Belt grinder for board material

摘要

The belt grinding machine for chipboard and fibreboard materials, containing lignocellulose and/or cellulose, has at least one pair of grinders (6,7) over each other for the contact rollers (11), with grinding belts (12) moving against each other and against the advance direction (14) of the material (13) feed. The material is centrally within the symmetrical assembly. The final section of grinders (8,9) have pressure shoes (16) aligned across the material feed direction (14) for fine grinding with one shoe (16) of a relatively low elasticity using PTFE, hard or foam rubber, while the other shoe (16) has a relatively high elasticity using felt and/or foam rubber.
