VELOCITY OF THE ECCENTRIC SHAFT OF JAW CRUSHERS Fig 1 shows a drawing of a jaw crusher with an eccentric shaft When the moving jaw is removed from the static [4] the crushed product is freely discharged through the disharge port of the crusher under its own weight With each move of the jaw only ore pieces located below the level
— Jaw crusher is a kind of size reduction machine that is wide utilized in mineral aggregates and metallurgy fields The interaction between jaw plates and material particles brings the inevitable and high wear to the jaw plates throughout the jaw crusher operation that not only decreases the efficiency however also will increase the price and also the energy consumption of the jaw

The Sandvik 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
Jaw crusher bekerja dengan mengandalkan kekuatan elektromotor Daya dari elektromotor di transmisikan ke eccentric shaft pada frame jaw crusher melalui sabuk karet vbelt Gerakan berputar eccentric shaft diubah menjadi gerakan maju mundur swing jaw
The dependences of the angles of the rotation of the link on the angle of the eccentric shaft rotation of the crusher were obtained which allowed determining the trajectories of different points
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
It should be noticed that the values for throwing the moving jaw are calculated by the equation 26 [3] and based on catalog data [4] related to the number of revolutions and the size of discharge with 24 √ From where it follows that √ 25 n0 optimum speed of eccentric shaft Rpm g acceleration due to the gravity m/s2 α
eccentric shaft polished to a fine finish and with no screw threads or sharp radii that can cause stress concentrations Constant shaft alignment Self aligning spherical roller bearings Even distribution of crushing forces Machined jaw face locations Protection of swing jaw holder and main frame jaw locations

the jaw crusher can crush rocks efficiently through the entirety of the cavity and the nip angle can be further improved with an intermediate plate Nordberg C Series jaw crushers 7 The setting of the Nordberg C Series jaw crusher can be adjusted with two wedges without shim plates The adjustment system is
The paper analyzes forces acting on a piece of raw material in a jaw crusher with a simple motion of the moving jaw and based on this defines the formula to define the optimal number of revolutions the eccentric shaft Under the optimum number of revolution the eccentric shaft the number of revolutions is assumed to ensure that the crusher achieves the maximum crushing
Purpose To obtain equations that can be used to describe the motion of any given point in the swing jaw of a single toggle jaw crusher Design/methodology/approach The swing jaw drive mechanism
