Advantages of design mechanical engineering jaw crusher

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 s 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 jaw crusher design mechanical engineering hp in tn1,2,3department of mechanical engineering 1,2noble engineering college,
