Crushing is a dry operation which only involves dust control using water spray (Drzymala, 2007). A primary or jaw crusher is located at the mine site and reduces the particle diameter of the ores into <6 in. The crushed ore is then transported to the mill site for crushing, grinding, classification and concentration.

1. Introduction. The main challenge for rare earth element (REE) extraction from primary deposits is the low concentration of REE-bearing minerals present in a variety of gangue minerals, including silicates, carbonates, fluorites, and/or phosphates (Vijayan et al., 1989).Among the residues generated during the pre-concentration of rare earth minerals from certain …

The capacity of PF impact crusher is 30-800 t/h. The biggest capacity machine is PF1820, its capacity is 600-800 t/h.
If the crushing plant will be operated remotely and be as highly automated as possible, the debris can cause unpredictable clogging of the grizzly. Getting someone to the plant to clean things can take a while, and the cleaning itself takes time. Downtime leads to lower long term capacity and weaker process reliability.
