OSS is the largest discharge opening dimension on the jaw It is equal to the CSS plus the throw of the swing stock 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 Eccentric shaft is one of the main vulnerable parts of jaw crusher If jaw crusher fails to work caused by abrasive eccentric shaft users would have no idea because they learn little about the maintenance and repairment of jaw crusher Today Mining Machinery tech you how to repair the eccentric shaft of jaw crusher

Jaw Crushers

Jaw Crushers – When Only the Most Massive Rugged and Cost-Effective Jaw Crusher in the Industry Will Do! infoterrasource The massive cast steel pitman and forged alloy steel eccentric shaft are supported by four anti-friction roller bearings Applications Employed as a primary crusher the overhead eccentric jaw

Jaw crusher parts that contain frame movable and stationary plate bearing eccentric shaft toggle jaw flywheel eccentric shaft belt pulley back-moving spring jaw plate crusher parts Solid and durable property JXSC the crushers machine with a non-welded frame has been proved that it has outstanding solid and durable strength All the

The electric motor drives eccentric shaft to move via pulley and belt which makes movable jaw move back and forth according to the predetermined track Material is extruded rolled and crushed after entering the crushing chamber Crushed material would be discharged through bottom discharge mouth

The jaw crusher was not functioning properly for the crushing operation but the flywheel continued to turn The cause of the problem Jaw crusher eccentric shaft pull rod device damaged resulting in the loss of support of toggle plate

Jaw Crusher Flywheel Rotational energy is fed into the jaw crusher eccentric shaft by means of a sheave pulley which usually has multiple V-belt grooves In addition to turning the pitman eccentric shaft it usually has a substantial mass to help maintain rotational inertia as the jaw crushes material Jaw Crusher Tension Rod

What is a Jaw Crusher?

A jaw crusher's flywheel toggle plates pitman eccentric shaft and driving motor generate the crushing action and provide the energy needed to break the material There are some different styles of Jaw Crushers the most common being the overhead eccentric jaw (shown above) or a double toggle jaw

Through transmission of belts the motor drives the eccentric shaft Under drive of the eccentric shaft the moving jaw does periodic motion towards the fixed jaw When the space between the moving jaw and the fixed jaw reduces the materials will be crushed When the space between the moving jaw and the fixed increases the final crushed

When the small jaw crusher working belt and belt pulley are driven by a motor The movable jaw moves up and down via eccentric shaft The angle between fixed jaw and movable jaw becomes smaller when the moving jaw runs down then the materials are crushed into pieces It becomes bigger when the movable jaw runs up

The moving plate is pivoted at the top end (Blake crusher) or at the bottom end (Dodge-type crusher) and connected to an eccentric shaft In universal crushers the plates are pivoted in the middle so that both the top and the bottom ends can move The Stag jaw crusher shown in Figure 2 4 has a fixed jaw and a moving jaw pivoted at the top

Working Principle Of PE Jaw Crusher Motor-driven belt and pulley through the eccentric shaft to move the jaw up and down movement when moving jaw rises between toggle plate and moving jaw angle between large thus promoting the moving jaw plate close to the fixed jaw plate simultaneously with the material being crushed or split pieces to achieve the purpose of crushing when moving jaw down

Jaw Crusher Features A very large eccentric shaft forging and four large high-quality spherical roller bearings Solid structure accurate manufacturing and assembling guarantee the durability 3Optimized design enables convenience in use High quality parts and materials have been applied

A stone crusher machine is designed to reduce large rocks into smaller and more manageable particles Crusher uses mechanical pressure for breaking of an ore or rock Just like human jaw it engulfs a feed to crush into more digestible output or th

JAW CRUSHER With their excellent engineering and high-quality manufacturing Meka jaw crushers simplify your life Mo4) steel eccentric shaft The larger eccentricity of pitman shaft provides a motion that pulls the material to the bottom of the jaw plate Spherical self-aligning roller bearings straight-bore pitman bearings and tapered


The Blake type jaw crusher has a fixed feed area and a variable discharge area Blake crushers are of two types- single toggle and double toggle jaw crushers 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

Nov 02 2008Jaw breakers use an eccentric shaft to make the jaw move an inch and a half at around 400 rpm That makes 1500 engine rpm with a 540 rpm PTO So i dont know if it will be direct drive with just a torsion damper to get maximum fuel efficiency or with a 1 1 25 reduction so the tractor engine can run at 1900 to 2000 rpm to get more power

When movable jaw pushes the movable jaw plate to move towards the fixed jaw plate materials are squeezed rolled and crushed When the movable jaw and movable jaw plate move backward under the action of eccentric shaft and spring previously broken materials are discharged from the bottom discharge mouth of the crushing chamber

Dec 09 2014• Jaw Crusher • Jaw crusher is a type of crusher which produces coarse particle • Feed size of the jaw crusher is 1500mm-40mm and the product size is from 50mm-5mm • Compressive strength of jaw crushers is 320 mega Pascal • Rpm for jaw crusher is between 200- 400 6

Jaw crusher is made up with rack seesaw side guard eccentric shaft and transmission The eccentric shaft made of high carbon steel is the core part of the jaw crusher and has a large bending torque The seesaw simulates the two movements of the animal to complete the material crushing operation 2 High production capacity
