DOUBLE-TOGGLE JAW CRUSHER. The double-toggle mechanism, patented in 1858 by Mr. E. W. Blake, remains unrivalled for all units of exceptional power and size. Fig. 1 is a cross section of an early Blake crusher. The power was applied to an eccentric shaft rotated in fixed bearings situated close to the centre of a heavy cast-iron …

Introduced in 1906, McLanahan's Universal Jaw Crusher was one of the first overhead eccentric jaw crushers. Since that time, this robust design has continued to be the basis of the Universal Jaw Crusher design. In addition to the standard jaw crusher design, McLanahan also produces the H-Series, which features adjust-on-the-fly capabilities.

The Blake features a double toggle jaw crusher drive mechanism which gives relatively smaller movement at the receiving end of the chamber generating a powerful crushing action for large rock pieces. A refinement on the crusher illustrated is the use of a curved jaw plate on the swing jaw which renders the crusher non-choking.

Introduction: Jaw crushers are powerful machines that are widely used in the mining, quarrying, and recycling industries. These machines are designed to crush large rocks and ores into smaller pieces for further processing. A jaw crusher consists of a fixed jaw and a movable jaw, with the latter being driven by an eccentric shaft that moves the …

Blake Crushers are Jaw Crushers with a movable jaw pivoted at the top, giving greatest movement to the smallest lumps. The throw of Blake jaw crushers is determined by the hardness of the ore as well as the size of the machine. It may vary from d in for hard but friable ores to 3 in for resilient material.

A jaw or toggle crusher consists of a set of vertical jaws, one jaw being fixed and the other being moved back and forth relative to it by a cam or pitman mechanism. The jaws are farther apart at the top than at the bottom, forming a tapered chute so that the material is crushed progressively smaller and smaller as it travels downward until it ...
