cone crusher plant design

cone crusher plant design

The trend in the design of fine crushing plants is in the direction of the horizontal arrangement with all crushers on a single floor. Conveyors from the coarse ore bin or stockpile, feed the scalping screens which are usually double decked. When the feed to the fine crushing plant contains less than 15 percent passing 19MM ( In.) and less than three percent moisture, the scalping screens ahead of the secondary crushers can be eliminated without adverse effects to the crusher.

The use of hydraulic mechanisms for monitoring and controlling fine crusher settings from a central control room gives the operator a means for maintaining overall crushing plant efficiency. All that is needed for complete automatic control is the proper coupling of the power draft and volumetric controls of one stage of crushing to the positioning mechanisms of the preceding stage to insure the best balance between successive stages of crushing.

This design is intended to operate in open circuit. With fairly constant ore characteristics and where the feed to the fine crushing plant contains less than 15 percent minus 19MM () , screening ahead of Standard can be omitted. The Standard crusher closed side setting in this case is usually between 28MM and 37MM (1-1/8 and 1) , Power requirements and maintenance are low due to the elimination of surge bins ahead of the Short Heads, closed circuiting conveyors and transfer points. The crushing plant product is controlled by the screens between the Standard and Short Head crushers and the closed side setting of the Short Head crushers. With this design it is a requirement to maintain a 6MM to 10MM ( to 3/8) setting to produce a mill feed that is nominally minus 19MM ().

The stacked arrangement is somewhat inflexible in relation to expansion, since a unit requires three crushers plus conveyor extensions. With the lack of adequate surge between the Standard and Short Heads, the degree of automation is limited; therefore, it becomes difficult to have all three crushers in the unit operating at maximum efficiency,

This design is also an open circuit arrangement with some of the same limitations described in A, With two crushers in s unit or line, the automation is improved to a degree, but the lack of surge between the crushers prevents optimization of feed rate and power draw. Finer crushing is possible with this design since the closed side getting or the coarse Short Head is held to between 12MM and 15MM ( and 5/8) in comparison to the 28MM and 37MM (1-1/8 and 1) setting on the Standard described in arrangement A.

With this type of layout the location of crushing and screening equipment is quite similar with either open or closed circuit crushing. For closed circuiting crusher feed, larger or multiple vibrating screens are required ahead of the third stage crushing unit.

This arrangement is similar to that in B except that all screening is done following the crushing stage permitting even greater feed rate and power control through automation. Flexibility in expansion, screen deck openings, and ease of maintenance are important advantages in this design.

A significant advantage to this approach to fine crushing is that the necessity of matching screening units to crushing units is eliminated. When matching screening units to crushing units, the tendency is to undersize the screening units. The separate screening location minimizes the possibility of having the screens limit the fine product capability of the crushing plant. Since screening capacity can be easily expanded, the layout shown permits closer sizing of screening units to actual capacity requirements.

This layout allows for use of a standby screen or screens so that crushing operation is not affected by screen maintenance or changing of screen cloth. With any other of the arrangements shown, the cost of standby screens would be prohibitive. Screening requirements can change seasonally with moisture or as ore characteristics change with mine advance. Here, screens can be cut in and out of the circuit as required.

The layout is simple to expand. Crushers and screens are relatively close to grade, crane accessibility to equipment is good. Screens and crushers are basically at the same elevation allowing easy operator accessibility and inspection. Close instrumented control of crusher operation is possible.

cone crusher operating variables

cone crusher operating variables

Although past investigations have been conducted to determine crushing relationships, no program which covered a broad range of crushing conditions had been conducted. The previous studies appear to concentrate on small segments of the overall picture and did not fullfill our desired information objectives. Due to the broad range of variables utilized in a production size crusher, is believed to be the most comprehensive study of its kind as of this date.

The principles developed by the Symons brothers in 1925, when they patented the cone crusher as we know it today, are still being used in the machine known as the Symons Cone Crusher. During the development of this novel crushing concept, a technique known as the fall of material (called the Bouncing Ball Theory by some) was used to determine an idea as to the proper head angle, eccentric and speed of eccentric rotation. The final variables used for the Symons Cone Crusher design were, therefore, the logical conditions to start with and use as a reference against which other variables could be compared.

Other tests, conducted in the field and at the MRTC, have confirmed that the eccentric speed should not be reduced below the speed normally used. Similar tests have indicated that the eccentric throw should not be increased significantly above that normally used. It was logical, therefore, that the speed and eccentric should be given significant increases and decreases, respectively during a testing program. The head angles selected were based upon the range of cone crusher head angles being used. It is believed that the majority of the crushing variables used by the various cone crusher manufacturers are covered by the variable ranges selected.

