Jaw crushers, occasionally referred to as "toggle crushers," are the most common type of crusher. Material is compressed between a moving piece of steel and a stationary piece. Cone crushers are compression crushers that use a rotating piece of steel against a stationary piece of steel to reduce material.

The jaw dies must be replaced regularly due to wear. Figure 8.1 shows two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is installed on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action of the moving jaw.

Flywheel hubs of our jaw crushers are equipped with special locking assembly which connects flywheels to the eccentric shaft. This system ensures that the flywheel is held safely and tightly on the shaft. This feature is important as the crusher has to be brought into operation under load, resulting from unforeseen stoppages.
Comprising type of jaw crusher—the robust Single-toggle and the efficient Double-toggle—these hefty machines operate on the principle of compressing materials between a stationary "fixed jaw" and a moving "swing jaw," attached to an eccentric shaft. This powerful action makes the jaw crusher the go-to equipment, laying down the ...

The Jaw Crusher was first introduced by Eli Whitney Blake in 1858 as a double-toggle Jaw Crusher. Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first modern era overhead eccentric Jaw Crushers. On the overhead eccentric style Jaw Crusher, the moving swing jaw is suspended on the eccentric shaft with heavy-duty double ...
Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaw; one is fixed while the other makes an eccentric movement. ... Large diameter forged alloy steel eccentric shaft, polished to a fine finish and with no screw threads or sharp radii that can cause stress concentrations
The overarching principle guiding jaw crushers is a compression action. A V-shaped alignment houses the fixed jaw, serving as the immovable surface that facilitates the initial breakage. Simultaneously, the movable jaw, in a swinging motion, exerts force on the incoming material, compelling it against the unyielding surface of the fixed jaw.

Jaw-crusher Construction. Jaw crushers are heavy-duty machines and hence must be robustly constructed. The main frame is often made from cast iron or steel, connected with tie-bolts. It is commonly made in sections so that it can be transported underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.
Jaw crushers reduce large rocks or ore by means of compression. Mechanical pressure is applied using the crusher's two jaw; one is fixed while the other makes an eccentric movement. ... Large diameter forged …
Structural and Design Variations. The structural and design differences between single and double toggle jaw crushers are noticeable. A single toggle crusher has a simpler, more compact design with fewer mechanical parts, whereas a double toggle crusher has a more complex structure with two toggle plates, a pitman, and two swinging jaws.
Jaw rock crusher VS gyratory crusher Different crushing principles Jaw crusher is a compression type of crushing machine. The flywheel works together with eccentric shaft and toggle plate provides a motion which pushing moveable jaw plate towards stationary jaw dies, and during the process, a compressive force squeezes raw …

Blake type crushers come in various sizes and are commonly used for primary and secondary crushing roles. How Jaw Crushers Are Sized. Jaw crushers are sized based upon the dimensions of the top feed inlet (gape) or the dimensions of the jaws. For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to …
To understand jaw crushers, it's good to know how they work. As materials, typically rock, enter the machine, the motor turns the shaft, making the swinging jaw move. This back …
While in most crushers the jaw is pressed on the shaft and the latter swings in frame, in the jaw crusher the opposite principle is used—shaft is clamped in frame and jaw swings on shaft! Another point has been lubrication. In operation, the actual movement of the swing jaw is relatively small. Result is difficulty in proper lubrication of ...

Jaw Crushers for primary reduction (from boulders up to 4-6 feet to 6-8 inches), Cone Crushers or Horizontal Shaft Impactors for secondary crushing (further reducing material to 0.5-3 inches), Vertical Shaft Impactors for tertiary crushing (creating sand-sized particles of 1/4 to 3/8 inch).
Jaw Crusher Parts. Although the jaws do the work, the real heart of the jaw crusher and its components are the toggle plates, the …
In forced-feed jaw crushers the feed material passes through the no-rebound hopper and enters the crushing chamber. Size reduction takes place in the wedgeshaped area between the fixed crushing arm and one moved by an eccentric drive shaft. The elliptical motion crushes the sample which then falls under gravity.
