Abstract
A method and an apparatus for reducing the moisture content bound by capillary action in fiber cells. To include fine material economically and easily in the process, coarse material is sandwiched on top of fine material and then pressed and dried. The material prepared by grinding and screening is transferred as coarse material to a first spreader hopper, and the screened fine material is transferred over a chute and conveyor belt to a second spreader hopper. The fine material is spread in a thin layer through a vertically adjustable gate from the second spreader hopper onto a spreading, loading and filtering belt, and the coarse material is withdrawn on a transfer conveyor belt running below the first spreader hopper and then is spread through a vertically adjustable gate onto the fine layer, to form a sandwich-like mat.
