Eccentric shaft, the main drive part plays an important role in the operation process. However, during daily production process, due to the overload operation of jaw crusher, the hardness of crushed material and the quality of toggle plate is not up to the standard, the eccentric shaft of jaw crusher is easy to be broken.
Mar 11, 2021 The lubrication of the interface between the parts of the jaw crusher is very important. It can minimize the friction generated during the operation, make the whole jaw crusher run smoothly, and extend its service life. Unlike gyratory crushers, the main lubrication used in jaw crushers
- Single-toggle jaw crushers Double-toggle jaw crushers. In single-toggle jaw crushers, the movable jaw is supported by the bearing on an eccentric shaft driven by the pitman to which it is attached. The pitman is supported by a toggle plate at the bottom of the moveable jaw. Toggle plate compressed between moveable jaw and main body.
Jaw Crushers are used to reduce the size of many different types of materials in many applications. 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.
Jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end.  The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws .For instance, a 22 x 30 jaw crusher has an opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square.
Jun 01, 2019 On installation: installation of components of jaw crusher. Next, we will learn about the installation of jaw crusher from the parts of the frame, eccentric shaft and bearings, rod bolts, brackets, movable jaw plate, and dental plates. 1.The installation of the frame. The jaw crusher is installed on the concrete foundation.
Dec 10, 2019 The material is crushed between the two jaws, so the wear of the liner is the main problem of the jaw crusher. And the types of wear and tear are mainly divided into the following cases. Bruise wear. In the jaw crusher, the ore is crushed and reduced to the required particle size.
Jaw Crusher Working Principle. Jaw crusher for crushing materials work, is the material between the two pieces of jaw plate crushing. Motor drive transmission mechanism driven jaw plate hanging around the shaft relative to the fixed jaw do periodic reciprocating motion, sometimes close, sometimes leaving in the process of moving jaw plate close
Eccentric shaft rotates, connecting rod to do reciprocating movement up and down, also do reciprocating motion drives the two pieces of thrust plate, pushing around moving jaw do reciprocating motion, crushing and discharging.This crusher adopts crank connecting rod mechanism, although have very big by the moving jaw broken reaction, while the
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. A double toggle crusher has, basically, two shafts and two toggle plates.
Jaw crusher disassembly. The most frequent repair item for a jaw crusher is to replace the thrust plate. For the crusher with the connecting rod as the whole, to remove the thrust plate, firstly, the bolt of the baffle must be unscrewed, the dry oil lubricating oil pipe should be cut off, and the thrust plate should be hung on the crane lifting
When feeding the jaw crusher, the material is poured into the crushing chamber containing the jaw teeth from the top entrance, and the jaw teeth pierced the material to the chamber wall with great power and broken it into smaller stones. Support the jaw movement is an eccentric shaft, this eccentric shaft through the body frame.
The invention discloses a jaw crusher with double shafts and double crank and rocker mechanisms. The jaw crusher comprises a rack, a fixed jaw plate, a movable jaw plate, a front crank and rocker mechanism, a rear crank and rocker mechanism and transmission wheels, wherein the front crank and rocker mechanism comprises a front movable jaw, a front knee plate and a front eccentric driving
SUBSTANCE: the invention is intended for comminution of the construction and mining materials. The jaw crusher contains the body, the movable jaw with the upper shaft of its swinging, the eccentric drive of the swinging with the driving shaft and the pushing roller, the fixer-stopper of the jaw.
The ore is to be broken down in a jaw crusher to pass through a 11.5 cm screen. The undersize is scalped before feeding to the jaw crusher. Assuming the maximum feed rate is maintained at 30 t/h and the shapes of feed and product are the same and the crusher set is 10 cm, estimate the size of jaw crusher required and the production rate. Solution
The jaw crusher is widely used in mining, metallurgical industry, building material, highway, railway and chemical industry. The PE series jaw crusher is widely applied in mine, metallurgy, chemical industry, building, highway, water conservancy, and light industry to crush or break various kinds of stones with compressive strength of not more than 350Mpa.
PEW jaw crusher using the electric motor as power,through the motor pulley, a triangle belt and pulley driven eccentric shaft, the movable jaw according to a predetermined track reciprocating motion, will enter the broken by the crushing cavity fixed jaw plate, the movable jaw plate and the side plate is composed of material, and through the

Our company product of jaw crusher is the collection of domestic and foreign similar companys’success experiences,one kind of effectiveness, energy conservation detritus equipment which is concentrateing on study .One large and medium-sized E-crushing machine is my
Jaw Crusher: The crushing chamber of jaw crusher is composed of fixed jaw plate and movable jaw plate. The fixed jaw plate is fixed vertically on the fuselage body, and the movable jaw plate is in the inclined position. The movable jaw plate continuously moves to the fixed jaw plate periodically.
The basic thrust is obtained by the eccentric movement of pitman which is transferred to lever with the help of rear and front toggle plates connect the pitman with lever and toggle block. The lever consists of one jaw plate (moving) which exerts the thrust on the other jaw plate (fixed) on the body. STEEL BODY : The body of jaw crusher is
