There have been reported cases of the crusher jaw failure due to the high level of impact, tear and shear stresses experienced by the crusher jaw during service. The purpose of this paper is to select a suitable candidate material for the design of crusher jaw that can sustain fracture by any of the three modes of failure – tear, shear and impact at low cost using CES EduPack.

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 underground for installation. Modern jaw crushers may have a main frame of welded mild steel plate.

Enterprises produce jaw crushers in various sizes: [3,4]. Classification of jaw crushers is carried out on character of movement of the moving jaw which is the basic working body of a crusher. This determines the most important technical and operational parameters of the crushers. A distinction is made between crushers with simple and complex

The steam shovel began to change the entire picture of open-pit working.With the steam shovel came the really ‘‘huge” No. 8 crusher, with its 18″ receiving opening. Up to this time the jaw crusher had kept pace with the gyratory, both from the standpoint of receiving opening and capacity, but now the gyratory stepped into the leading position, which it held for some 15 years.
Jaw crusher is one of the main types of primary crushers in a mine or ore processing plant. The size of a jaw crusher is designated by the rectangular or square opening at the top of the jaws (feed opening). Primary jaw crushers are typically of the square opening design, and secondary jaw crushers
This paper presents the effects of single-stage (jaw crusher alone) and two-stage crushing (jaw crusher followed by an impact crusher) mechanism on the mechanical properties of aggregates. A two-phase study was designed to investigate the effectiveness of two-stage crushing mechanism in improving the properties of aggregate and performance of

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.

Nonuniform settlements of a primary-crushing mill, which resulted from the operation of three heavy-duty jaw crushers housed in the mill, are described. Test results are cited for foundations with
EvoQuip, A Terex brand in Dungannon, Ireland, has launched its Bison 280 jaw crusher.The crusher can be used in construction and demolition, asphalt recycling, quarrying or contract crushing applications. The Bison 280 has been working in a granite site at Peter O’Donnell & Sons Quarry in Ireland. “The productivity and performance of the EvoQuip Bison 280 really has surpassed our

Currently, the dimensions of the largest Blake-type jaw crusher in use are 1600 mm × 2514 mm with motor ratings of 250–300 kW. Crushers of this size are manufactured by Locomo, Nordberg (Metso) and others. The Metso crusher is the C 200 series having dimensions 1600 mm × 2000 mm driven by 400 kW motors. Table 4.1.
Replicate analyses of multiple jaw-crusher splits returned highly variable Pt and Au assays but much smaller relative errors in the other PGEs. The poor Pt and Au reproducibilities are attributed to nugget effects, explicable by much of the Pt and Au in the samples being present in sparse Pt- and Au-rich grains.

Purpose – This paper aims to obtain equations that can be used to describe the motion of any given point in the swing jaw of a single toggle jaw crusher. Design/methodology/approach – The swing jaw drive mechanism of a single toggle jaw crusher is modelled as a planar crank and rocker mechanism with the swing jaw as the coupler link.
