Mechanized Balling Disc Machine (Pelletizer) for Industrial Development in Nigeria Ikebudu Kingsley Okechukwu Abstract The aim of this project is to design and construct a balling disc machine for the production of balls /agglomerates pellets from a mixture either in its powder or molten form. This idea came up during the

The Pelleting Process For many years, pelleting was considered an art, a process involving imprecise measurement, uncertain results, and that undefinable quality of feel. This socalled "art" of pelleting came about in an environment lacking the understanding of the effects occurring when the differing

8 Centrifugal separation The basic equations for most centrifugal modelling were introduced in Chapter 5. The liquid drag force was given in equation (), under streamline flow, and the centrifugal field force was provided in equation (). It is a simple matter to equate these to arrive at an
In industrial process engineering, mixing is a unit operation that involves manipulation of a heterogeneous physical system with the intent to make it more examples include pumping of the water in a swimming pool to homogenize the water temperature, and the stirring of pancake batter to eliminate lumps (deagglomeration). Mixing is performed to allow heat and/or mass ...
Commercial spherical titanium powder in the current market is almost all produced by atomization methods or plasma spheroidization. There are a large variety of atomization techniques. Among them, GA, PA, and PREP are used commercially for the production of spherical Ti alloy powders.
For ≈100 μm thick powder layers, the measured absorptivity was found to be two times that of the bare polished discs for lowlaser power. There is a sharp decrease when full melting of the powder tracks is achieved, followed by a keyholedriven increase at higher powers, similar to the bare disc case.
Apr 13, 2016· Centrifugal and Submersible Pumps have one thing in common, there is no one size or type that fits all applications. Different impeller and pump body styles are required to do different jobs. Here are some of the different impeller types and what they are used for: 1) High Head Closed Channel Impeller – highefficiency [.]
Powderscale computational models can reproduce the multiphysics process of SLM. In this study, we couple the Finite Volume Method (FVM) and Discrete Element Method to model the deposition of powder particles, and use the FVM to model the melting process, both with ambient air.

The detailed dynamics of powder spattering in the LPBF are still not fully understood. Here, we report insights into the transient dynamics of powder spattering in the LPBF process that were observed with insitu highspeed highenergy xray imaging. Powder motion dynamics, as functions of time, environment pressure, and location, are presented.
