Our target was to get a modified coefficient

based on an experimental data.

The percentage of the 1kg sample which is

thrown out ( under action of the "flush

effect" ) from the special short pipe, and

bulk/specific density - the only required

factors for the coefficient calculation.

Note: we carried out hundreds of tests to

find out the only length/dia ratio of the pipe

and initial pressure to get reliable and

repeatable results.

Next step: we have calculated coefficients

for long row of known materials and data

of dense phase pneumatic systems,so

each new coefficient can be compared with

the known materials coefficients and put

in the row.

Now we can confirm that the new material

transportability (solid/air ratio as the function

of the distance ) will be similar to cement,

alumina, pulv.coal (dry or wet ),granular

potash or other.

We can confirm also when it is not worth

to use a dense phase system for the

tested mareial - solid/air ratio will be too

low - red light !
