Stone crusher machine divides into a mining crusher and a medical crusher. The mining crusher equipment divides into jaw crusher, gyratory crusher, impact crusher, cone crusher, hammer crushers, roller crushing, mobile crusher, etc. according to the principle of crushing. Jaw crusher for sale

Gyratory crusher is a new type of crusher which can replace fine jaw crusher or cone crusher. The gyratory crushing equipment has a bright future in the mineral processing market. Its working part is a high-speed rotary crushing roller, which is coupled with a pair of curved crushing plates arranged symmetrically on the left and the right to form two optimal crushing cavities for the pliers. Under the action of the eccentricity of the main shaft, the crushing roller makes a transverse rotary motion. And make it produce strong cyclic extrusion pressure, continuous progressive on the two crushing cavities of the material alternately broken. Then the product from the two discharge mouth constantly discharge.

The primary gyratory crusher breaks the material by feeding mouth into the two rollers between the extrusion crushing, finished materials naturally fall. In case of too hard or can not be broken, the roller crusher by hydraulic cylinder or the role of the spring can automatically retreat. So that the gap between the rollers increase, too hard or can not break down, so as to protect the machine from damage. The opposite two rollers have a certain gap, change the gap, you can control the product maximum discharge granularity. Rotary crusher is the use of a pair of opposite rotation of the round roll. Four-roll crusher is the use of two pairs of opposite rotation of the round roll crushing operations.

JXSC tooth roller crusher mainly uses the special wear-resistant tooth roller high speed rotation to crack the material (the traditional tooth roller crusher uses the low speed extrusion crushing) , has formed the high productivity mechanism. The roller crusher with saw teeth on the surface of both rollers mainly plays the role of cracking and tearing, and also has the role of crushing, grinding and crushing. The broken teeth arranges in a spiral shape. The small particles in the feed are easily discharged through the gap between the broken rollers. The big pieces are broken by the shearing and tensile force of the teeth. The situation that the material is broken without control in the traditional crusher is improved.

The good effect of fine crushing 1. There are cracks and other weak spots or defects in almost any particle. The double-cavity gyratory crushing, because of the multi-directional pressure on the material, under the interaction of multi-layer material, makes the material easier to be broken from the defect. Then it can obtain high crushing rate and produce more fine-grained products. 2. Due to Lamination crushing, even with a larger outlet, a finer product and a finer product size distribution can be obtained. 3. The high-frequency swing crushing roller can break the material more times than the traditional crusher in the crushing chamber, so the size of the discharging material is a greatly reduce. The production practice shows that when the size of the feed is 80 mm, the content of 12 mm can reach 80 %, and the content of 6 mm can reach 50%.

1. Double-chamber gyratory crusher is a crusher machine that continues working with a double-chamber. The crusher equipment changes the discontinuous working mode of single chamber of jaw crusher. 2. The characterize is that producing more fine products under the condition of larger discharge port. Under the premise of ensuring fine products, the larger discharge port can obviously have more processing capacity.

Small work vibration Gyratory crusher has no supporting structure of the elbow plate. The crushing roller works in a balanced rotary state. So the vibration is small and the noise is low. It can work smoothly on the steel frame without foundation.

1. When double cavity rotary crusher machine crushing materials, the roller swing movement. The crushing force mainly occurs near the eccentric position of the crushing roller, forming high power density crushing. Then forming the crushing process with the circular movement of the eccentric position of the crushing roller. Because the crushing force concentrates on a small amount of material in a section of the crushing chamber, the crushing force uses in the operation is smaller and the energy utilization rate is high. Therefore, it has obvious energy-saving effect. 2. The crushing machine continuous working, which can make full use of the output energy of the driving motor. And it can make use of the strong kinetic energy of debris splashing produced in the process of rock crushing to carry out the re-crushing of the adjacent rocks. Repurposing the secondary energy. 3. As fully utilize the energy, the production practice has proved that the electricity consumption per ton of ore processing is generally 0.5 degrees.

1. The double chamber rotary crusher works smoothly on the steel frame without foundation. Then civil construction is easier and installation is more convenient. 2. The crusher machine parts are all used expansion sleeve connection. So it is very convenient to disassemble and assemble, repeated disassembly will not affect the assembly accuracy of the machine. 3. Easy adjustment of discharge opening and simple structure. 4. Only use grease lubrication, management, and maintenance of convenient, low cost.

