discrete element study mixing in an industrial sized mixer

In this study, the segregation and dispersion of binary particle species of the same size but different densities in liquid fluidised beds have been investigated based on the analysis of computational fluid dynamics - discrete element method (CFD-DEM) simulation results.The vertical fluid drag force acting on the particles was found to be

In general, the definition is also open to other factors, e.g. the FDA definition is to have uniform character and quality, within specified limits, i.e. production period, quantity of material processed, quantity of material produced or production variation while material traceability is a key element.

CFD Consulting Services. At Predictive Engineering, we developed our expertise in computational fluid dynamics (CFD) consulting with years of CFD project work in medical, aerospace, marine, HVAC, civil and automotive. Our work has been extensively benchmarked by experiments and in-service testing, giving us the necessary validation experience

Discrete element method modelling is used to study the effect of particle shape on the flow dynamics and mixing in a high shear mixer. The blade generates strong flow over its top surface while compacting and pushing forward particles that are directly in front of the blade. A complex three dimensional flow is established with vertical and radial flow components that are shape dependent

Discrete element model (DEM) simulations of the discharge of powders from hoppers under gravity were analyzed to provide estimates of dosage form content uniformity during the manufacture of solid dosage forms (tablets and capsules). For a system that exhibits moderate segregation the effects of sample size, number, and location within the batch were determined.

Shelling Machines Market Insights, Trends & Growth Outlook. Shelling machines are mainly used to separate nuts such as almond, peanuts, and cashew from its shell. The machine includes a separating chamber, shelling chamber, and a motor (1HP). Shelling or separation is an important process in the production of

In this study, a discrete element method is employed to simulate the mixing process of solid particles in a horizontal ribbon mixer with a double U-shaped vessel. A mixing index, i.e. the so-called Lacey index, is adopted to evaluate the mixing quality of particles.

1.0 Project Brief. This individual design project entails the development of a process to produce 5000 tonnes of acetylsalicylic acid (Aspirin) per year. The plant will be located in the UK. The feedstock to the plant are; solid salicylic acid, acetic anhydride and sulphuric acid which act as a catalyst.

MGP/MG mixing consoles feature studio-quality preamps, powerful digital processing, and a rugged, reliable construction. They can easily adapt to a truly impressive range of applications from live performance, party with DJ, corporate events to fixed installation.

The research was conducted on the mixing line in an industrial feed plant in the following unit: a feed mixer, an intake hopper and a bucket conveyor (Fig. 1). Scheme of a mixer and its parameters, including the presented mixing screw inserted inside the mixer is presented in Fig. 2.
