Jaw Crushers are used to reduce the size of many different types of materials in many applications. The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan’s UniversalJaw Crusher…
Get PriceA double toggle crusher has, basically,two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. The moving jaw has a pure reciprocating motion toward the fixed jaw.
In a Double Toggle Jaw Crusher the eccentric shaft is located behind the swinging jaw. This protects the eccentric shaft and bearings from the shock loading. Two toggle plates from either side of the pitman are respectively connected to the back of the crusher and the swing jaw.
JAW CRUSHER. The movingjawof the singletoggle jaw crushermoves elliptically. A pendulum motion is being carried out by thedouble toggle jaw crusher. The crushing force is produced by aneccentric shaft. Then it is transferred to the crushing zone via atoggleplate system and supported by the back wall of the housing of the machine . Get Price
Jaw Crusheris mainly used for middle crushing and fine crushing the medium hard ores and rocks in metallurgy, mining, chemical, cement, construction, refractories, ceramics and other industrial sectors.
Jaw CrusherWorking Principle The motor drives belt and belt wheel, theeccentric shaftcauses the movablejawto move down and up, forward and backward, the angle between toggle plate and movablejawbecomes bigger when the movablejawmoves up, so that the movablejawmoves toward the fixedjaw,and the materials are pressed, crushed, or cut, as a result, the aim of crushing is accomplished.
StoneJaw CrusherStructure . RockJaw CrusherWorking Principle. The electromotor drives the belt and pulley to make the movablejawmove back and forth, up and down through theeccentric shaft. The raw material is squashed or split when movablejawplate moves towards fixedjawtogether with movablejaw.
Ajawortoggle crusherconsists of a set of vertical jaws, onejawis kept stationary and is called a fixedjawwhile the otherjaw, called a swingjaw, moves back and forth relative to it, by a cam or pitman mechanism, acting like a class II lever or a nutcracker. The volume or cavity between the two jaws is called the crushing chamber.
Mar 28, 2019· In a double-toggle jaw crusher, themoving crusher jawis driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes themovingcrusher jaw to close at the downstroke and open up during the upstroke. The toggle is …
May 25, 2019· Thedouble toggle jaw crusherhas two forms of working direction: one is a swing motion toward the fixed die plate, and the other is a vertical motion because of the rotation of theeccentric shaft. Through adjusting the movable die suspension and support mode, the processing capability, power consumption, liner wear, and moving stroke can be ...
Double-toggle jaw crusher. Jaw crushers come in sizes (gape x width) ranging from 180x250 mm (medium duty) to2150x3050 mm (heavy duty). Their capacities range from 3 t/hr to nearly 3000 t/h.

In the double toggle jaw crushers, there is a pitman part that transfers the circling action of the eccentric to the toggles. Almost all parts of the jaw crusher are made from cast iron and iron steel.

SUPERIORJAW CRUSHER—double togglemachine, reinforced by thru-rods. Sizes from 36×24 to 84×60 in. TYPE “B” BLAKEJAW CRUSHER— standard, reliable,double toggle crusher. Has wide application in medium and small plants. Five sizes, from 10″ x 7″ to 30″ x 18″.
Jaw crusheris a compression style rockcrusher, useful in crushing the medium-hard to very hard material into a smaller particle size at primary crushing stage in the crushing circuit. Applications mining, quarry, construction waste recycling, aggregate making, etc. Materials Limestone, cobblestone, cobblestone, quartz, basalt, iron ore, granite, shale, sandstone, gypsum, and a variety of ores.
The automatic hydraulictogglehas greatly reduced the time it takes to change ajaw crusher’s setting. Asjawdies wear, the hydraulictogglecan be easily adjusted to maintain a constant closed side setting while in continuous operation. An added benefit of the Lippmann hydraulictogglepackage is the ability to provide tramp release once ...
The first shaft is a pivoting shaft on the top of the crusher, while the other is an eccentric shaft that drives both toggle plates. The chewing movement, which causes compression at both material intake and discharge, gives the single toggle jaw better capacity, compared to a double toggle jaw of similar size.
1.Double toggleprovides maximum leverage to long strokeeccentric. 2. Wide entry ensures easy feeding to crushing chamber. 3. Cast steel swingjawis balanced to avoid power losses through lifting on crushing stroke. 4. Strong steel machine body and other parts are made from good quality material.
Thedouble-toggle crusherhas two shafts. One is a pivotshaftfrom which the pitman hangs whist the other is aneccentric shaftwhich stimulates the twotoggleplates. The pitman is given a purely swinging motion toward the stationaryjaw. Single-toggle jaw crushershave better feed acceptance capability than the correspondingdouble-toggle...
The invention discloses ajaw crusherwithdoubleshafts anddouble crank and rocker mechanisms. Thejaw crushercomprises a rack, a fixedjawplate, a movablejawplate, a front crank and rocker mechanism, a rear crank and rocker mechanism and transmission wheels, wherein the front crank and rocker mechanism comprises a front movablejaw, a front knee plate and a fronteccentricdrivingshaft...
Ajaw crusher’s flywheel,toggleplates, pitman,eccentric shaft, and driving motor generate the crushing action and provide the energy needed to break the material. There are some different styles ofJaw Crushers, the most common being the overheadeccentric jaw(shown above) or adouble toggle jaw.
Jan 01, 2018· The swingjawis moved against the fixed jaws through knuckle action by the rising and falling of a second lever (pitman) carried byeccentric shaft. The vertical movement is then horizontally fixed to thejawbydouble toggleplates. Because thejawis pivoted at the top, the throw is greatest at the discharge, preventing chocking.
The automatic hydraulictogglehas greatly reduced the time it takes to change ajaw crusher’s setting. Asjawdies wear, the hydraulictogglecan be easily adjusted to maintain a constant closed side setting while in continuous operation. An added benefit of the Lippmann hydraulictogglepackage is the ability to provide tramp release once ...
In aDouble Toggle Jaw Crushertheeccentric shaftis located behind the swingingjaw. This protects theeccentric shaftand bearings from the shock loading. Twotoggleplates from either side of the pitman are respectively connected to the back of thecrusherand the swingjaw.
3.Jaw crusheris even final particles and high crushing ratio.Jaw CrusherWorking principle: Motor drives belt and belt pulley, makes movingjawup and down througheccentric shaft. When the movingjawis up, the angle between lining plate and movingjawbecomes large, and this will push movingjawplate close to the fixedjawplate.
