JW Bell CRUSHING EQUIPMENT 2021

Material handling, mineral and aggregate processing, mining, and recycling plants usually use crushers to lessen the size of their raw materials. As a result, they can produce sellable sizes of raw material.

In material handling, crushers usually play a vital part in the entire process. Once you collect the raw material from the grinder, the first two steps will involve the grinder equipment. The following text will help you understand more about the crushing equipment.

What is Crushing Equipment?

Typically, this equipment helps reduce the enormous sizes of raw materials into sellable sizes depending on the usage purpose. They are usually heavy machinery.

Additionally, this equipment consists of heavy jaws and plates that help apply pressure to the raw materials fed through the chamber. Irrespective of the size, all crushers come with a complete material handling system.

In most mineral processing and rock quarries operations, you are likely to find several types of equipment like screening machines, crushers, and conveyors. All these systems help in creating marketable raw materials.

How does the Equipment Work?

The significant elements of the equipment are durable jaws and plates forming the heavy chamber. First, the raw material is channeled to the grinder. Once the raw material is fed, the plates will apply pressure, reducing it into smaller sizes. The plates usually operate by moving up and down during the crushing process.

To reduce the fed materials further, you can incorporate multiple crushers. However, it is essential to note that some crushers can’t handle large materials. For this reason, be sure to have the heavy-duty pounder as your first step in the plant circuit. For instance, a jaw crusher is ideal for handling large pieces before feeding them into the smaller crushers.

In such a case where you require a jaw crusher, the crushed raw material usually proceeds to the secondary grinder. The material is reduced further in the secondary grinder before getting into the screening system through a conveyor belt.

However, for the crushed material to get into the screening machine, they have to be of manageable sizes. This makes the crushing process a crucial process in the whole process.

How to Use a Crushing Equipment?

Usually, the equipment is the first stage for most material production, jobs, and handling plants. However, your equipment typically depends on the type of raw material.

Although all crushers operate nearly the same, the final product is used in different ways.

Some of the industries that use crushers include:

• Mineral processing
• Mining
• Recycling
• Rock quarries

The quarrying and mining industries are the areas where equipment is mainly used. Turning these raw materials into marketable sizes is an extended handling system that is vital.
To create a sellable final product, you also require to incorporate other machines with your crusher

 

The whole process starts with feeding the grinder then the screening process, where the end product is separated. The end product could either be winterizing salt, road gravels, among many more.

Additionally, crushers are also vital equipment in the recycling industries as they help break down containers and glass bottles. Once the pounder reduces the size of the glasses or containers, they are processed into the melting unit. Once melted, they can then be of use in making other containers..

Jaw Crusher

Also known as rock breaker. It is usually for breaking hard and large raw materials into smaller pieces ideal for smaller crushers.

 

Typically, this equipment creates final products by compression. Compared to other equipment, jaw systems are usually blunt instruments. This makes them ideal for the primary crushing stage.

 

In addition, these systems function well with various raw materials without a tear or wear as other crushers. The end product of these systems contains minimal marketable materials; hence, the need for secondary crushing.

Cone Crusher

Typically, this grinder type is a rotating mantle housed in a bowl-shaped structure usually lined with manganese. The crushing chamber is relatively steep.

 

The working principle of this system is similar to that of jaw systems, where they reduce the size of raw material through compression. This implies that they apply pressure to the fed materials until they break. Generally, you can feed these crushers with abrasive and medium sizes pieces for the crushing process.

 

The feeds can be wet or dry; however, they should not be sticky. Their end product is usually relatively cubical with an excellent reduction ratio.

Impact Crusher

The HSIs (horizontal shaft impactors) and the VSIs (vertical shaft impactors) are available in two types. They are best for limestone crushing and other less abrasive raw materials. They work by applying the impact toggles and blow bars forces to break the feed materials.

 

To produce more elongated products, you can use these crushers as a secondary crushing unit. As a result, the results will be more refined, with a cubical shape. Compared to jaw and cone crushing systems, impact crusher is usually less costly. They also have a significant reduction ratio. You can also use this type of grinder to break sedimentary rocks to produce a sellable end product.

 

However, these type of crushers has the disadvantage of creating a sand-like end product, especially with soft raw materials. They can also need regular parts replacements. Another drawback of these crushers is that they generate considerable dust, resulting in a challenging workplace.

Gyratory Crusher

Like the jaw crushing system, this concave surface and conical head grinder are ideal for primary crushing. However, you can apply it for secondary crushing by incorporating it together with the jaw equipment.

 

Gyratory crushers usually break down the fed raw materials through eccentric movement.

When choosing a crushing unit, there are some factors that you need to consider to ensure you have the right equipment that best suits your requirements. Some of the factors to consider include:


• The dimensions.
• The abrasiveness and hardness factor
• The capacity
• Granulometric requirement
