Method and device for producing engineered stone slabs

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).

ALUMINA CERAMIC INTEGRATED HOT PRESS MOLDING MACHINE AND WORKING METHOD THEREOF

An alumina ceramic integrated hot press molding machine and working method thereof, including a pressing and hot pressing device fixed accordingly on a rack, a stirring device inside the hot pressing device, and a hot pressing mold above the hot pressing device; the pressing device enables one path of high-pressure air to act on the mold, and enables the other path to enter the hot pressing device, so the slurry flows into a cavity of the mold; the stirring device stirs the slurry inside the device, so alumina blanks are more evenly distributed therein; and temperature detection components for detecting the temperature of internal oil and the slurry at a slurry outlet are inside the hot pressing device, and the power of an electric heating device is adjusted and controlled in real time according to the temperature detected by the components, to achieve the purpose of accurate temperature control.

Casted block molding apparatus and method

A casted block molding apparatus, including a mold, first and second filler boxes, and a pressing mechanism. The first filler box is displaceable along opposed directions between an overlapping position where a first bottom opening is located over the mold cavities and a retracted position away from the mold cavities. The first bottom opening is closed by a first cover in the retracted position and is open over the mold cavities. The second filler box is mounted to the first filler box and displaceable therewith along the opposed directions. The bottom opening of the second filler box is closed by a second cover when the filler boxes are displaced from the retracted position to the overlapping position. The second bottom opening is open after the first filler box reaches the overlapping position. A method for molding casted blocks is also discussed.
