Valmet to Deliver Bale Tester to Papresa’s Paper Mill 

Valmet is to deliver a Bale Tester to Papresa’s paper mill in Errentería, Spain. Valmet Bale Tester is a reliable and real-time measuring system for recovered paper, providing an opportunity to reduce operational costs and to improve the recycled fibre line performance.

The order was included in Valmet’s orders received in the first quarter 2024. The value of the order will not be disclosed. The scheduled delivery period will be during the fourth quarter of 2024.

Papresa is currently lacking a reliable system to control the quality of recovered paper delivered to the mill. Valmet Bale Tester measures the moisture and other contaminants, such as plastic and ash of the recovered paper. The information is automatically stored in the mill’s database, analysed, and further utilised for optimising the production process.

We are really looking forward to getting the Valmet Bale Tester installed. We believe that the real-time measurement system will improve the quality of recovered paper delivered to us, leading to decrease in operational costs and enhanced end-product quality.

“Valmet Bale Tester has been on the market for over 20 years and has a large, global installed base. Based on the vast number of references, it is expected that Papresa will see raw material quality increase, meaning a fast payback for the investment,” said Alvaro Echevarria, Senior Mill Sales Manager at Valmet.

Delivery’s technical information
Valmet’s delivery will include the installation of Valmet Bale Tester On-truck solution, extended with ash and lignin sensors and related software, the system’s start-up and a spare parts package. The On-truck model measures the raw material samples directly from the bale onboard the truck.
