The pre-cleaner was designed to protect the production installation against damage caused by foreign objects. Its ideal position is in the intake line for raw materials.
The Ottevanger pre-cleaner separates pieces of wood, stones, textiles, etc. from the material flow, namely items that can cause damage to transport and production equipment.
A special add-on, which has proven itself to be reliable, is available for removing threads, ropes, etc. from the raw-material flow.
Option: the pre-cleaner can be fitted with an additional extraction connection which removes finer items from the raw material.
