design for single toggle jaw crusher

Typical applications for our singletoggle jaw crushers are in mining quarrying and recycling The jaw crushers handle ores rock gravel and recycled concrete These rugged machines are manufactured with heavy duty parts for constant operation and long life

The Blake crusher was patented by Eli Whitney Blake in 1858 The Blake type jaw crusher has a fixed feed area and a variable discharge area Blake crushers are of two types single toggle and double toggle jaw crushers In the single toggle jaw crushers the swing jaw is suspended on the eccentric shaft which leads to a much more compact design

Today the most commonly used types of jaw crusher are the single toggle and the double toggle designs The original double toggle jaw crusher was designed by Eli Whitney Blake in

The Blake crushers are single or double toggle drives The function of the toggles is to move the pivoted jaw The retrieving action of the jaw from its furthest end of travel is by springs for small crushers or by a pitman for larger crushers

Designmethodologyapproach The swing jaw drive mechanism of a single toggle jaw crusher is modeled as a planar crank and rocker mechanism with the swing jaw as the coupler link Starting with the vector loop closure equation for the mechanism equations of the position

In contrast the single toggle jaw crusher has fewer shafts and bearings and only one toggle which goes from the bottom of the swinging jaw to a fixed point at the back of the jaw crusher The eccentric is located at the top of the swinging jaw and is part of the shaft

A double toggle crusher has two shafts and two toggle plates The first shaft is a pivoting shaft on the top of the crusher while the other is an eccentric shaft that drives both toggle plates The chewing movement which causes compression at both material intake and discharge gives the single toggle jaw better capacity compared to a double toggle jaw of similar size Metso’s jaw crushers are all single toggle

The single toggle crusher is designed for a high capacity throughput due to the elliptical movement of the swing jaw which also assists in the discharge of the crushed material As the single toggle crusher will achieve far higher capacities than the double toggle design they are often used as a primary crusher

Single Toggle Jaw Crusher Design The Jaw crusher is used for Primary crushers and Secondary crushers for crushing all kinds of minerals and rocks with compressive strength less than 320 mpa There are two types of Jaw crushercoarse jaw crusher and fine jaw crusher

Jaw plate kinematical analysis for single toggle jaw crusher design Abstract Jaw crusher is a kind of size reduction machine which is widely used in the mining and aggregates industry The interaction between jaw plates and material particles brings the inevitable and serious wear to the jaw plates during the jaw crusher operation which not

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 revealing ways to improve its performance

Design optimization and analysis of swing jaw plate of a single toggle jaw crusher jaw crusher is a type of size reducing machine that is widely used in areas of minerals aggregates and metallurgythe work is useful for a new prototype design of this type of machine in frame optimization and new chamber design of the jaw crusherhe

A review on the design and operations challenges of a single toggle jaw crusher is presented Strength and fracture toughness of the material to be crushed are intrinsic properties that determine the time and energy required to crush the material Economy of the crushing process is partly dependent on the angle of

Design of lighter weight jaw crusher will require a more precise accounting of the stress and deflections in the crushing plates than is available with traditional technique The design of swing jaw plate is carried out by using CAD ie jaw plate has been solid modeled by using CATIAV5R16

Four Toggle Bearing required in a jaw Crusher TOGGLE PLATES The toggle plates are fabricated from MS plates and well designed for correct jaw movement The toggle bearing serves as safeguard in case of uncrushed materials enters between the jaw plates The Toggle plates get broken saving the breakage of other parts like bearing Crank shaft etc

Technical specifications and features of our TST Jaw Crushers include Efficient crushing motion modular frame and a simple low maintenance design Single toggle jaw crusher Chamber design that enables the TST to efficiently crush hard material via a combination of

Jaw crushers are a popular alternative to primary gyratory crushers since they can process large amounts of hard material efficiently Due to their smaller physical size jaw crushers are also ideal for tight spaces such as underground mining and mobile crushing applications

Single Toggle Jaw Crusher Stone Jaw Crusher Aggregate Jaw The single toggle crusher is lighter than the double one so it is much easier in installation and in the use of the mobile device How Single Toggle Jaw Crushers Work The single toggle crusher was designed as a simpler and lighter crusher between the 1920s and 1950s

The JW Series of single toggle jaw crushers is designed with a tight crushing chamber nip angle and an aggressive crushing stroke to maximize productivity The accompanying table gives typical outputs for our range of machines based on dry free flowing material with a crushing work index of 16 and a bulk density of 100 lbscu ft 1600 kgcu m

Design Singletoggle jaw crushers are characterized by the swing jaw being suspended directly on the eccentric drive shaft and the lower part of the swing jaw being braced against the crusher frame by means of a toggle plate

ABOUT Single Toggle JAW CRUSHER Heavy duty with robust design single toggle Jaw Crusher is having Mild steel fabricated body Body is strengthened to withstand heavy load Main Eccentric shaft is running on antifriction bearings Jaw plates and chick plates are made from highly wear resistance manganese steel Oscillating Jaw is fabricated from mild steel which is fitted on main shaft
