A crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust.. Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiated.
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 ultimate primary crusher The C Series jaw crushers are overhead eccentric single toggle jaw crushers. The feed material is crushed between fixed and movable jaw dies. Movable jaw die is mounted to the pitman. Pitman motion (=kinematics) is defined by the eccentricity of the eccentric shaft and by the angle of the toggle plate.
consideration, the blindness brought by the traditional empirical designing can be greatly decreased. It is helpful to design the crusher for improved performance. Jaw crusher structure diagram shown in figure Figure.8: Single toggle jaw crusher & jaw crusher structure
• Electronic control of crusher discharge opening and feed rate. With adjustment of a crusher's discharge opening, as the production continues through an on-line coarse size analysis of the crushed product (digital image analyses). Dance, A. 2001) • More attention is being paid to the impact on crushing circuit design caused by variations
Typical commonly used crushers: · Jaw Crusher. Jaw Crusher can be used in mining, metallurgical industry, construction, road and railway building, chemistry, etc. 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 pitman is the main moving part in a jaw crusher. It forms the moving side of the jaw, while the stationary or fixed jaw forms the other. It achieves its movement through the eccentric machining of the flywheel shaft. Total back and forth movement of the top of the pitman is only about 1 1/2". This gives tremendous force to each stroke.
crushers to extend plant lifetime and boost production. The modular concept makes the C Series jaw crushers easy to install. The crusher can be installed as one compact module that includes all the necessary auxiliaries around the crusher itself. The crusher can be installed within a few days, minimizing on-site engineering and fabrication.
A toggle plate and tension rods hold the pitman tight near the bottom of the moving swing jaw. The toggle plate is designed to perform like a fuse and protect the crusher in the event that an uncrushable material enters the crushing chamber. As a rule, Jaw Crushers have a …
A gyratory crusher includes a solid cone set on a revolving shaft and placed within a hollow body, which has conical or vertical sloping sides. Material is crushed when the crushing surfaces approach each other and the crushed products fall through the discharging opening. Hammer crushers are used either as a one-step primary crusher or as a secondary crusher for products from a primary crusher.
Aggressive pitman motion for highest capacity and reduction; Easy to install, operate, and maintain. ® C Series™ jaw crushers are designed modular to save time and installation costs. They can be installed within a few days, minimizing on-site engineering and fabrication.
Jaw crushers are mainly used as primary crushers to produce material that can be transported by belt conveyors to the next crushing stages. The crushing process takes place between a fixed jaw and a moving jaw. The moving jaw dies are mounted on a pitman that has a reciprocating motion. The jaw dies must be replaced regularly due to wear.
b) Secondary crusher- The crushed rocks from primary crusher are sent to secondary crusher for further size reduction. Example Cone crusher, reduction gyrat- o-ry crusher, spring rolls, disk crushers etc. c) Fine crushers- Fine crushers have relatively small openings, and are used to crush the feed material in-to more uniform and finer product.
The crusher can be installed within a few days, minimizing on-site engineering and fabrication. Ultimately, this leads to a signiﬁcant savings in time and installation costs. Wide range of options C Series jaw crushers can be customized with options for any application.

Pitman : Pitman" means "connecting rod", but in a jaw crusher it doesn't connect two things. The pitman refers to the moving jaw in a jaw crusher. It achieves the reciprocating movement through the eccentric motion of the flywheel shaft. This creates enormous force in each stroke. Jaw crusher Pitman is manufactured from high quality steel plates.
Engineering prowess: Cone crushers, vibrating screens that ...
Jul 03, 2020· The double toggle-jaw crusher's system is controlled by a pitman that moves up and down via an eccentric shaft. This results in the toggle plates to flex and stretch, which causes the swing jaw to oscillate. thyssenkrupp's engineering prowess allows the swing jaw to oscillate as the crushing chamber narrows.
furthest end of travel is by springs for small crushers or by a pitman for larger crushers. During the reciprocating action, when the swinging jaw moves away from the fixed jaw the broken rock particles slip down and are again caught at the next movement of the pitman and are crushed again to …
Jaw crushers are one of the most commonly preferred crushers due to their ability to crush all kinds of materials of any hardness, as well as their low-cost operation and easy maintenance. Spherical, self-aligning roller bearings, straight-bore pitman bearings and tapered-bore body bearings provide maximum strength to the pitman shaft and ...
