double roll & teethed roll crusher

double roll & teethed roll crusher

Although its brief period of popularity passed some thirty-odd years since, and only a few sets were installed before interest reverted to other types, the high-speed double roll crusher developed by Thomas A. Edison shortly before the end of the last century warrants a place in any discussion-of crushing equipment. In 1960, the largest machine of this type the 6 x 7 foot giant rolls were huge crushers, judged even by present-day standards; they have an unobstructed receiving opening 7 x 7 foot and their capacity on individual skip-loads of stone is enormous, although, as will be explained, they cannot maintain this peak capacity over a period of time.

Mechanically, the teethed roll crusher is a very simple machine. The two rolls are carried in bearings, supported on two very heavy and rigid bed castings which are secured on the concrete foundation by a number of large anchor bolts. The bearings, in addition to being bolted to these bed castings, are prevented from spreading by pairs of large tie-rods which pass through them above and below the roll shafts. Unlike the smooth-face crushing rolls we have described, these tension rods are not cushioned by springs. The machine is surmounted by a heavy cast rectangular hopper, all sides of which are vertical. Each roll is independently driven by a flat-belt pulley.

The roll-centres are octagonal in cross section, each face being provided with a spline groove and a series of tapped holes for securing the chilled- iron wearing plates. These wearing plates have the sledging knobs, or teeth, cast on their outer surfaces. Thus we have a roll surface that resembles that of the one rollcrusher, except that the faces of all teeth are sloped instead of radial on the advance side. The usual practice is to fit one roll entirely with so-called regular teeth, and the other roll with six rows of regulars and two rows of higher (slugger) teeth.

The peripheral speed, or tip-velocity, of these rolls is much higher than that of any of the machines we have previously described. The range of the smooth-face rolls, for example, is from about 400 ft/min for the small 12-in. rolls, to 2000-2200 feet/minute for the heavy-duty 72 machine. The single-roll crusher has a tip speed of 400-450 ft/min while the 6- x 7-ft teethed roll crusherhas a normal, no-load, surfaces speed of just under 3500 ft/min. It can be readily appreciated that this high velocity induces an extremely violent crushing action, in conjunction with the 3- to 4-in. knobs which protrude from the roll surfaces. Impact, sledging, and pressure crushing enter into the over-all performance; but impact, in this crusher, plays a far more important role than it does in the slower speed single-roll machine; and crushing, even well down along the roll faces, is more in the nature of a sledging action than it is of pressure crushing, for this action occurs in the lower-velocity crushers.

The theoretical maximum size of cube that the knobs will grip, when the rolls are set at minimum spacing, is 24; but the rolls will reduce any stone that can be introduced into the 7-ft square hopper. Large blocks will span across the tops of the two rolls; immediately the slugger teeth on the one roll so equipped go to work on these blocks and quickly shatter them into pieces that can be gripped between the sets of regular teeth; from this point on, the action is a mixture of sledging and pressure crushing. The same selective segregations which we described in connection with the single-roll machine occur in the double-roll crusher; the smaller pieces are cleared quickly, leaving the roils free to work on the larger blocks.

The entire performance on individual skip-loads of stone takes place in a very short period of time. Ten- ton loads of mixed-size medium limestone will clear the crusher in from 10 to 15 sec.; large single blocks, weighing from 6 to 8 tons, are crushed in from 5 to 20 seconds, depending upon the toughness of the individual piece, and upon the way it happens to land in the crushing chamber. These performances were clocked on ma-chines turning out a 6 product.

