Jaw Crushers – Double Toggle Operation Many types of crushers use rotating hammers and other crushing elements to reduce materials by impact, shear or attrition. Jaw crushers, however, crush by compression of the material between two opposing surfaces — the jaws. The moving jaw (swing jaw) compresses the material against the stationary jaw.
Double toggle jaw crushers are commonly used in mines due to their ability to crush tough and abrasive materials The oscillating motion of the swing jaw is caused by the vertical motion of the pitman. Single toggle jaw crushers are preferred for the crushing of softer particles.
Jaw crushers are used mainly in first stage, primary crushing applications and are ideal for use in quarries and recycling demolition operations. The two main types of jaw crusher produced by Parker are both single toggle designs with the upthrust toggle RockSizer / StoneSizer model and downthrust toggle RockSledger model.
Jan 09, 2015· Single Jaw Crushers. Now, single jaw crushers include one toggle, that goes from the bottom of the swinging jaw right up to a certain point behind the the jaw crusher. Compared to double toggle jaw crushers, single ones include fewer shafts and bearings. The eccentric of a single jaw crusher is located at the top of the swinging jaw.
A critical point in the operation of large jaw crushers is the arrangement of swing jaw and its supporting shaft. While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is used—shaft is clamped in frame and jaw swings on shaft! Another point has been lubrication.
SUBSTANCE: the invention is intended for comminution of the construction and mining materials. The jaw crusher contains the body, the movable jaw with the upper shaft of its swinging, the eccentric drive of the swinging with the driving shaft and the pushing roller, the fixerstopper of the jaw.
Jan 23, 2017· A universal crusher is a hybrid of the two jaw crushers above. The swing jaw is fixed at the middle. 2. Gyratory crusher . The gyratory crusher works on the same principle as the jaw crusher but has a conical head and a concave surface. The crushing chamber is lined with a hardened manganese steel material.

Aggressive crushing action with high swing jaw encouraging material entry into crushing chamber; Fully hydraulic crusher setting adjustment; Improved manganese liner retention, protects jaw supports on both swing fixed jaws; Excellent under crusher access for removal of wire with hydraulic raise/lower product conveyor (Optional)
A jaw or toggle crusher consists of a set of vertical jaws, one jaw is kept stationary and is called a fixed jaw while the other jaw called a swing jaw, 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.
Jaw crusher complex swing includes a frame 1 with the crushing chamber 2 formed by the walls of the base 1 and the movable Kobasa cheek 3, mounted in bearings 4 on the eccentric part 5 of the drive shaft 6, mounted in the bearings 7 of the bed. Mobile shatter …
Jaw crushers are a popular alternative to primary gyratory crushers, since they can process large amounts of hard material efficiently. Due to their smaller physical size, jaw crushers are also ideal for tight spaces, such as underground mining and mobile crushing applications.
Stone Crusher JXSC company stone rock crushers include cone crusher, jaw crusher, impact crusher, mobile crusher, sand making machine, mobile crushing plant hammer crushing which can crush with more than 200 kinds of industrial as pebble, granite, basalt, iron ore, limestone, quartz, diabase, iron ore, gold, copper, etc. Primary and fine crushers are the type of crushing ...
Efficient crushing motion The frame and swing jaw crushers feature doubleroll spherical roller bearings to allow for any misalignment that may occur. Builtin protection against uncrushable material When uncrushable material is encountered, builtin safety features ensure that the equipment is protected, for reduced wear fewer maintenance ...
The swing jaws of double toggle jaw crushers have an oscillating motion caused by the vertical motion of the pitman. When the pitman moves up, the swing jaw closes, and when the pitman moves down, the swing jaw opens. Double toggle jaw crushers are commonly used in mines due to their ability to crush tough and abrasive materials.
and support bars to fix the jaw plates to the crusher. • Designed with sacial parts to protect the main compo nents of the crusher such as frame, swing jaw and bearings. This reduces total lifecycle costs and increases uptime, as it is less expensive to change the sacial parts than the main components.
transmit the crushing force, the swing jaw of a single toggle crusher oscillates and translates at the same time during operation. Deepak  and Jinxi et al.  analyzed the kinematics of the swing jaw of the single toggle jaw crusher by considering the mechanism of the swing jaw as a fourbar link mechanism, as shown in Figure 8.
The Blake type jaw crusher has a fixed feed area and a variable discharge area. Blake crushers are of two types single toggle and double toggle jaw crushers. In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher.
Introduced in 1906, McLanahan’s Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavyduty double roll spherical roller bearings.
Jaw Crushers Premiertrak 400X R400X Postscreen Premiertrak 400X Postscreen The Powerscreen® Premiertrak 400X Postscreen, is a tracked jaw crusher which excels in quarrying, demolition, recycling and mining applications.
Dec 09, 2014· • Single Toggle Jaw Crusher • In the single toggle jaw crushers, the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher. • The swing jaw, suspended on the eccentric, undergoes two types of motion swing motion towards the fixed jaw due to the action of toggle ...
All LippmannMilwaukee heavyduty jaw crushers feature an oversized, heat treated shaft forged of special alloy to provide an exceptionally large eccentric throw. These heavyduty shafts are paired with two dynamically balanced flywheels, effectively reducing vibration on both portable and stationary crushers.
carried out by researchers on analysis of swing jaw plate Kinematic dynamic analysis of the jaw crusher. Due to which the design quality of jaw crusher are improved, though there were so many researcher work done on analysis, but still there is so many area of scope to develop the analysis of swing jaw plate.
Optimum design and analysis of (the) swinging jaw plate of a single toggle jaw crusher Thesis (PDF Available) · April 2010 with 4,260 Reads How we measure 'reads'
The impact crusher adopts rotary swing while Jaw crusher has two ways for swing, one is simple pendulum and the other is a complex pendulum. In short, the former adopts a rotational swing to finish crushing work, whose trajectory is circular while the latter utilizes reciprocating swing, whose extrusion motion is a straight line.
The gyratory crusher can, just like a jaw crusher, accept boulder sizes close to m (for the largest equipment). – This crusher can handle products with a Mohs hardness that is not necessarily less than 5. – As is the case for jaw crushers, there is not any mutual sliding on grinding surfaces, but simply rolling of the nut on concaves.
A jaw crusher breaks minerals, ores of high strength. The stiffness of swing jaw plate has not been varied with changes in rock strength. Thus stiffness of swing plate is enough to crush taconite with an unconfined compressive strength (Q U ) of up to 308 MPa, may be over signed for softer fragmental. Hence the weight of the swing plate is necessary to reduced.
