Jaw crushers reduce large rocks or ore by means of compression. mechanical pressure is applied using the crushers two jaw one is fixed while the other makes an eccentric movement. there are also primary and secondary types of these crushers. jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds.
Crushers may be divided into three general classes, with respect to the manner in which they do their work pressure crushers this category embraces the several types of gyratory crushers and jaw crushers, as well as the double crushing rolls, with either smooth or corrugated shells. impact crushers this division is represented chiefly by the various styles.

Fig.3 shows the configuration of the jaw crusher and geometrical and operation parameters are given in table 1. jaw crusher mainly, consist of moving jaw, eccentric shaft, flywheel and toggle plate. the jaw has specific motion to break feed material by the means of eccentric shaft. while jaw width is 1100 mm, gaps from upper side is 650 mm.
Their simplicity requires little engineering expertise to operate.aw crusher is reliable and needs less maintenance than other types of crushers.aw crusher has one fixed and one moving surface inshaped configuration. the moving jaw is mounted on an eccentric shaft.
Eccentric movement of the crusher main shaft. it is the back and front to and fro movement of the moveable jaw stock that gives the tremendous crushing force to each stroke. the moveable jaw stock comprises of the grease drum and the part where the high.
Furthermore, the crushers described above and illustrated in the drawings have the crusher head 12 journalled to the eccentric outer surface of the eccentric 10, 11, whereas the shaftxtends along the main axisf the crusher, so that the eccentric rotates about the shaftnd appliesyratory movement to the crusher head 12. the.
5 the eccentric shaft is not properly heattreated and the stress is concentrated, causinghortterm fracture. solutionseplace the new eccentric shaft and lift the main frame correctly.eplace the new eccentric shaft and select the appropriate crusher according to the compressive strength of the crushed material.
Ture shaft rotation must be equal to the free fall of the jaw crushers is its capacity. the capacity depends on the number of revolutions of the eccentric shaft withimple motion of the moving jaw. the crusher achieves the maximum capacity at.
Inypical jaw crusher, two outer bearings located on either side of the main frame support an eccentric shaft, while two inner bearings supportovable jaw. these are commonly known as pitman bearings. the reciprocating motion of the shaft.
Structure of jaw crusher mainly include frame, eccentric shaft, big pulley, flywheel, moving jaw, side guard plate, toggle plate, toggle plate back seat, adjusting screw gap, the reset spring, fixed jaw plate and movable jaw etc.he toggle plate also playole as insurance bracketorking part of jaw crusher is two pieces of jaw plate.
Crusher,jaw crusher and impact crusher. our objective is to design various components of an impact crusher like drive mechanism, shaft, rotor ,hammers, casing ,feed and discharge mechanism which will be useful in minimizing weight, cost and maximizing the capacity. impact crushers they involve the use of impact rather than pressure to crush.
There are two main groups of jaw crushers, categorized according to their jaw movement mechanism. singletoggle jaw crushers doubletoggle jaw crushers. in singletoggle jaw crushers, the movable jaw is supported by the bearing on an eccentric shaft driven by the pitman to which it is attached.
How doesock crusher work the working principle of jaw rock crushers for sale is when the stone crushing equipment works, motor drives belt and pulley to move, and the eccentric shaft drives the mobile jaw plate. when the mobile jaw plate rises, the angle between elbow plate and mobile jaw plate becomes larger.
Introduced in 1906, mclanahans universal jaw crusher was one of the first modern era overhead eccentric jaw crushers. on the overhead eccentric style jaw crusher, the moving swing jaw is suspended on the eccentric shaft with heavyduty double roll spherical roller bearings. the swing jaw undergoes two types of motion one iswing motion.
The gyratory crusher shown in figure 2.6 employsrushing head, in the form ofruncated cone, mounted onhaft, the upper end of which is held inlexible bearing, whilst the lower end is driven eccentrically so as to describeircle. the crushing action takes place round the whole of the cone and, since the maximum movement is at the bottom, the characteristics of.
Eccentric bushing in the eccentric bearingia the countershaft assembly h. this rotating eccentric bushing imparts an eccentric motion to the main shaft b,haracteristic of the gyratory crusher. in this way the crushing gap located between the fixed concaves in the crusher shell and the eccentrically gyrating mantle continu.
Gyratory crusher components. the gyratory crusher is made up of six main componentsase, main frame and concave liners, drive assembly, mantle, spider arm assembly, oil system. the base is the section of the crusher that provides an entry point for the drive assembly and oil system. it also provides support for the working surface of the.
