The optimization design of the double toggle jaw crusher offers numerous benefits to users. One notable advantage is its improved efficiency and productivity. By incorporating innovative features, such as a larger feed opening and a deeper crushing chamber, the proposed design allows for greater throughput of materials.

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 efficiency.

For example, a 32 x 54 sized jaw crusher will measure 32 inches from the movable to stationary jaw (when measured at the top i.e. the opening), and each jaw will have a 54-inch width. If a jaw crusher is rated by jaw plate size, a suitable rating maybe 600 x 400, which indicates a 600 mm by 400 mm jaw plate dimension.

In discussing linkages, Martin [] featured the double toggle jaw crusher mechanism as an example of a machine that uses the toggle e ect to obtain a large output force that

This paper conducts a comprehensive study on the optimization design for crushing mechanism of double toggle jaw crusher. The optimization aim is to reduce characteristic value of moving jaw plate, to raise capacity of jaw crusher, and to ensure entrance and outlet dimensions of jaw crusher. Firstly, formulae are derived for displacement of the …

operation. Jaw crushers can be separated into two categories based on the movement mechanism of the moving jaw: single toggle jaw crushers and double toggle jaw crushers. In the aggregate sector, single toggle jaw crushers (Figure 2) are often preferred. Within the scope of the study, an innovation on the single toggle jaw crusher …
