Rock Crushing Solutions in Vancouver
Get In Touch With Us
There are several rock-crushing options available for reducing the size of rocks, stones, and concrete found at a worksite.
If you’re not an aggregate producer by trade, every new job presents its own unique challenges.
With the right rock-crushing solution, you can turn those obstacles on-site into valuable construction materials. You’ll have the base gravel necessary to lay new foundations for roads, bridges, and buildings. However, if the wrong rock crushers are used, it can affect your project’s bottom line and the efficiency of your project.
Rock Crushers: Everything You Need to Know
The most common types of rock crushers fall into four categories: jaw crushers, cone crushers, gyratory crushers, and impactors. All are suitable for primary crushing; however, cone crushers are typically used as a secondary crusher after the material has already been through primary crushing in a different machine.
Primary crushers reduce large rocks and ore into smaller chunks for additional processing. Secondary crushing reduces those pieces even further. Several machines may be necessary to achieve the desired size. There are primary and secondary crushers as well as machines designated for tertiary and quaternary crushing purposes. Multiple crushers can form a circuit for proper size reduction of materials.
There are several considerations that factor into deciding which type of crusher to use for a specific construction project.
- The hardness of the material being crushed
- The desired size of aggregate
- The most suitable size of rock crusher for the location
- Processing capacity (tons per hour)
Does the Type of Rock Crusher I Use Matter?
Jaw Crushers: These machines (also known as “rock breakers”) use compression to crush rocks, stone, and ore, including granite and concrete, between a stationary plate and an oscillating plate. They can be fixed or mobile. They work well for most applications and handle a large feed size while producing minimal dust.
Cone Crushers: Like the jaw crusher, this equipment uses compression. Material is squeezed using a rotating mantle. The eccentric movement crushes rocks against the manganese steel lining the unit’s interior. It is commonly used for intermediate or fine crushing, reducing smaller rocks into gravel or sand.
Gyratory Crushers: This style of rock crusher is similar to the cone crusher, with a conical head and concave surface. However, it is usually used during the first stage of the crushing circuit. These crushers consume less energy than jaw crushers, and their continuous operation lends itself well to high productivity.
Impact Crushers: An impact crusher utilizes striking rather than squeezing pressure to break up rocks. Material is accelerated and flung against the walls of the crushing chamber. These machines work best with medium-hardness materials such as coal, clay, and limestone. Impact crushers also include horizontal shaft impactors (HSI) and vertical shaft impactors (VSI), which are differentiated by the position of the rotor.
Unlike the vertical models, horizontal shaft impactors utilize hammers and bars to crush the material entering the machine. This process allows HSI models to be used as a primary and secondary crushing unit. VSI units work best toward the end of the crushing circuit for creating aggregates of a more workable size.
A company with experience in rock crushing understands which equipment will best serve the needs of the job. From roll crushers to hammer mills, having the right piece of rock-crushing equipment from the onset will save you a lot of time and expense.
Stationary or Portable/Modular Rock Crushers
However, construction teams with multiple jobs on the go and shorter-term projects tend to prefer a portable/modular option that can be transported and set up between different locations.Today’s portable/modular equipment does an excellent job once set up at the site.
Industrial rock crushers are an essential part of the construction industry. Many construction projects require a specific type of aggregate to provide foundational support and reliable infrastructure for the entire operation.
Companies that fail to consider their project’s rock-crushing needs during the pre-planning stage will be setting themselves up for additional costs and delays.
