5 ·A jaw crusher is generally used as a primary and secondary crusher in a crushing plant Material is fed into the top of the jaw crusher by vibrating grizzly feeder The crushes are driven by overhead eccentric shafts seated in spherical self aligning roller bearings
For crushing middle hard to hard and abrasive materials in primary and secondary crushing applications for low and high capacities Single toggle jaw crushers are characterized by the swing jaw being suspended directly on the eccentric drive shaft and the lower part of the swing jaw being braced against the crusher frame by means of a toggle plate
The swing jaw is activated by an eccentric main shaft which lifts and thrusts the swing jaw towards the fixed jaw thus creating the crushing action The crusher discharge setting CSS is variable by mechanical shim adjustment of the swing jaw behind the toggle plate
While the single toggle jaw crusher is used for most of the applications the double toggle jaw crusher is only used in very special hard rock requirements ERC ® Eccentric Roll Crusher ERC ® The Eccentric Roll Crusher is our innovative and unique machine for primary crushing It can be described as a combination of a Jaw Crusher and
·A jaw crusher is a robust essential and rugged crusher used primarily in mining and construction for the initial crushing of large rocks and ore The fixed jaw stays put while the movable jaw powered by an eccentric shaft moves in a reciprocating motion This motion brings the movable jaw closer to the fixed jaw crushing the material
2 ·Jaw crushers are mainly used as primary crushers in mining construction materials infrastructure and other sectors As the start of a high productivity crushing line using high quality replacement parts is crucial to extending the jaw crusher s service life and crushing effect
·18 • Single Toggle Jaw Crusher • In the single toggle jaw crushers the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher • The swing jaw suspended on the eccentric undergoes two types of motion swing motion towards the fixed jaw due to the action of toggle plate and vertical
·Jaw Crusher Spare Parts Regular Inspection Conduct routine inspections of all components including jaw plates bearings eccentric shaft and toggle plate to identify and address issues early Lubrication Keep all moving parts well lubricated to reduce friction and wear Follow the manufacturer s recommendations for the type and
·&the eccentric shaft Single toggle jaw crusher Double toggle jaw crusher The characteristics of this type of crusher are as following 1 Larger rough blocky as well as sticky rock or ore lumps can be crushed View metadata citation and similar papers at brought to you by CORE
·Jaw Crushers are used to reduce the size of many different types of materials in many applications The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double toggle Jaw Crusher Introduced in 1906 McLanahan s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers
·design the crusher for improved performance Jaw crusher structure diagram shown in figure 6 requirement for the Figure 6 Single toggle jaw crusher & jaw crusher structure The breakage force is measured in the experiment and some new information on the material flow in jaw crusher chamber is illustrated with the particle
·The eccentric shaft is positioned behind the swing jaw and the toggle plates connect the lower part of the swing jaw to the drive mechanism As the eccentric shaft rotates it drives the toggle plates to move creating a powerful crushing action as the angle between the two toggles becomes more acute
·Unlike the Blake Jaw Crusher the Dodge Jaw Crusher has a movable jaw that moves back and forth like a pendulum while the fixed jaw remains in a stationary position As the material is fed into the crushing chamber it is crushed by the movement of the movable jaw against the fixed jaw
3 ·The jaw crusher reduces the size of stones and ores by squeezing which is able to accept large size raw materials and is usually used for primary crushing Typical features of a jaw crusher are its two large flywheels and the V shaped jaws in the The movable jaw assembly and heavy duty eccentric shaft are forged from high end materials for
·Rotational energy is fed into the jaw crusher eccentric shaft by means of grooved pulley which usuall y has multiple V belt grooves designed in such a way that they hav e approximately equal weight;
·All data should be used as a guide only and are not guaranteed They depend on the feed material characteristics and the actual crusher configuration B A D E C 1 Crusher capacity calculated based on a typical run of mine feed material with an average raw density t/m³ and max feed size ≤ 80 % of crusher feed opening
·Jaw crusher movement is guided by pivoting one end of the swinging jaw and an eccentric motion located at the opposite end [4] The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws For instance a 22 x 30 jaw crusher has an opening of 22" by 30" a 46 x 46 jaw crusher has a opening of 46" square
·Although jaw rock crusher is usually used in the primary crushing stage in the crushing production line And the PEX series jaw crusher machine can also be used in the secondary crushing and fine crushing stages The motor of the single toggle jaw crusher drives the eccentric shaft to rotate through the belt and pulley The movable jaw
Dodge Jaw Crusher Similar to the Blake crusher the Dodge crusher has a movable jaw that moves towards and away from the stationary jaw and is preferred for crushing softer particles Universal Jaw Crusher This type has a V aligned fixed jaw and a movable jaw on an eccentric shaft creating an elliptical motion
The materials used to manufacture spare and wear parts play a key role in the performance and ultimate success of your Trio® jaw crusher Manganese steel has been used in crusher wear parts for decades because of its work hardening properties As rocks meet the outer layer of the manganese steel its exterior layer hardens
·Jaw crusher is mainly used in the industries of metallurgy mining chemical cement construction refractory materials and ceramics suitable to crush hard and soft ores with compressive strength less than 320 MPa This machine can break material s into Jaw crusher mainly consists of frame eccentric shaft jaw plate connecting bar
·The cheek plates are located on either side of the jaw crusher and are used to crush material against the stationary jaw They are typically made of manganese steel or another hard material and are subjected to a great deal of stress and strain during operation In conclusion the main parts of a jaw crusher include the frame the eccentric
Crusher body forms a single welded box holding all parts of the crusher on Feeding chute allows material to be fed without The pulleys made of GG 22 steel casting are connected to the motor with a belt pulley system creating the drive of the Pitman made of GS 52 casting forms the movable jaw of the crusher and provides crushing of the material by
