Disclosed is a bioreactor, especially a plug flow bioreactor, including an agitator running along a longitudinal axis for thoroughly mixing a dry solid biomass that is to be outgassed in a fermentation chamber. In said bioreactor, an agitator shaft is mounted exclusively in two opposite end walls of the fermentation chamber while at least one free end of the agitator is connected to a drive unit outside the fermentation chamber.

The invention focuses on a device for sequentially introducing additives in a polymer granulate and the use of the device for mixing the polymer granulate with the additives. The device consisting of a mixer with housing, comprising at least one mixer shaft attached in helix arranged non-continuous conveying pattern shapes, being rotated by a drive for the transport, whereby the mixer in the housing featuring an inlet for the polymer granulate to be mixed and each of the several subsequent inlets for the additive is followed by an outlet for the polymer granulate mixed with the additive, so that two or several mixing zones being formed in the mixer and whereby at least between at two mixing zones on the surface of the mixing shaft one section featuring a continuous screw conveyor instead of the non-continuous conveying pattern shapes, the section not being penetrable for returning solids from the subsequent mixing zone.

The present invention relates to a large-scale magnetic purification system, including: a liquid storage apparatus, capable of being connected to a liquid source and a waste liquid barrel through a liquid path system; a stirring system mounted above the liquid storage apparatus, where a stirring paddle of the stirring system is inserted into the liquid storage apparatus for stirring; magnets mounted around the liquid storage apparatus; a magnet actuating mechanism for manipulating the magnets to move away from or close to the liquid storage apparatus; and a control system, connected to the liquid path system, the magnet actuating mechanism, and the stirring system and controlling the liquid path system, the magnet actuating mechanism, and the stirring system.

A reactor assembly is provided for heating plastic material. The reactor assembly includes: a reactor vessel including a central axis; and an agitator mounted within the reactor vessel. The agitator includes: one or more blade(s) distal from the central axis for mixing contents of the reactor vessel in use; and one or more wearing parts mounted to the blade(s) to extend from the blade(s).

A blender includes a proximal section having a proximal upper housing and a proximal lower housing, a distal section having a distal upper housing and a distal lower housing, at least one intermediate section disposed between the proximal section and the distal section and coupleable thereto, each of the at least one intermediate section including an intermediate upper housing and an intermediate lower housing, a shaft extending through the proximal section, the distal section and the at least one intermediate section, and at least one blade disposed on the shaft.

The present invention is a method of mixing various viscous fluids. The mixing device is comprised of a shroud with helical blades inside connected to the central shaft and the shroud in spiral direction. By rotating the device in the fluid or paint, helical blades create a vortex like movement of the fluid and thus create suction of the fluid through the shroud, mixing viscous fluid at a greater rate. Field test showed that the devise is very effective in mixing viscous fluids by braking solids in the paint/fluids and lifting the settlements from the bottom of a container due to the radial and axial movement of the fluid. Device was found very easy to use due to the fact that the kickback of the mixer was minimized. It also showed that the splatter of paint was almost eliminated in the open container.

A liner element for lining a vertical grinding mill agitator including one or more primary mounting portions configured to releasably mount the liner to a shaft of the agitator; and one or more secondary mounting portions configured to releasably mount one or more wear members to the liner. A liner segment including the liner element and at least one wear member is also disclosed.
