摘要： The invention relates to a method for the mass decoration of ceramic products, comprising the following steps: spreading, superposed on one another, a layer (L) of granular or powder material and a decorative layer (3) on a support surface (2); transferring the layer (L) from the support surface (2) to an accumulation belt (T1), contiguous and aligned to the support surface (2), which is located at a lower height than the support surface (2), wherein the accumulation belt (T1) is mobile in advancement at a speed that is different from the advancement speed of the support surface (2), so that a variation in the thickness and longitudinal extension of the layer (L) is produced; pressing the layer (L) and the decorative layer (3).

摘要： A machine (1) for depositing ceramic powders comprises a supply device (2) and a distributor device (3) of the ceramic powders. The supply device (2) is configured to convey the ceramic powders receiving them from a process situated upstream of the machine. The distributor (3) is movable along a processing direction (X) which extends in a support plane and is configured to receive the ceramic powders from the supply device (2) depositing at least one layer thereof on the support plane during an advancement and/or reverse movement thereof along the processing direction (X). A system for making ceramic tiles or slabs is also claimed, comprising (i) the machine (1) for depositing ceramic powders, (ii) a conveyor belt (11) defining the support plane and (iii) a pressing device arranged along the support plane downstream of the machine (1) and configured to press at least one layer of ceramic powders deposited by the machine (1).

摘要： A preparing process for pressing particulate aggregates into a slab and a shaping apparatus are described. The preparing process includes: mixing particulate aggregates of different sizes and a liquid material as per a preset proportion to obtain a mixture; spreading the mixture flatly in a preset thickness onto a conveyor belt or into a mould frame; vacuumizing the mixture; shaping, wherein a pressing plate is disposed covering the mixture during the shaping procedure to constantly apply a downward pressure against the mixture; a ram disposed over the pressing plate continuously smashes the pressing plate, wherein during ram smashing, the pressure created by the pressing plate forms a continuous holding force to the mixture, the smashing force created from up-down motion of the ram is transferred to the mixture via the pressing plate.
The changes to the abstract are shown below:

摘要： Provided is a building material manufacturing apparatus and a building material manufacturing method that are suitable for efficiently manufacturing a building material while suppressing clogging of a sieve portion for sieving the building raw material. The building material manufacturing apparatus of the present invention includes, for example, a sieve portion 10 and a receiving tool 30. The sieve portion 10 includes a receiving and sending sheet 11 with no sieve openings, onto which the building raw material M is dropped, and at least one sieve sheet 12 with sieve openings that is located below the sheet. The receiving and sending sheet 11 and the sieve sheet 12 can perform undulating motion, are inclined, and are arranged side by side in the inclination direction. The receiving tool 30 is for receiving the building raw material M that has passed through the sieve openings of the sieve portion 10. In the building material manufacturing method of the present invention, for example, in a state in which the receiving and sending sheet 11 and the at least one sieve sheet 12 are performing undulating motion, the building raw material M is dropped onto the receiving and sending sheet 11, moved from the receiving and sending sheet 11 onto the sieve sheet 12, subjected to sieving by the sieve sheet 12, and the portion that passes through the sieve openings of the sieve sheet 12 is accumulated on the receiving tool 30, whereby a mat with at least one layer is formed.
