From the aspect of factory hygiene and other reasons for sanitation, pneumatic conveying of granular solids has been increasing recently. Generally, this transportation method works efficiently in situations in which the velocity of the air and the concentration of solid materials in the duct is high. On the other hand, high velocity transportation causes the breakage of granules especially when the materials conveyed are brittle. Reasons for the breakage of granules are thought to be due to the collision between particles and the impaction of particles with the duct wall. As the results of the breakage, usually, size reduction of granules occurs, this means the products are of poor quality. In trying to solve these problems we made test equipment in which the granules are conveyed very slowly (average velocity
