maintenance and downtime due to material that is sticking inside the rotary kiln. The customer wants to keep the density at a steady point, which means not too high or too low, close to the target value.

After a month of testing the customer was very satisfied with the density measurements of the Rhosonics CDM. In comparison with the nuclear density meter, the CDM provides more than density – the customer is also using a second analogue output for the measured suspended solid content.

Some of the benefits of using the CDM:

• Real-time in-line solids and density monitoring
• Wide range of measuring parameters
• The advantages of non-nuclear technology such as:
✓ No license needed
✓ No radiation safety officer (RSO)
✓ No administrative paperwork
✓ No area restrictions or limited access