The short-time transfer of energy, especially when crushing large blocks, is very high; so high in fact that it would not be economically feasible to provide sufficient motive power to deliver it. The usual practice, when these rolls are driven electrically, is to drive the slugger roll with a 250 HP motor, and the regular roll with 200HP,a total of 450 HP. As compared to this motive power, instantaneous energy delivery may run as high as 4000 HP, obviously far beyond the capacity of the motive equipment. But the rolls themselves, when running at normal no-load speed, have a stored kinetic energy of upwards of 4,000,000 ft -lb , and it is this stored energy that does much of the actual crushing, the motors serving to bring the rolls back to normal speed between crushing periods. In crushing a skip-load of stone the rolls may lose anywhere from 30 to 60 RPMin speed; this loss occurs partly through slowing down of the motive equipment, and partly through belt slippage. It requires from 5 to 10 sec. to bring the machine back to speed, during which time the power input will vary from 400 to 600 HP. The power required to run the rolls empty is something less than 100 hp. The average power consumption, when crushing from 3000 to 4000 tons per 10 hour day will run in the neighbourhood of 150 HP on medium limestone.

While the average power consumption of this machine compares favorably with that of other types, the rather violent fluctuation outlined and the relatively high connected horsepower are unfavourable features. It is also natural to expect that the belt slippage we have noted would constitute something of a problem over a period of time. Performance records indicate that belt trouble accounts for about 50% of the total lost time on a set of these rolls, and about 25% of the total maintenance expense.

The type of quarry equipment most commonly used in conjunction with this crusher is the three-sided steel skip, carried on a flat-top truck or flat car. These skips are provided with a shackle on the rear end, which is engaged by a hook actuated by a small hoist. This apparatus slides the skip over against the lip of the receiving hopper, and tilts it to discharge its contents. The skips discharge over a feed-roll which retards the flow of material so that the entire load does not drop into the crushing chamber at once. When the skip is empty it is pulled back on to the truck or car by a counterweight attached to the opposite end of the same cable which performs the hoisting operation.

We have mentioned the heavily ribbed hopper which surmounts the frame and extends up to the level of the feed roll. This hopper serves the double purpose of directing the material into the crushing zone, and preventing stones thrown by the slugger teeth from flying out of the crusher. It is also necessary to cover the top of the hopper with heavy netting to contain flying spalls.The straight-sided, rectangular hopper construction, and the violent agitation in the crushing chamber, tend to minimize blocking and bridging in this crusher. When bridges do occur they are difficult and dangerous to break while the rolls are running.

Practically all that we have had to say about the application of the single-roll crusher will apply as well to the Edison toothed roll crusher. It is better adapted to handling blocky stone than is the single-roll machine, because itsslugging action is much more vigorous, and it will handle any material that will not build up on the sides of the vertical hopper. It is not as simple a machine to feed as the single roll crusher, because its narrow hopper necessitates the uses of skips, or very short-bodied cars. A heavy- duty apron feeder would of course solve this problem, but so far as we know, none of these crushers were so equipped. The high peak capacity of the crusher constitutes something of a problem in plants of medium capacity. It is not economically feasible to provide elevating or conveying equipment to handle peak loads of around 4000 TPH in a plant designed to turn out that much stone in an 8 or 10 hr day; consequently means must be provided to smooth out these high surge loads. This can be taken care of by a surge bin and feeder below the crusher, or by passing the roll product direct to a secondary crusher of uniform-capacity characteristic. A feeder ahead of the rolls would smooth out peaks on mixed feed but. once a 10 or 12 ton block of stone is dropped into the crusher, that quantity comes through very quickly as crushed stone, which would render the regulating properties of the feeder of questionable value.Modified forms of this crusher were used by Edison for secondary and tertiary stages. The crushing equipment in one large plant, for example, comprised a set of 6- x 7-ft rolls (8 product), a set of 4 x 4 feet secondary rolls (3.5 product), and a set of 4 x 3 ft tertiary rolls (1.5 product), these last rolls being in closed circuit. These smaller machines were also run at high speeds, their surface velocities being slightly over 3000 ft/min.

bluetooth headset will only show as hands-free device, but not stereo. - microsoft community

Before vacation, in the sound control panel the headset would show up twice, one as stereo, and one as hands-free AG. I would have the Stereo one as my default sound device. In the Bluetooth settings it would show connected as voice and music.

