Primary crushers play an important role in a mineral processing plant. It helps reduce the size of large rocks , and smaller pieces are sorted through a range of site components , such as belts, screens and secondary crushers to get the result you want. Almost all of the components at a crush site rely on the primary crusher, which is why it vital to choose the correct one for the needs of your business.


These guidelines will assist you to identify which type of primary crusher will work best for your aggregate projects. Let’s begin with the goal and then move on to refinement of the model. Finally, we will install the primary crusher.


Identify the purpose of the primary crusher.


The first step in selecting the appropriate crusher liners is to figure the intended purpose of its use. This is the first step in making a decision and could take some time and some guidance. You must determine the type of material and the dimension of the crushed material.


Also, you should take into consideration the moisture content of the material, target production amount as well as the discharge quality and long-term site strategy. To better understand the purpose of each primary crusher, let’s take a look at them all.


Jaw crushers


The jaw crusher is the most common crusher used in mineral processing facilities. It’s comprised of two jaws that form an “V” alignment where one side is fixed and the other moves to crush large rocks and then break them down into smaller pieces. It’s portable and is easy to relocate into other processing plants when required. Jaw crushers are great for crushing abrasive material.


Jaw crushers make some of the hardest materials around because the rock is broken by their inherent lines of weakness. Jaw crushers are a great primary crusher for preparing materials to be further processed.


Gyratory crushers


Gyratory crushers are great for the production of large quantities of material (which typically amounts to 1,000,000 tonnes per year). The basic principle behind these crushers is the same as jaw crushers, but instead of utilizing an “V” alignment they utilize a circular gap. The crushed material is pressed between an oscillating mantle as well as a fixed conical box. Gyratory crushers are able to reduce the size of rocks that are granular such as granite. They can also tolerate large amounts of feed particles like slabby rocks (which jaw crushers cannot accept because of its shape).


Impact crushers


The impact crusher works by pushing the feed material against the plates. This reduces its size. These crushers can process limestone in a more efficient manner than other types.


When the material’s shape is important, impact crushers can be used. Impact crushers are used when the shape of the material is critical. Impact crushers come with a drawback that they may cause high long-term wear costs.


The most significant characteristics of a machine is its capability and capacity to process materials without obstructions. Larger primary crushers are expensive, and it is important to calculate the investment cost to determine the size of crusher needed to crush materials to a smaller size.


Examining the function and fit of the primary crusher


After you’ve decided on the kind of crusher you’d like to use, it’s time to evaluate the crusher’s performance. Simulations are a fantastic instrument for this. Simulations are a great way to predict the way that crusher liners will function, and the impact it has on the load downstream. There are many software applications that simulate the aggregation process which will give you a clear picture of the crusher’s performance.


A simulation can influence crusher recommendations based on results. If you have long-term plans then it’s better to use a stationary model than a portable one. From there, a concept drawing is drawn that includes details of the site of crushing, such as grade elevation and the topographical map.


Concept drawings will give you an idea of how the primary crusher will integrate with other elements on the site. New primary crushers generally require changes to conveyors and screens to improve their capacities.


Correct installation of the primary crusher


The final step is to make sure that the primary crusher is installed correctly. The process can be complicated and confusing, depending on the situation. To ensure a successful installation, contact your manufacturer and request technicians to help with the installation. From the project management through the performance verification A skilled technician on hand to assist you can provide you with more assurance and will optimize your site configuration from the beginning.
