The evaluation by customer: Because of our high requirements for final particule granularity, I have followed the views of LIMING engineer with a two-stage crushing - a PE Jaw Crusher for primary crushing and two Hydraulic Cone Crusher HST160 for secondary crushing. Quite stable performance, also the production makes me satisfied. To my most pleasant surprise, the intelligent operation of machine has saved me a lot of time and also costs.

    All rare-earth ores contain less than 10 percent REO and must be upgraded to about 60 percent in order to be processed further. They are first ground to a powder and then separated from the other materials in the ore body by various standard processes that include magnetic and/or electrostatic separation and flotation.
