Method for the production of solid surfaces for construction

A method for the production of a board made from materials for construction comprising the following steps:

• a) storing raw materials that are inorganic,
• b) controlled metering different ones of the raw materials,
• c) dry milling or wet milling the raw materials from the controlled metering of step b) to obtain a first mixture,
• d) storing the first mixture obtained in step c),
• e) processing and adding color pigments to a proportion of the first mixture stored in d), obtaining a first colored mixture,
• f) mixing at least some of the first mixture with the first colored mixture obtained in step e) to obtain a homogenous colored mixture,
• g) storing different homogenous colored mixtures obtained from steps a) through f) using different color pigments,
• h) creating a blanket of different homogenous colored mixtures by metering the different homogenous colored mixtures on a conveyor belt to create different embellishments throughout an entire volume of the blanket or throughout at least a portion of an entire volume or a surface of the blanket in a non-homogenous manner, wherein the application of different embellishments comprises controlled distribution onto a conveyor of the different homogenous colored mixtures in order to obtain a desired aesthetic design,
• i) subsequent to step h), compacting the different homogenous colored mixtures at a compaction pressure to form a compacted board,
• j) sizing an end part of each compacted board by cutting through an entire thickness of the compacted board,
• k) pressing the compacted board at a pressure greater than the compaction pressure to form the board for construction,
• l) drying the pressed board,
• m) subsequent to drying the pressed board, cooking the pressed board, and
• n) calibrating, polishing, cutting or beveling edges of the cooked pressed board.
