Inspired by the thread titled Stacking arb bags of logs I thought I would start this thread...
Carried out stage 1 of a simple experiment today, the pictures should speak volumes (pardon the pun...)
Picture 1.
A metal stillage dimensions 1.43m x 0.88m. Stretch wrapped to a height of 0.80m. (This gives an internal volume of 1.00672m3) loose filled with logs to a level top.
Picture 2.
A "cubic meter" vented log bag, filled with the same logs as were in the stillage in pic 1. Unshaken.
Picture 3.
The same bag with exactly the same amount of logs in it but having now been shaken/bounced
What I'm trying to illustrate here is that what I have up till now been terming a "cubic meter of logs" is clearly rather more. I will find out how much more in stage 2 of the experiment, this will involve emptying a bounced and brim full bag into the stillage and measuring exactly how much over a cubic meter there is in a "full " bag. I'm hazarding a guess at up to 0.4cbm over...
Perhaps worth mentioning here the first 2 things that spring to mind against bouncing the bags;
a. Notice how an awful lot of products have the words "contents may settle in transit". A loose volume is a loose volume, surely if shaken down it is no longer truly loose...
b. Would the bag manufacturers really recommend bouncing the bags when full of a heavy material?? I doubt it.
Picture 4.
Don't get me wrong, I have up until now also been bouncing the bags and topping them up not only so they look presentable but also so they are a more uniform volume and so they will stack safely. I am now rethinking both my pricing and my storage methods.
P.S.
The stretch wrapping I know is not suitable for storing logs due to poor air circulation but it has sufficed to create a quick measured cubic meter vessel... I'm planning to fit weld mesh to the sides but have not that far yet...
