Construction projects are common nowadays, and they entail processing rock, gravel, and other products. This means you need high-quality equipment to crush the rocks and increase efficiency. A rock crusher is a leading equipment used, and picking the correct one can be daunting.
The development in technology has made it easy to find a small rock crusher with a touch of a button. Below we discuss all you should know about rock crushers.
Rock Crushing Stages
Most people use different crushers within projects and create them as stations to reduce the required work material. Primary crushing can sufficiently reduce your needs because not all projects need the complete stages. Below are the different crushing stages.
- Primary Crushing
Primary crushing is the initial crushing stage, and it reshapes material to a shape and size to be handled by secondary crushers. The majority of primary crushers have a minimum set of at least 5 to 6 inches.
- Secondary Crushing
Reduction ratios are an essential consideration in secondary crushing. Factors like knowing how you want the final product to determine the reduction in this stage. Cone crushers are put in secondary crushing because of their versatility.
However, it will help to operate these cone crushers using consistent settings to keep them productive.
Types of Rock Crushers
Today, examples of the most famous aggravate in construction fields are limestone, sandstone, and gravel. However, the rocks have dissimilar hardness and characteristics. Below are the types of rock crushers;
- Jaw Crushers
Jaw crushers are primarily used in the primary crushing stage because they are blunt compared to other crushers. They are also called rock breakers, and they break harder materials into small ones. These crushers are compatible with different material types and do not show too much wear.
Jaw crushers also emit minimal dust and fine materials. However, their end product must always go through secondary crushing.
- Gyratory Crushers
These crushers have a concave surface and a conical head. They break material apart via compression. All this occurs via an eccentric movement. Gyratory crushers are mainly used in primary stations, even though they might be secondary crushers.
- Cone Crushers
Cone crushers almost resemble gyratory crushers. They work by compression, meaning they squeeze materials till they break, thus reducing them.
These crushers are designed with a rotating mantle that resembles gyratory crushers. They break hard feeds, but they should be wet.
- Impact Crushers
Impact crushers include HSIs and VSIs. These crushers work best when used with non-abrasive rocks. Impact crushers split material apart into finer consistencies. These crushers are less expensive than others and have a better reduction ratio.
Impact crushers also split sedimentary rocks, producing a sand-like result. However, these crushers’ setback is that they produce excess dust when mixed with soft rocks.
Every construction site needs a rock crusher to make work simpler. These crushers have many advantages and are easy to find. The above article has discussed all you need to know about rock crushing.
