Did you know that there are different types of crushers? There are several types, each with unique features and benefits.
So, if you’re in the market for a crusher, you must understand the different options available to you. Here is a quick overview of the four main types of crushers: jaw crushers, cone crushers, impact crushers, limestone crushers, and hammer mills.
Which type of crusher is right for you? Read on to find out!
Types Of Crushers
1. Jaw Crushers
Jaw crushers are one of the most commonly used types of crushers due to their versatility. They are suitable for crushing various materials from soft to hard and are therefore also referred to as compression crushers.
In terms of operation, jaw crushers work by compressing materials between two opposing plates, one movable and the other stationery. The force created by the compression action serves to break the material into smaller particles, which can then be discharged from the bottom of the machine.
Jaw crushers are typically used in quarrying and mining applications but can also be found in demolition sites and recycling facilities. In terms of capacity, jaw crushers can process up to 1,600 tons of material per hour.
2. Cone Crushers
Cone crushers are types of crushers that are generally used in mining, aggregate production, and construction. A cone crusher must have the right crushing chamber and an eccentric force-generating mechanism to crush rocks or ores effectively.
The most common type of cone crusher is the Symons cone crusher, which has been designed for use in secondary or tertiary crushing applications. The main difference between the two is that a Symons cone crusher is designed to crush hard rocks and ores, while an impact crusher is more commonly used for softer materials such as limestone.

3. Impact Crushers
Impact crushers are types of crushers that use force to break down materials into smaller pieces. The force is applied by using a rotating disk that strikes the material as it is fed into the crusher. This crusher type is often used in recycling operations, as the materials broken down by the impact of the disk are often recycled materials such as metals and glass. Impact crushers can also break down materials such as concrete and asphalt.
These crushers are typically used for jobs that require less power than a jaw or cone crusher, and they are often used in situations where there is a danger of over-crushing, such as with rigid materials.
4. Hammer Mills
Hammer mills are types of crushers that grind the material into smaller pieces with repeated blows of hammers. The advantages of using a hammer mill are that it is energy efficient, can be operated manually or automatically, and is versatile. The disadvantages of using a hammer mill are that it produces dust, creates noise, and can be dangerous if not used properly.
A hammer mill is most commonly used for grinding corn, but it can also be used to grind other materials such as wheat, rye, oats, barley, and rice. The material to be ground is placed in a hopper at the top of the machine, and the hammers grind the material as it falls through the opening at the bottom of the hopper.
The size of the finished product can be controlled by changing the size of the screen at the bottom of the hopper. Hammer mills are available in horizontal and vertical designs and can be powered by electricity or gasoline.

What Are The Different Types Of Crushing?
1. Primary Crushing
Primary crushing is the first stage of material reduction and can sometimes be the only crushing stage in the process. It typically takes place before secondary crushing and is performed using jaw or gyratory crushers.
Primary crushing reduces the material to a size that secondary or tertiary crushers can further process. In some cases, it may also be necessary to use rock breakers to reduce the size of the material even further. Depending on the desired outcome, primary crushing can be essential to achieving a successful result.
2. Secondary Crushing
Secondary crushing is the second stage of rock crushing or the second granularity process of comminution after primary crushing and is mainly to produce fine particle product. Unlike primary crushing, secondary crushing involves more than one distributor and screening machine in a closed-circuit system.
To satisfy users’ various needs, two or three-stage complete comminution circuits are available for secondary smashing, such as cone crushers, counter-attack crushers, vertical impact crushers, and other equipment, so that a variety of different types of medium and small-scale complete sets of the production line equipment can be provided. According to the need of customers, various types of equipment combinations can be designed and manufactured.

3. Tertiary Crushing
Tertiary crushing is taking already crushed material and reducing it to a smaller particle size. This can be done through several different methods, such as impact crushing or compression crushing. Tertiary crushing is often used in conjunction with other forms of comminution, like primary crushing and secondary crushing, to achieve a complete reduction of the raw material.
Tertiary crushing typically produces a finished product that is either sand-sized or gravel-sized, depending on the feed material and desired particle size. Tertiary crushing can be very beneficial in increasing the overall efficiency of a comminution circuit, as it can provide a final product that is easier to transport and handle.