1. The two cone shapes of the gyratory crusher are steeply inclined. The movable cone is upright, and the fixed cone is an inverted truncated cone which in order to increase the need for feeding ore. Nevertheless, cone crusher has two cone shapes, which are gently inclined, vertical frustum cone. There is a certain length of parallel ore crushing area (parallel belt) between the two cones which in order to control the requirement of mineral product granularity. Because of the medium and fine crusher, and coarse crusher different. It is to crush product quality and production capacity as the primary consideration.

4. The gyratory stone crusher changes the size of the ore discharge port is using to adjust the rise or fall of movable cone. Cone crushers adjust the height of the fixed cone to realize theadjust of the width of the ore discharge mouth.

gyratory vs jaw crushers: advantages & disadvantages

gyratory vs jaw crushers: advantages & disadvantages

Nodiscussion of primary crusher selection would be complete without a comparison of the two leading types: the standard gyratory crusher and the Blake jaw crusher. Although their fields of application overlap to a considerable degree (at least in the realm of primary crushing) there is no real conflict between these two machines; one supplements the other and, between them they very effectively cover an imposingly large proportion of the entire field of primary crushing applications. This does not mean that other types, such as the sledging rolls, for example, are not better suited for certain applications; but there are very few primary crushing jobs to which the gyratory or jaw crushers, or both of them cannot be applied with at least a fair degree of satisfaction.

Either of the two types can be built to handle the hardest and toughest rock or ore that can be economically mined or quarried. The jaw crusher, because of its box-frame construction, and simple toggle mechanism, is especially well adapted to extra heavy design for the crushing of extremely tough materials: in this respect it holds some advantage over the gyratory type, because the extra strength necessary for such work can be built into it at less cost than is required for the gyratory with its more complex shell castings. However, cases where extreme brute strength enters into the selection problem are relatively rare, either type can be used for the great majority of materials encountered in crushing practice, either in standard form or in reinforced design. Strengthening of these machines for extra-heavy duty follows certain well established practices which have been proven to be necessary or desirable. Usually it is a matter of selecting stronger metals, or adding weight in the frame, or both; seldom is it necessary to change the proportions of the working mechanism.

In most cases selection of one type or the other can be made on the basis of performance characteristics, receiving openings, space requirements, and so forth, without regard to relative strength of design. In choosing between the two for any specific application it is helpful to have a list of the salient features of each type, in a form that will permit quick and easy comparison. The following lists emphasize the favourable characteristics of each machine.

Neither machine is particularly well suited to handling very soft, or mushy materials, although the jaw crusher is superior to the gyratory for such service. Loosely cemented minerals, such as soft sandstone, will not work well in the gyratory crusher; packing on the diaphragm behind the pipe is almost certain to cause trouble. The jaw crusher will handle rock of this character if it is reasonably free-flowing. The action on all very soft materials is inclined to be sluggish and, unless it is at the same time of a free-flowing nature, packing in the crushing chamber is an ever present hazard. The jaw crusher will handle rock and ore containing a considerable proportion of loam, or similar contamination, provided that the admixture is not so viscous that it builds up on the jaw plates. The gyratory should never be used for materials containing more than a small percentage of such contamination, the allowable amount being that which the clean crushed rock will keep scoured off of the diaphragm. Flushing the diaphragm will prevent packing of this dirty material, but this practice is usually not permissible in the crushing plant.

We have had occasion to use the expression, comparable sizes, a number of times in this work, with reference to comparisons between two types of crushers, particularly the jaw and gyratory types. This expression has been used by many writers on the subject; usually without any attempt to define exactly what it implies. As a matter of fact, it is a difficult term to define with any degree of accuracy. The Old Quarryman says, It means two machines, one of which you would buy if you didnt buy the other one, providing you had enough money to buy either one of them. That comes about as near as any definition. Comparable sizes of gyratory and jaw crushers are those sizes which the engineer or operator pairs off against each other when making a selection to fit his specific problem, and these pairings may not be the same for all problems. One job may involve capacity as the most important factor; the next one may demand special emphasis on receiving opening. Obviously these different requirements may call for setting up acomparison between different sizes of one or the other type.

Usually, in selecting the primary crusher, receiving opening is the prime consideration; admitting of course that capacity must be adequate. The following list is an attempt to pair off gyratory and jaw crushers on the basis of effective receiving openings, bearing in mind that each shape of opening has its advantages for certain shape-characteristics of the feed, as has been pointed out.

