Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.Web

These crushers were manufactured by Brothers Company of Milwaukee. The cone crusher transformed the linear motions of the jaw crusher into a combination of circular and eccentric motion. The moving jaw was replaced by a cone (which gives the machine its name). The cone is supported and driven by an axle which …Web

the jaw can be quite small, since complete crushing is not performed in one stroke. The inertia required to crush the material is provided by a weighted flywheel that moves a shaft creating an eccentric motion that causes the closing of the gap. Single and double toggle jaw crushers are constructed of heavy duty fabricatedWeb

The primary coal crushers may be of different types such as: (1) coal jaw, (2) coal hammer, and (3) ring granulator. Secondary coal crusher: Used when the coal coming from the supplier is large enough to be handled by a single crusher. The primary crusher converts the feed size to one that is acceptable to the secondary crusher.Web

The crushing force is generated by the two jaws, one of which is fixed, while the other reciprocates. The stationary vertical jaw is called fixed jaw, while the reciprocating jaw is known as swing jaw. The swing jaw moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever as shown in Fig. 6.8. The gap ...Web

A jaw crusher essentially crushes large rocks to a more usable size. They're typically the first-line machinery used in the material reduction for several applications. This includes rock quarries, sand and …Web

In some crushers, like the C105™ and C3055™, the jaw die design on the ends is different. The locking wedges on these crushers are located behind the jaw dies rather than at the top of the jaw die. The jaw dies can be allowed to wear until the thickness is 60-65 mm thick or the teeth are worn flat.Web

Jaw crushers are so powerful that they've earned the moniker "rock breakers" because of their brute force. All jaw crushers will have one fixed jaw and a moving one. These two form a V-shaped chamber, where the materials are fed. The movable jaw will move back and forth against the fixed one, compressing all materials in …Web

Generally gyratory crushers, jaw crushers, high speed double roll crushers, low speed sizers, impactors and hammer mills are used as primary crushers. In the secondary and subsequent stages, the material is further reduced and refined for proper size and shape, mostly based on specifications. Most secondary crushers are cone crushers andWeb