I had the same problem with my Phillips Bluetooth Headphones (only hands-free audio is working). In device manager I also got reported Error Code 52. I traced the error down to a broken driver signature and therefore tried to repair system files with the DISM and sfc tools build in in Windows 10. In order to repair that behaviour you will have to:

After this process, my headphones are working as before. I think in my case the latest update of Windows/or maybe the install of the latest AMD Radeon driver somehow broke the signature of the Microsoft A2DP Driver.

Thanks greg for being condescending and completely unhelpful. Oh btw you might want to edit your canned response to include this, unless you actually still count redoing most of windows as an actual fix option. Enjoy another veto.

toothed roll crusher for coal preparation plant - ftm machinery

toothed roll crusher for coal preparation plant - ftm machinery

Toothed roll crusher is widely used in coal, metallurgy, mining, chemical industry, building materials, and other industries, and it is more suitable to crush coal in large coal preparation plant and process waste. Toothed roll crusher has a high crushing capacity. The distance between the rollers can be adjusted by hydraulic pressure. The bearing of the toothed roll crusher is centralization lubrication. Whats more, it has the advantages of optimal design, high efficiency, uniform grain, and low cost.

Protective device: The motor is connected with the retarder through hydraulic coupling to avoid dynamic overload. The sensor overload protection is very reliable. If you have mining project or chemical plant, the toothed roller crusher is prepared for you in China Fote.

The toothed roll crusher is suitable for crushing raw coal in coal mines, coal preparation plants and other industries (allowing less than 30% of coal gangue in raw coal). The crusher is also used to break other brittle materials whose hardness is similar to that of raw coal.

It has the characteristics of high efficiency, long life, full sealing, low noise, and uniform granularity. The double-toothed roll crusher is equipped with a scraper to keep the groove and working surface clean. For the toothed roll crusher, the outlet-size depends on the gap between the two rollers, the size of teeth, shape of teeth, and the number.

The double-toothed roll crusher is relatively small in volume. It consists of two tooth rolls that are mounted in parallel and rotate in opposite directions. According to the crushing capacity and the size of the discharging granularity, the two crushing rolls are uniformly filled with brushing teeth.

And the double-toothed roll crusher adopts the operation way of non-circular, non-intermesh and non-uniform, which can enhance the contact face of roller teeth, and avoid material slippage and improve crushing efficiency.

When the toothed roller rotates, the teeth on the surface of the roller can bite the materials and crush them. Each roller crusher of the crushing system is driven by a separate motor. The roller crusher is generally driven by a belt, and it constitutes the deceleration system along with the reducing mechanism.

FTM double-tooth roller crusher for sand making, limestone, rock, clay crushing has a good crushing effect on wet and sticky materials. And adherence or clogging phenomenon never occurs during the work.

The silicon-aluminum raw material is an indispensable calibration material in the dry cement production process. After the mining work, the materials need to be crushed, transported and stored. and then they are sent to the raw material mill for grinding according to an appropriate ratio.

However, the silico-alumina raw materials have strong water storage capacity and high plasticity index, especially for bauxite and marlstone with water content more than 17% and plasticity index generally above 15. Because of the viscosity of materials, it can lead to blockage and arching during the process of crushing, transportation and storage, thus affecting the normal operation of the system.

In order to solve the problem of adherence and clogging of wet-adhesive materials in the crushing stage, FTM toothed roll crusher is used to break the mixture of limestone and marl. In detail, firstly, the wet and dry materials are mixed and crushed, and secondly, the wet-adhesive materials and other limestone materials with lower moisture content are mixed into the crusher. And finally, they are crushed according to an appropriate ratio.

