Dairy Diagnostics Tool Box Factsheet 1: Feed Storage Tables Source: Dairy Freestall Housing and Equipment, NWPS 7, 6th Edition, 1997 Sizing Silos Crop moisture is an important consideration in determining silage needs and acreage requirements. But silos should be sized based on a dry matter, DM, basis for each type of forage desired.
This spreadsheet will help you design a bunker silo(s) which uses nearly vertical walls. The spreadsheet is organized into three sections. The INPUT section (cells A15-E36 which are boxed in Figure 1 and in blue text in the spreadsheet) gives you the opportunity to enter information about your needs and wants in a bunker silo silage storage system.

The designer should verify that the design complies with NRCS standards and that the standard applies to the site. The designer must understand the assumptions and calculations contained in the spreadsheets and is responsible for their use. Most if not all spreadsheets contain macros. Many engineering spreadsheets are available for use.

THE STRUCTURAL DESIGN OF LIGHT GAUGE SILO HOPPERS by J. Michael Rotterl Synopsis Elevated light gauge silos usually have a conical discharge hopper at the bottom. Although this hopper often carries much of the total weight of the stored solids within the silo…
The Sub-Committee first published "Design Recommendation for Storage Tanks and Their Supports" in 1984, and amended it in the 1990, 1996 and 2010 publications. This current revised recommendation provides bulk material pressures for silos and further guidance on seismic design methods for storage tanks based on the horizontal load-
Tank Capacity Calculators. Dry Bulk - Tank Capacity Calculator for figuring the tank size and tank volume of dry bulk storage tanks including: skirted tanks with door access, drive through skirted silo, elevated tanks with leg support and elevated tanks with structure support.; Liquid Flat Bottom - Capacity Calculator for figuring the tank size and tank volume of Liquid Flat Bottom Tanks.
Instructions for Use of Silo Volume Calculator. For reasonable accuracy, make all measurements to the nearest centimetre (0.01 of a metre) then enter them into the calculator in metres (e.g. if you measure 1052 cm then enter 10.52 m).
Silo Stress Tool SILO STRESS TOOL calculates stresses in silos and bins with simple geometry (e.g. a vertical section plus a hopper). The calculation can be performed for the filling stress state (stress state after an empty silo has been filled) and for the discharge stress state (valid after some bulk solid has been discharged form the (mass flow) silo.
The following data must be known in order to calculate the silo : The Powder Flow Function, the wall friction angle, the static angle of internal friction Knowing the characteristics of the product to discharge is the 1st and mandatory step to properly design a hopper.
The stress distribution across the periphery of the silo is another example of the different points of view: whereas a strong irregular distribution of the stresses on the silo wall is quite unimportant for the design of a feeder, these different stresses cannot be neglected for the structural design of the silo walls. 2 Stress calculation

design considerations for silos are therefore a key aspect of bulk solids handling systems. The chapter refers extensively to the provisions of the recently developed European stan-dards for silo pressures (EN 1991-4 2007) and for metal silo structural design (EN 1993-4-1 2007), for which the author was the chief contributor and editor.
