Elevator Leg Spout Capacities

When determining the required diameter of spouting, consider the following: Material flow characteristics, moisture content, cleanliness of material (no trash), spouting angle, speed of material entering the spout, possible bottlenecks created by distributors, elbows or other devices in the system.

'*Note: The above information should be used as a guideline suggestion only.  No liability is assumed for its use. All considerations mentioned above will alter spout capacity and must be allowed for. Spouting for ground feed and other fluffy materials should not be set at less than 50 degrees. Some of these materials have unusual characteristics. Spouting for almost all materials should be vented if the spout angle is 55 degrees or more.
