The Hallsta Paper Mill, a part of Holmen Paper business area, is located about 100 kilometres north of Stockholm. The mill has two paper machines producing TMP based paper for various end-use segments, e.g. books and magazines.

“The Hallsta Paper Mill has a long history with PulpEye and they bought their first equipment already in 2006,” says Öjvind Sundvall, MD of PulpEye. “Now three analysers are placed in the TMP plant and since 2009 there is one in the paper mill, analysing samples from both paper machines’ stock preparations. The fifth is placed in the laboratory and will be used as a master for all online pulp analysers in the mill.”

“Our existing pulp analysers had for many years served us well but they were gradually approaching the end of their lifetime,” says Maria McGuinness, Production Engineer, TMP and Bleaching, at Hallsta paper mill “A couple of years ago we therefore evaluated the different future replacement alternatives. We wanted a robust technology combined with flexible usage as well as good service and support and concluded that PulpEye was the pulp analyser most suitable for our needs. We have just received our fifth PulpEye in the mill. So now we have a modern and efficient way of controlling the pulp and stock quality.” 

The PulpEyes in the TMP department are used to control the refiners such as quality control of the pulp as well as of the reject handling. The one in the stock preparation is used to control the LC refining processes. All PulpEye analysers are equipped with fibre, shives and CSF modules and in addition one analyser in the TMP department is also equipped with a CrillEye to analyse the pulps from the TMP plant for the paper machines.
