A plant for conveying material for the production of structural concrete comprises a first container configured to contain a first amount of material, a first detection member configured to detect a variation in the first amount of material and first release members configured to enable and/or disable release of the first amount of material towards a mixing area of the first amount of material. The plant further comprises a second container configured to contain a second amount of material varying between a second minimum and a second maximum reference amount, a second detection member configured to detect a variation in the second amount of material and second release members configured to enable and/or disable release of the second amount of material towards a mixing area. In particular, an unloading opening of the second container is connected to the mixing area, whereas an unloading opening of the first container is connected to a loading opening of the second container or to a mixing area. A control unit is configured at least to enable said release members to release the first amount of material when the second detection member detects the reaching of the second minimum reference amount in the second container. The present invention also relates to a process for conveying material for the production of structural concrete.

The proppants processing system comprises one or more in-feed conveyors, one or more out-feed conveyors, one or more primary feed bin assemblies, one or more secondary bin assemblies, the primary and secondary bin assemblies each comprising one or more bins and one or more bin conveyors. The proppants processing system further comprises a final transport conveyor and a control unit adapted to control flow of the proppants. A method of processing proppants, the method comprising the steps of providing proppants comprising dry or wet sand; using an in-feed conveyor, transferring the proppants from a transport vehicle to one or more bins of a primary feed bin assembly; moving the proppants from the one or more bins to a feed bin conveyor; moving the proppants from the feed bin conveyor to a final transport conveyor; and using the final transport conveyor, moving the proppants to a blender.

The invention relates to improvements in the technical field of feeding solid materials to mixing devices. For this purpose, the solid-material feeding device, inter alia, is proposed. The solid-material feeding device comprises the slide, which can be moved between a first end position and a second end position through a conveying connection, which is arranged between a funnel and a solid-material outlet of the solid-material feeding device. By means of the slide, adhesions within the conveying connection can be loosened without having to remove the conveying connection.
