Introduction Jaw crushers are essential machines used in the mining and aggregate industries to break down large rocks into smaller more manageable sizes The primary function of a jaw crusher is to reduce the size of the material to a specific size range commonly referred to as the reduction ratio
C Series jaw crusher basic concepts The jaw crusher is a compression type crusher Feed material is crushed between fixed and movable jaw dies Large particles are crushed in a single layer referred to as single layer crushing Smaller particles are crushed rock on rock referred to as multi layer crushing C Series jaw crusher basic
DESIGN AND OPERATIONS CHALLENGES OF A SINGLE TOGGLE JAW CRUSHER A REVIEW C Okechukwu et al Nigerian Journal of Technology Vol 36 No 3 July 2017 815 this is being done with a view to
3 A fixed jaw mounted in a V shaped alignment is the stationary breaking surface while a movable swing jaw exerts force on the feed material by pushing it against the stationary plate The space at the bottom of the V aligned jaw plates is the output gap that dictates the size of the crushed product from the jaw crusher
Nordberg® C116 jaw crusher shares many of the same features as other jaw crusher models in the Nordberg® C Series Crusher height gives a steep cavity cross section and the nip angle high up in the cavity together with an aggressive well aligned stroke at the bottom ensure high throughput capacity and reduction
NW130 portable jaw crusher plant is equipped with the Nordberg® C130 jaw crusher 160 kW/215 hp which belongs to the Nordberg® C series jaw crusher product family C Series crushers are engineered for even the toughest of materials It is suitable for crushing materials such as granite basalt limestone and recycled concrete
18 • Single Toggle Jaw Crusher • In the single toggle jaw crushers the swing jaw is suspended on the eccentric shaft which leads to a much more compact design than that of the double toggle jaw crusher • The swing jaw suspended on the eccentric undergoes two types of motion swing motion towards the fixed jaw due to the action of toggle plate and vertical

Crushers Barry A Wills James A Finch FRSC FCIM in Wills Mineral Processing Technology Eighth Edition 2016 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
The jaw crusher does not lose any of its new condition throw when the babbitt wears in the main or in the pitman bearings The jaw crusher will handle sticky or dirty feed better than the gyratory there being no diaphragm below the crushing chamber on which such material can pack Routine maintenance and repair jobs are generally
The setting of the Nordberg C Series jaw crusher can be adjusted with two wedges without shim plates The adjustment system is mechanically moved as standard and the fully automatic hydraulic option is available to make the wedge movement even faster and safer Other safety enhancing features are the lightweight yet
The reduction ratio is driven by the Crusher Close Side Setting The actual minimum safe closed side setting of a crusher will vary somewhat for any given crushing machine depending upon the character of the material the amount of fines in the feed and whether the crusher is being operated under choke feed or regulated feed conditions It is

jaw crushers since the 1920s Today the Nordberg C Series is indisputably the world s favourite jaw crusher Where cost efficient primary reduction of hard abrasive materials is concerned C Series crushers represent the highest technical and manufacturing knowl edge All C Series jaw crushers are based on a revolutionary modular non welded
A sectional view of a jaw crusher which incorporates the Blake double toggle mechanism is shown below The Blake crusher in common with all machines of the jaw family is built into a rectangular frame at one end of which is located the crushing chamber; in fact the end of the box frame constitutes the stationary jaw The movable or swing jaw
A dynamic model of the working mechanism of a compound pendulum jaw crusher with clearance is established by the Lagrange multiplier method LMD based on the L N contact force model and modified Coulomb friction force model The correctness of the dynamic model is verified by MATLAB and Adams comparison simulation and the best selection range
The C120 can excel in mobile or portable plants where small to moderate capacity is needed Overall the C120 is an affordable jaw solution with lower operational costs C160 Jaw Crusher The C160 is Metso s second to largest jaw crusher superseded only by the C200 and has been designed for some of the hardest primary crushing applications
Nordberg® C Series™ jaw crushers are engineered for the toughest feed materials They are proven to be reliable and productive in thousands of real mining quarrying recycling and industrial applications You can rely on the Nordberg C Series as the primary crusher of
This is because the Blake Jaw Crusher integrated a key mechanical principle the toggle linkage a concept students of mechanics are familiar with In 1881 Philetus W Gates received a patent for his device featuring the basic ideas of today s gyratory crushers In 1883 Mr Blake challenged Mr Gates to crush 9 cubic yards of
The plate dimensions of the un optimised jaw crusher were modelled using ANSYS Design Modeller 2021 as shown in Fig load and boundary conditions for the static structural analysis were as shown in Fig of Experiments DoE was then conducted where the minimum and maximum values of the target parameters were matched in possible
