hammer mill crusher & grinder

hammer mill crusher & grinder

The 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.

The hammermill, fundamentally, is a simple mechanism. The orthodox machine comprises a box-like frame, or housing, a centrally disposed, horizontal-shaft rotating element (rotor) on which the hammers are mounted, and usually a set of circumferentially arranged grates in the lower part of the housing. The rotor consists of a shaft carried in bearings at either side of the housing, and the hammer centre of multi-flange drum or spool shape. The flanges of this drum-like assembly are drilled near their outer edges for hinge pins to which the inner ends of the hammers or hammer arms are attached. The hammers themselves are made in a variety of styles and shapes. Sometimes the hammer arm and head are cast, or forged, integrally; in other designs as in the impactorthe arms and hammer head are separate pieces.

The grates usually consist of a transversely arranged series of tapered, wear-resisting steel bars, which form a cage of circular cross section across the lower part of the housing just below the hammer path. The spacing of these steel bars varies quite widely, depending upon the size of product and upon the characteristics of the material to be crushed. The spacing may be anything from % in. or slightly less, up to several inches, and in some machines may be dispensed with entirely for coarse products and closed-circuit operation.

Hammermills may be connected directly to the driving motor, or driven by a flat belt or V-belts. The two latter methods have one material advantage over the direct drive; they permit speed adjustments to achieve optimum performance for each particular set of conditions.

In the impact-hammer-mill, a cross-sectional view of which is shown here on the left,the process is, in one important respect, a reversal of that just described. The material enters the machine on the up-running side of the rotor, where it is struck by the hammers as they start their sweep across the upper part of the housing. The top of the crushing chamber is lined with a series of breaker plates whose impact faces are involute with respect to the hammer circle, so that material hurled by the hammers impinges squarely against these surfaces regardless of the striking point. The action in this impact zone is a succession of violent blows, first from hammer-to-material and then from material-to-breaker plate, and so on through the several stages of the involute series. As contrasted to the type previously described, most of the work in this crusher is done in the breaker-plate zone; the grates function chiefly as a scalping grizzly, and the clearance between hammers and grates is relatively large. A certain amount of impact breaking does take place between hammers and grates, but this is secondary to the work done against the involute plates. On friable material this machine will deliver a medium fine (0.25 to 3/8) product with some, or even all, of the grates removed.

The capacity of any given size and type of hammermill depends upon several factors. The character of the material influences the performance of this machine to a greater degree than it does that of any of the crushers previously discussed. It is only natural that this should be the case; all of the energy consumed in the crushing chamber is delivered by free-swinging hammers, and it is to be expected that there would be a considerable difference in the effect of these impact blows upon materials of varying physical structure. Higher speeds will of course produce better shattering effect to take care of hard rock, but there are definite limits, both from mechanical and operational standpoints, to the speed of any particular mill.

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.

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.

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 do; furthermore, the grate bars, when any are used, must be spaced closer, which means that the open area of the grate section is reduced.

When the grate bars are spaced widely, or dispensed with, and the sizing is done over a closed-circuited screen, product size has the same direct influence upon capacity because, the finer the screen openings, the more return load and, hence, the less original feed that can be handled by the mill.

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 medium-size hammermill on limestone, turning out a 10-mesh 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 size; which 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 all; in 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 body; consequently the energy absorption, and hence the shattering effect, is much greater on the 3 piece than it is on the 1/2 particle.

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 theapproximate 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.

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 gradation; high 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.

The design of the crushing chamber will also affect product gradation. In general, those machines which perform most of their work by straight impact action will turn out a more uniformly graded product than mills which depend upon interaction between hammers and grates for most of their reduction. This is only natural in view of the fact that attritional grinding is minimized in the former type of mill.

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.

The Jeffrey Swing is a relatively small Hammermill Pulverizer and is made in several types and a large number of sizes for handling large or small capacities and light, medium, or heavy work. Some of the materials being successfully reduced by this pulverizer are coal, coke, copper ore, barytes, gypsum, kaolin, magnesite, chalk, clay, cement rock, dolomite rock, phosphate rock, and limestone.

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.

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.

A metal catcher attachment is available for use on all sizes of pulverizers where tramp iron may be encountered. It may be specified when unit is ordered or obtained later and installed when need arises.Let us make recommendations for your pulverizer installation. Information required is type of material to be handled, tonnagesize of feed, and desired size of product. Belt or motor drive maybe used as required.

We use a variety of machinery combinations to liberate the gold and concentrate it for recovery. The all-inclusive Turn-Key Ore Processor will take a loader-bucket of ore and produce concentrated gold and sulfides with no hands-on activity by the operator. For a less costly production system, using hand-fed machinery, we offer a jaw crusher, hammer mill, and shaker tableeach one a stand-alone component.Or for smaller-scale sampling with industrial-grade equipment, our low-cost combination of a hammer mill with an attached sluice gives the owner the ability to test many thousands of pounds of material to get a representative bulk sampling of ore values.

The jaw crusher has been a staple of the hardrock mining industry since its invention. It is used as a primary crusher for all types of ores. The jaw typically takes the larger run of mine product and produces a sized discharge for feed to a secondary crusher such as a cone crusher, ball mill, or hammer mill. We have sold our jaw crushers to many different industries over the years, but the hard rock mining industry is still the #1 purchaser of our jaw crushers.

