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.

  • Iron and Aluminium Removal from Algerian Silica Sand by Acid

    This work refers to a process of purifiion of silica sand and, more particularly, to a process of iron and aluminium removal from the Algerian silica sand particles. Iron compounds are among the most difficult impurities to release from the sand particles. Several methods to remove iron from the sand particles are used;
