Patents Assigned to EQTEC Engineered Quartz Technology GmbH
  • Patent number: 11541569
    Abstract: The invention relates to a method and a plant for the continuous production of engineered stone slabs. In the method, raw materials comprising at least one mineral filler and one organic binder are mixed, applied to a lower belt of a dual-belt press, or a conveying means mounted upstream of the lower belt, and subsequently continuously pressed, and the binder is cured. A continuously-obtained material strand is separated into individual engineered stone slabs. It is provided that the mixing operation of the raw materials is carried out at staggered times in a batch mixing operation by means of at least two separate mixing devices. The mixed raw materials from the mixing devices are transferred into one, or multiple, spreading device(s) at staggered times and are applied continuously and without interruption to the lower belt, or the conveying means mounted upstream of the lower belt, by means of the spreading device(s).
