Systems and methods of using a surrogate machine learning model, based on a CFD model, to predict the mixing quality in steady state mixing tanks are provided. An exemplary method includes generating a plurality of training CFD models for a plurality of training steady state mixing configurations based on a plurality of steady state mixing factors associated with each training steady state mixing configuration; calculating a mixing quality for each training steady state mixing configuration using each respective training CFD model; generating a training dataset that includes the steady state mixing factors associated with each training steady state mixing configuration, and the calculated mixing quality for each training steady state mixing configuration; and training a machine learning model, using the training dataset, to predict mixing qualities for steady state mixing configurations based on based on steady state mixing factors associated with the steady state mixing configurations.

A reactor for gas-liquid mass transfer between a gas and a liquid or slurry includes a tank for receiving the liquid or slurry having a wall; a drive shaft; an upward pumping impeller; and an aerating apparatus disposed above the upward pumping impeller and extending between the drive shaft and the wall of the tank at a first distance (d1) from the drive shaft and at a second distance (d2) from the wall of the tank, the aerating apparatus encircling the drive shaft at least partially. The aerating apparatus has an outward inclined or curved inner surface for directing at least a part of the flow over the inner surface.

In a method of producing nanoconcrete according the bottom-up approach of nano technology with the High-Energy Mixing of composition including cement, water, sand, additives and superplasticizers, the mixing is performed with flow of mixture characterized by Reynolds number and Power number in the range of 20-800 and 0.1-4.0 respectively with installation a disk horizontally into mixing assembly on the top layer of activated mixture coaxially with vertical axis of assembly and with the axis of impeller rotation on the adjustable level to avoid destroying created gel as a result of interruptions of process, to increase laminarity of the mixture flow, energy absorption by the mixture, and shear stress for creation additional quantity of the nanostructured Calcium Silicate Hydrate (C-S-H) gel necessary for making nanoconcrete.

Agitation assemblies for a spreader having a rotatable feeding mechanism are provided that utilize the rotation of the feeding mechanism to oscillate an agitation member within the spreader. A crank is coupled to the feeding mechanism and a connecting linkage connects between the agitation member and the crank so that as a drive mechanism rotates the feeding mechanism to dispense spreading material towards a dispensing opening, the connecting linkage oscillates the agitation member. The agitation member can be a baffle or agitation plate. The oscillation of the agitation member can be pivoting or sliding oscillation.

The invention relates to a high-concentration mixer (1) for producing a suspension (2), comprising a stationary container (3) and an agitator (8) arranged in the container axis (7), which agitator is connected to a motor via a flange (9) provided in the region of the container bottom (4), which motor is designed for rotationally driving the agitator (8) for mixing the suspension (2) provided in the container (3), wherein the agitator (8) has helical coils (11) which bring about a vertical downward flow (12) of the suspension (2) in the centre of the container (3) and a vertical upward flow (13) of the suspension (2) in the region of the container wall, wherein the flange (9) comprises at least one blade (15) provided on its circumference, which is designed for wiping the suspension (2) from the container (3) and for supporting the vertical upward flow (13) of the suspension (2) in the region of the container wall.

A pivotal rigid vortex shield configured for use in combination with a propeller-type aerator has a vortex shield, and a rigid support affixing the vortex shield to a support system. The support has a horizontal support bar with at least two cross arches, first and second vertical pivot and locking members, and a top arch affixed between. A pintle couples the support to vortex shield, and defines a pivotal axis about which the vortex shield is configured to rotate. A locking member may be at least one quick release pin that in an operational configuration simultaneously passes through at least a portion of at least one of the vertical pivot and locking members and at least a portion of the vortex shield support to prevent rotation of the vortex shield about the pintle. In a service configuration the pin is removed to permit the vortex shield to rotate.
