As to eccentric roll crusher compared with three types of crushers above, the most distinctive feature is the liner installed outside the crushing roller rotates counterclockwise around the eccentric shaft under the influence of the reactive force of the crushed materials.
The countershaft has a bevel pinion pressed and keyed to it and drives the gear on the eccentric assembly. The eccentric assembly has a tapered, offset bore and provides the means whereby the head and main shaft follow an eccentric path during each cycle of rotation. Cone crushers are used for intermediate and fine crushing after primary crushing.
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.
With its new eccentric roll crusher (ERC ®) thyssenkrupp Industrial Solutions has developed a groundbreaking solution for the primary crushing of hard rock and ore.
ture shaft rotation must be equal to the free fall of the jaw crushers is its capacity. The capacity depends on the number of revolu-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-
The main shaft of the crusher is journaled in the spider bearing and in the eccentric bearing assembly. The spider bearing fixes the position of the upper end of the main shaft. Eccentric bearing assembly with inner bushing can be replaced, or in some models turned, to adjust the stroke.
An overhead eccentric jaw crusher has an eccentric shaft located above the jaw plates. This design provides a more even wear distribution on the jaw plates, which results in longer jaw plate life. Additionally, an overhead eccentric jaw crusher has fewer moving parts than a double toggle jaw crusher, which means it requires less maintenance.
That is where the energy comes from, the crushing action itself is generated by the eccentric shaft, and this shaft is called the pitman. This is simply a shaft with a portion of its length offset from the rest of the shaft. As the shaft is revolved that portion …
The part where this failure occurred is the eccentric bushing. As the mantle shaft comes into direct contact with the eccentric bushing, a large ring of deposited layer can be observed in the middle-upper part of the lower shaft, as shown in Fig. 2 (a). This phenomenon indicates that strong oxidation has occurred at that location.
The Ultimate Guide to Jaw Crushers: Types, Principles, Maintenance, and Selection Tips ... toggle jaw crusher is a type of jaw crusher where the movable jaw is hinged at the top and swings up and down when the eccentric shaft rotates. The single toggle jaw crusher is known for its simplicity and low cost, making it a popular choice for …
Let's delve into the jaw crusher diagram—a revealing illustration showcasing the trajectory of the movable jaw plate. In action, this plate swings on the eccentric shaft, applying a forceful compression to …

In contrast, the single toggle jaw crusher has fewer shafts and bearings and only one toggle which goes from the bottom of the swinging jaw to a fixed point at the back of the jaw crusher. The …
5. Eccentric Shaft. The pitman is put in motion by the oscillation of an eccentricity on a shaft that goes through the pitman's entire length. This force is also put on the shaft itself so they are constructed with large dimensions and with hardened steel. The main shaft that rotates has a large flywheel mounted on each end.
For decades, gyratory and jaw crushers have proved their worth in crushing hard rock. However, their application is limited by their high headroom, requiring capital-intensive construction of large-scale, costly caverns when used in underground operations. ... The eccentric shaft is driven by a V-belt drive, with the inertia of two flywheels ...
Motor power is applied to the crusher drive shaft, which in turn transfers rotation to the eccentric shaft. Rotation of the shaft causes two types of motion in the moving jaw. The first is a cyclic, pivoting open-and-close motion caused by the top of the moving jaw leveraging against a toggle plate at the bottom of the moving jaw.
Principle of Operation of our Small Jaw Crushers. Both types of Small Jaw Crushers are of the forced feed type. The main shaft is eccentric and on this eccentric shaft is mounted the movable jaw, imparting a rotary movement to the jaw. This rotary movement followed by the movable jaw actually pushes the feed down into the crusher, …
The main shaft rests in the eccentric bushing at the base of the crusher. As the eccentric rotates, the base of the main shaft moves in a circular path around the crusher centerline. Viewed from the side, you can see the motion of main shaft is like that of a pendulum as the gap closes the ore is nipped and broken.
The jaw crusher is widely used in many fields where the breaking strength is less than 320 MPa like mining, smelting, building material production, highway, railway, water …
The eccentric throw is the extent to which the mantle veers from its axis, so it defines the rate at which the material falls through the chamber. ... CH cone crushers help you find the balance between tonnage and exactness, by allowing you to change the eccentric throw quickly and easily. They are constructed with an adjustable ...
The pitman (eccentric) shaft is heat-treated, forged steel construction—of ample diameter so that stress, even under the shock of suddenly clogged jaws, is low. The shaft is carried in removable, water-cooled, babbitted bearings designed to permit quick removal or replacement without having to strip the crusher. ... While in most crushers …
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.
cone crushers is the ability to easily change the stroke length by rotating the eccentric bushing inside the crusher (see image on the right). Stroke is the distance which mainshaft and mantle moves during one eccentric rotation. It's defined by the combined eccentricity of the shaft and bushing (see image below). Thickest point of eccentric ...
Vertical shaft impact crushers – Generally recognised as a tertiary crusher, vertical shaft impact crushers (VSIs) have material fed into the centre of the crusher through a feed tube and onto the centre of a rotating table or rotor. The material is then accelerated to high velocity and is thrown into the anvil ring or outer shell.
