Jaw Crushers typically have a reduction ratio of 6:1, which means a 30" feed will be reduced down to 5" at the smallest size. The product size can be adjusted by opening or closing the gap between the jaw dies at the smallest point. This is referred to as the closed-side setting.
Here, we will provide methods for adjusting the gap size of jaw crusher and the equipment used. The common ways to adjust jaw crusher gap are toggle plate adjustment, gasket adjustment and wedge adjustment.
February 6, 2024. 2:39 pm. The Essential Role of Jaw Crushers in Ore Processing. Jaw crushers are truly the bedrock of any material processing work in both the mining and construction worlds.
Adjusting and Measuring Jaw Crushers. The jaw crusher diagram is instrumental when it comes to adjustments for altering the granularity of the output. One critical metric is the Closed Side Setting (CSS)—the smallest gap between the jaws during the crushing cycle.
A jaw crusher has a wider range of settings—generally, a maximum of two to three times the smallest setting. The tables also show that for a comparable maximum size of feed and setting, a gyratory crusher has a much greater capacity than a jaw crusher.
The CSS (Closed Side Setting) of a jaw crusher is the gap between the two jaw plates in the closed position. Adjusting the CSS is crucial for controlling product size and ensuring the desired outcome.
Shim-adjust Jaw Crushers employ the use of shims to change the closed-side setting, while hydraulic Jaw Crushers rely on hydraulics to make changes with the push of a button. Additionally, hydraulic Jaw Crushers offer automatic tramp metal relief and automatic chamber clearing in the event of a power surge or failure.
While older-style crushers require time and labor to change settings via a manual shim adjustment, modern crushers are easier to manage with two ways to make setting adjustments.
A jaw crusher size is obtained by looking at its feed opening (gape) and length. As an example, a monster 7959 of 79″ x 59″ (2m x 1.5m) will have its fixed jaws 79″ apart where the feed enters on a 59″ wide set of liner plates. The factors list below will enhance crusher capacity and performance: 1.
