They're also popularly known as the "Blake type" because of their similar mechanism to the original jaw crusher by Eli Whitney Blake. For a long time, this has been the standard for breaking abrasive and hard materials, having been used for over a century. This variation has a higher energy-efficiency as well as a longer useful life.
Jaw crushers are classified based on the position of the pivoting swing jaw. There are three main jaw crusher types: Blake crusher – the swing jaw is fixed at the lower position. Dodge crusher – the swing jaw is fixed at the upper …

Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first overhead eccentric jaw crushers. Since that time, this robust design has continued to be the basis of the Universal Jaw Crusher design. In addition to the standard jaw crusher design, McLanahan also produces the H-Series, which features adjust-on-the-fly capabilities.
The working principle of jaw crushers is based on the reciprocating movement of the movable jaw that compresses and crushes the rock or ore between itself and the fixed jaw, as the material enters the zone between the jaws.
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 …
Jaw Crushers. Jaw crushers consist of a rectangular frame with a fixed jaw plate and a jaw stock carrying the moving jaw. The moving jaw swings toward the fixed jaw in the forward stroke, the material is crushed, and discharge …
Double-toggle jaw crushers. In a double-toggle jaw crusher, 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. The toggle is kept in place by spring-loaded tension rod.

Use the adjustment mechanism: Most jaw crushers have a hydraulic or mechanical system for adjusting the CSS. Follow the manufacturer's instructions for using the adjustment mechanism. Typically, there will be a control panel or lever that allows you to move the jaw plates closer together or farther apart to adjust the CSS.
What is a Jaw Crusher? One of the most common types of aggregate equipment that you'll encounter is a jaw crusher, also sometimes called an impact crusher. The only difference between the two types is the types of rock they are designed to crush. Recent Equipment. Browse all equipment. 2015 L60G. 2777 hours.
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 jaw up and down.
Jaw crushers are commonly used in the aggregates industry and are designed to handle large, blocky materials. Gyratory crushers are often used in primary crushing for high-capacity crushing plants and are well-suited for use in mines and quarries. Impact crushers are ideal for producing high-quality end products and are used for crushing soft ...
product size and mechanism used. Based on the mechanism used crushers are of three types namely Cone crusher, Jaw crusher and Impact crusher. The first stage of size reduction of hard and large lumps of run-of-mine (ROM) ore is to crush and …
This paper conducts a comprehensive study on the optimization design for crushing mechanism of double toggle jaw crusher. The optimization aim is to reduce characteristic value of moving jaw plate, to raise capacity of jaw …
A jaw crusher essentially crushes large rocks to a more usable size. They're typically the first-line machinery used in the material reduction for several applications. This includes rock quarries, sand and gravel, …
A jaw crusher is an indispensable tool in the mining and construction industries, known for its power to fragment hard materials such as rock and minerals. ... Acting as a safety mechanism within the steel frame, this plate will break under excessive stress, preventing potential damage to the machine—reflecting intelligent crusher design ...
A jaw crusher operates by the movement of a movable jaw in relation to a fixed one to crush large rocks into smaller pieces. It does this by using a spinning shaft that makes the movable jaw move back and forth.
A critical point in the operation of large jaw crushers is the arrangement of the swing jaw and its supporting shaft. 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 the shaft! Another point has been lubrication.
A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming …
Unique Hydraulic Release Mechanism - . ... Aggressive crushing action already at inlet of jaw crusher and less blockage at inlet ... Videos. THE STANDARD offers mobile crushing, screening and separating equipment as well as the single crusher unit to be integrated in a stationary solution.
The purpose of this article is to obtain a comprehensive mathematical description of the kinematics of a double-toggle jaw crusher. The driving mechanism of the crusher is modeled as a planar six bar linkage. Two closed position vector loops that characterize the configuration of the mechanism are used to derive expressions for the angular ...
It will be noted that the motion is a rocking one. When the swing jaw is rising, it is opening, at the top, during the first half of the stroke, and closing during the second half, whereas the bottom of the jaw is closing during the entire up-stroke. A reversal of this motion occurs during the …
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.