Five hundred tons of 3 (76.2mm) x 1 (31.7mm) limestone was purchased from a limestone quarry near Milwaukee for use as the test material. All the material was obtained on the same day from the same part of the quarry to minimize fluctuations in material characteristics during the test program. Due to the large number of tests (135), no repetitive testing was thought to be necessary.

The material was fed to the crusher at a rate which would either utilize the total horsepower available or fill the crusher cavity. Normally, the horsepower was the limiting factor with the (6.35mm) and 3/8 inch (9.53mm) settings while the cavity capacity was the limiting factor at closed side settings above the 3/8 inch (9.53mm) value.

After either of the two criteria were obtained, the crusher was run until steady operating conditions were achieved. The crushing circuit was then stopped and a belt sample taken. After being weighted, this sample was split to a size convenient for screen size analysis.

Closed side settings were determined by passing a lead slug approximately 2 inches (50.8mm) thick through, the crusher prior to starting the test. This slug was then measured and the value recorded as the crusher setting for that test.

The data from all 135 tests were simultaneously supplied to a canned statistical package known as S.P.S.S. for the equation development. The S.P.S.S. package used was supplied by the Control Data Corporation (CDC) program library. Using a stepwise regression procedure resulted in an indication of each variables importance in relation to the dependent variable, horsepower. Stepwise regression results in each independent variable being entered according to the respective contribution of each to the explained variance (the variability of the dependent variable explained by the regression line)

The R value indicates how well the regression equation fits the sample data. The R value is obtained by dividing the regression sum of squares by the value for the regression sum of squares plus the residual sum of squares. The regression sum of squares being the amount of variation in the independent variables associated with the regression on the dependent variable. The residual sum of squares is the variation of the independent variables not associated with the regression of the dependent variable. This variation is due to the variation in sample data.

C.S.S. = Closed side setting (inches) Eccentric = Eccentric throw (% of normal) Head Angle = Head Angle in degrees from horizontal Speed = Linear Speed in ft./min. of the closed side setting at outermost point of liner Horsepower = Dependent Variable being predicted

The closed side setting therefore accounts for an explained variance of 43%; the eccentric 22%; the head angle 13%; and speed 1%. The R value of .79 indicates that an unexplained variance between the equations developed and the data of 21% exists.

Each of the above were represented by an equation containing the C.S.S. for each eccentric value at the head angle selected. Tables 1-2 show the R values for capacity and horsepower. In nearly all cases the R values for each eccentric value are excellent. Obviously the change in eccentric has a large effect for each head angle as evidenced by the excellent R values developed for the individual eccentrics and the relatively poor R obtained by combining all data for each head angle and developing an equation. This relationship holds true for both the capacity and horsepower predictions.

In tables 1-2 the column labeled Correlation at the 95% confidence level indicates whether a null hypothesis (H0: the values obtained were from a population for which no correlation existed) can be rejected. If a yes is indicated, you can be 95% confident (statistically) that the information used came from a population of data for which a correlation exists. In all but one case, we were able to reject the null hypothesis. Only the correlations obtained from the equations developed using log transformations are presented as the log transformation resulted in the best R values.

Scattergrams for each head angle and eccentric were generated from the equations developed to indicate the predicted horsepower and capacity versus closed side setting. These scattergrams are presented in Figures 1 through 6. Figures 1 through 3 indicate the effect of head angle and eccentric for horsepower consumption versus closed side setting. Figures 4 through 6 show the effects of the same variables on crusher capacity.

Regardless of head angle, eccentric throw, or speed, the closed side setting had the greatest effect on capacity and horsepower. As the closed side setting decreases the capacity decreases and the horsepower increases both changing based upon separate mathematical relationships. It would be logical to assume, therefore, for any given crusher, that an increase in closed side setting will increase capacity (up to the point where the cavity will not accept additional material) and decrease horsepower. There are practical limitations however. We cannot arbitrarily increase the closed side setting (C.S.S.) if we wish to maintain a maximum product top size. At the other extreme there is a physical limitation on how small the setting can be before the mechanical integrity of the crusher in question is violated.

Obviously, we must therefore look at the next variable which contributes to the process. The eccentricity, once again regardless of head angle or speed, has a very significant impact on a crushers capacity. As the eccentricity of the movable crushing member increases, the capacity rapidly increases. (See Figures 4-6) The eccentricity also controls, for any head angle, the horsepower consumption (do not forget the influence of C.S.S.) as shown in Figures 1-3. The horsepower draw will also increase significantly as the eccentricity increases.

