Circular structure, as a theoretical term in literature, refers to a narrative or compositional technique where the story concludes by returning to its initial point, creating a closed and self-referential loop. This device challenges conventional linear storytelling, emphasizing thematic or symbolic significance in the repetition of narrative elements.
Jesus Chavez Sagarnaga, Director of Structural Engineering, Jenike & Johanson, Inc.

Hopper bottom is provided at the bottom of the tank to dispose the collected sludge. Types of Sedimentation Tanks based on Shape Circular Tank Circular sedimentation tanks are preferred for continuous vertical flow type sedimentation tanks. In this case influent is sent through central pipe of the tank and radial flow takes place.

A circular organizational structure is a form of hierarchical structure where senior-level employees occupy the inner rings of a circle and lower-level employees the outer rings. Unlike a traditional hierarchical structure where directives are sent down a linear chain of command, leaders in a circular structure are not considered to sit at the top of the […]
The present invention regards a hopper structure for containing and treating loose material, which includes a tubular section, upper in use, a lower tapered section equipped with a suitable discharge mouth, a support device for at least the upper tubular section, and a guide device designed to allow the lower section to move between a closed position against the upper …

The second stage is to choose a geometric form for the storage container, usually either circular, with conical hopper section or rectangular, with pyramid or slot outlet. The outlet region may be transformed to a chisel shape …
While such a structure may lend itself to efficient production, it is not well adapted to organizations wanting to innovate or organizations which require adaptability in changing times. The circular organizational structure is a superior response for organizations seeking to pursue objectives such as agility, employee involvement or innovation.
Learn about the Transition Hopper! How it works, its components, design, advantages, disadvantages and applications.
circular opening will normally be smaller for a conical hopper than the half-angle {3p for a corresponding wedge, plane-flow hopper. In addition the opening size or diameter Dc for a conical hopper is typically twice as large as the minimum slot width Dp for a wedge hopper. Thus it is clear that a plane-flow hopper is more
The use of circular silos with independent hopper structure in the process of storing grain and other granular material has become very extensive nowadays. The structural analysis of silos is of a complex nature and requires sophisticated mathematical techniques for proper calculation. Janssen, Airy and Reimbert
Hoppers are rectangular bins with the bottom floor consisting of four sloping slabs. Silos are generally circular in cross section. For self-cleansing and for emptying, it is supported on a …
The second stage is to choose a geometric form for the storage container, usually either circular, with conical hopper section or rectangular, with pyramid or slot outlet. The outlet region may be transformed to a chisel shape …
Additionally, the factors are responsible for wall stiffness linked to reinforced concrete additives, circular hopper bending attributed to the eccentric withdrawals, variations in the strength and the diameters of the steel reinforcements, uneven distribution of the cement strength, wall bulking due to inadequate structural support, corrosion ...
The storage bin, silo or hopper is one of the most important items of equipment in any bulk solids handling installation, since a poorly flowing hopper can have repercussions extending …
Diameter of the circular slab = 3 metre = 3000 mm; Diameter of main bars = 12 mm; Diameter of distribution bars = 8 mm; Calculation For Main Bars. First, we need to calculate the number of rods required for the circular slab. No. of rods = (Diameter of the circular slab – Clear Cover on Both Sides) / Centre to centre distance
The extra capacity afforded by a 'V' shaped hopper also extends the residence time of the hopper contents. Processes that improve de-aeration also favour a more uniform discharge density of the hopper contents, which may be an asset on feed control, filling and packaging application for product that are filled by volume and sold by weight.
These are characterized as shallow structures. The angle of rupture of the material in case of bunkers, will meet the horizontal surface at the top of the bin, before it touches the opposite side walls of the structure as shown in the figure-1. Bunkers may be circular or rectangular (or square) in plan. Fig.1: Sectional View of a Bunker
