Jaw Crushers is a type of equipment frequently used for reducing the sizes of various materials and for several applications. The first Jaw-Crusher was introduced in 1858 by Eli Whitney Blake and was known as the double-toggle JawCrusher. In 1906, the McLanahan’s Universal Jaw Crusher was first introduced and was among the first of the Overhead Eccentric Jaw Crushers.
With the overhead-eccentric style Jaw Crushers, the swing jaw that moves is attached and suspended on an eccentric shaft, which includes double-roll heavy-duty, spherical-roller bearings. The jaw that swings undergoes two motion types. The first is a swinging motion that travels toward an opposite chamber (known as the stationary-jaw die, which is caused by an action made by the toggle plate). The second movement is a vertical motion caused by the rotating movement of an eccentric. The combination of these motions pushes and compresses materials through a crushing chamber until they reach the predetermined size.

How Does The Jaw Crusher Philippines Work?
Jaw Crusher Philippines use a compressive force for breaking materials. This is a type of mechanical pressure that is made possible by the crusher’s jaw dies. One of these is movable while the other is stationary. The two manganese vertical jaw dies are designed to create a cavity in a V-shape which is known as the crushing chamber. The top part of this chamber is bigger at the top than it is at the bottom.
The Jaw Crushers are sized according to the opening at the top of the chamber. For example, the 32 X 54 Jaw Crusher Philippines, will measure 32″ from the one jaw-die to the other jaw-die from the gaping opening or the top opening and 54″ across the entire width of the 2 jaw dies.
The opening at the bottom is narrower in a crushing chamber and is typically used for sizing the discharged materials. The tension rods and the toggle plate hold a pitman tightly in a position close to the bottom part of the swing jaw. The toggle plate acts similar to a fuse and also protects the crusher if any uncrushable materials have entered the chamber.
Sizes of Jaw Crusher Philippines
In most cases, Jaw Crusher Philippines have either an 8:1 ratio or 6:1 ratio when it comes to crushing materials. Going back to the same example as the 32 X 54 Crusher, the size at the top of the feed that enters the crushing chamber must follow what is known as the F80 rule. This means that 80% of the overall size of the materials fed into the top has to be smaller than the top opening. With the F80 rule with a 32 X 54 Jaw Crusher Machine, the gaping opening of 32″ is equal to a 26″ top-sized feed. With the 6:1 ratio-of-reduction, the setting for discharge would be about 4″.