The toothed roller crusher machine has advantages of small volume, large crushing ratio, low noise, simple structure, convenient maintenance, high productivity, uniform particle size of crushed material, low crushing rate, convenient maintenance, sensitive overload protection, safe and reliable.

roll crusher working principle | henan deya machinery co., ltd

Roll crushers, or crushing rolls, or double roller crushers, are still used in some mills, although they have been replaced in most installations by cone crushers. They still have a useful application in handling friable, sticky, frozen, and less abrasive feeds, such as limestone, coal, chalk, gypsum, phosphate, and soft iron ores.

The mode of operation of roll crushers is extremely simple, the standard spring rolls consisting of two horizontal cylinders which revolve towards each other. The set is determined by shims which cause the spring-loaded roll to be held back from the solidly mounted roll.

Smooth-surfaced rolls are usually used for fine crushing, whereas coarse crushing is often performed in rolls having corrugated surfaces, or with stub teeth arranged to present a chequered surface pattern. Sledging or slugger rolls have a series of intermeshing teeth, or slugs, protruding from the roll surfaces. These dig into the rock so that the action is a combination of compression and ripping, and large pieces in relation to the roll diameter can be handled. Their main application is in the coarse crushing of soft or sticky iron ores, friable limestone, coal, etc., rolls of 1 m diameter being used to crush material of top size 400 mm.

Wear on the roll surfaces is very high and they often have a manganese steel roll, which can be replaced when they are worn out. The feed must be spread uniformly over the whole width of the rolls in order to give even wear. One simple method is to use a flat feed belt of the same width as the rolls. Since there is no provision for the swelling of broken ore in the crushing chamber, roll crushers must be starvation fed if they are to be prevented from choking. Although the floating roll should only yield to an uncrushable body, choked crushing causes so much pressure that the springs are continually on the work during crushing, and some oversize escapes. Rolls should therefore be used in closed circuit with screens. Choked crushing also causes interparticle comminution, which leads to the production of material finer than the set of the crusher.

There are two types of roller crusher, smooth roller and tooth roller. Smooth roller crusher crushes materials mainly by extrusion of two rollers, meanwhile also has function of grinding, it is good for medium and fine crushing of medium hardness materials. While tooth crusher crushes material mainly by chopping, also has function of grinding, good for coarse and medium crushing of fragile and soft rocks.

Double roller crusher model is named by roller diameter and length, for example model 2PG0640, 2 means two roller, P stands for crusher, G stands for smooth roller, 06 stands for roller diameter 600mm, 40 stands for roller length 400mm. Similarly, 2PGC500x750, C stands for tooth roller.

bluetooth headphones stuttering due to last win10 update - windows 10 - groovypost forums

bluetooth headphones stuttering due to last win10 update - windows 10 - groovypost forums

Above is the current build of my OS. A few weeks ago I started having a stutter in the audio of my Skullcandy Hesh2 bluetooth headphones. These headphones have worked for years just fine until just a couple weeks ago. Since then I have been down every rabbit hole that I can find online, trying to figure out WHY my headphones now have a stutter in the audio. They sound like they are out of range even if I have my headphones six inches away from the receiver. I have disabled telephony, disabled the MIC in audio settings & I have disabled the "enhancements" in the properties of the headset in Control Panel\Hardware and Sound\Devices and Printers. I located and used Driver Talent to locate and install drivers from an online source for the BT400 and my RealTek High Definition Audio device. Well, nothing changed. So, I installed my Asus BT400 receiver into another computer and it worked just fine but, this system was a previous version of Win10 [Version 1909 (OS Build 18363.1082)]. My headphones sound fine when used by my Samsung TV, and also by my cell phone.

I spoke with my companies IT department and they thought it might be part of the recent Win10 update that rolled out a few weeks ago. However before speaking with them I had decided to solve the issue on my own by backing up my personal files onto an external drive and RELOADING Win10 from scratch. Well, that may have been a small mistake. Because now I do not have the ability, locally, to roll back my build to a previous version of Win10 Home.

When I had issues with my system, it was a problem with my Bluetooth receiver. It was external to the system (you screwed it onto plugs on the back of the motherboard). It's an antenna I guess you could say.

