Mixtures tested contained 10, 20, 30, 40, 50, 60, 70, 80 and 90% flotation tailings with 90, 80, 70, 60, 50, 40, 30, 20 and 10% magnetic concentration tailings, respectively, in relation to the dry unit
On contrary, maximum dry unit
weights of both cohesive soils were found to decrease with the addition of contaminants.
Natural dry unit
weight was determined to be in range of 13.5 to 22.5 KN/ m3.

Figure 4 indicates that the highest maximum dry unit
weight value was obtained by the addition of 1% by weight olive waste ash bentonite.
Flooring, siding, door and window manufacturers and interested entrepreneurs are inquiring about buying either the wood or their own Eco Dry unit
. Each plant can create 40-60 jobs the spokesman says, adding the firm is targeting Minnesota and Wisconsin and Northern Ontario towns for sale of the equipment.
In this table, internal friction angles were calculated from dry unit
weight using the relationship shown in Figure 4.
However, the Bete Twist and Dry unit
has a greatly simplified design, which offers higher clog-resistance and is quicker to change.
"These dry units
are pressurized with nitrogen for shipping, and I have heard of technicians who forget to remove the nitrogen or do not know it is there and end up mixing R-22 with nitrogen, causing damage to the systems," Paz says.
Both humidified and dry units
accept half-size pans and offer a temperature range of 80 degrees Fahrenheit to 175 degrees Fahrenheit (27 degrees Celsius to 79 degrees Celsius).
Polytex dry units
use a powerful fan to extract the dust from individual or multiple work stations, trapping it in a filter bag system.
