GLOSSARY OF EQUIPMENT 5 104-105 CHARACTERISTICS • The width of the suction hood mouths, for both waste inlet and outlet, must be equivalent to the useful width of the belts transporting the waste to be treated. • The heights of the suction hood mouths for both waste inlet and outlet must allow the waste to pass freely. This will depend on the grain size and flow rate involved. • Suction capacity. Depending on the system suction points, which can be from one to three, the following air flows are required with a depression of 3,000 to 3,500 Pa: › 1-Suction hood: from 15,000 to 20,000 m3/h air. › 2-Suction hood: from 30,000 to 35,000 m3/h air. › 3-Suction hood: from 40,000 to 45,000 m3/h air. These air flows have been calculated for a safety coefficient of 25% guaranteeing the proper operation of the facility. • The fan capacity must be enough to move a minimum air flow and a depression that can suction and transport objects with low density such as film, P/C and other light material particles such as dust through pipes, as well as through the air. • The depression at the fan must reach values from 3,000 to 3,500 Pa, depending on the distance between the fan and the capture point. In addition, the cross-section of the transport pipe and the load losses due to the various components (elbows, sights, etc.) must be considered. The power of the fans used in suction systems of standard package sorting plants range from 22 kW to 55 kW. 5. Semiautomatic suction in secondary sorting cabin.
