The invention relates to an apparatus for the pretreatment and subsequent conveying or plastification of plastics, with a container with a mixing and/or comminution implement that is rotatable around an axis of rotation, wherein, in a side wall, an aperture is formed, through which the plastics material can be removed, a multiscrew conveyor being provided, with at least two screws rotating in a housing, wherein the imaginary continuation of the longitudinal axis of the conveyor in a direction opposite to the direction of conveying passes the axis of rotation, where, on the outflow side, there is an offset distance between the longitudinal axis of the screw closest to the container, on the outflow side, and the radius that is parallel to the longitudinal axis, and in that the screws co-rotate.

A dosing apparatus (1) for dosing powdery, granular or flaked substances, comprises: a containment chamber (30) for receiving said substance; an homogenizing device (20) arranged internally of the containment chamber (30) and rotatable about an axis (Y) for homogenizing said substance; a dosing device (10) rotatable about a further axis (X) for conveying metered quantities of said substance outwardly the containment chamber (30); positioning means (50) for positioning the dosing apparatus (1) with respect to a support structure in an operative configuration.

Said further axis (X) is offset with respect to said axis (Y), so that, in said operative configuration, a vertical plane (P) containing said axis (Y) is passing outside of the dosing device (10).

A feed stock-to-vermicast converter, comprising an enclosed flow-through vessel having an upstream inlet for introducing convertible feed stock into a mixed epigeic bed conversion zone adapted to accommodate a population of epigeic vermicast-producing worms, communicating with a vermicast-converted feed stock outlet.

The invention relates to a mixing and conveying system for dry mortar materials. The dry mortar materials can be obtained from a storage silo (1) through an openable closure panel (3). A pipe (17), in which a drivable screw conveyor (4) is mounted, is arranged under the closure panel (3). The pipe (17) leads into a mixing and buffer container (18), in which a coil (20) is rotatably mounted on a central axis (19). The mixing and buffer container (18) has a volume which equals at least 1.5-times the minute capacity of the pump-screw conveyor (14). It is thus ensured that the dry mortar material is mixed therein with the added water for at least 90 seconds or longer. The mixing and buffer container (18) leads into a pipe (15) at the bottom having a pump-screw conveyor (14) which conveys the mixed mortar into a hose (5). The pump-screw conveyor (14) can be allowed to run backward. The coil (20) runs continually such that the mortar is constantly agitated to prevent setting.

The invention relates to a preparation process of a modified polyamide wax for coatings and a formed coating. The coating includes 0.5-5 parts by weight of modified polyamide wax; the preparation process of the modified polyamide wax for coating includes the following steps: S1, ratio of raw materials:raw materials include water-based polyamide wax, water-based polyurethane, polyoxyethylene monostearate, the first composite modifier, organic amine, organic solvent, the second composite modifier, deionized water; S2, prepare the first complex; S3, add organic amine, organic solvent and the second composite modifier is evenly mixed, and the temperature is raised to 100-120 C. until the water-based polyamide wax is completely dissolved to obtain the first intermediate modifier; S4, deionized water is heated up and slowly added to the first intermediate modifier in the process. The coating system prepared by the invention has good leveling, stability and sag resistance.

The disclosed apparatus, systems and methods relate to devices, systems and methods for mixing particulate matter such as salt with moisture. In various implementations, the mixer is transportable. In various implementations the mixer comprises a hopper, at least one auger, and a mixing housing. Various implementations, additionally include at least one liquid tank.

Systems and methods are provided for integrated system for producing hydrated lime slurry from calcium oxide using dry calcium hydroxide as an intermediary. A hydrator is configured to receive calcium oxide and to mix the received calcium oxide with water to produce dry hydrated lime. A dry hydrated lime transportation mechanism is configured to transport dry hydrated lime from the hydrator on a continuous basis over a period of time. A storage silo is configured to receive the dry hydrated lime from the transportation mechanism. A dispensing system is configured to dispense dry hydrated lime from the storage silo into a slurry tank for combining with water to generate hydrated lime slurry.
