<p>The method for continuously obtaining compact sheets (L; L1) with materials arranged in a particulate state mixed with a binder constituted by hydraulic powder of a quick-setting cement comprises the steps of: moistening the particles with a humidifying liquid in a quantity according to a pre-established ratio by weight; coating said particulate materials with a film of said quick- setting powder binder; stratifying, with meter means (1), the dried and coated particles onto a movable belt (2) in a substantially uniform layer (S1); transferring the particles from said meter means (1) onto a further belt (3), nebulizing said humidifying liquid on the same particles during the transfer, without washing away said film; repeating said transfer onto further belts (4, 5) until a pre-established quantity of humidifying hydration liquid is supplied, obtaining a hydrated mixture; transferring the hydrated mixture onto a final conveyor belt (7), forming a mixture layer (M) of said particulate materials; adjusting the speed of such final belt (7) with respect to said further belts (4, 5) as a function of the thickness of said mixture layer (M) to be obtained; introducing said final belt (7) and mixture layer (M) into continuous press means (PC) equipped with a size adjustable inlet at least with regard to height, obtaining a continuous, height-calibrated sheet (LC); and cutting the hardened, continuous sheet (LC) to size, obtaining cut sheets (L), and collecting said cut sheets (L) from said movable belt (7) with collection means.</p> |
