3 Jaw Crushers 12 4 Cone Crushers 20 5 Roll Crushers 23 6 Low Speed Sizers 26 7 Horizontal Shaft Impactors 29 To control top size from a single crusher operating in an open circuit, material must remain in crusher at a setting which produces a satisfactory feed size for the secondary crusher and
May 13, 2019· Additionally, jaw crusher feed should be pre-screened using a grizzly screen prior to crushing to remove material finer than the closed-side setting. Setting jaw crushers. Ideally, the reduction ratio of a jaw crusher should be 6-to-1. There are different ways to calculate reduction ratio, but the best way is something called the P80 factor.
Open Side Setting Maximum distance between jaw die for a given setting (this is the distance when the jaw is at rest) Some designs of jaw crushers require wedges to ensure that the jaw plates are held firmly in position. These are also a wear part that can be replaced when worn down.
Crusher Operation What is the Closed Side Setting (CSS)?-Minimum gap setting of when the mantle bowl rotates within the crusher or moving plate is closest to the fixed plate in a jaw crusher (‘closed’ position) - Gyratory’s: typically 90 to 220mm-Secondary’s: typically 30-60mm-Tertiary’s/Scats: typically 8-20mm-Jaw Crushers: 80-150mm
The opening of the primary crusher, for example, will affect the throughput of secondary crushing, and secondary crushing will, in turn, influence tertiary production and so on. How to check the opening of the jaw crusher Whenever a jaw crusher is off and at rest (stopped), it will remain in the open position at its open-side setting (OSS).
The automatic hydraulic toggle has greatly reduced the time it takes to change a jaw crusher’s setting. As jaw dies wear, the hydraulic toggle can be easily adjusted to maintain a constant closed side setting while in continuous operation. An added benefit of the Lippmann hydraulic toggle package is the ability to provide tramp release once
The set of a crusher can be varied in the field and some crushers are equipped with automatically controlled actuated for the automatic control of theThe throw of the crusher is the distance that Figure 5.1 Schematic diagram of a crusher showingg the open- and closed-side settings. moving jaw

Check that the jaw die and key/heel bolts are tight. Check that the discharge area is free of buildup. Also, check the discharge setting on the jaw crusher and inspect the toggle plate for cracks. Listen for any knocking sound from the toggle while the crusher is running empty, and adjust the toggle as needed.
Jaw crushers jaw crushers are mainly used as primary crushers their main purpose is to reduce the material to a small enough size that it can be transported by conveyors to the next crushing stages the eccentricity causes the cone head to oscillate between open side setting and closed side setting discharge opening.
The widest distance is known as the open side setting (OSS) and the narrowest, the closed side setting (CSS). These settings are important. The OSS is the largest distance between the concave and the mantle at the bottom of the crusher, so it determines the largest particle size of the outgoing product.
Apr 15, 2013· jaw crusher problems, maintenance, jaw closed side setting. jaw crusher is one of the most widely used primary crushing machine in mining, quarrying, aggregate … aggregates plant set up – Crusher South Africa
Jan 17, 2016· 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. Closed side setting (CSS) The closed side setting can be calculated by deducting the stroke from the OSS.
OPEN SIDE SETTING Maximum distance between jaw plates for a given setting. (this is the distance when the jaw is at rest) CLOSE SIDE SETTING Minimum distance between jaw plates derived from the OSS and the stroke. DRIVE SIDE Side of the crusher fitted with a grooved pulley couple to the crusher drive. NON DRIVE SIDE
