How Do You Choose The Right Primary Crusher?
Primary crushers play an important role in a mineral processing plant. It reduces the size of large rocks wherein the smaller pieces are processed through a range of site components , such as belts, screens and secondary crushers to achieve the desired outcome. A majority of the elements of a crush site depend on the primary crusher. It is essential to choose the correct one to meet your requirements.
These suggestions will help you to determine the primary crusher that is best to suit your particular project. Let's start with the purpose before proceeding to refinement of the model. In the end, we'll install the primary crusher.
Define the reason for the primary crusher.
The first step to choose the best shredder parts is to figure the intended purpose of its use. This will inform the entire selection process and might require some direction and experience to get the best results. The two key components to consider are the type of material used and the size of the feed to be crushed.
Other factors worth considering are the amount of moisture in the material, targeted production capacity, discharge gradation, and the site's long-term strategy. To better understand the purpose of each type of primary crusher, let's look at all of them.
Jaw crushers
The standard jaw crusher is the primary crusher utilized in mineral processing plants. It's made up of two jaws in the form of a "V" alignment , where one side is fixed and the other is moved 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 ideal for crushing abrasive material.
Jaw crushers create the most rough materials since they break the rock along its natural lines of weakness. Jaw crushers make a fantastic primary crusher to prepare materials to be further processed.
Gyratory crushers
Gyratory crushers can create large quantities of material, generally about 1,000,000 tonnes annually. The basic principle behind these crushers is similar as jaw crushers but instead of using the "V" alignment they utilize circular gaps. The material is compressed between a conical fixed bowl and an rotating mantle. Gyratory crushers are able to reduce the size of granular rocks like granite. They can also tolerate large amounts of feed particles, such as slabby rocks (which jaw crushers cannot take due to the shape).
Impact crushers
The impact crusher functions by pushing feed material into the plates. This decreases the size of the crusher. These kinds of crushers are effective in processing materials like limestone with better form than the mentioned crushers.
Impact crushers are employed for when the form of the material is a critical necessity. The crushing action breaks the material in its natural cleavage planes which results in better product quality , in terms of shape. Impact crushers have a downside that they may cause significant wear costs over time.
The capacity of the primary crusher as well as the capacity to take in material without blockages is among the primary characteristics of the equipment. The larger primary crushers are typically more costly, so it is essential to calculate the cost of investment to determine which crusher is needed to blast materials down to a smaller size.
Examining the function and fit of the primary crusher
After you've chosen the type of crusher you'd like to use, it's time to evaluate the crusher's performance. Simulations are where they are essential. Simulations are essential to know how the shredder parts will function and how its performance will affect the load downstream. There are a variety of software applications that allow you to simulate aggregate production and give you an understanding of the crusher’s actual performance.
Running a simulation may influence crusher recommendations based on results. If you have long-term plans, it is better to use a stationary model than one that's portable. After that, a concept drawing is drawn that includes the details of the site of crushing, such as the elevation of the site and the topographical map.
Conceptual drawings can provide you with an idea of how the primary crusher can be integrated with other elements that are on the site. New primary crushers generally require updates on screens and conveyors to improve their capacities.
Correct installation of the primary crusher
The last step is to ensure the primary crusher is properly installed. The procedure will differ based on the context and can sometimes prove difficult and confusing. For a successful installation make contact with your manufacturer to request technicians to help with the installation. A skilled technician will assist you right from the beginning, optimising your site layout and the management of your project.
