There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, 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 ...
For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.

Jaw Crushers consists of main components named as stationary jaw, moving jaw, toggle plate and eccentric drive shaft. They run with four bar mechanism principle as it shown …
A hydraulic jaw crusher is a type of jaw crusher that uses hydraulic pressure to crush materials. It has a movable jaw that is operated by an eccentric shaft, as well as a fixed jaw that is positioned opposite the movable jaw. The hydraulic system allows the jaw to open and close, providing a wider range of crushing settings.
The basic design of a jaw crusher consists of a frame, an eccentric shaft, a movable jaw, and a stationary jaw. The frame is the main body of the machine and is usually made from cast iron or steel. …
The moving jaw is mounted on an eccentric shaft, which allows it to move up and down in a circular motion. As the moving jaw moves down, it crushes the material against the fixed jaw. ... Overhead eccentric jaw crushers are less common, but they are designed with an eccentric shaft that causes the moving jaw to move in a more circular …
The foundation of a jaw crusher is the frame, which provides structural support and houses the eccentric shaft, which is a critical component for generating crushing motion. Connected to the frame ...
group, has installed over 10 000 jaw crushers since the 1920s. Today the C Series is indisputably the world's favourite jaw crusher. Where cost-efficient primary reduc-tion of hard, abrasive materials is concerned, C Series crushers represent the highest tech-nical and manufacturing knowledge. All C Series jaw crushers are based on a
The pitman is journalled at the upper end to accept the eccentric shaft. The structure houses eccentric lobe and supports the movable jaw. The lower end of the pit man is guided by the toggle ...
The productivity calculation method for eccentric roll crusher has been developed based on the motion patterns of the roll, dynamic analysis of materials, flow model, and crushing model. And preliminarily demonstrated the proof of productivity concept. 2. The similarity between the theoretical particle distribution.
Design Of Eccentric Shaft For Jaw Crusher. Eccentric shaft used in jaw crusher design of impact crusher with part crusher a crusher is a machine designed to reduce large rocks into smaller rocks, gravel, or rock dust throughout most of industrial history, the greater part of crushing and mining part of the process occurred under on the eccentric …
L represents the axial length of the roller, and n represents the rotational speed of the eccentric shaft. The productivity of the crusher is given by Eq. (36). (36) Q = Q return, d o w n - Q stroke, u p + Q stroke, d o w n. Graphical representations of the data are shown in the Fig. 15, Fig. 16 and Fig. 17.
The crusher model ERC 25-25 selected for this purpose has a crushing roll measuring 2,500mm in diameter and width. The feed opening to the crushing chamber is 2,500mm wide and 1,230mm high (see table 1). Both the coarse and fine run-of-mine feed were processed, together with selected lumps of up to 5 tonnes. The equipment …
The movable jaw is the part of the crusher that moves back and forth to crush the material against the fixed jaw. The eccentric shaft is responsible for the rotary motion of the movable jaw ...
The two flywheels are respectively at the two ends of the eccentric shaft. One of the flywheels is used to connect the V-belts and the eccentric shaft to transmit the kinetic energy. The other is the flywheel that is useless in many people's eyes. In fact, this flywheel plays in the operation of the jaw crusher. Crucial role.
