How We Do It?
Procemex Process
Step 1

The Procemex® Pulp Dirt Count Analyzer is an online measurement system. Dirt detector classifies pulp dirt and shives according to ISO and TAPPI standards providing both dirt count per square meter and dirt area per square meter (ppm).

Dirt that does not qualify a dirt according to the standard is rejected from the calculation. Beyond standards, some objects like metal wires, oil and special particles relating to different raw materials are detected and classified based on their shape.


Step 2

The Procemex® Dirt Count Analyzer is measuring in transmission with strobe LED lights with the camera resolution of 0.1 x 0.1 mm to meet TAPPI/ISO standards. You can choose between full CD/MD coverage or one camera per bale or just few measurement points. 

Step 3

The Procemex® Dirt Count Analyzer detects dirt in real time and stores every defect individually into the system database. The dirt detector keeps operators up to date with the amount of defect per set, per bale and per time. The amount of dirt in each bale is indicated both in real time values and with color coding. Operators can monitor real time dirt count trends indicating process changes and enable fast corrective reaction.

Step 4

The dirt detector values are transferred to the customer quality data management and bale tracking systems providing an easy access to any of the historical information.


Case Story of Dirt Count Analyzer in a Pulp Mill
The Starting Point

The customer had an existing dirt detector system. The 'black box' type of a system provided a dirt count number from one measurement spot.

Their current system was getting old, and there were issues with support and spare part availability. They wanted a modern online Dirt Count Analyzer with a classification function that complies with the ISO-5350-2 specification.

Procemex Solution - Dirt Count Analyzer
  • Provided a system based on Procemex 2.1 Mpix smart cameras and strobe LED light technology (Procemex One Platform Solution)
  • Same type of cameras and lights were already in use on one paper machine at the mill.
  • Procemex strobe LED lights easily penetrated the hardwood pulp and produced crystal clear and extremely detailed images and measurement.
  • Procemex® Dirt Count Analyzer measures 3 out of 7 bales.  As the measurement frame reaches already across the machine, it is easy to add cameras and measure all bales later on – if needed.
  • Dirt count data transferred to the mill quality system
