There are several different rock crusher options, and each is used for slightly different purposes. When choosing a rock crusher for your operations, it’s important to first identify the stage of crushing you’re using the machine for. This will determine the appropriate solution for your needs.
There are three different stages of concrete crushing:
In addition to identifying the proper stage being used with your rock crusher, you should consider the following criteria:
Once you’ve evaluated the criteria discussed above, it’s time to choose a rock crusher that will effectively address your specific applications. Each of the following options will deliver different results and are ideally suited to different stages of the process.
A jaw crusher is a type of compression crusher that is most commonly used for primary crushing. The material being crushed is squeezed between a stationary piece of steel and a moving piece of steel. This produces the coarsest material since the rock is being crushed along its natural lines of weakness. Jaw crushers are effective the hard and abrasive materials such as granite, ores and recycled concrete.
Advantages of jaw crushers include:
Drawbacks to this option include:
As with jaw crushers, these machines are compression crushers that use a stationary and moving piece of steel to break up the material. Cone crushers use a rotating head to crush the rock within a steel bowl. After initially being broken down in this manner, the material will travel through a narrow opening at the bottom of the bowl to achieve a finer grain size.
Cone crushers can be used with a variety of materials, ranging from medium to hard. They are typically used with secondary crushing, especially when the final shape of the crushed material is important.

Drawbacks to this option include:
Impact crushers break down material by leveraging mass and velocity. The material being crushed is hit by hammers. This material then travels towards a metal plate, where the rock breaks apart and bounces back up to be hit by the hammers again. This process continues until you’ve achieved your desired final size.
Impact crushers can be used with all three stages of crushing. While they can handle materials of all hardness, they are ideally suited for soft to medium rocks.
Advantages of impact crushers include:
Drawbacks to this option include:
When purchasing a jaw crusher, you can choose between a stationary option and a portable jaw crusher. Stationary crushers are typically sturdier. However, you’re limited by the fact that it must reside in one place all the time. Mobile jaw crushers, on the other hand, give you the ability to move the machine to the precise location where you need it at all times. For this reason, they often provide a more versatile solution.
