Abstract: A novel mobile self-contained stone-making and cement-forming factory comprises, in general, four main components, namely (1) a power plant, (2) a receptacle for receiving local aggregate, (3) a batching module for mixing aggregate with cementitious material and water and for feeding the batch to a compression station and (4) the compression station for compressing the batch into a stone, block, paver, tile, brick or other stone-type product of variable size, colour, and surface finish. These main four components are supported together on a trailer or other portable frame that can be towed or otherwise transported to the construction site. Optional compression plates can be provided to produce customized double-faced stone products. The mobile factory-enables efficient, inexpensive, onsite manufacturing of a broad range of different stone products.
