The invention relates to a device and a method having a first and a second zone (Z, Z) for producing insulating or acoustic panels from a pressed material mat () which consists at least partially of lignocellulose particles coated with binders, the first zone (Z) being designed for heating and/or compressing the pressed material mat, and the second zone (Z) being designed for curing the pressed material mat with the aid of calibration plates (), and there being driven circulating screen bands (-) in contact with the upper and lower pressed material mat surfaces. According to the invention, to increase the production speed, at least four circulating screen bands (-) are used, at least two of which are in operative contact with the pressed material mat () in the region of the first zone (Z), and at least two of which are in operative contact with the pressed material mat () in the region of the second zone (Z).

Method and apparatus for making insulating panels

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.

Method of glue-coating plant particles

The invention relates to a device and a method for separating and/or recovering silicate particles from plant material. This device and the method are characterized by an air classifier (), which has at least one material inlet (), an air inlet (), arranged under the material inlet (), an air outlet () and at least one particle receptacle (), arranged under the air outlet, wherein the plant particles recovered from plant material by crushing can be subjected to an air stream in the air classifier () in such a way that silicate particles contained in the plant material are removed by the air stream via the air outlet () and, as a result of gravitational force, the plant particles are received by the particle receptacle () arranged under the air outlet () and taken away.
