FIELD: chemistry.
SUBSTANCE: system includes separate primary treatment systems of the carbonaceous reductant, phosphoric ore and quartz ore. These systems by means of the transport means are equally connected to the mixing machine of pellets. The primary treatment systems for the carbonaceous reductant and quartz ore are separately connected to the mixing machine of the outer shells by the transport means. All primary treatment systems consist mainly of a series-connected single-stage crusher, an intermediate hopper, a grinding machine, a storage and a dispenser. Further in the process, first, the carbonaceous reductant, phosphoric ore and quartz ore separately are primary treated, then transported to the mixing machine to create pellets, after the primary treatment, the carbonaceous reductant and quartz ore are separately sent to the mixing machine of the outer shell for mixing.
EFFECT: decreasing the cost price and reducting the consumption of raw materials during production.
