Agora Services Plate Silos are suitable for most powder and granular materials. Their high quality design can accommodate the increased stresses where high capacity filling and emptying takes place at frequent intervals. For materials with difficult flow characteristics such as soya meal, or for heavy products such as coal, ash, etc. the Plate Silo can be arranged with a flat floor to receive the Agora Services unloader where consideration in the design of the silo is taken for mass flow emptying loads.
Agora Services Plate Silos for use with planetary discharger include all of the features outlined except that the hopper is replaced with a flat floor to receive the discharger. This floor is either in steel, supported by a steel entablature, or support skirt in steel or concrete. Alternatively a concrete floor supported by a concrete skirt.
Calculation of internal pressures is carried out in accordance with DIN 1055 and BS 5061 as appropriate. Steelwork is designed in accordance with BS 449, plastic theory being avoided for all primary structures.
At a high anticipated number of loading cycles, fatigue is taken into account, in particular the performance of joints under cyclic loading is given special attention. External loading is calculated to CP3 Chapter V, Part 2, reference being made to other codes as necessary for wind drag coefficients.
