Like the jaw crusher, the cone crusher provides a relatively low cost crushing solution, but there are application drawbacks that may make another crushing solution more appealing. First, cone crushers cannot accept all material sizes. Any material fed to the crusher must be pre-sized for that particular crusher (usually 200mm or less).
A single toggle Blake jaw crusher with 22.8 cm x 47.7 cm receiving hopper crushed gold ore at the rate of 85 t/h with closed setting at 2.54 cm and maximum opening of 3.8 cm. The work index of the ore was 13.5 kWh/t.
The jaw crusher above is designed for the motor sizes listed in RPG and technical specifications. This means that for harder materials, the crusher will have to be operated at larger settings to avoid overload of drive and/or motor. Using oversized motors will lead to radically shorter crusher life and various mechanical problems.
The Blake crusher in common with all machines of the jaw family is built into a rectangular frame, at one end of which is located the crushing chamber; in fact, the end of the box-frame constitutes the stationary jaw. The movable or swing jaw is suspended from a cross-shaft (swing jaw shaft) at its upper end, this shaft in turn being supported ...
crushing work index of 16. Factors that markedly affect results are: • Structure of material • Compressive strength or crushing work index of material • Grading of crusher feed • Degree of pre-scalping • Choke versus irregular or low rate of feed The table requires careful interpretation for particular
Starting from the base working principle that compression is the forcing of two surfaces towards one another to crush the material caught between them.Impact crushing can be of two variations: gravity and dynamic. An example of gravity impact …

Work Index of 16. Factors that markedly affect results are: • Structure of material • Compressive Strength or Crushing Work Index of material • Grading of crusher feed • Degree of pre-scalping • Choke versus irregular or low rate of feed We are pleased to examine specific applications and advise on the likely results from our machines.
These parameters include rock's Work Index, crusher reduction ratio, jaw plate dimensions, material's compressive strength, and ore fracture toughness. These parameters analyse the jaw crusher's deformation and warping. Therefore, there is a dire need to incorporate several parameters in the design of these machines to increase their …
The JW Series of Single Toggle Jaw Crushers is designed with a tight crushing chamber nip angle and an aggressive crushing stroke to maximise productivity. The …
Take jaw plate as example, some jaw plate is MN13, some is Mn18%. different stone of MOH is different including how many working hour the crusher does everyday. The standard can only be determined through the material being crushed, as the abrasive nature will be the main variable in determining wear.
The work index includes the friction in the crusher and the power given by above eq is gross power PROCEDURE: • Start the jaw crusher and find the power consumption under no load condition with the help of energy meter and a stop watch. • Prepare the sample you want to crush in the jaw crusher.
the crusher and scalp out fi nes. Primary gyratory crushers – ideally suited to all high-capacity primary hard rock crushing applications. Jaw crushers – we have more installed jaw crushers than anyone in the world. The lead-ing choice due to their high reduction ratio and heavy duty design. Cone crushers – capacities available to suit all
Taking into account the limitations present in this research work, here a jaw crusher simulation is presented. The jaw crusher design parameters selected are the ones found by the SGA optimization scheme. ... Bond work index theory represents an average value on size reduction and energy usage per unit of mass, but represents a fair ...
The moving jaw rotates around the eccentric axis as well as swings around the same center (Fig. 2).By removing the moving jaw suspension shaft and the front toggle plate of simple pendulum jaw crusher, and suspending the moving jaw on eccentric shaft to combine the connecting rod and the moving jaw into whole, a compound pendulum …
The Finlay® J-1175 Tracked Jaw Crusher is a high performance and aggressive mobile crusher. Incorporating a ® Jaques JW42 jaw crusher and a heavy duty vibrating grizzly feeder, the Finlay® J-1175 gives optimum production in a range of applications.
In a jaw crusher, the material is crushed between two plates: a static plate and a moving plate. Compression is applied by the moving plate, and the material becomes crushed. ... (2014). In their study, energy was estimated with the Bond work index, and an on-line optimization algorithm was used to increase the efficiency of a laboratory ...
WEBThe only correction factor that might affect the calculation is to correct for the efficiency of the motor -- the work index is based on motor output (pinion) power, whereas the …
For a selected optimised case an attempt was made to simulate the jaw crusher using a commercial software for discrete element modelling (DEM), after first simulating single particle breakage using this software. ... This approach implies the measurement of variations in the Bond Work index values during the pre-treatment of …
The JW Series of single toggle jaw crushers is designed with a tight crushing chamber nip angle and an aggressive crushing stroke to maximize productivity. The accompanying …
Thus, the equipment having the highest indices, and hence the largest energy consumers, are found to be jaw and gyratory crushers and tumbling mills; intermediate consumers …
