It is essential to select the appropriate crusher for every task. Knowing the different phases of crushing and the kinds of crushers that work best for the stage makes it easier to select the right equipment. Each crusher type has its own characteristics and is used to produce a specific end result.
Similarly, a certain output is anticipated at the conclusion of each crushing stage to determine the next phase of the process. Aggregate producers who pair the correct shredder parts to the correct stage are the most effective, and in turn, the most profitable.
Crushing stages
Aggregate producers are familiar with selecting crushing equipment. They know that they can select an equipment piece based on specifications and gradation calculations. But, it is crucial to consider the theoretical findings against the actual experience of the material as well as the maintenance, economic, and operational aspects of various options.
The process of reduction usually takes place in stages. While there are single crusher alternatives, the most well-known systems have at minimum two or more crushing stage.
Primary crushing. Primary crushing is the process used to make it possible to move material via a conveyor belt. In most aggregate crushing plants the primary crushing process is performed in a jaw crusher, although a gyratory primary crusher could be utilized. If material is easily crushed and not excessively abrasive an impact crusher could be the best choice.
The primary aspects of the primary characteristics of a shredder parts the most important are its capacity and the ability to accept raw materials without any obstructions. A large primary crusher is more costly to buy than a smaller machine. This is the reason why primary crusher investment costs are assessed against the expense of blasting raw materials to a smaller size.
Trucks transport material from one place to another. The costs of fuel, tires, maintenance and return on investment need to be taken into consideration.
A pit-portable primary crusher may be a viable option in cases where the producer is crushing on the quarry face. In modern plants it is usually advantageous to employ a moveable primary crusher, so that it can be able to follow the motion of the quarry's face, where the raw material is extracted.
Intermediate (secondary) crushing. Intermediate crushing is utilized to create coarser fragments and prepare the material for final crushing. The quality of the product is crucial when the intermediate crusher is to be used to make railway ballast.
In other cases, there are no requirements for quality, but the product should be suited to fine crush. The objective is typically to achieve the lowest cost and the highest reduction.
Fine crushing (tertiary). In this crushing phase, the quality and quantity of fine-quality products are established. Quality requirements can be stringent for final products, specifically in the aggregate industry.
In most instances, the fine crushing and cubicization processes are combined into a single crushing stage. The choice of a crusher for tertiary crushing calls for both practical experience as well as theoretical knowledge. That's why producers must ensure that they contact an experienced application specialist to ensure that the device is well-engineered.
Crusher types
Jaw crushers. Jaw crushers are type of compression crusher. It can reduce the size of material by pressing it between two pieces of steel. The setting, or the distance between the two pieces of steel, controls the discharge size. The setting is tighter that results in a smaller output size and a lesser throughput capacity.

Jaw crushers are a type of compression crusher that produce the most coarse material. This is because they crush rock with the natural lines of weak points. Jaw crushers make a great primary crusher to prepare rock for subsequent stages of processing.
Cone and gyratory crushers. They are also compression machines which crush materials between a moving and stationary piece made of steel. The output can be controlled through the position between the two pieces.
The chamber is circular however the steel moving part is not designed to rotate. Instead the wedge is employed to press down one side of the chamber while openings for discharges are created on the other. Cone crushers can be utilized in secondary and tertiary crushing but they should have a low proportion of fines.
Impact crushers. Impact crushers utilize mass and velocity to decrease the amount of feed material. The first process is to decrease the material that feeds the crusher using the rotating blow bars and hammers within the rotor. Secondary breakage occurs when the material is moved into the stationary aprons or the breaker plates.
Impact crushers tend to be utilized when shape is an important requirement and the feed material is not extremely hard and abrasive. Impact crushers crush rock according to natural cleavage lines, which results in higher quality products and form.
Final thoughts
It is important to fully be aware of the demands of each stage prior to deciding the right crusher for your needs.
In the primary stage, you must make sure that the material is to a size that your conveyors are able to handle.
Certain operations require further crushing during secondary and third crushing stages. These stages allow for more control over the amount and shape of the final product.
Understanding how to best match the type of crusher with the correct stage will ensure that it is efficient throughout your operation and overall profitability.
