Advantages of single toggle jaw crusher shanghai principles

jaw crusher working principleit will be noted that the motion is a rocking one. when the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire upstroke. a reversal of this motion occurs during the downstroke of the eccentric. see full list on 911metallurgist the horizontal component of motion (throw) at the discharge point of the singletoggle jaw crusher is greater than the throw of the dodge crusher at that pointin fact, it is about threefourths that of blake machines of similar shortside receivingopening dimensions. the combination of favorable crushing angle, and non choking jaw plates, used in this machine, promotes a much freer action through the choke zone than that in the dodge crusher. capacities compare very favourably with comparable sizes of the blake machine with nonchoking plates, and permissible discharge settings are finer. a table of ratings is given. see full list on 911metallurgist the singletoggle type jaw crusher has been developed extensively. because of its simplicity, light weight, moderate cost, and good capacity, it has found quite a wide field of application in portable crushing rigs. it also fits into the small, singlestage mining operation much better than the slower dodge type. some years since, this type was developed with very wide openings for reduction crushing applications, but it was not able to seriously challenge the gyratory in this field, especially when the highspeed modern versions of the latter type were introduced. see full list on 911metallurgist within the limits of its capacity, and size of receiving openings, it is admirably suited for such operations. small gravel plant operations are also suited to this type of crusher, although it should not be used where the gravel deposit contains extremely hard boulders. the crusher is easy to adjust, and, in common with most machines of the jaw type, is a simple crusher to maintain. in spite of their similarities, each crusher design has its own limitations and advantages that differ from the other one. a gyratory crusher can be fed from two sides and is able to handle ore that tends to slab. its design allows a higher speed motor with a higher reduction ratio between the motor and the crushing surface. this means a dollar saving in energy costs. a jaw crusher on the other hand requires an ely wheel to store energy. the box frame construction of this type of crusher also allows it to handle tougher ore. this design restricts the feeding of the crusher to one side only. when a machine has such a reputation for excellence that buyers have confidence in its ability to justify its purchase, it must be good! take the type g traylor jaw crusher, for instance. the engineers and operators of many great mining companies know from satisfying experience that this machine delivers a full measure of service and yields extra profits. so they specify it in full confidence and the purchase is made without the usual reluctance to lay out good money for a new machine. the success of the type g traylor jaw crusher is due to several characteristics. it is (1) strong almost to superfluity, being built of steel throughoutit is (2) foolproof, being provided with our patented safety device which prevents breakage due to tramp iron or other causes of jammingit is (3) economical to operate and maintain, being fitted with our wellknown patented bulldog pitman and toggle system, which saves power and wear by minimizing frictionpower that is employed to deliver increased productionit is (4) convenient to transport and erect in crowded or not easily accessible locations, because it is sectionalized to meet highly restrictive conditions. see full list on 911metallurgist as rock particles are compressed between the inclined faces of the mantle and concaves there is a tendency for them to slip upward. slippage occurs in all crushers, even in ideal conditions. only the particles weight and the friction between it and the crusher surfaces counteract this tendency. in particular, very hard rock tends to slip upward rather than break. choke feeding this kind of material can overload the motor, leaving no option but to regulate the feed. smaller particles, which weigh less, and harder particles, which are more resistant to breakage, will tend to slip more. anything that reduces friction, such as spray water or feed moisture, will promote slippage. see full list on 911metallurgist a jaw crusher size is obtained by looking at its feed opening (gape) and length. as an example a monster 7959 of 79 x 59 (2m x 1.5m) will have its fixed jaws 79 apart where the feed enters on a 59 wide set of liner plates. the primary rock breaker that is most commonly used in small plants is a jaw crusher of the blake type, a typical section of which is shown in fig. 4. see full list on 911metallurgist the jaw crusher discharge opening is the distance from the valley between corrugations on one jaw to the top of the mating corrugation on the other jaw. the crusher discharge opening governs the size of finished material produced by the crusher. see full list on 911metallurgist to compensate for wear on toggle plate, toggle seat, pitman toggle seat and jaws additional shims must be inserted to maintain the same crusher opening. the setting adjustment system is designed to compensate for jaw plate wear and to change the css (closed side setting) of the jaw crusher. the setting adjustment system is built into the back frame end. see full list on 911metallurgist is done considering the maximum rocklump or large stone expected to be crushed and also includes the tph tonnage rate needing to be crushed. in sizing, we not that jaw crushers will only have around 75% availability and extra sizing should permit this downtime. see full list on 911metallurgist it will be seen that the pitman (226) is suspended from an eccentric on the flywheel shaft and consequently moves up and down as the latter revolves, forcing the toggle plates outwards at each revolution. the seating (234) of the rear toggle plate (239) is fixed to the crusher frame the bottom of the swing jaw (214) is therefore pushed forward each time the pitman rises, a tension rod (245) fitted with a spring (247) being used to bring it back as the pitman falls. thus at