The problem was the same as you describe, it sounded "out of range". The fact that you moved your BT400 receive to another box and it worked just fine.... kinda kills the idea that it's the receiver. The next thing I would check is a different USB port. Perhaps there is some damage on the USB port.

skullcandy crusher review | trusted reviews

skullcandy crusher review | trusted reviews

The Skullcandy Crusher are rather unusual headphones. As well as a normal headphone driver, they use a separate subwoofer in each ear called the Sensation55, powered by an AA battery. This is designed to blast your brain with low-end power. And it sure does. However, its fundamentally a bit of a gimmick and both the sound and build quality dont really match up to the 89 asking price.

There are little silver skulls on the earcups and silver ports for the sub drivers on each side, but from a company that makes some of the gaudiest headphones on the planet, the Skullcandy Crusher headphones are pretty normal in appearance.

Build quality isnt particularly impressive, though. Theyre light (not a bad thing as such) and plasticky, and the fake leather that tops the Crusher padding is as convincing as Keanu Reevess English accent.

Still, comfort is fine. The pads are generous and reasonably soft, theres enough wiggle room in the headband to make it fit just about any head and the headband doesnt dig into your skull. They grip your head with at least a moderate force, but you can wear them for an hour or so happily enough.

One slightly oddity is that tapping the side of the earcups produces a weird vibrating effect like tapping a tuning fork because of the way the subwoofer driver works. However, it isnt caused by just walking around with them on so its not a major issue. The Skullcandy Crusher have a removable 3.5mm jack cable that features a universal remote with a single button (remotes like this are much easier to make compatible with Androids, Windows phones and iPhones alike). Like the rest of the headphone hardware, the remote feels a bit cheap.

The way you turn the extra bass function off is pretty rudimentary too. Theres a plastic slider on the left earcup that alters the level, and turns it off completely if not required. The implementation of the battery is fairly good, though. The AA battery needed to power the Skullcandy Crusher headphones lives under the right ear pad, which is kept in place with a clip. Switching batteries reveals once more that these headphones are a bit flimsy, but its a subtle way to hide an AA. And is much better than trying to fit a battery box along the headphones cable.

With the extra bass feature set to off, sound is fairly good. Treble is slightly coarse, but sound balance is good, and bass response is generous without being wildly over the top. Theyre bass heavy without being offensively so. There is significant treble roll off, though, and dynamics are not as good as some other normal headphones at the price. They sound slightly flat.

The Skullcandy Crusher cans sound like a decent 40-odd pair of headphones, showing that you do of course pay for their defining feature, the bass engine. Its not a normal headphone driver by any stretch of the imagination. It vibrates a lot more than a standard headphone speaker, which is how its able to create quite as much air movement as it does. If youre looking for club-style thumping bass, the Crusher headphones do provide it and when maxed out they pump out a serious amount of the stuff. They do so with a force that you simply cannot replicate with a standard headphone driver.

Its pretty effective if youre looking to give explosions in films or games more of a thrilling impact, but approached from a pure sound quality perspective, its much less of a success. The bass is powerful, and as it is effectively completely abstracted from the rest of the sound, its marginally less muddying than it would be in an (e)xtreme bass pair of normal headphones. However, its not fast or taut. Good bass is gone as soon as it appears it makes a clean exit. The Crusher bass blooms out like Play-Doh squished through a spaghetti-maker.

Again, its a good impression of that standing outside the club experience, but anyone who thinks that is what good sound is really about has got it all wrong. But yes, it is quite fun and does add something to the experience of things other than music.

Sounding flabbier if more powerful than a good basshead set of headphones, and lacking the build quality we expect for 90, we recommend thinking twice before investing in the Crushers. However, for maximum thrills in films and games, they are still worth considering.

The Skullcandy Crusher headphones are interesting and provide the supercharged bass they promise. However, theyre a bit expensive given their sound quality and build quality isnt great either.Next, read our round-up of the best headphones