The hammer mill or ball mill takes the <3/4 discharge from the jaw crusher and pulverizes it to liberate the values in the ore (usually gold), and one of them is a component of our Turn-Key Ore Processor. The size of the powder from a hammer mill is controlled by the size of the openings in the screen, and the discharge is processed on the shaker table. The hammer mill will produce discharge in the 20-30 mesh size. If additional size reduction is needed, a ball mill is a conventional choice instead of the hammer mill. Take a look at the procedure to determine the liberation size for a specific ore type.

If the shaker table tailings are too coarse, they can be classified with a spiral classifier, and the over-sized discharge returned to the ball mill for additional grinding. When concentrating gold ore, our shaker table will get a high percentage of the free gold >325 mesh, even down to less than 400 mesh, equaling or out-performing any table on the market. The shaker table is a component of our Turn-Key Ore Processor and it makes quite clean cuts of <16 mesh slurry between the free gold, sulfides, and tailings. The operator can sell the free gold and send the sulfides to the refiner if they contain additional values.

The spiral classifier separates the shaker table tailings into fine and coarse fractions. The coarse material is directed back to the grinding circuit to liberate more value, and the fine materialis directed to the waste settling pond.

The spiral classifier is also useful as a simple dewatering device when water is in short supply. When the water level in the classifier pool is high, only the very finest of material is discharged from the tank, and the maximum amount of material is augered up the incline, draining the water as it climbs to the upper discharge point.

The MBMMLLC Turn-Key Ore Processor is made up of several modules and provides the operator with a reasonably priced, automated system to recover values with little operator involvement. The ore is loaded at the front end with a bucket and the gold and values-bearing sulfides are recovered off the shaker table. These are offered in 1, 2, and 4-5 ton/hr models.

For the small scale miner, these are the most cost effective, industrial grade processors available for continuous operation. The jaw crusher, hammer mill and fine gold shaker table form the heart of the processor.

chain mill

chain mill

A Chain Mill is a total amateurs tool for crushing or grinding rock. It is a set of chains attached directly at the end of a 1700+ RPM motor. The chain will beat your rock to bug-dust, pulverise it, and any gold it might contain, into a size fraction so fine you will not be about to recover it using gravity equipment. That fine gold with not pan, not gold cube or sluice out. You lost the gold because the chain mill pulverised it.

For example, look at these poor miners, having purchased $1000s of dollars in small mining equipment: drill, trommel, gold cube and a freaking chain mill. See the disappointment when the fine no gold and think the are in a low grade zone of their mine.

Using the dumb hammer that a chain mill is to crush and grind rock will likely give you a false negative. This means your find no gold when you thought there would be gold; but, you dont know for sure since the chain mill pulveriser disallowed you from recovering that gold by turning it into flour gold.

Here is an alternative to the low cost chain hammer mill. A simple and low cost small jaw crusher. As you will seein the 2 videos, rock miner Dan Hurd was able to crush gold rock practically dustless and found gold when he what not expecting to find any gold. It easily recovered flat gold flakes in his gold pan.Jaw crushing prevents pulverising of the thin or wire gold and facilitates its recovery.

gold ore processing plant manufacturer gold mining equipment

This small scale rock gold processing plant is suitable for 1-2 tph capacity.It will include a jaw crusher, a hammer mill, a ball mill and 1-2 sets of shaking tables. Except these machines, you can also add a 8-10 meters belt conveyor and make a hopper with grizzly bars. It will help you to feed the ores by the load vehicle. Contact Us to get more details of this processing plant.

1. The 1st step Crushing. The Raw rock minerals will be fed into the crushers to get the discharge size less then 25mm. Usually it will need 2 crushers, the primary crusher is for cutting down the big size of rocks, and the second crushers is for getting the size of -25mm.

2. The 2nd step Grinding. The grinding machine will be ball mill or wet pan mill. If you need to grind the minerals without waters, then you should choose ball mill. The ball mill has a grinding rotary drum, there are liners inside of the drum. Usually the liners are manganese steel liners, some times, the customers ask the liners can be corrosion resistant, so we will make ceramic liners and rubber liners. The discharge size from the ball mill will be around 200 mesh. It will make a good performance for the mineral particle separators by gravity separators or flotation machines.

3. The 3rd step Separating. The discharge from the grinding machines will be in the size of 0-2mm. Most gravity separators can do a good work for separating the concentrate from the ores. It includes the shaking tables, centrifugal concentrators, jigger machines and spiral chutes. Sometime, we do also choose the flotation machines to get the concentrate mud. It depends on the ores situations.

Due to the size,shape and specific gravity of alluvial gold, the most effecient method is using washing plant. It always includes a trommel screen, vibrating sluice boxes, a centrifugal concentrator and shaking tabls. If the alluvial gold with very sticky clay, then the trommel screen should be changed into a rotary scrubber with a trommel screen.

We have more than 25 years experience, and the machines are sold to all over the world. Our engineers can go to your local mining site for leading the processing plant installation and train your staffs.
