jaw crusher that employs the simple technology of a four bar mechanism, and design a small scale mechanized jaw crusher for crushing the stones into aggregates. This mechanism will help to evaluate its effectiveness in comparison with other different types of mechanisms in use especially the double toggle and the modified single toggle mechanism.

Abstract- In this paper alternate mechanism for design and analysis of small size stone crusher mechanism is proposed. The basic ... 2.1) Crank and lever Mechanism 2.2) Double Rocker Mechanism. 2 ...

The crusher mechanism requires that the crank (r) rotate at a constant velocity, and the advance part of the cycle is to take 1.5 times as much as the return part. The distance between fixed pivots A* and B* must be 4 ft. Determine the lengths for r2, 13, and 14: 40 …

crank rocker mechanism, is a one of inversion of four bar mechanism.It satisfy Grashof's Law. That is sum of length of shortest and longest links is less...

The first crusher was a simple swing jaw crusher in 1858 (Fig. 1). It is a crank double-rocker mechanism, so-called "simple pendulum" is not because of its simple structure, but because this crusher moving jaw (The Rocker of the mechanism) around the suspension point for a simple swing become well-known.

4.1.2. Dead-Centre Positions of Crank-Rocker Mechanisms In crank-rocker mechanisms the rocker oscillates between two limiting angles (In general, the crank is the input and rocker is the output). The positions of the mechanism when the rocker is at a limit position are called the dead-centre positions of the four-bar. We can also define the ...

Transcribed image text: 4 ft Problem 2. Using Grashof Chain analysis for a 4-bar linkage, determine whether this linkage is a crank-rocker mechanism. Graphically sketch the position of the links for the stone crushing mechanism shown into the two configurations that place the crusher plate CD in its extreme limiting positions (Assume the wall with stones is removed).

Rocker: Any link which does not revolve is called a rocker. Crank-rocker mechanism: In a four bar linkage, if the shorter side link revolves and the other one rocks (i.e., oscillates), it is called a crank-rocker mechanism. Double-crank mechanism: In a four bar linkage, if both of the side links revolve, it is called a double-crank mechanism ...

Jaw crusher's drive mechanism is a typical crank rocker. It is cheap and easy to be made. And its structure is simple. But the jaw crusher has the congenital defects that the lower part of the movable jaw is in "reduced power" status, and the whole machine is "half for power".

As Fig. 1 shows, the crusher breaking part is comosed of differential teeth and a crank-rocker mechaism. A sketch of the moving jaw crank-rocker mechanism is shown in Fig. 2. In a search for optiization designs of a crank-rocker mechanism, it seems that much of the literature consulted aims only at optimizing the transmission angle ..
