These devices are used for Grenoble INP - Pagora, UGA teaching activity and as pilots regarding LGP2 research work.
They can be accessed for industrial trials.
Fourdrinier paper machine
Operating conditions are fare from actual paper machine ones but anyhow, making trials can be a good step between laboratory and production.
Examples: testing a new fiber composition, working on retention agent or additives... The paper machine can be adapted to use new equipements.
Production capacity : 100 kg/hr
Head box width : 1 m
Basis weight from 20 to 400 g/m²
Production speed: from 5 to 30(50) m/mn
ALLIMAND type head box and distributor
Vacuum boxes and vacuum cylinder
Sampling and injection possible all along the wet section
2 press sections with hard and soft roller
Press on {A side + A side} OR {A side + B side}
Drying section with 5 steam cylinders (3Bar max) disposed on 3 sections (1+2, 3+4, 5)
Drying on A side (section 1 & 2), drying on B side (section 3)
Cylinders 1 to 4 covered with Teflon film
Pope type rolling section
7 DC drives control
Centralized control loops and measuremen (ABB system).

Refining pilot
The study of the characteristics development of a certain type of fiber can be easily performed on the pilot with a low amount of pulp and in replicable conditions to those industrial systems. Its small size also allows to validate low-cost new geometries and new discs materials.
