Introduction to Jaw Crusher Equipment. Jaw crushers are a type of rock crusher that uses a fixed jaw and a moving jaw to crush materials.The fixed jaw is stationary and acts as a support for the moving jaw, which pivots on an eccentric shaft. This motion causes the crushing chamber to open and close, crushing the material between the two jaws.
The jaw crusher is one of the most admired and most sought after equipment from the house of Propel Industries. For the benefit of newcomers in the industry, here is an explainer of the various components of the Jaw crusher. A jaw crusher consists of Crusher Body Pitman Jaw plate Rear end frame Eccentric shaft
On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double roll spherical roller bearings. The swing jaw undergoes two types of motion: one is a swing motion toward the opposite chamber side (called a stationary jaw die due to the action of a toggle plate), and the second is a ...
opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square. Generally primary jaw crushers have the square opening design, and secondary jaw crushers have rectangular opening design. Jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock.
tions of the eccentric shaft with a simple motion of the moving jaw. The crusher achieves the maximum capacity at the opti-mum speed of the eccentric shaft. The opti-mum speed of the eccentric shaft is the number of revolutions that ensures that the time of a half-revolution of the eccentric shaft t 2 is equal to the time t 1
Jaw Crushers consist of two jaws which compress the material they are fed with into smaller pieces. thyssenkrupp Mining Technology offers Single Toggle and Double Toggle Jaw Crushers which differ in the location of their eccentric shaft and the type of movement of the loose jaw.

In single-toggle jaw crushers, the movable jaw is supported by the bearing on an eccentric shaft driven by the pitman to which it is attached. The pitman is supported by a toggle plate at the bottom of the ...
The eccentric shaft jaw crusher selections on the site are made of sturdy materials enabling them to withstand all kinds of impacts and are considered to be high-capacitive as well as faster in performance. These eccentric shaft jaw crusher are equipped with advanced technologies for enhanced features and superior performance.
Jaw Crushers; Cone Crushers; Typically, the initial crushing stage is completed using either gyratory crushers or jaw crushers. It is often the case that there will be only one crusher installed, and this will be referred to as the primary crusher. Cone crushers are more often used for 2nd, 3rd & 4th stage crushing steps (although not always).
This combination is mainly encountered in floor models that can accommodate large sample pieces, such as the BB 300 jaw crusher. The crushing ratio of a jaw crusher results from the maximum achievable final fineness in relation to the maximum feed size. For Retsch jaw crushers, this lies between 26 and 220. A high value reflects the capacity of ...
SMAN jaw crusher . A jaw crushers is a crushing machine designed considering a primary stage crushability for materials such as rock, mineral, ROM and building rubble. jaw crushers design focuses on compression type crushing with feed of material being received from the top of the crushing chamber that consists one side fix and other movable type …
Cone crushers are usually used after primary jaw crushers in the second, third, and fourth stages of crushing. ... The eccentric shaft, powered by the crusher's motor, makes the mantle move in a circular, back-and-forth motion. ... – Don't let fine particles and gunk build up inside the crusher; keep it nice and clean instead. If too …
The oscillating member is supported on an eccentric shaft that rotates at half of the crankshaft speed in the same direction and is driven by the crankshaft. The oscillating member, eccentric shaft and crankshaft jointly impact the piston movement and give rise to a shorter intake and compression stroke than a long expansion and exhaust stroke.
The movable jaw, which is supported from the top by an eccentric shaft, is connected to the tension arm and an angled built-in support plate that absorbs the cyclic loads in the lat section. ... In eccentric jaw crushers, the jaw facilitates the downward movement of the ore, though these kinds of crushers are not recommended for crushing ores ...
I made the jaws out of 1" plate and the sides out of 1/2" it took me two days to build the adapters and cut the eccentric shaft. I don't have a 4 jaw chuck so it took some thinking to make it work in the little lathe. Should have it done before xmas. Today I hit the harbor freight sale and picked up a hammer drill so I can drill blasting holes.
Productivity of the crusher can be improved upon by increasing the eccentricity of the eccentric shaft, use of reversible jaws, bush bearing and easily adjustable toggle plate.
RockSledger jaw crushers feature massive, stress relieved, single plate walls with deep and substantial external side stiffeners and a high quality forged steel eccentric shaft. The shaft is fully machined and has a ground finish on all bearing contact surfaces to increase resistance to shock loadings resulting in longer machine life.
Eccentric Shaft. The moveable jaw is attached to the eccentric shaft and is where the energy is generated. Also called the pitman, the eccentric shaft is rotated by the flywheel that pulls the arm up and causes the toggle plates to move. This forces the swing jaw to be pushed outwards towards the stationary jaw, crushing the materials.

Wearing parts in the gyratory crusher may be either chilled cast iron or manganese steel, depending on the character of the material to be crushed and the particular class of service for which the machine is intended. Standard crushers, in the small and medium sizes, are customarily fitted with chilled-iron head and concaves for …
Attached to the swing jaw; oscillates via the eccentric shaft. Eccentric Shaft: Converts the rotation of the drive motor to the reciprocating motion of the swing jaw. Made from high-strength steel; positioned to create an angle for effective crushing action. Toggle Plate: Provides support to the bottom of the movable jaw. Acts as a safety device.
The main shaft that rotates has a large flywheel mounted on each end. Its eccentric shape initiates the movement of the moving jaw in and out. The eccentric shaft …
