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.

An apparatus for forming soft mud cladding or paving articles, comprising an assembly for loading a mix in a mold box which is open upward and is provided with at least one impression for forming a corresponding blank provided with a laying surface which faces toward the outside of the impression, the mold box being movable along an advancement direction through the loading assembly, elements for skimming excess material loaded into the mold box, at least one assembly for overturning the mold box for the extraction of the at least one blank, an assembly for drying and firing the at least one blank so as to obtain a corresponding cladding article; the skimming elements comprise at least one skimming element which is forms at least one profile which substantially matches the profile of the laying surface of the blank being processed.

A plant for producing a concrete prefabricated component includes a plurality of stations, a transport system to transport the production pallet through the plant, and a 3D printing station having a layer depositing device for depositing a particulate aggregate on the production pallet and having a printing head for controlled delivery of a water-binder mixture. The plant also includes a storage device to store particulate aggregate, a conveying device to convey the particulate aggregate to the layer depositing device of the 3D printing station, a mixing device for mixing the water-binder mixture, a feed device to feed the water-binder mixture to the printing head, and an unpacking station in which a concrete prefabricated component printed in the 3D printing station on the production pallet can be unpacked from an unbound particulate aggregate.

[Object] To provide a building material manufacturing apparatus and a building material manufacturing method each of which is suitable to vary, in a receiver width direction, a building raw material deposit amount on a building material forming receiver that receives a building raw material under a sieve portion that screens the building raw material.

[Solution] A building material manufacturing apparatus includes a sieve portion 10 and a receiver 30 that receives a building raw material M that has passed through the meshes of the sieve portion 10. The sieve portion 10 includes a series of sheets that are each capable of performing a wave motion when the apparatus is operating, that have an inclination, and that are arranged in a direction of the inclination. The series of sheets include a sieve sheet 12 and a sieve sheet 13 positioned below the sieve sheet 12. In the sieve sheet 12, meshes having an identical size are arranged at a regular pitch in a sheet width direction W. In the sieve sheet 13, meshes having two or more different sizes are arranged or a mesh region R1 and a non-mesh region R2 are arranged, in the sheet width direction W. The receiver 30 is movable below the series of sheets. The building material manufacturing method includes, by using the apparatus, forming a mat on the receiver 30, the mat including a first layer formed from a part of the building raw material M that has passed through the meshes of the sieve sheet 12 and a second layer formed from a part of the building raw material M that has passed through the meshes of the sieve sheet 13.

Plant (2) for the production of slabs made of composite stone material from a mix (M) containing granules of stone or ceramic or glass material and a binder, comprising at least one temporary support or mould (S), a distributor for the mix (M) designed to distribute a layer of mix (M) on the temporary support or mould (S), a station (4) for performing compaction by means of vacuum vibro-compression of the mix (M) arranged on the temporary support or mould (S) and a station for hardening the mix (M) so as to form the finished slabs. The plant (2) comprises a device (1) positioned downstream of the distributor and upstream of the compaction station (4) and comprising means (16) which act on the top surface of the mix (M) for pre-compaction and levelling of the mix (M) arranged on the temporary support or mould (S). The invention also relates to a method for the production of slabs of composite stone material from a mix (M).

A material distribution apparatus and preparing an artificial stone plate using the material distribution apparatus includes a belt material distribution device including a material distribution hopper and a conveying belt. The conveying belt is located at a lower portion of the material distribution hopper. An upper surface of the conveying belt is inclined. The material distribution hopper has a first wall and a second wall. The first wall is an inclined wall with an upper end away from the second wall. A discharge outlet is provided below the second wall. An upper portion of the second wall is vertically mounted, and a lower portion of the second wall has a circular arc portion and a discharge portion which forms the discharge outlet with a surface of the conveying belt therebetween.
