Re: Coal Ash Stockyard.
Thank you my friends. I got the wrong data when calculating the pressure that the stacker will apply to the ground, the right one is 8 kg/cm2.
I guess the kind of testing we should do is to get a coal ash cylindrical sample, put it in a press and subject it to a pressure of 8 kg/cm2 multiplied by the safety factor, right? Do you know of any standard I should follow to run the test?
Regarding the tires, I'll look deeper into the numbers the desginer used to calculate the size of tires.

The conveyor will apply a pressure of 50 kgs/cm2 (due to its own weight and the conveyed material's), and we need to be sure if the pile of compacted coal ash will resist such load.

The easy way is to refer to the recommended tyre inflation. This assumes that the competent portable stacker designer has not overloaded the tyres to lower the machine price.eg. if you have high flotation tyres fitted & the tyre rating is not exceeded at your 5bar operation then you could comfortably stack over a swamp. Trust the tyre manufacturers: billions of drivers have to. ■

There is a test, the "proper" name of which elludes me at the moment, though you can actually test (geotechanical type test) the ground for a bearing pressure.

Coal Ash Stockyard.
Dear Bulkholic Friends,
I would like to know where can I find the compaction properties of Coal Ash, since we are working on a project that requires a portable radial stacker to be working over a pile of compacted coal ash.
The conveyor will apply a pressure of 50 kgs/cm2 (due to its own weight and the conveyed material's), and we need to be sure if the pile of compacted coal ash will resist such load.
Thanks in advance for your help,
Adrian. ■
