Method for compacting particulate material by compression

Abstract

The invention relates to a method for compacting particulate material by compression. The invention especially relates to a method for compacting particulate material, including a compression compacting method for preparing units of particulate materials. Said particulate materials to be treated can comprise, but are not limited to, cement, calcium, gypsum, mortar, combinations thereof and the like, in order to improve the packaging, storage, transport, presentation, dosage and preparation thereof, thereby benefiting the manufacturer, the distributor and the consumer. The invention reveals the possibility of applying different pressures for the compression and shaping of the compacted product into different geometrical shapes, for the packaging, storage, transport, presentation, dosage, preparation and use thereof, from the opening of the packaging to the final application.

1 . A method for compacting particulate material by compression, comprising: (i) a first step of selection of the particle size of the particulate material, by a first sieving; (ii) a second step of placing the particulate material in a compression device, wherein an additional content of this particulate material is added, equivalent to the interstitial air with respect to the total capacity of the material in the compression device; (iii) a third step wherein said compression device is centered on the compression machine; (iv) a fourth compression step, wherein the material is compressed and compacted at a pressure between 2.3 and 3.8 MPa, preferably, 3 MPa; (v) a fifth separation step of the compressed material of the compression device; and (vi) a sixth step wherein, once the compressed material is removed, it is conformed to the unit of particulate material ready for packaging in a compression state.
