What Is a Rock Crusher Used For?

A rock crusher is a device used to crush rocks into pieces of your desired size. Rock crushers are most often used for gravel, sand, and other building applications. Some of the most common types of aggregates in rock crushing are sandstone, gravel, and limestone. The type of rock you plan to process will dictate the type of rock crushers you will need.


How Do Rock Crushers Work?

On the job site, rock crushers help automate the size reduction process. Most rock crushers use a container known as a hopper to hold the rock. Then, gravity feeds the rock into the crusher where it is reduced. A belt feeder can also be used to constantly feed the rock into the crusher.

Once in the crusher, rock is pressed into smaller pieces that fit through a hole. Once reduced, materials exit the crusher onto a conveyor belt, a bin, or a large pile.


Different Types of Rock Crushers

It is common to use multiple rock crushers on a single job to accomplish the different goals of your production needs. Primary, secondary, and tertiary crushers can all be used to help you find the desired size of your final product. Primary crushing starts by extracting your original material and is then followed by crushing to reduce the size.

In some applications, primary crushing alone can suffice. However, primary crushing is often followed by secondary crushing and tertiary crushing. Secondary crushing and tertiary crushing work to reduce your material down to the exact size needed. The fineness of your final product determines how many stages of reduction you will need.

Williams Crusher has a variety of rock crushers to help you meet any size reduction need.


Does the Type of Rock Crusher I Use Matter?

The type of rock crusher you use depends on what you want for your final product. Crushing may take place in one process with a single crusher. However, secondary, and tertiary crushing can be used to break your material down to the right size. Many rock crushing plants have multiple rock crushing stations set up to make a complete rock crushing production.
