Jaw Crusher Working of the top of the line series
Mechtech’s top-of-the-line MTJ-type jaw crushers are designed specifically for primary applications where resizing is the primary goal. They allow the material to be handled within the confines of your crushing plant. The jaw crusher must have a good and homogeneous feed level to perform optimally.
These single-toggle jaw crushers have a deep, symmetrical crushing chamber, a large feed opening for their size, and an ideal nip angle that provides smooth material flow and high reduction efficiency. Jaw crushers typically have a reduction ratio of 1:2 or 1:3. This ratio is influenced by the bulk density, crushability, size distribution, and moisture content of the feed material,among other factors, and will affect the performance of the crushing chamber
Compressive and rubbing pressures are used in a single-toggle grease lubricated jaw crusher to break material. The two jaw plates of the crusher, one of which is immovable and the other movable, work together to exert this mechanical pressure. The crushing chamber is a V-shaped cavity formed by these two vertical manganese jaw plates, with the top of the chamber being larger than the bottom. Jaw crushers are sized by the crushing chamber’s top opening. A 41″ x 33″ jaw crusher, for instance, has two jaw dies that are 41″ wide and 33″ apart at the top opening, also known as the gape opening.
The discharge material is sized using the narrower opening at the bottom of the crushing chamber. A toggle plate and tension and pull-back rods keep the swing jaw tight near the bottom.
Since the crushing of the material is not performed in one stroke of the eccentric shaft, massively weighted flywheels are attached to the shaft and powered by a motor. The flywheels transfer the inertia required to crush the material until it passes the discharge opening. Generally, the motion of swing jaw is elliptical.
