An Essential Guide for Selecting Jaw Crusher 

by John Heine Foundry Shop

When it comes to finding the right kind of primary crushers in Australia, select the one that performs the best operation on the material to be crushed. Apart from the material, consider the feed size, the product size, and the desired capacity required.   

The prime objective of a crusher is to reduce the large components like rocks or ore lumps into smaller and fine size particles. A jaw crusher is a piece of equipment that satisfies all the requirements of reducing material size. Depending upon the industry requirements and operations, the jaw crusher crushing process can include primary, secondary and tertiary stages for reducing gravel, sand, or minerals size. More importantly, it is flexible for many tonnes of production.   

Importance of Jaw Crusher   

The jaw crusher or rock crusher perform essential industry operation such as breaking the biggest and hardest materials like coal, ores, and coke into small and more manageable components. Because of its tiny physical size - it is ideal for tight spaces like underground mining and remote crushing usage where another primary crusher doesn’t fit. It is good to get a small jaw crusher for sale Australia because it offers numerous advantages, including:  

  • Capable of handling variation of materials from hard granite to reclaimed asphalt pavement (RAP).  
  • Minimal dust waste.  
  • Environment friendly.  

Working of a Jaw Crusher  

Based upon the operation, different jaw crusher performs various functions. However, how they work is almost the same across the board. The Jaw crusher performs a compression action to reduce large-sized rocks ore. This jaw crusher is mounted in a V-shaped alignment where one side is fixed while the other is movable. The operator forces the materials into the feed against the stationary plate to perform the crushing operation.   

The empty space at the lower part of the V-adjusted jaw plates is the output gap that specifies the size of the crushed product from the jaw crusher. The stone stays in the jaws until it is reduced to the point where it can pass simply through the gap.  

Main Types of Jaw Crusher   

Jaw crushers have been around since the industrial revolution, and it is one of the most used crusher types. However, since its inception, it has gone through several technological advances which make it more durable and enhance its operational speed. In addition, the structure and design tweak over time, and now it has become an efficient machine that can never be obsolete.

Here are the two types:  

Double Toggle: It is one of the popular choices for crushing tough and large abrasive rocks as well as sticky feeds. Double toggle, also called Blake type, has high energy efficiency and can reduce wear and tear on crusher parts.   

Single Toggle: Unlike double toggle models, the single toggle movement jaw crusher could not handle huge feed sizes, even though it often runs faster. However, now modern technology has helped solve the problem of feed size, and the machines are renowned for the speed at which they function. It experiences more use and tear than double toggle crushers, but the good parts its manganese wear plates are readily accessible and affordable.



For selection of the jaw crusher regarding industrial applications, it is governed by the size of the material, volume and properties of bulk material, along with desired output.
