ABSTRACT

In this paper, we will calculate the load content in the process of rotary kilns, the thermal quantity of the content of calcine components in rotary kilns during the frying process, electricity consumption – melting of calcine on electric furnace I, for ton calcine of ferronickel in Drenas.

The nickel ore is frying in a rotary kiln where a partial reduction of iron-nickel is achieved.

Fuels used as an energy source in the process of rotary kilns:

  • Kosovo lignite,
  • Coal from Indonesia,
  • Coal from Russia,
  • Coal from Montenegro
  • Fuel oil and pet-coke

During the industrial research at the Ferronikeli Plant in Drenas, we have ascertained that the maximum calcine temperature at the outlet of the rotary kilns is 700 ° C, during the analysis of the work.

Insufficient processing of iron-nickel ore for rotary kilns causes major problems in not reaching the temperatures inside the kilns, where the high humidity of iron-nickel ore causes great difficulties in the process of frying in rotary kilns.

Because of not achieving high temperatures in rotary kilns, the preparation of the calcine for electric furnace does not reach the proper preparation.

The amount of calcine during 2016 that entered the electric furnace was 291919.64 tons, the amount of energy consumed for melting calcine in electric furnace, reached 553.42kWh / t calcine, while the amount of electricity consumed was 57.92 MWh /t Ni.

Keys words: Calcine rotary kiln, plant, lignite etc.
