A Game of Efficiency: Open and Closed Circuit Crushing
In the world of crushing, efficiency is king. From the second material is fed into a hopper until it is screened, crushed, and conveyed to a stockpile, every moment matters. For this reason, it is critical to layout your portable plant and crushing equipment in a way that maximizes output while minimizing redundant processing.
No matter the industry, be it aggregate production, construction and demolition recycling, or asphalt, there are generally two types of crushing equipment layouts that are installed for the job: an open circuit layout and a closed circuit layout.
An open circuit crushing operation is distinguished by its multi-stage layout of screening and crushing equipment. Material flows through these plants without ever being returned back for additional processing.
In a closed circuit crushing operation, material can be crushed by equipment like an impact crusher or jaw crusher and then returned back to that same crusher for further reduction, if necessary.
The employment of either of these two types of crushing layouts can depend on different variables, including the composition of the material being processed, the amount of space available on a job site, or even the funds allotted for acquiring crushing equipment.
As open circuit layouts often require numerous machines for processing material, it can sometimes require more of an investment to obtain equipment and a larger amount of space to install it on the job. However, as open circuit layouts rarely return material for additional processing, they can be valuable in achieving maximum efficiency.
On the other hand, closed circuit layouts, like most portable crushing plants, are an affordable alternative and comparatively compact. Additionally, for certain types of abrasive material, it can be useful to utilize a return-feed system in order to effectively reduce the material being processed.
