NewsFlash No:01-MA/01/15

PT. SSE-VAN DER HORST INDONESIA is pleased to announce that it has successfully manufactured for PT Indonesia Chemical Alumina (ICA), a subsidiary of Japanese company, the Jet Mill Rotors which  is a critical high wear & tear component of the milling equipment . 

PT ICA is currently  constructing a chemical grade alumina plant with a capacity of 300,000 MTonnes at Tayan city, West Kalimantan in the Republic of Indonesia (ICA Project) . The chemical grade alumina (CGA) will be exported to  Japan and the Asian market.

Van Der Horst is proud to have provided  local engineering expertise to support PT ICA thereby enabling it to be less dependent on imports

What Is A Jet Mill?

Jet Mill rotor is part of equipment to produce of Aluminum Oxide (Al2O3), or Alumina, who is one of the most versatile refractory ceramic oxides. Alumina can exist in several crystalline phases, with the alpha phase being the most common for engineering applications because of its high stiffness, strength, corrosion resistance, and very high temperature resistance. High purity Alumina is usable in oxidizing atmospheres at temperatures exceeding 1900°C. The exact material properties depend strongly on the percentage of Aluminum Oxide.
