The percentage of com-pression is plotted against the load. Thecurve forms luite a srnoothe and rs^larparabola with the vertex at the origin. At10,000 pounds pressure it approaches quiteclose to the horizontal, while at 2000 itapproaishes quite close to the verticle. Therefore, no load should be used ofless than 2000 pounds in manufacturing pro-cesses,as the particles are in a relative-ly loose condition. By inspecting the curveit becomes apparent that the most desiredworking pressure would be 3500 pounds. Fromthis point on the small amount of additionalcompression for increase in load does notwarrant its appliaation. The extra costsin machinery and the increased power require-ments would also prove a deciding new test was now run using an 18/5 ami; 45 Test for Compression. mixture. The results showed very littlechanh^e. The best pressure ranged between3250 pounds and 3750 pounds.
