Crusher Close Side Settings
The maximum feed size is approximately 8 0% of the feed opening. The open side setting is measured when the crusher is at rest. The setting is measured either top to top, or bottom to top, depending on the tooth profile of the jaw dies. The closed side setting can be calculated by deducting the stroke from the OSS.
