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.

Disclosed is a tea leaf and tea stem separating device. The tea leaf and tea stem separating device comprises a machine shell, wherein a collecting mechanism, a peeling mechanism, a separating mechanism, a rocker mechanism and recycling mechanisms are sequentially arranged on the machine shell in the falling direction of materials, a driving mechanism is arranged at the position, corresponding to the separating mechanism, of the inner wall of the machine shell, the driving mechanism is provided with a conveyor belt mechanism connected with the peeling mechanism, the separating mechanism and the rocker mechanism, and the driving mechanism can drive the conveyor belt mechanism to move so as to pull the peeling mechanism, the separating mechanism and the rocker mechanism to synchronously reciprocate.
