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.