It is apparent at this point that for a given closed side setting and head angle that the larger eccentric throws will produce the largest capacities and horsepower consumptions. While it is valid to assume that the amount of work done is related to the horsepower consumption, this assumption is only good up to the point where the added horsepower no longer is doing useful work, but rather is being absorbed in the crushing and supporting structures. Several examples of this wasted horsepower are adjustment ring movement or as seen in a different design the head moving away from the fixed crushing member. It is important therefore, to add horsepower only as long as the work is being done on the material and up to the point where the structural integrity of the machine is not being violated.

The next variable of importance (as per the stepwise regression) is the head angle. It is apparant that as the head angle increases, for a given setting and eccentric, that capacity and horsepower also increase. It has been previously established that a large eccentric is important. A large eccentric coupled with the 60 head angle resulted in a horsepower level far above the maximum acceptable limit at the smaller C.S.S.

An inspection of Figure 3 shows the detrimental effect of the 60 head angle large eccentric on horsepower consumption. In this instance the horsepower draw was high and erratic at the smaller settings. This situation caused a reduction of feed to the cavity to bring the horsepower within acceptable limits. Obviously the head angle must be something less than 60 if we are going to be able to fully utilize the whole crushing cavity at the rated machine horsepower. At the present time there is not enough information available to select the optimum head angle. Another test program concentrating on a broader range of head angles at a large eccentric is needed.

As we have seen, speed increase has been the least contributor to the explained variance. No effect was seen in regard to horsepower consumption. There is some indication that an increase in speed will reduce the crusher capacity (regardless of eccentric or head angle).

optimizing cone crusher performance on clay - crushing, screening & conveying - metallurgist & mineral processing engineer

We have an HP300 crusher in our operations carrying out tertiary crushing duty where it reduces material of P80 - 32mm to P80 - 16mm. The ore feed is kimbelite ore which is resulting in a clayish product build up in the crusher discharged chute and crusher cavity which in the last experience resulted in materiel build in the chute blocking it out and resulted inwearing out the counter weight, the socket and the head bush of the crusher. The crusher is in a closed circuit with a wet screen but we are not adding any water into the crusher its mainly crushing material with surface moisture in the range of 8-12%. The question is there anyone out there who has had such experience with a cone crusher and before making a decision to go to the market and buy a replacement crusher, what remedial actions to optimize performance. We have currently shut of the water on the wet screen and are running the plant in dry mode but it comes with many problem of dust generation, and we go into the wet season the little rain on the ore wil resulting in the screen caking up the reason we intended to move to wet screening but now have revered back to this undesirable state despite its disadvantages.

Clay in a cone crusher - the bane of operators for generations. One option is to look at a rotary scrubber with trommel or a rotary scrubber with a separate vibrating screen, either ahead of the primary crusher, or after the primary crusher (depending on the top size of the material going to the primary crusher). Water is added to the feed end of the scrubber, and can also be added to the vibrating screen. The fines (-8 mm to -10 mm depending on your grinding circuit feed size, can then be pumped directly to the grinding circuit. While these units are not cheap, they allow you to take out all the fines and bypass the entire crushing plant, and "voila" many of your crushing problems go away. The downside is that the fines bypass any weightometers in the crushing plant so you have to estimate these tons by other means in order to complete your metallurgical accounting. If you can give us an estimated feed rate to the crushing plant we (the collective 911 Metallurgical Group) might have some additional ideas for you. Best Regards - Andrew

Hi AJNeale thanks for the feedback, just to clarify a little bit more the feed to the crusher is closed with a screen (the one in wet operation) and the feed to the crusher is between 7-11% passing the CSS of 16mm. we are currently ruuning all proces in dry mode s o that the tertairy does not cake up but once we go into the rainy season which we are in now clogging problems manifest on the screen which we were trying to avoid by wet screen. in dry mode the caking in the HP300 disappears but in the wet season that we are in now the screen cloggs then the materail is all short circuited to the crusher with fines now ( increase in percentage passing CSS of 16mm) resultantly the caking in the crusher resurfaces.

Hello Dzapasi, since the silence is killing me and likely you too, I will take a run at this. I have some experience with high moisture crushing but am nowhere near 'an expert'. This will give you some things to review/consider.

1. Sticky material in crusher feed.2. Fines in crusher feed (smaller than crusher setting) exceeding 10% of crusher capacity.3. Excessive feed moisture.4. Material cleanliness5. Feed segregation in crusher cavity.6. Insufficient scalper and closed circuit screen capacities.

