The Bond work index (Bond, 1960) is based on Bond's law, which states that the energy consumed is proportional to the 1.5 power of particle size rather than the square of Rittinger's law. ... For operating a jaw crusher it is necessary to know the maximum power required consistently with the reduction ratio and the gape and closed side ...
The single-toggle jaw crusher has less shafts and bearings compared to double-toggle jaw crushers. Only one toggle goes from the bottom of the swinging jaw back to the fixed point. Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down.
A material is crushed in a Blake jaw crusher such that the average size of particle is reduced from 50 mm to 10 mm with the consumption of energy of 13.0 kW/(kg/s). Determine the consumption of energy needed to crush the same material of average size 75 mm to an average size of 25 mm using (i) Law of Rittinger (ii) Law of Kick (ii) Law of …
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 …
How To Use A Jaw Crusher? If you want to use a jaw crusher to crush rocks or other materials, there are a few key things that you should keep in mind. First, you will need to carefully select the jaw plates so that they can effectively crush your chosen material. Second, you should ensure that the jaw plates fit snugly into the crusher's jaw.
trial jaw crushers was analyzed using the proposed equation in combination with that of Bond (1961) for calculating the energy requirement in size reduction. The equation for capacity The volumeof material (V) that passes through the crusher bottom opening per stroke is given by: If the machine is run at low speeds, the movement of the

Bond's equation for energy consumption in comminution, a method was developed to analyze the performance of indus trial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have sufficient installed power to operate at full capacity. The
By using the data of E.A. Hersam and F.C. Bond's equation for energy consumption in comminution, a method was developed to analyze the performance of industrial jaw crushers. The study showed that industrial jaw crushers are generally operated below capacity. The study also showed that industrial jaw crushers generally have sufficient …

It can be written in the following form: Wi = W/ (10/√P – 10√F)………………………………………………………….. (1a) The work index Wi can be determined from plant operations and from laboratory …
Reduction of data from one type or size of jaw crusher into the equivalent performance of another crusher has been accomplished by ratios of all of the various equation factors involved. The individual u Fig. 3-Dodge-type jaw crusher showing relative swing jaw motion at feed and discharge ends.
A jaw crusher operates by the movement of a movable jaw in relation to a fixed one to crush large rocks into smaller pieces. It does this by using a spinning shaft that makes the movable jaw move back and forth. When the movable jaw goes towards the fixed jaw, it squishes the stuff in between and breaks it into smaller bits. ...

The Dodge-Jaw Crusher : In the Dodge Crusher, the moving jaw is pivoted at the bottom. The minimum movement is thus at the bottom and a more uniform product is obtained. However this type of crusher is not commonly used due to its tendency to choke. The larger opening at the top enables it to take very large feed and to effect a large size ...
Jaw Crusher adalah rahang yang dapat digerakkan atau diayunkan dan digerakkan untuk mendekat dan mundur secara bergantian dari rahang tetap. ... which is the process of releasing ore minerals from their bonds which are gangue minerals. Comminution or size reduction is the initial stage in the PBG (excavated material processing) process which ...

Strength and fracture toughness of the material to be crushed are intrinsic properties that determine the time and energy required to crush the material. Economy of the crushing process is partly dependent on the angle of nip. Productivity of …
The jaw crusher (Figure 4.1) In a jaw crusher, feed is admitted between two jaws, a stationary jaw or anvil and a movable jaw, which reciprocates in a horizontal plane. It makes an angle of 20 - 30o with the stationary jaw. It is driven by an eccentric so that it applies great compressive force on the lumps caught between the jaws.
