The size of a jaw crusher is measured by the top opening of the crushing chamber. For example, a 48" x 42" jaw crusher measures 48" from one crushing jaw to another and is 42" across the width of the two crushers. The primary applications for using jaw crushers are: Crushing different kinds of ore; Reducing building rubble to pieces
The dimension on the discharge end of the jaw liners are measured from Peak to Root. To measure the discharge dimension, lock out the crusher. Check the arrow on the flywheel as this will identify the position of the eccentric shaft. When the arrow points upward then the measured value at the discharge end of the jaw liners will be the CSS.
Measurement of the crusher's closed side setting varies depending on the jaw profile that is being used and has an impact on the crusher's capacity and product gradation. The following factors will enhance crusher capacity and performance: 1.roper selection of the jaws. P 2. Proper feed gradation. 3. Controlled feed rate. 4.
The jaw crusher above is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.
Crusher Vision is an automated system for determining closed-side setting (CSS) in a gyratory crusher by measuring the gap between the concave and mantle, as shown in Fig. 1.
