Two Closed Circuit Crushing Process

Open or Closed Circuit Crushing

Assume, for example, that we are to crush a material, in a closed-circuit crushing stage, to pass a 3/4″ square opening (as determined by a flat testing sieve); that our screen, which forms a part of the circuit, will be fitted with the proper size of openings to make this 3/4″ product, and will be capable of performing at 90% efficiency.

A Game of Efficiency: Open and Closed Circuit Crushing

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.
