Our American-made Eagle jaw crushers are designed to process abrasive hard rock, using the time-tested overhead eccentric design. We can provide increased component life, reduced down time ...

Jaw crusher is an important equipment on many mine production lines, There are 4 bearings on the eccentric shaft for jaw crushser: two on each side of the jaw frame supporting the shaft and two at each end of the pitman. ... Normally they are spherical tapered roller bearings on an overhead eccentric jaw crusher.

Jaw crusher eccentric shaft taper bearing the original short life, … Bearing parts of the assembly shown in Figure 2. Jaw crusher eccentric shaft bearing repair. MPS – Cedarapids JS Series. We have taken our jaw crushers to a new level of reliability and convenience. … • High strength eccentric shaft – Enlarged diameter with ...

In the history of crushers, both chronologically, and by virtue of its standing in the field of heavy-duty crushing, the Blake jaw crusher stands first in the list. All of the large, heavy-duty primary crushers of the jaw type are built around the Blake principle which, for simplicity and brute strength, is unsurpassed by any mechanism thus far devised for rock and ore breaking.

The eccentric shaft is a critical component of a jaw crusher, responsible for transmitting the rotational motion of the motor to the movable jaw. Its primary function is to move the movable jaw up and down, providing the …

The eccentric shaft is positioned behind the swing jaw, and the toggle plates connect the lower part of the swing jaw to the drive mechanism. As the eccentric shaft rotates, it drives the toggle plates to move, creating a powerful crushing action as the angle between the two toggles becomes more acute.

The Sample Jaw Crusher is simply a smaller scale version of the same overhead eccentric design Jaw Crusher first made popular by McLanahan's Universal line of Jaw Crushers a century ago. ... 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 ...

As a compression type crusher, jaw crusher is comprised of a V-type two casting plates; one is a fixed jaw and the other is moving jaw. +90 312 815 14 59 [email protected] Mon ... It compresses input materials between itself and fixed jaw with the help of eccentric shaft. Later, you may get the crushed material in the desired size.

Eccentric-shaft press – Definition and More from the Free … Definition of ECCENTRIC-SHAFT PRESS: a punch press in which pressure is applied to the slide by means of an eccentric shaft .

The eccentric shaft is a shaft that runs through the frame of the crusher and is connected to the movable jaw. In a jaw crusher, the eccentric shaft is a crucial component that serves as the ...

The moving jaw rotates around the eccentric axis as well as swings around the same center (Fig. 2).By removing the moving jaw suspension shaft and the front toggle plate of simple pendulum jaw crusher, and suspending the moving jaw on eccentric shaft to combine the connecting rod and the moving jaw into whole, a compound pendulum jaw crusher takes …

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.

Jaw crushers include Superior, Type "B" Blake, Fine-Reduction, and Dodge — sizes, 4 by 6 to 84 by 66 inches. A reciprocating machine, the crushes material in ... 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 ...

The moving jaw rotates around the eccentric axis as well as swings around the same center (Fig. 2).By removing the moving jaw suspension shaft and the front toggle plate of simple pendulum jaw crusher, and suspending the moving jaw on eccentric shaft to combine the connecting rod and the moving jaw into whole, a compound pendulum jaw crusher takes shape, which is …

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.

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.

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 will travel in a greater arc.
