A jaw crusher is a machine that breaks down big rocks into smaller ones. It has two jaws, one fixed and the other moving, that work together to crush the material. The fixed jaw is mounted on a frame and cannot move, while the moving jaw is connected to an eccentric shaft. Jaw crushers are used extensively in the mining, quarrying, and ...

A flywheel stores the energy of the jaw crusher during the empty stroke and then releases it at the right moment in order to crush the material. This helps to create a uniform load energy so that energy is conserved. In fact, there are two flywheels on a jaw crusher, one that connects the V-belt to the eccentric shaft to transmit kinetic energy.

9.3.2.1 Jaw Crusher Operating Principle. There are two main components: a fixed and a movable jaw plate. The motor-driven eccentric shaft through suitable hardware makes the movable jaw plate travel in a regulated track and hit the materials in the crushing chamber comprised a fixed jaw plate to assert the compression force for crushing the ...

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. The crushing force is doubled compared to single toggle crushers and it can crush very hard ores. The jaw crusher is reliable and robust and ...

Introduction: Jaw crushers are powerful machines that are widely used in the mining, quarrying, and recycling industries. These machines are designed to crush large rocks and ores into smaller pieces for further processing. A jaw crusher consists of a fixed jaw and a movable jaw, with the latter being driven by an eccentric shaft that moves the …

The eccentric shaft is the main shaft of the crusher, which bears a huge bending force. It can transmit the rotational motion of the motor to the movable jaw. The eccentric shaft is made of high-carbon steel for durability and resistance to bending.

Jaw crushers can be divided into two basic types, single and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation, along with the toggle plate, causes a compressive action. A double toggle crusher has two shafts and two toggle plates. The first shaft is a pivoting shaft on the top of ...

The jaw crusher works by using a moving jaw and a fixed jaw to crush and grind the rocks. The material is fed into the jaw crusher by a vibrating feeder, and then it is crushed between the two jaws. The jaw crusher is made up of several parts, including a fixed jaw, a moving jaw, and a toggle plate. The fixed jaw is mounted to the frame of the ...

Design and Operation These crushers may be divided into two main groups (Fig. 20-21), the Blake, with a movable jaw pivoted at the top, giving greatest movement to the smallest lumps; and the overhead eccentric, which is also hinged at the top, but through an eccentric-driven shaft which imparts an elliptical motion to the jaw.

Eccentric shaft (pitman bearing): It is behind the moveable jaw plate, and together with flywheel with toggle plate to create a motion. So, the most important thing you must do is keeping a regular lubrication to eccentric shaft, or you will spend more than four hours in changing a new one when it is broken.

Jaw Crusher Flywheel. The flywheel is a large wheel that is attached to the eccentric shaft. It provides momentum to the moving jaw, which helps to reduce the amount of energy needed to crush materials. Normally, the jaw crusher flywheel is made from low alloy high-strength steel or ZG35 casting steel.

Jaw crusher can be classified by sewing jaw's mode of oscillation. It has a simple oscillation type, complicated oscillation type and integrated oscillation type. Jaw crusher's working principle is powered by electromotor. Belt pulley, triangular belt, and trough wheel drive eccentric shaft, keeping sewing jaw in fixed reciprocation.

The eccentric shaft and all jaw crushers of any style have some sort of eccentric motion. As the eccentric rotates it pushed down on the pitman which in turn flattens the angle between the two toggles since the rear toggle is pivoting against the frame, the front toggle pushes on the swing jaw closing the gap between the two jaw …

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.

The moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. Two toggle plates from either side of the pitman are respectively connected to the back of the crusher and the swing jaw.

Small Jaw Crusher Capacity Table. Forced Feed Jaw Crushers. Small (Forced Feed Type) Jaw Crusher is ideal for small properties. A high ratio of reduction is obtained by the forced feed method of operation. The pitman moves on an eccentric shaft and rotates so that the material is constantly forced downward through the opening.
