Impact Crushers Versus Cone Crushers: What You Should Know

Stay Connected

Crushers are invaluable tools in various industries across New Zealand, including the mining, recycling and construction industries. There are different types of crushers, and it’s essential for you to select the correct kind for your worksite. 

Impact crushers and cone crushers are popular choices for NZ worksites. Both can crush larger materials into smaller, more manageable sizes. Which crusher works best for you will depend on factors such as the materials you want to crush, the kinds of crushing you need and so on. 

What Are Impact Crushers?

Impact crushers are crushers that are mainly used for secondary and tertiary crushing, but heavy-duty impact crushers can also be used for primary crushing if used correctly. They use high-speed force to break down materials and are generally more easily adjustable and versatile than cone crushers. 

They can produce high-quality, uniform particles and are often selected for specific applications, such as creating road materials. 

Both impact and cone crushers can handle harder substances, but impact crushers are often used for both harder and softer materials. When using your crusher, be sure you use the right settings for the hardness of the material you want to crush. Settings that are too powerful may create finer particles than you’d like, and settings that are too weak may be insufficient to break harder minerals. 

What Are Cone Crushers?

Similarly to impact crushers, cone crushers are used to break larger materials down to designated sizes. Cone crushers are more often used for secondary and tertiary crushing.

Cone crushers use compression to break materials down. This is where the material is reduced by being crushed or compressed between two surfaces, a rotating cone and a stationary bowl, letting the resulting smaller particles fall through the opening below the surfaces.

Cone crushers are primarily used to create aggregates from hard, abrasive materials like granite and basalt. They produce consistent particle sizes for industrial applications. 

One issue that cone crushers often face is a high content of fines. Fines and other unwanted materials in the infeed can cause materials to become packed into the crushing chamber, causing poor product quality and potential damage to the cone crusher itself. So, it’s advised to use a pre-screen process to remove the fines before materials are fed into the cone crusher. If you plan on getting a cone crusher, you may also want to look into purchasing or hiring a screener as well.

Impact And Cone Crushers: Which Is Right For Your NZ Worksite?

Both impact and cone crushers have their advantages. As with any other kind of tool or equipment, you will get the most out of your crusher when you use it properly and select the right one for your specific needs. 

Make sure you think about the following before you choose your crusher:

  • The Material You Want To Crush. What materials will you be working with? Cone crushers are generally used for harder materials like iron ore and may not be suitable for softer substances. Impact crushers, on the other hand, can be used for any kind of hard or soft material as long as you use the correct settings. Be sure you understand the kinds of materials you need to crush before you purchase your new crusher. 
  • Primary, Secondary Or Tertiary Crushing? What stage of crushing do you need?
    • Primary. Primary crushing is the very first stage of crushing. This involves taking raw materials that were mined, reclaimed or blasted and then running them through a crusher to break them down into smaller sizes. Sometimes, this is the only level of crushing you need.
    • Secondary. Secondary crushing occurs after primary crushing. Once the materials are broken down by the primary crusher, they are fed back into a crusher again. Secondary crushing produces more uniform sizes compared to primary crushing. 
    • Tertiary. If materials still need to be broken down after secondary crushing, then tertiary crushing will occur. This is when materials are broken down into even smaller, more uniform sizes.
  • Your Budget. Managing your finances is an essential part of being a successful businessperson. Consider how much money you can afford to spend on your new crusher, and think about whether you want to purchase or rent your equipment. If you decide to purchase your crusher, look into your equipment’s maintenance requirements and plan to stick to a maintenance schedule. Keeping your crusher in good condition will reduce schedule-disrupting malfunctions and increase its lifespan.
