A mixing device, in particular bulk material mixing device, with at least one mixing container comprises a receiving region for receiving a material to be mixed, with at least one mixing unit which is configured for mixing the material to be mixed that is present in the mixing container, and with at least one lump breaker unit comprising at least one cutter element which protrudes into the mixing container, wherein the at least one lump breaker unit is arranged in a frontal region of the mixing container.

A mixer for synthetic quartz includes a mixing barrel (1), a power transmission system (2), a mixing system (3), and multiple material receiving receptacles (4). The power transmission system is provided above the mixing tank. The mixing system is provided inside the mixing tank. The power transmission system is used to drive the mixing system to move. An opening is arranged at each of two ends of the material receiving receptacle. The multiple material receiving receptacles (4) are arranged at a top portion of the mixing tank, and end portions of two adjacent material receiving receptacles are spaced apart from each other without contact there between. A resin experiences low flow resistance in the material receiving receptacle, and thus can fall smoothly without accumulating in the material receiving receptacle. Moreover, the material receiving receptacle can be cleaned easily.

A dynamic mixer attachment is disclosed, which is adapted for use with conventional multi-component cartridges. The mixer has dispensing and drive axes that are offset relative to each other to enable use of the mixer with conventional multi-component cartridges. Also disclosed is a dispenser adapted for use with the mixer attachment and conventional multi-component cartridges.

A vertical low-pressure reactor with stirred tank for leaching polymetal minerals and concentrates of lead, copper, zinc, iron and/or the mixtures thereof, in a solid-gas-liquid three-phase suspension system. The low-pressure vertical reactor with stirred tank consists of: a cylindrical vertical container with three or four deflectors evenly distributed across the 360; a stirring system made up of two impellers coupled to a rotary shaft, that provides adequate reaction and interaction of the metal species of interest; a space of the volume of the reactor, corresponding to 20% to 35% of the total volume of the container, located at the top of the reactor and which acts as a gas chamber that provides a continuous feed of oxygen; and a system of coils placed on the outside or inside surface of the reactor to ensure efficient heat-transfer reactions and controlled kinetics.

A method for mixing a biological suspension includes disposing a biological suspension within a compartment of a container, the biological suspension comprising cells or microorganisms suspended within a nutrient growth medium; and rotating a first drive line and laterally spaced apart second drive line within the compartment of the container so as to cause the drive lines to twist into a helical configuration and mix the biological suspension.

A particulate material sensing and agitation control system of an agricultural system having a drive system configured to operate an agitating system, and a controller having a memory and a processor. The controller is configured to receive at least one sensor signal indicative of a profile of a particulate material within the agricultural system, and output a control signal to instruct the drive system to operate the agitating system in a selected operating mode of a plurality of operating modes based on the profile of the particulate material. The agitating system is configured to interact with the particulate material in each operating mode of the plurality of operating modes, and the plurality of operating modes includes an agitation mode and a leveling mode.

A particulate material sensing and agitation control system of an agricultural system includes an agitator configured to induce movement of particulate material through the agricultural system, a drive system coupled to the agitator, and a sensing system configured to determine a current flowing through the drive system. The drive system is configured to move the agitator, and the drive system is powered via an electrical circuit. The sensing system includes a first input coupled to a first point on the electrical circuit, the sensing system includes a second input coupled to a second point on the electrical circuit, the sensing system is configured to determine a voltage differential between the first point and the second point, and the sensing system is configured to determine current flowing through the electrical circuit based on the voltage differential.

The present invention consists in a reactor, a system and a method to process products such as polymers, where the reactor is formed by a vertical structure made up by a concentric ferrous inner tank and an external tank opened by the lower end, between which a jacket is arranged, where said reactor comprises: an upper lid; at least an inlet for material; an overhead valve in the at least inlet duct for material; at least one chimney; a stirring unit comprising a vertical axis connected to: a plurality of main blades fixed to it in a perpendicular way; a set of secondary blades perpendicularly joint to a sub-axis connected in angle to said vertical axis; a structure of lower blades; a discharge element comprising an opening and closing valve connected to a tray; and an air inlet located in one of the faces of the external tank.

The present invention relates to an apparatus and a method for producing a polymer latex resin powder, and according to one aspect of the present invention, there is provided an apparatus for producing a polymer latex resin powder comprising a first flocculation tank to which a polymer latex and a flocculant are each supplied, wherein the first flocculation tank is provided with a stirring part including a rotation axis and one or more impellers mounted on the rotation axis, and a discharge line, and the first flocculation tank is configured to operate as a closed system upon operation of the stirring part.

A method for assembling a mixer-container intended for receiving a biopharmaceutical fluid includes providing a container with a mixing device including at least one shaft having an adjustable length, and at least one first bearing attached to a wall of the container, the shaft extending at least into the inner space from the first bearing; a rigid outer device that compresses the container; and a drive motor located outside the container, the first bearing of the container is placed so as to be spaced apart from the motor, and the length of the shaft is adjusted along the main axis by arranging the shaft opposite the motor to enable the motor to rotate the shaft.
