jaw crusher introduction . jaw crusher, also named jaw crushing machine or jaw breaker is the worlds most ancient form of stone crusher or rock crusher. jaw crushers main part is jaw crushing chamber composed of dynamic crusher jaw and static crusher jaw crusher simulating jaw movement of animals to complete the stone material crushing operations.
jaw crushers are sized by the top opening of the crushing chamber. for example, a 32 x 54 jaw crusher measures 32 from jaw die to jaw die at the top opening or gape opening and 54 across the width of the two jaw dies. the narrower bottom opening of the crushing chamber is used to size the discharge material.
the mechanism of movement of rocks down the crusher chamber determines the capacity of jaw crushers. the movement can be visualised as a succession of wedges (jaw angles) that reduce the size of particles progressively by compression until the smaller particles pass through the crusher in a continuous procession.
the differences between jaw crusher and other secondary crusher. firstly, they differ in the working principle. for jaw crusher, the driving power of the generator leads to the movement of the swing jaw and of the eccentric shaft and then the materials are crushed. while the working principle of cone crusher is laminated crushing.
1. simple structure and convenient operation the limestone jaw crusher uses the periodic movement of two jaws to crush materials. the structure is simple, easy to operate and maintain, and it simulates the movement of the animals two jaws to complete the crushing work. the crushing ratio is large and the work is reliable. .
the movement track of each point on moving jaw is more complex in this kind of machine, so it is called a double toggle jaw crusher. compared with the single toggle jaw stone crusher, the double-toggle jaw crusher has the following advantages less weight, fewer components, more compact structure, a better filling degree in the crushing chamber
this jaw crusher uses motor as its power. through the motors wheels, the eccentric shaft is driven by the triangle belt and slot wheel to make the movable jaw plate move by a
the swing jaw of the double toggle crusher closes up by contacting the fixed jaw during the pitmans upward movement and opens up during its(the pitman)downward movement. this crusher is extensively used by miners due to its prowess to pulverize tough particles and materials like ferroalloys and glass, lime stone, granite, black rock, iron ore
a jaw crusher is reliable and needs less maintenance than other types of crushers. a jaw crusher has one fixed and one moving surface in a v-shaped configuration. the moving jaw is mounted on an eccentric shaft. the reciprocal motion of this jaw presses the material against the fixed jaw. rotational movement is achieved via a motor and a
jaw crushers. jaw crushers are used for coarse grinding brittle, medium-hard to hard materials up to a mohs hardness of approx. 8.5. here reduction ratios of up to 1100 are possible depending on the actual model concerned. the crushing jaws are executed by us in two versions in a laboratory model with integrated control system, feeding

jaw crusher movement is guided by pivoting one end of the swinging jaw. and an eccentric motion located at the opposite end. 4 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.
jaw crusher operating principle through the motors wheels, the eccentric shaft is driven by the triangle belt to make the movable jaw rotate in a regulated track. movable jaw plate periodically comes to fixed jaw plate, and away from fixed jaw plate accompany with the movement of movable jaw part.
feb 18, 2021 popular types of jaw crushers double toggle blake type or overhead pivot movement. double toggle jaw crushers are the classic style of jaw crushers. theyre also popularly known as the blake type because of their similar mechanism to the original jaw crusher by eli whitney blake.
jaw crusher tooth plate is directly used for crushing ore parts. its structure is simple, but because of frequent contact with the ore, tooth plate is the crusher wear quickly. so it is often needed to replace the parts. there are two kinds of cross-section structures shape of the tooth plate, the smooth surface and the lattice surface.
pe jaw crusher . this type of crusher has a long history and belongs to traditional crushing equipment. its motor drives the eccentric shaft to rotate via v-belt pulley and movable jaw to carry out a periodical complex pendular movement to generate crush capacity. there are two types coarse crusher and fine crusher.
aug 29, 2016 choosing the most appropriate profile for a jaw crusher is not simple. there are no rules, since each application has a number of different variables like feeding, opening, product needs and problems. mainly because of the crushing movement geometry, such as in the fixed jaw plate lower tip and the central area of the swing jaw plate, so a
mar 12, 2021 in addition, the particle shape of the material will also affect the crushing force of the jaw crusher. 4. movement of the tooth plate. when the movable tooth plate moves, the force of the tooth plate is not synchronized between the upper and lower parts, and is deviated in some sections. the crushing stroke produces crushing force, and the
dec 10, 2019 in recent years, with the rapid development of computer technology, software simulation is used to comprehensively consider various factors that cause wear, and dynamically imitate of the crushing movement of the jaw plate, so as to more comprehensively analyze the wear rules of the jaw plate and finally reduce its wear rate.
the moving jaw dies are mounted on a pitman that has a reciprocating motion. 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
