A pressing device for providing a bale from plant material, including a pressing chamber with a pressing space to which plant material can be supplied, a pressing element movable from an initial position into an end position with a drive apparatus for compressing the plant material, and a binding apparatus, wherein the pressing space is delimited laterally by a wall for forming a pressing box, and an abutment delimits the pressing space, against which abutment the plant material is compressible during the movement of the pressing element into a first partial bale, wherein the first partial bale provided in this manner is transportable through a transport opening of the pressing space into a following space, wherein at least one further partial bale, via the pressing element, can be provided by compressing further plant material introduced into the pressing space against at least one abutment arranged at the pressing chamber.

Provided herein is a system for manufacturing a core of a vacuum insulation panel, the system comprising: a plurality of molding cast parts disposed along one direction, and providing a molding space for core material to be supplied and press-molded; a plurality of raw material suppliers distanced from one another, and supplying core material to the molding space; a press-molder disposed between the raw material suppliers, and receiving the molding cast part where the core material is supplied through the raw material supplier, and pressing the molding space; and a carrier transferring the molding cast part after the core material is supplied by the raw material supplier and the molding space is press-molded by the press-molder.

A mixed collection and compression device for dust and thin metal includes a separation mechanism used to sieve a flowing gas therein into a dust-containing gas and a metal material; a filtering mechanism connected to the separation mechanism and used to filter dust in the dust-containing gas; an inert powder adding mechanism connected between the separation mechanism and the filtering mechanism and used to add inert powder into the dust-containing gas during transportation; a compression mechanism connected to the separation mechanism and used to collect and compress the metal material; and a power gas source used to provide a negative pressure environment for a gas inside the separation mechanism to make the gas sequentially pass through the separation mechanism, the inert powder adding mechanism, and the filtering mechanism. It has the effects of reducing the explosion risk and improving the safety of field work.
