Abstract
Fiberboard or chipboard is made by first comminuting vegetable starting material in a first comminutor into a stream of loose plant particles with silicate particles. Then, in a first classifier silicate particles of a diameter of less than 50 μm are separated from the plant particles of the stream. The plant particles remaining in the stream are then glue-coated, and the stream is pressed into fiberboard or chipboard.
Claims13
A method of making fiberboard or chipboard, the method comprising the steps of:
- comminuting vegetable starting material in a first comminutor into loose plant particles and silicate particles;
- in a first classifier air separating silicate particles of a diameter of less than 50 μm from the plant particles;
- glue-coating the remaining plant particles;
- and
- compressing the glue-coated plant particles into fiberboard or chipboard.
