(b) Are you producing chemical activated products? If yes, phosphoric or Zinc chloride or both?
Presently our pilot plants in operation making use of Phosphoric and Zinc Chloride for activation will be commercialized in 2016.
(c) Are you using rotary or vertical kilns?
(d) How many kilns?
12 Rotary Kilns
(e) Production capacity per kiln?
800 kgs per day

(g) Are you able to water or acid wash the product for removing impurities?
90% of our production is acid washed and the balance is water washed.
(h) What kind of crushers are you using and the resulting particle sizes?
We use Impact Pulverizes as most of our carbon is 200 mesh powder
(i) What is the percentage production of Granular and powder types?
