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.Commonly used jaw crushers have two types: double toggle plate and single toggle plate. The former only makes a simple arc swing during work, so it is also called a simple swing jaw crusher; It Double toggle jaw crusher working principle

A double-toggle jaw crusher outweighs the single-toggle by a factor of 2X and well as cost more in capital for the same duty. To perform its trade-off evaluation, the engineering and design firmsingle toggle jaw crusher is its kinematic design. FLSmidth’s chamber design enables the TST to efficiently crush hard material via a combination of shaft eccentricity, toggle angle and chamber layout. The steep nip angle enables the units to easily crush the hardest rock at high production rates, while maintaining the necessary Crushing Systems FLSmidth

Double-toggle jaw crushers. In a double-toggle jaw crusher, the moving crusher jaw is driven by the eccentric shaft that moves the front and rear toggles up and down. Each shaft revolution causes the moving crusher jaw to close at the downstroke and open up during the upstroke. The toggle is kept in place by spring-loaded tension rod.Double Toggle Blake Type or Overhead Pivot Movement. Double toggle movement jaw crushers like the Blake style (named for the inventor of the first successful mechanical jaw crusher, Eli Whitney Blake), have long been the standard used for crushing hard and abrasive rocks, as well as sticky feeds. These jaw crushers have high energy How Does a Jaw Crusher Work Jaw Crusher Kemper Equipment

The purpose of the primary crusher is to reduce the ROM ore to a size amenable for feeding the secondary crusher or the SAG mill grinding circuit. The ratio of reduction through a primary crusher can be up to about 8:1. Feed: ROM up to 1.5 m. Product: -300mm (for transport) to -200mm (for SAG mill) Feed Rate:Contact Now +86-13879771862. Published time：25 May 2019. Crusher machines play an important role in the mines, metallurgy, building materials, quarrying, recycling, chemical and so on industries.

The original double toggle jaw crusher was designed by Eli Whitney Blake in the USA in 1857 . The motion of the swing jaw in a double toggle crusher is such that it applies an almost purely compressive force upon the material being crushed. A. Carter Russell, “New Jaw Crushers are Reliable, Affordable and Transportable,” Rock ProductsThe double-toggle crusher has two shafts. One is a pivot shaft from which the pitman hangs whist the other is an eccentric shaft which stimulates the two toggle plates. The rock shatters upon impact with the hammers, sprays against the back wall of the impactor, and then tumbles back into the hammer circle.

Dimensional data of a typical double-toggle jaw crusher are used in the derived mathematical expressions to demonstrate their application. Moreover, starting with the equation for the angular velocity ratio of the moveable jaw, with respect to the input crank, an expression for the ideal mechanical advantage of the crusher is derived.
