Disclosed is a separator device comprising a suction device to suck in air, and a wind-force sorting mechanism for sorting a mixture to separate projection materials from the mixture, wherein the wind-force sorting mechanism comprises: an airflow passage which extends horizontally from an inlet to an outlet thereof and in which an airflow is generated by suction force of the suction device; a mixture supply port formed on an upper side of a midstream region of the airflow passage; and a sorting section configured to allow a mixture containing projection materials and powdery/granular foreign substances to freely fall from the mixture supply port into the airflow passage to thereby cause the airflow to hit against the mixture so as to sort the mixture into a first group which move beyond a given reference height position, and a second group which fall without moving beyond the reference height position.

A vertical roller mill includes a housing, a chute that supplies materials to be grinded to a center portion of the housing, a grinder that is provided below the chute and grinds the materials to be grinded, an exhaust pipe that is provided above the grinder, a transport mechanism that forms an air flow for transporting, to the exhaust pipe, grinded materials grinded by the grinder, and a flow-constricting flow path provided between the grinder and the exhaust pipe and narrows a flow path area for the air flow, in which the flow-constricting flow path is formed between a first flow-constricting ring provided in the center portion of the housing and a second flow-constricting ring provided to protrude from the housing toward the center portion of the housing.

The invention discloses a system for squeezing, smashing and winnowing municipal solid waste (MSW). The system comprises a primary squeezing and smashing, device and a secondary smashing and winnowing device. The system of the invention has good effect m squeezing, smashing and winnowing, can greatly reduce the water content of MSW and efficiently separate the MSW into combustible matters and non-combustible matters, so as to facilitate further subsequent utilization of the municipal waste; moreover, an upper jaw of a jaw crusher is connected with a spring device, so that the squeezing pressure, smashing effect and processing capacity of the jaw crusher can be adjusted according to the amount of the MSW. In addition, the system of the invention is further provided with emergency brake switches, spring protection devices and a sieve, so as to ensure the stability and the reliability of the system.

An apparatus for the comminution of a botanical feedstock includes a vessel, a screen positioned in the vessel above a first feedstock outlet and spaced from the top of the vessel, and a blade rotatably mounted above and generally parallel to the screen. The blade has a leading side, a trailing side, and a radial blade length. At least a portion of the leading side has a cutting edge and at least a portion of the trailing side has a downwardly extending trailing portion. The downwardly extending trailing portion has a lower edge having a plurality of discontinuities along a radial length of the trailing portion. The cutting edge is spaced from the upper surface of the screen by a first distance and a lowermost portion of the lower edge is spaced from the upper surface of the screen by a second distance.

An apparatus for collecting dust from a cutting unit is provided. The apparatus includes a rotary valve operatively connected to the cutting unit, a conduit in fluid communication with the rotary valve, and a compacting machine disposed downstream from the conduit and configured to receive dust from the conduit. A blower is configured to pull air downstream to carry the dust into the compacting machine. The compacting machine produces a compact from the dust.

A rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. A liquid freezing agent is introduced into a container of the plant matter to fragment the undesirable matter while the desired portion rich in trichome remain intact.

A method is provided for pre-treating biomasses, more particularly, for pre-treating biomasses intended for a biorefinery or similar facility for producing biofuels. The method comprises the steps of shredding the biomasses, removing foreign bodies contained in the biomasses upstream of the step of shredding, and soaking the biomasses by immersing the biomasses in water upstream or downstream of the shredding step. A plant for pre-treating biomasses is also provided. The plant comprises a shredding station for shredding biomasses, a station for removing foreign bodies from the biomasses upstream of the shredding station, and a soaking station for soaking the biomasses upstream or downstream of the shredding station.
