Single toggle jaw crusher. Single Toggle Jaw crushers are used for primary crushing. … The motor transmits power to the ...
The main shaft is eccentric and on this eccentric shaft is mounted the movable jaw, imparting a rotary movement to the jaw. This rotary movement followed by the movable jaw actually pushes the feed down into the crusher, as well as crushing. From this action is derived the name "Forced Feed."
The jaw crusher eccentric shaft is typically constructed using 30Mn5 casting steel for its strength and durability. At Qiming Casting, we have collaborated with several local foundries to produce and design a wide range of high-quality, eccentric shafts for various types and brands of jaw crushers. These components are widely used in quarries ...

drive to the eccentric shaft of the roll. This is generating the oscillating motion of the freely rotatable roll with constant large stroke in the entire crushing cavity. Consequently, the crushing gap between the roll and the jaw in the crusher housing changes constantly and the feed material which has not been screened out is
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.

Jaw crusher is one of the important crushing equipment in mining industry. It has the incomparable advantage of stable and reliable operation, easy maintenance, long service life, less dust and noise. Eccentric shaft, the main drive part plays an important role in the operation process.
The moving jaw closes against a stationary jaw with sufficient force to fracture material, usually rock of some type. This crushing action is accomplished as a result of eccentric motion developed by a pitman, or eccentric shaft. Motor power is applied to the crusher drive shaft, which in turn transfers rotation to the eccentric shaft.
Flywheel hubs of our jaw crushers are equipped with special locking assembly which connects flywheels to the eccentric shaft. This system ensures that the flywheel is held safely and tightly on the shaft. This feature is important as the crusher has to be brought into operation under load, resulting from unforeseen stoppages.
