Direct deep blade

The horizontal pan mixer was used as a combined mixer-granulator in the early development of fertilizer granulation [3]. A typical machine is depicted in Fig. 4.1. It might be 7.5 ft (2.3 m) in diameter and 18 in. (0.5 m) deep and contain a 0.5 to 1 ton (0.5 to 0.9 Mg) batch of material. Rotation of the pan and mixing blades eccentric to the pan in opposite directions creates a constant state of agitation and, with the addition of plasticizing agent such... 

Sample Preparation A small coupon of polymer is removed from the sample using a pair of scissors or a razor blade. The dimensions of the coupon were square, 2-3 mm on a side. The coupon was exposed to a microgram of neat surrogate of diethyl ethylphos-phonate (DEEP) and allowed to stand until the compound had dissipated from the surface. Dissipation can involve either evaporation or diffusion into the bulk. The sample coupon is then attached to a sample holder using double-sided tape, and the sample holder attached to the direct insertion probe. 

Fig. 5.10. A schematic not-to-scale drawing of the specimen from the geomembrane and the steel pin to widen the specimen using the pin impression method. The dimensions are indicated in mm. The arrow shows the direction of extmsion of the geomembrane. In each case a new razor blade is used to punch a 1.5 mm deep notch. A conical steel pin with an end diameter of 4 mm is pushed into a hole with a diameter of 3 mm...
