Immersion of automotive parts in a fluidized bed of foundry sand is used to both strip the castings free from moulding sand and to heat-treat the castings at 500 °C. The fluid bed is heated by hot gases from a burner directed first into a serpentine

In response to the need in industry for a quick and reproducible method of measuring the flowability of powders in processes involving transport and storage, the apparently simple idea of measuring angle of repose has been revived. The simple tester

A knowledge of the degree of expansion of fluidized beds is needed by designers in order to calculate conversions in fluidized-bed chemical reactors and, in combustors or incinerators, the relative areas of heat-transfer surfaces immersed in the bed

This study reports the effect of vertical baffles on the group D powder mixing and drying characteristics in a batch fluidized bed dryer. Results obtained in this study showed that operating the fluidized bed dryer with vertical baffles gave better p

A range of commercially important powders (hydrated alumina, a silica aerogel, limestone, titania and zeolite) was attached to atomic force microscopy (AFM) cantilevers, and force–distance curves were studied for particle–particle and particle–

The dipleg can generally operate in three basic flow regimes; packed-bed, fluidized- bed flow and a dilute flow called streaming flow. The most common perception of an overflow dipleg is that it consists of a fluidized dense phase at the bottom and a

The dynamic characteristics of gas-solid flow patterns within a circulating fluidized riser have been investigated using an electrical capacitance tomography system. The tomograms show both an instantaneous and an average in time solids’ distributi

The industrial uses of fluidized bed jet grinding are increasing but the basic mechanism of comminution within such a mill is not well-understood and their design and prediction of performance is therefore largely very empirical. The effects of free

Two equipments for measuring the bulk density of powders have been used to assess the flowability of porous and non-porous powders in which particle size changes as a result of controlling the percentage of fine components in the mixtures. The Hosoka