each revolution of the flywheel the movable jaw crushes any lump of ore once against the stationary jaw (212) allowing it to fall as it swings back on the return halfstroke, until eventually the pieces have been broken small enough to drop out. it follows that the size to which the ore is crushed. see full list on 911metallurgist the jaw crusher is not so efficient a machine as the gyratory crusher described in the next paragraph, the chief reason for this being that its crushing action is confined to the forward stroke of the jaw only, whereas the gyratory crusher does useful work during the whole of its revolution. in addition, the jaw crusher cannot be chokefed, as can the other machine, with the result that it is difficult to keep it working at its full capacity that is, at maximum efficiency. see full list on 911metallurgist tables 5 and 6 give particulars of different sizes of jaw crushers. the capacity figures are based on ore weighing 100 lb. per cubic foot for a heavier ore the figures should be increased in direct proportion to its weight in pounds per cubic foot. see full list on 911metallurgist the jaw crusher gets its name from the type of crushing surface used. this surface is literally two jaws. one of which is a stationary or fixed jaw. the other is called a swing jaw. see full list on 911metallurgist these jaw crushers are ideal for small properties and they are of the high capacity forced feed design. on this first forced feed jaw crusher, the main frame and bumper are cast of special alloy iron and the initial cost is low. the frame is ribbed both vertically and horizontally to give maximum strength with minimum weight. the bumper is ruggedly constructed to withstand tremendous shock loads. steel bumper can be furnished if desired. the side bearings are bronzethe bumper bearings are of the antifriction type. this bearing arrangement adds both strength and ease of movement. the jaw plates and cheek plates are reversible and are of the best grade manganese steel. the jaw opening is controlled by the position of an adjustable wedge block. the crusher is usually driven by a vtov belt drive, but it can be arranged for either vtoflat or fiat belt drive. the 8x10 size utilizes a split frame and may be packed for muleback transportation. cast steel frames can be furnished to obtain maximum durability. see full list on 911metallurgist this second type of forced feed rock crusher is similar in design to the type h listed above except for having a frame and bumper made of cast steel. this steel construction makes the unit lighter per unit of size, and adds considerable strength. the bearings are all of special designthey are bronze and will stand continuous service without any danger of failure. the jaw and cheek plates are manganese steeland are completely reversible, thus adding to their wearing life. the jaw opening is controlled by the position of an adjustable wedge block. the crushers are usually driven by vtov but can be arranged for vtoflat and belt drive. the 5x6 size and the 8x10 size can be made with sectionalized frame for muleback transportation. this crusher is ideal for strenuous conditions. consider a multi jaw crusher. see full list on 911metallurgist whenever mining man need a crusher that is thoroughly reliable and big producer (which is of all time) they almost invariably think first of a traylor type g jaw crusher. by experience they know that this machine has built into it the four essentials to satisfaction and profit strength, foolproofness, economy and convenience. see full list on 911metallurgist analysis of the single toggle jaw crusher force transmission this paper sets out to perform a static force analysis of the single toggle jaw crusher mechanism and to obtain the force transmission characteristics of the mechanism. in order to obtain force transmission metrics that are characteristic of the structure of the mechanism, such influences as friction, dead weight, and inertia are considered to be extraneous and neglected. equations are obtained by considering the balance of forces at the moving joints and appropriately relating these to the input torque and the output torque. a mechanical advantage, the corresponding transmitted torque, and the variations thereof, during the cycle of motion of the mechanism, are obtained. the mechanical advantage that characterizes the mechanism is calculated as the mean value over the active crushing stroke of the mechanism. the force transmission characteristics can be used as criteria for the comparison of different jaw crusher mechanism designs in order to select the most suitable design for a g see full list on hindawi the literature on kinematics and mechanism design identifies three tasks for which linkage mechanisms are commonly designed and used, namely, function generation, motion generation, which is also known as rigid body guidance, and path generation [1 1. a. g. erdman and g. n. sandor, mechanism design: analysis and synthesis, vol. 1, prenticehall, 1991. see in references 3 1. j. e. shigley and j. j. uicker jr., theory of machines and mechanisms, mcgrawhill book company, 1980. see in references ]. way back in 1955, freudenstein, who is widely regarded as the father of modern kinematics of mechanisms and machines, introduced an analytical method for the design of a fourbar planar mechanism for function generation [4 1. f. freudenstein, approximate synthesis of four bar linkages, transactions of the asme, vol. 77, pp. 853861, 1955. view at: google scholarmathscinet see in references ]. wang et al. presented a study on the synthesis of planar linkage mechanisms for rigid body guid see full list on hindawi over time, several authors have addressed the static force analysis of the double toggle jaw crusher mechanism. among the earlier of such efforts is that of ham et al. [10 1. c. w. ham, e. j. crane, and w. l. rogers, mechanics of machinery, mcgrawhill book company, 4th edition, 1958. see in references ], who performed a static force analysis of the double toggle jaw crusher mechanism in order to determine the input turning moment that would be required to overcome a known crushing resistance of the material being crushed. they used a graphical method to carry out the analysis. in discussing linkages, martin [11 