hammer crusher vs jaw crusher which is better (7 tips) mamp;cjaw crusher is often used as the coarse crushing equipment of aggregate production line, followed by impact crusher or cone crusher, and then added sand making machine (shaping machine) for shaping. 7. which is better, hammer crusher or jaw crusher. the main advantage of hammer crusher is that the ore with low hardness can be formed in one time. hammer crusher crushing machineshammer crusher is a mechanical machine intended for crushing pieces, grains and particles of mineral raw materials and similar matters under the action of impact forces of crusher hammers pivotally mounted on a rapidly rotating rotor, as well as reaction forces of corresponding breaker plates located on the crusher casing. hammer crusher eastman rock crusherwearresisting hammer head the hammer head of the hammer crusher is the main vulnerable parts. in view of this shortage, our hammer head adopts highquality high manganese steel, and after strict heat treatment, a single austenite structure, service life than the ordinary manganese steel is more than five times higher, the efficiency of more than 30%. hammer mill crusher ampgrinderthe hammer mill is the best known and by far the most widely used crushing device employing the impact principle of breaking and grinding stone. thus far we have described machines which do a portion of their work by impact, but the only machine described in which this action plays an important role was the sledging roll type and particularly the edison roll crusher and in these machines impact is supplemented to a substantial degree by a positive and powerful sledging action by teeth which are rigidly attached to massive rolls. in the hammermill, impact is the predominating action although its scope varies in different designs of this machine, as will be seen. see full list on 911metallurgist hammermills may be connected directly to the driving motor, or driven by a flat belt or vbelts. the two latter methods have one material advantage over the direct drivethey permit speed adjustments to achieve optimum performance for each particular set of conditions. belts also affords a substantial cushioning effect between mill and motor when tramp iron or broken hammers throw heavy shock loads upon the driving apparatus. see full list on 911metallurgist speed, or velocity, while it is the very life of the hammermill, may also function to limit the amount of feed that the mill will take. thus, in any given machine, the number of rows of hammers used will affect capacity. or, to state it a little more clearly, for any combination of speed, feed size, and number of rows of hammers there is a definite limit to the amount of material that the mill will receive. see full list on 911metallurgist this is understandable when it is considered, for example, that in a machine running 1500 rpm, with four rows of hammers, the receiving opening is swept by a row of hammers 100 times each second, and there is obviously a limit to the amount of material that can enter the space between two successive hammer rows in this short period of time. we find that for some combinations of feed size and product size, more production can be obtained with only two rows of hammers, rather than three, or more. radial velocity of the material entering the mill will naturally have a direct bearing upon the amount that will drop in between the rows of hammers. thus, in a well designed mill the feed spout is always so arranged that the material falls, rather than flows, into the crushing zone. see full list on 911metallurgist it is hardly necessary to state that the size of product directly affects the capacity of a hammermill, just as it does any type of crusher. the finer the product the more work the machine must dofurthermore, the grate bars, when any are used, must be spaced closer, which means that the open area of the grate section is reduced. see full list on 911metallurgist size of feed affects capacity, but not always in the inverse proportion which might, at first thought appear to be logical. for example, suppose we were operating a mediumsize hammermill on limestone, turning out a 10mesh product. we know that this machine will handle more tonnage if we feed it with, say, 3 maximum size rock, as compared with a feed of 10 or 12 maximum sizewhich accords with the logical expectation. however, if we further reduce the feed size to, say 12 maximum, we find that our will increase very little if at allin fact it may actually decrease. this apparent anomaly is explained by the fact that the effect of impact upon a free body of material varies directly with the mass of the bodyconsequently the energy absorption, and hence the shattering effect, is much greater on the 3 piece than it is on the 1/2 particle. see full list on 911metallurgist because all these variables that we have noted have an influence upon the capacity of the hammermill, it is impossible to present a comprehensive tabulation of capacity ratings which can be relied upon for any and all materials. we can however do so for any one material, as we did for the fairmount crusher. it is convenient and logical that this should be a medium limestone in this case also, because hammermills are applied extensively to crushing, and pulverizing, that kind of rock. above is the approximate capacity ratings of the various sizes of hammermill (impact crushers), on medium limestone, and for various grate bar spacings. unless the prospective hammermill user has operational data on which to predicate his selection of a new machine for some specific service, the safest procedure is to have his material tested, either in the field or in the laboratory, in a mill of the type he proposes to install. see full list on 911metallurgist the shattering effect of the blows delivered by hammers travelling at velocities as high as 200 feet/second is conducive to both of these results. it is natural to expect that gradation of the hammermill product would vary somewhat for materials of differing friability, and results verify this expectation. furthermore, speed has a definite influence upon product gradationhigh speeds increase fines, and vice versa. the effect of impact at extremely high speed is, on friable material, almost explosive, the action being more aptly designated as pulverizing, rather than crushing. lower impact velocities have a more moderate breaking effect, and if the material is able to clear the crushing chamber before it is struck too many times, the low speed hammermill will turn out a fairly uniformly graded product on material of average friability. see full list on 911metallurgist what is intended to take place inside a hammermill is the uniform, efficient reduction of the material introduced into the grinding chamber. this particle reduction occurs as a result of the impact between a rapidly moving hammer and a relatively slow moving particle. if sufficient energy is transferred during the collision, the particle breaks and is accelerated towards the screen. depending on the particle size and the angle of approach, it either passes through the screen or rebounds from the screen into the rapidly moving hammers again. as materials move through the grinding chamber they tend to approach hammer tip speed. since reduction only occurs when a significant energy is transferred from the hammer to the particle (large difference in velocities), less grinding takes place when the particles approach hammer tip speed. many manufacturers incorporate devices within their mills to interrupt this product flow, allowing impact and reduction to continue. tear circle hammermills have a more positive, natural redirection of product at the inlet than full circle design machines. while the basic operational concepts are the same for all hammermills, the actual unit operating conditions change rather dramatically depending on the materials being processed. grains such as corn, wheat, sorghum and various soft stocks, like soybean meal, tend to be friable and easy to grind. fibrous, oily, or high moisture products, like screenings, animal proteins, and grains like oats and barley, on the other hand, are very tough and require much more energy to reduce. consequently, the hammermill setup that works well for one will not necessarily work for the other. the following discussion covers such factors as tip speeds, hammer patters and position, horsepower ratios (to hammer and screen area), and air assist systems. little space is devoted to screen sizes (perforation or hole size) since processing variables would make any hard and fast statements nearly impossible. see full list on 911metallurgist this machine operates on the principle of reducing the material by striking it while in suspension, as opposed to attrition. the material is fed into the top of the machine and falls into the path of the rapidly revolving hammers. different degrees of reduction may be had by simply varying the speed of the machine. see full list on 911metallurgist this unit is of extra heavy construction and consequently is well adapted for severe duty. the hinged breaker plate is adjustable while operating and is fitted with a heavy renewable liner. shafting is high carbon forged steel and is fitted with discs which are of heavy plate and cast steel, carefully balanced. screen bars may be high carbon steel, tool steel, or manganese steel as desired. jeffrey swing hammer pulverizers have heavy cast iron frames and are lined with renewable chilled iron liners. hammers are made of materials best suited for the particular job. highest grade radial ball bearings are used and they are readily accessible for inspection and oiling. this keeps power consumption to a minimum and maintenance and repair part costs are extremely low, even for most types of heavy duty. see full list on
