The efficiency of crushing based on polymers processed are 90% for HDPE, 68% for LDPE, 45% for PVC and 10% for PET bottles. The developed crusher can be used to reduce the volume of plastic waste ...
Since the crushing plants operate under harsh conditions and involve very abrasive material, multiple factors can influence their performance. This paper assesses a number of factors affecting the performance of the crushing plant by addressing the critical design parameters and consideration of ore characteristics, operability and maintainability.
opening of 22" by 30", a 46 x 46 jaw crusher has a opening of 46" square. Generally primary jaw crushers have the square opening design, and secondary jaw crushers have rectangular opening design. Jaw crushers are used as primary crushers in a mine or ore processing plant or the first step in the process of reducing rock.
