Practice for Evaluation of Flushing Vehicles for Pigment Wetting Using a Vacuum Modified Sigma Blade Mixer

Optimization of solvent debinding process parameters for powder injection molded 316L stainless steel (SS) has been reported in this research work. Powder gas atomized (PGA) 316L SS was blended with a multicomponent binder in Z-blade mixer at 170°C ± 5°C for 90 minutes. Feedstock was successfully injected at temperature 170 ± 5°C. Injection molded samples were immersed in n-heptane for 2h, 4h, 6h and 8h at temperatures 50°C ,55°C and 60°C to extract the soluble binder components. Scanning electron microscope (SEM) results attested that soluble binder components were completely extracted from injection molded samples at temperature 55°C after 6h.

Destratification of reservoirs by the use of artificial mixing is a method of improving the impounded water quality. In order to design a destratification device at Stocks Reservoir, NW England, a Computational Fluid Dynamics model was used to trial different types and sizes of mixing device. It was found that a perforated pipe bubble mixing device performed far better than a large banana blade mixer at destratifying Stocks Reservoir. Two important criteria for the effective operation of a mixing device were established. These were a minimum upflow velocity of entrained water through the reservoir, and the need for a reverse flow along the surface of the reservoir away from the abstraction point. These criteria have been incorporated into design equations which can be extended to use at other reservoirs. A bubble mixer was installed at Stocks Reservoir, and has been shown to fully destratify the reservoir and to reduce the levels of dissolved manganese in the water by more than 50%.

The paper presents purpose equations describing the uneven mixing depending on the number of the mixer blade impacts per unit of concrete weight as well as the weight of the mixture that have an impact on blades of the slow-speed mixer. Based on the literature review and analysis of the mixing process conducted in the Samara State Agricultural Academy, the design of the blade mixer was developed. The mixer consists of a body where there is a horizontal shaft with working bodies, made in the form of radial blades of helical shape. There are received equations that allow determining the concrete uniformity depending on a number of the impacts of the mixer blades per unit of the concrete weight as well as on the concrete weight that act on the blades of the slow-speed mixer. The power function is adequately described by the experimental results of 98 % confidence probability. In the studied areas of changes in independent factors rational values of the number of impacts per unit of the concrete weight is not less than 800 PCs/kg, as well as the concrete weight having impact on the blade of the slow-speed mixer is not more than 0,001 kg/PC.
