JW Bell CRUSHING EQUIPMENT
Material handling, mineral and aggregate processing, mining, and recycling plants usually crushers to lessen the size of their raw materials. As a result, they can produce sellable sizes of raw material, making crushers a vital part of the material handling process.
Choosing a Crusher
When choosing a crushing unit, there are some factors that you need to consider to ensure you have the right equipment that suits your requirements. Some factors to consider include:
• The dimensions.
• The abrasiveness and hardness factor
• The capacity
• Granulometric requirement
The HSIs (horizontal shaft impactors) and the VSIs (vertical shaft impactors) are available in two types. They are best for less abrasive raw materials like limestone crushing. 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 product will be more refined with a cubical shape. Compared to jaw and cone crushing systems, impact crushers are 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 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.

Stationary or portable configurations
The TEREX cone crushers are equipped with a revolutionary design that can handle crushing even the toughest materials. These crushers cost less to operate, while producing a higher quality product.
Typically, this grinder 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.
Also known as a rock breaker, it is usually used for breaking hard and large raw materials into smaller pieces that 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 minus the tear and wear that comes with other crushers. The end product of these systems contains minimal marketable materials; hence, the need for secondary crushing.
Heat treated shafts

Breakers & Booms
Stationary rock breakers are designed to help rake rocks into the crusher, clear jams and reduce oversized material entering the crusher.
In such a case where you require a jaw crusher, the crushed raw material usually proceeds to the secondary grinder. The material is further reduced 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 must be of manageable sizes. Therefore, crushing is crucial to the entire process.
