What are the Different Types of Concrete Crushers

What are the different types of concrete crushers?

  1. Jaw Concrete Crusher
  2. Impact Crusher
  3. Cone Concrete Crusher
  4. Gyrator Crusher
  5. Roller Crusher

Before rolling in bulldozers, cranes, and other forms of heavy-duty equipment, materials need to be crushed and ready for you. This important task is left to a concrete crusher. 

Crushers are used to reduce the size of raw materials like rocks and stones. It is classified into two types of categories: primary and secondary crusher. A primary crusher is used for heavy-duty materials while secondary crushers break down small to medium-sized rocks. 

Even with these two categories, many are still asking: what are the different types of concrete crushers? This article discusses the common types of concrete crushes and what kind of material it’s suited for and what is produced. Keep reading to learn more!

Jaw Concrete Crusher

A jaw concrete crusher is one of the larger-scale pieces of machinery in construction. It is considered heavy-duty since it is usually constructed with cast iron or metal, making it incredibly strong and hard-wearing.  This is often used to break down rocks into non-uniformed gravel. 

Think of a jaw concrete crusher as a nutcracker. It uses leverage to amplify the pressure. Huge amounts of material are fed into a v-shaped funnel. This is the jaw of the crushes that reduces rocks by compressive force. One side of the jaw is stationary while the other swings. 

The jaws create a chewing motion as it opens and closes vigorously. This can be done because of its heavy flywheels powered by diesel or electric motors. As the crushing continues, materials are forced to the narrowest point of the machine. The tapered shape at the end of the jaw only allows small and crushed materials to pass through. 

This crusher is a popular choice in the construction industry since it can produce soft to hard materials. 

Impact Crusher

Impact Crusher

An impact crusher is responsible for reducing various mineral materials like natural rocks, concrete, and asphalt into precisely shaped products. It has two types: a horizontal shaft impactor (HSI) and a vertical shaft impactor (VSI).

The two types of impact crushers differ in the kinds of materials they can crush. The HSI can only accommodate soft materials, so it is not suited for crushing concrete. Instead, soft sedimentary rocks are what’s passed through this type. On the other hand, the VSI can accommodate harder materials because of its high-speed rotor. 

It consists of an enclosed rotating cylinder that is responsible for breaking down materials. This crush can break materials by striking the rocks with its high-speed rotating impact. This creates a shearing force on the rocks put into the machine. 

As the materials reach the rotor, the debris is caught by either steel teeth or hard blades that are attached to its rotor. They are then hurled against a breaker plate that smashes the debris into even smaller pieces. 

Cone Concrete Crusher

Among secondary crushers, this is the main choice of many demolition professionals. A cone concrete crusher is suitable for breaking down both medium-hard and hard materials. It can produce very fine end products like backfill material and fine sand. 

This crusher consists of a central cone that points upwards. This cone quickly spins against a mantle and an outer crushing surface. Materials are reduced to fine pieces as it is squeezed in between the mantle and the cone’s concave shape. The pieces get smaller until they can fall to a lower position in the cone. The process then repeats itself until the desired product is produced. 

This cone crusher is proven to be reliable especially when companies are looking to reduce their costs. 

Gyrator Crusher

A gyrator crusher is used when construction companies want to produce more uniform-shaped products. It can also be used for large amounts of materials. 

This crusher consists of a solid cone set that is set on a revolving shaft. It is placed with a hollow body that has vertical or conical sloping sides. 

As you put in the materials, the machine brings the two crushing surfaces together. The two surfaces approach each other to crush the materials inside. This process repeats until the materials are crushed to the desired shape. The products then fall through the discharged opening. 

Compared to the jaw crusher, a gyrator crusher creates products faster while using less power. 

Roller Crusher

A roller crusher is primarily used to deliver fine material output. It is not meant to be used with hard and abrasive materials. 

This machine consists of cylinders that are mounted horizontally. One cylinder rests on strong springs while the other is stationary and permanently framed. For longevity, the cylinder is lined with manganese. 

The materials are fed in between the two cylinders. To produce fine material, a roller compressor makes use of compression. They are compressed together until the desired material output is created. They have separated away once the output is produced. 

Key Takeaway

Now that you know what the different types of concrete crushers are, you can assess what type is best suited for you and your project. Each type of crusher can handle different kinds of materials and produces specific output.