You may want to review your crusher liner shape. A cone crusher concaves may be straight (smooth), modified straight, or non-choking. Curved concaves are useful in crushing rocks containing sticky, moist, or dirty material that may otherwise clog the crusher. The modified straight concaves are a compromise between the straight and the non-choking concave types. These shapes do not affect the crusher capacity very much. These liners were originally designed for high-speed gyratory crushers and may be (or not) adapted to cones?

It is lots and lots of work but you may have to demand more frequent cleanup of places where you know material will stick. Hammers, air lances, long bars or other tools. Have you tried teflon lining of some chutes or sidewalls?

Are you crushing too fast? Do you have spare capacity or wasted operating time during which you could crush slower which would allow you to handle those fines a bit better? What is your current crusher operating time? I have seen plant complaining of wet ore and cone crusher packing while they were only crushing 50% of the time ie: the cone was needlessly being over loaded. The cone was overloaded AND so was the screening deck before the crusher = bad screening = extra fines + extra wets into the cone.

Thanks David have pulled out some pointers and the points above gave me a lot of ideas especially on the screening media we currently use sq polyU panels and comparing with VR they are definety worth a try. On the utilization aspect we aim to run the crusher as much as possible as it has to generate a stockpile for down stream plants so the current problems on the tertiary crusher are resulting in the circuit producing less than downstream capacity. i will forward some photo's on the effects of the clayish material in the crusher crushing cavity and discharge. the liner change out i have forwarded to OEM to confirm if they have such liners to assist with our challenge. thanks once again.

The problem is with the inability of your screen to adequately wash the fines out of your crusher feed, likely combined with poor drainage through the deck beyond the spray zone(s). The most common cause of this that I am aware of is insufficient water application, usually a combination of inadequate volume and inefficient or incomplete spray pattern coverage. There should be several spray applications down the length of the deck starting after the first set of open panels and at least 2 additional applications (spray bars) evenly spaced to about 2/3 to 3/4 of the way down the deck (leave the last 1/4 to 1/3 of the deck for draining water) - there should be alternating spray and drain intervals down the deck to achieve the best wash for minimal water volume. Your crusher feed should contain no more than ~4-5% moisture, provided you can remove the fines that are transporting the excess. To determine the best moisture content you can expect, try wet-screening (washing) a bucket of crusher feed at 12 mm and immediately check the moisture content of the oversize.

If your deck is inclined, consider reducing the angle to slow the flow of material down the deck. Screen panels with "dams" on them as shown in the second photo in David's reply will help spread the material evenly across the deck and also slow it down to help both washing and draining.

On the underside of your mantle, you may be able to attach blades to knock buildup off of the eccentric support arms before it can contact the balance weight or get into your eccentric seal. You may also be able to find (or have cast) eccentric arm liners with steeper angle to better shed buildup. For buildup in the chutes, consider lining the areas that build up with UHMW polyethylene to better shed sticky material.

Thanks Craig the pointer to the water distribution on the screen really open up some avenues of areas we will need to optimize, the pointer to the UHMW polythene has confirmed a liner change idea we were throwing around so thanks for firming up this area.

I have seen a mini cone crusher used on Kimberlite that apparently had a high clay content.In order to avoid the packing build up of compacted fines in the crushing chamber they flushed with copious amounts of water. The water jets directed blades of high pressure water directly on to the mantle. I never saw it in action but from what I heard is worked very effectively.

Have you already considered Alderox or any other release agent applied directly to the crushing surfaces? I used it with success on a Sandvik 4800, crushing ceramic clay. It was also useful in chutes, sidewalls and feeders. One application per shift following 20 minutes of drying time did the job.

this is a first to hear of and would require a little more info. The application per shift was it only in the crusher or the chutes as well. is it like at shift start operator goes around problem areas and apply it. Is it a bulk application process or it quite manageable. when you were crushing ceramic clay what was the feed size to the crusher and its product size. Finally how big/complex is the applicator system, do we buy it from supplier or its a side package.

It could also be applied with a mopper but with lots of waste. The operator sprayed every problematic area at the beginning of the shift and left it to dry while conducting the pre-start check of the crushing plant. As you can see the application is quite simple and straightforward. I remember the country distributor for Alderox (3M at the time) sent me 1 gallon for free to conduct some tests.

The plant was locatedin a very dry region and we only use Alderox during rainy season. It didn't rain too often but as you know clay traps moisture. We didn't applied the product at the end of the shift for fear of overnight rains washing it away.

pebble crushing

pebble crushing

The Bagdad mill, built in 1977, was designed for a mill capacity of 36,300 tpd. An ABC (Autogenous Mill-Ball Mill-Crusher) grinding circuit was chosen. The original mill contained three completely independent grinding circuits, each containing one 9.75 m diameter by 3.96 m long fixed speed autogenous mill, one 4.72 m diameter by 6.71 m long ball mill and one 2.13 m diameter short-head cone crusher.