Sometimes, in making a comparison of receiving openings, it is helpful to make a scale drawing of both openings, superimposing one upon the other. The rectangular jaw opening is simple and easy to layout. To draw the gyratory opening, it is necessary to know the top diameter of the crushing head; to make a complete sketch, the diameter of the spider hub and the width of the spider arms should also be known, but this information is not absolutely essential in making the comparison. Taking half the top diameter of the head as a radius, draw the circle which represents the top of the head; then, increasing the radius by the actual opening between head and concaves at their tops, draw the circle representing the concave ring at the top of the crushing chamber. Then superimpose the diagram of the jaw crusher opening, laying it in tangent to the head circle.

To facilitate this work for the line of Superior McCully gyratory crushers, we list in the following table the top diameters of the heads, and openings between head and concaves for straight-face, and non-choking, concaves.

Laying in the plan view of the spider hub and arms will, of course, give a more complete picture of the gyratory crusher receiving openings, but the picture is likely to be a littlemisleading unless it is borne in mind that the maximum diameter of the spider hub is some distance above the upper rim of the crushing chamber, and therefore does not restrict the receiving opening as much as the plan view indicates. The true effective receiving opening can only beshown in its proper proportions by tilting the plan view; that is, by an angular projection normal to a plane which is tangent to the bulge of the spider hub, and to the top of the crushing head, To draw such a view requires more information, and usually more drafting skill, than the average man has at his disposal. The circle method described in the second preceding paragraph is sufficiently close for all practical purposes.

If the material to be crushed is of a slabby nature, for example, a thinly stratified limestone or shale; the product of the jaw crusher is certain to contain slabs, some of which may be quite large, particularly so if some of the strata in the deposit are thinner than the discharge setting of the crusher. Nor is this tendency to slab in the crusher confined to stone of stratified formation. Some rocks of massive formation may contain parallel cleavage planes in certain sections of the deposit. Such material will slab in the crusher just the same as those rocks which wereformed in definite layers, or beds.

The gyratory crusher by virtue of its annular discharge opening is an effective slab breaker. This faculty, coupled with the fact that its receiving openings are especially well suited for admitting slabby feed, give it a very definite advantage over the jaw crusher in the handling of such material. In the foregoing comparison of these two leading types of primary breakers we have endeavoured to present the case for each of them in a fair and impartial manner. It would be difficult, and probably more than a little tedious for the reader, if we were to attempt a more definitive analysis or to set up fixed rules of procedure for selecting one or the other machine; a process which is always fraught with pitfalls in such a broad and empirical branch of engineering as the processing of rocks and ores. Usually the matter of choice can quickly be narrowed down to a comparison of one size in each type. These two machines may then be tabulated with respect to capital investment, capacity, power requirements, space requirements, and so forth; their receiving openings may be compared, as we have suggested, and all of the factors we have discussed in this section checked against the features and limitations of each machine to determine its ability, or inability, to fit into the plan.

During the using process, if the worker operates and maintains the crusher according to correct standards, it will have great significance in normal production, output, quality, service life, working efficiency and the prevention of accidents, etc.

At present, the common cone crushers are mainly the single toggle cone crusher and compound cone crusher (Symons cone crusher). Although both types of cone crushers are totally different, they have the same operation procedure.

The operation procedure of cone crusher can be divided into four stages: before the start, at start-up, at run time and turning-off time. All conditions should be paid attention in each stage, and the potential problems can be found and solved timely and the service time can be prolonged.

Turn on the lubricating oil pump to run for three to five minutes. After everything runs well, turn on the crusher as required. After the crusher idles for one to two minutes, confirm that all things are well, and feed the rocks or stones.

During the crushing process, there is a great impact on the concave which makes the filled zinc layer be out of shape. Therefore, the U-type bolt should be tightened frequently to make the concave fix and avoid concave from deformation.

The mantle is fixed by the upper bolt of the main shaft. The looseness of the bolt can make the mantle unstable, even the filled layer may fall off to cause downtime. Hence, the bolts should be often checked and fixed to avoid looseness.

The spherical bearing should be installed in the borehole of crusher closely. After a long period of working, the tightness of crusher' parts can be broken. The tightness of spherical bearing must be checked frequently, and the oil gallery of the spherical bearing should be kept clean.

Water seal is the equipment for preventing crusher from dust, which is very important to the normal operation of cone crusher. Therefore, daily maintenance and checking its integrality are very necessary.

Through the study of this article, you must have a deeper understanding of the operation and maintenance of the cone crusher. In the case of the above-mentioned failure of the crusher, the problem is analyzed and solved by referring to the method given in this article.
