A Jaw Crusher is sized so that the maximum feed size is 80% of the gape and width openings. The gape is the measurement between the two jaw dies, while the width is the measurement between the two side plates. For example, if the maximum feed size is 29"x49", the crusher gape would be 32" and the width would be 54".

Therefore, you must consider the hardness and toughness of the jaw plate when you want to choose a correct one. These jaw crusher plates are deliveried to Indonesia If the hardness of the jaw …
All jaw crushers are rated according to their receiving areas, i.e. the width of the plates and the gape, which is the distance between the jaws at the feed opening. For example, 500x750mm jaw crusher has a width of 500 mm and a gape of 750 mm. Cross-section through double-toggle crusher. Consider a large piece of rock falling into the mouth of ...
The basic technology behind jaw crushers has been around for almost 200 years, although it has undergone all manner of refinements and improvements to make it more efficient and more reliable. The main operating principle of a jaw crusher is the combination of fixed and moving jaw plates, between which material is crushed as force is applied to it.
Jaw crusher and cone crusher are usually arranged on the stone crusher plant in two stages. Jaw crusher breaks the rock to 10 ~ 30 cm size. Cone crushing machine further broke the stone to below 10 cm. Large cone crushers (gyratory crushers) also can as head crushers. Fine jaw crusher also can as a two-stage crusher, crushing stone to cm …
Adjusting and Measuring Jaw Crushers. The jaw crusher diagram is instrumental when it comes to adjustments for altering the granularity of the output. One critical metric is the Closed Side Setting (CSS)—the smallest gap between the jaws …
Disadvantages of Using a Jaw Crusher. One of the main disadvantages of using a jaw crusher is that it can be difficult to control the size of the output material. The size of the output material is determined by the distance between the two jaws, and this distance cannot be easily adjusted. Additionally, jaw crushers can generate a lot of dust ...
Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...
The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate.

Working Principal of Jaw Crusher. Lumpy test material to be crushed is fed into the crushing zone through a hopper. The crushing zone consists of two parallel side walls of hardened and tempered steel and two special profile Jaws. One jaw is provided with oscillatory motion, whereas the other jaw is hinged to adjust the gap and get desired ...
Double Toggle Jaw Crusher. In contrast, the single toggle jaw crusher has fewer shafts and bearings and only one toggle which goes from the bottom of the swinging jaw to a fixed point at the back of the jaw crusher. The eccentric is located at the top of the swinging jaw and is part of the shaft. The advantage of this is that the jaw has two ...
Before assembly, check it carefully, and then use the crane to place the rod bolt slightly lower than its normal position in the crusher. Wash the upper and lower bearings of the rod bolt and lubricate them with thin oil, and then install the bearing, main shaft, upper bearing, and upper shell. Lifting the rod bolt, then install the bolts and ...
Straight Jaw Plates: A shows a diagram of a standard type of Blake crusher with regular or straight jaw plates. This type of plate has been the standard from the time of its inception, emulating, in this respect, the straight concaves in the gyratory machine. And it will be noted that the theoretical action in this straight-plate ...
For example, in a typical jaw crusher, the length of the jaw plate may range from around 24 to 36 inches, and the width may range from around 12 to 16 inches. The thickness of the jaw plate may vary from around 1 to 2 inches, depending on the material being crushed and the specific application.
The jaw crusher is the first choice for primary crushing in the crushing production line. Whether it is the aggregate production line or the sand production line, jaw stone crushers are inseparable. ... you can increase or decrease the number of gaskets and change the total thickness. So the front and rear position of the toggle plate changes ...

Introduction: Jaw crushers are powerful machines that are widely used in the mining, quarrying, and recycling industries. These machines are designed to crush large rocks and ores into smaller pieces for further processing. A jaw crusher consists of a fixed jaw and a movable jaw, with the latter being driven by an eccentric shaft that moves the …
Cone crusher basics in 4 minutes. This is the starting point for understanding how cone crushers work – and how they can make your mine or quarry more productive. Elsewhere on the site you can find detailed information about all aspects of crushing and screening, but to make sense of these it helps to understand the basics of cone crushing.
Jaw Crusher Reduction Ratio. Either an 8-to-1 or 6-to-1 ratio should be the target reduction ratio for maximum jaw crusher efficiency. This setting typically provides an ideal P80 factor—when 80% of crushed material produced by primary crushing will pass screening after processing. A smaller closed-side setting will produce more fines.
Jaw crushers are the most common solution in underground applications when the throughput is below 1000 tonnes per hour, depending somewhat on the scalping solutions. Above 1000 tph, primary gyratory crushers are an option. After the throughput reaches 2000 tph, jaw crushers are very rare, with the exception of a parallel plant layout.
Introduction: In the world of material processing and mining, Jaw Crushers stand as stalwart machines, pivotal in breaking down large rocks into more manageable sizes. One of the leading names in ...
The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.

And the width of the toggle plate is considered at 100, 400,800, It is observed that as the width of the toggle plate increases Von Misses stress as well as displacements in the structure increases.
