Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end.  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.
2 Crusher Bearings: Knowing the Basics Leads to Better Care Compression Crushers In compression crushers, high start-up torque, shock loads and vibration demand high-performing anti-friction bearings that can operate reliably with minimal heat generation. Jaw Crushers Most operations prefer jaw crushers for primary crushing. A large feed
Design of Jaw Crushers Jaw crushers are designed to impart an impact on a rock particle placed between a fixed and a moving plate (jaw). The faces of the plates are made of hardened steel. Both plates could be flat or the fixed plate flat and the moving plate convex.

In one respect, the working principle and application of this machine is .
Due to their simple design and easy maintainability jaw crushers are widely used as primary size reduction equipment in mechanical and mining industries. As jaw crushers break minerals & ores of high strength and the economy of many industries depends on its performance; it is essential to improve the efficiency of the present design.
In order to optimize bearing life, only tapered roller bearings are used in Lippmann jaw crushers. The tapered bearings offer a combination of features that spherical bearings are unable to provide.
Jaw crushers typically use spherical roller bearings, which support radial loads and misalignment. These bearings also operate under moderate speeds and loads, with occasional load spikes. Cone “gyratory” crushers: In a cone crusher, the main shaft is housed in a frame attached to a mantle.
Minyu Jaw Crushers are configured for primary crushing of the hardest rock. Incoming material is crushed between the jaw crusher’s fixed die plate and movable die plate through advancing and retreating motions of the jaw crusher pitman arm. The Jaw Crusher main shaft bearing includes a dust seal with oil bath lubrication.
92 Double toggle jaw crusher Double toggle jaw crushers have a large mouth open-ing. They are used, for example, as primary crushers to prepare ballast for road building. The coarse crushing is followed by further crushing operations until an ag-gregate of the size and shape required, e.g. gravel or grit, is obtained. Operating data
• Radial thrust tapered roller bearings, the best design for absorbing and withstanding shock, radial and thrust loads. • Longer jaw length to provide increased crushing area, steeper nip angle and increased capacity. • Curved jaw dies to provide non-choking crushing action, reversible for increased wear.
Eagle Jaw Crusher: Additional Features. Processes abrasive hard rock, using the time tested overhead eccentric design. The short bearing span between the side frames reduces stress and shaft deflection.

All sizes incorporate a fixed jaw die configuration with a wrap-around design that protects the crusher frame. Easy-to-maintain cheek plate bolt system. Crushers are driven by extra large, overhead eccentric shafts seated in closely-spaced spherical, self-aligning roller bearings.
4. The bearing design ensures the big loading capacity and reliable operation of jaw crusher. 5. The design of toggle plate increases the stroke of lower chamber and processing capacity. 6. The integrated design of the motor base together with the main frame saves the installation space. 7.
The Lippmann Milwaukee jaw has longer jaw dies, a larger eccentric and a non-choking design. The longer jaws also mean a reduction in nip angle, resulting in a more positive bite. The Lippmann Milwaukee jaw can also have a smaller discharge setting than other crushers allowing for a higher degree of flexibility with related equipment.