1. g. h. martin, kinematics and dynamics of machines, mcgrawhill, 2nd edition, 1982. see in references ] featured the double toggle jaw crusher mechanism as an example of a machine that uses the toggle effect to obtain a large output force that acts through a short distance, but he did not perform a static force analysis of the mechanism. erdman and sandor [1 1. a. g. erdma see full list on hindawi according to ham et al. [10 1. c. w. ham, e. j. crane, and w. l. rogers, mechanics of machinery, mcgrawhill book company, 4th edition, 1958. see in references ], analysis of forces in any machine is based on the fundamental principle which states that the system composed of all external forces and all the inertia forces that act upon any given member of the machine is a system that is in equilibrium. for a planar mechanism, such as the single toggle jaw crusher, it is customary to treat the forces as if they are coplanar, at least in the initial analysis. the effects of the offsets between the planes of action of the forces can then be revisited at a later stage of analysis and design. the assumption of coplanar forces will be employed in this presentation. in the static force analysis of a machine, the forces arising due to the accelerations of the machine members are neglected. these forces are taken into account in a dynamic force analysis, which can be done, meaningfully, aft see full list on hindawi in the kinematical model of the single toggle jaw crusher, which is illustrated in figure 1, the eccentric shaft is modelled as a short crank, of length , that continuously rotates about a fixed axis, at . the swing jaw is modelled as the coupler link , of length , which moves with a complex planar motion that has both rotational and translational components. the toggle link is modelled as the rocker , which oscillates about the fixed axis at . the fixed jaw is considered to be an integral part of the frame of the machine. oduori et al. [19 1. m. f. oduori, s. m. mutuli, and d. m. munyasi, analysis of the single toggle jaw crusher kinematics, journal of engineering, design and technology, vol. 13, no. 2, pp. 213239, 2015. view at: publisher sitegoogle scholar see in references ] analysed the kinematics of the single toggle jaw crusher, as modelled in figure 1, and found the following expression:cao et al. [20 1. j. cao, x. rong, and s. yang, jaw plate kinematical analysis for see full list on hindawi the forces and moments acting upon the links of the single toggle jaw crusher mechanism are all assumed to be coplanar and illustrated in figure 2. in performing the static force analysis it shall be assumed that the masses of the links, as well as friction forces, are negligible. the effects of these forces can be considered at a later stage in the design of the mechanism. in figure 2, is the driving torque, applied at the crank axis , to drive the crank and the entire crusher mechanism. is the torque, acting about the axis of joint , due to the resistance of the feed material against being crushed. , , and are the forces in links 2, 3, and 4, respectively, and they are all assumed to be compressive. the system of forces and moments is assumed to be in equilibrium in every phase of motion of the mechanism. see full list on hindawi the forces acting at the moving joints and are shown in figure 3. let us start by considering the crank. static force analysis is based on the assumption that there are no accelerations in the mechanism. referring to figures 1, 2, and 3, the equilibrium of moments acting on the crank, about the fixed joint , leads to the following result:next let us consider the coupler. the equilibrium of forces at joint leads to the following:from equations (5) and (6), it follows thatthe statement in equation (7) is illustrated in figure 4. moreover, it should be evident from figures 3 and 4 thatnow, in figure 3, by considering the equilibrium of all the forces acting upon the coupler, the following is obtained:moreover, in figure 3, the equilibrium of moments acting on the coupler, about the joint , leads to the following result:from equations (9) and (10), it follows thata relationship between and can now be obtained from equations (7) and (11), as follows:equation (12) is in dimensionless form see full list on hindawi in the preceding section, we have seen that the crushing stroke lasts for only about 50% of each complete cycle of motion of the single toggle jaw crusher. for the other 50% of the complete cycle of motion, the swing jaw is being retracted in preparation for the next crushing stroke. moreover, in figure 5, it can be seen that the force transmission ratio varies from a very high value, at the beginning of the crushing stroke, that initially falls very rapidly and then levels off to reach a minimum value of less that unity (about 0.6), about halfway through the crushing stroke. the latter half of the crushing stroke appears to be a mirror image of the earlier half, in which the force transmission ratio first rises gradually and then spikes to a very high value at the end of the crushing stroke. sample values of the force transmission ratio during the useful crushing stroke are given in table 2. the fact that the crushing stroke commences with a very high value of the force transmissio see full list on hindawi a static force analysis of the single toggle jaw crusher mechanism was carried out. the method used is systematic, clear, and simple to follow and to use. as a result of the static force analysis, some force transmission characteristics of the single toggle jaw crusher mechanism were obtained. the analysis can also be used to determine the forces that are sustained by each of the components of the single toggle jaw crusher mechanism, provided that the values of the input torque and load torque are known. an expression for the force transmission ratio of the single toggle jaw crusher mechanism was derived. by using the dimensional data of the pe 400 by 600 jaw crusher, the maximum value of the force transmission ratio was found to be about 3268, the minimum value of the force transmission ratio was found to be about 0.61, and the mean value of the force transmission ratio was found to be about 10.6. these metrics can be used as criteria in the selection of a suitable mechanism design see