Autogenous mill screen undersize combines with ball mill discharge in the cyclone feed sump. Four of the six available 0.7 m diameter cyclones are normally operated. Cyclone feed density typically ranges between 63 and 68 percent solids. Cyclone pressure ranges between eight and ten psi.

The crusher bypass belt is used to allow circuit operation when the crusher is down for repairs. This has allowed the circuit to be studied with the crusher excluded from the grinding circuit. Due to critical size pebbles in the circuit, operation without the crusher results in severely reduced throughputs.

In June of 1991, Nordberg was asked to conduct a pilot plant to test this technology on Bagdads recycle material. The study indicated that a 1.83 m diameter unit powered with a 520 kw motor would be needed to handle either present dry crusher feed or crusher product. The pilot plant crusher product was much finer than that produced by the present crushers.

It is apparent that many options are available to modify the present grinding circuit by running the autogenous mills in open circuit and producing ball mill feed through one or more stages of crushing. Since the optimum circuit configuration is not obvious, the Cyprus Bagdad staff has chosen to install a WaterFlush crusher on one grinding circuit with the ability to operate either in single stage or in series with the existing dry short-head cone crusher.

improving liner wear profile - crushing, screening & conveying - metallurgist & mineral processing engineer

improving liner wear profile - crushing, screening & conveying - metallurgist & mineral processing engineer

The attachment (cone crusher wear profile.pdf)shows a before/after profile of wear parts from a cone crusher.The light line is the original profile.Thebold line is the worn profile. The phantom shows the worn liner profile where it would have been positioned in the crusher just prior to removal.The mantle displays a typical wear pattern that leaves a 'dish' in theparallel zone of the mantle just above the very bottom and a portion of the very bottom that does not wear as much.The resulting worn part has a bell shaped profile. I see this a lot on almost all worn mantles and consider this normal and there are no particularly bad negative side effects in most cases. But a) why does the bottom of the mantle not wear out and b) what can be done to the 'new' profile to prevent this from happening?

This profile is from a customer's machine and I can't verify that it was choke fed all the time, but I see this condition often enough that I think it occurs under a variety of operational conditions. I assume there might be something we could do profile-wise on the as-cast profile to prevent it.

Thank you for your reply. I had given up on anyone else contributing to this thread. The reason I want to prevent it is because the crusher tends to get less efficient and contributes to removal of wear liners that should (in my opinion) continue to perform. One would expect liners in a cone crusher to reliably wear out as in David's diagram posted a month ago. As you can from my original diagram, the phantom line represents the bowl liner at the end of its life. Notice that the liner extends radially a significant distance past the end of the gyrating mantle and I would expect to be wear off the lump at the bottom edge of the mantle. I have observed this for many years. Some cases are worse than others, but all mantles regardless of the application exhibit some degree of what David refers as ski jumper profile. Unfortunately David offered no suggestions of how the as-cast profile could be changed and/or operational changes that could be made to make the worn-out profile look like his diagram. His diagram is intuitively logical but I see this very seldom.

A cone crusher is one of many different types of crushers, like impact crushers, jaw crushers, and hammermills, that is used to process and reduce material like aggregates and construction and demolition waste.

The cone crusher distinguishes itself from these other crushers by how it operates in processing material. Similar to the jaw crusher, a cone crusher relies on compressive force to break apart the material flowing through it.

Characterized by its central conical crusher component known as the head, a cone crusher operates around a main shaft to which the head is attached that rotates eccentrically within its crushing chamber in order to achieve the proper compressive force required to reduce the material.

As material enters the feed opening around the conical head, it fills the space between the cone and crushing chamber. Because the cone rotates eccentrically, the material is gradually compressed against the inner walls of the chamber, eventually fracturing apart, and reducing in size.

Once the material is appropriately sized, it falls through the gap between the chamber walls and the bottom of the cone, discharging from the bottom of the crusher. The gap between the chamber walls and the bottom of the cone can often be set in order to precisely size the material being processed.

However, cone crushers are less able to handle steel contaminants and must be protected from them by use of a magnet or other sorting means before material can enter the crusher. For this reason, cone crushers are regarded as appropriate for secondary and tertiary crushing purposes. However, if steel contaminants do make it into a cone crusher, a relief system can be activated, opening up the crusher and allowing the uncrushable material to be passed through without causing damage to the crusher itself.
