Services: Development and supply of pulverised fuel preparation plants together with a dual-fuel burner
Drying technologies,
Granulation, roasting of industrial materials and many others
can be based on the combustion of any fossil fuel (natural gas, liquid fuel, fuel coal dust, fine wood fuel).

Fuel costs determine the economics of enterprises and amount to
15-17% of the cost of hot asphalt.
20-30% of the cost of mineral processing products,
The cost of the processing of mineral products, e.g. non-ferrous metal concentrates, iron ore concentrate.
30-40% cost of cement, lime, various intermediate products produced by sintering,
for example keramzite, iron ore pellets.
The cost of fuel fully determines the cost of hot water and heat production and the economics of the housing and utilities sector, especially in the eastern, northern and north-eastern regions, with seasonal fuel deliveries.
Technological processes and coal dust
Numerous technological processes can be carried out using pulverised coal or wood fuel:
drying of: copper, zinc, pyrite, molybdenum, fluorite, titanium,
barite, nickel, iron ore and other concentrates, industrial salts, bentonite clays, sand and other materials;
Drying of flammable materials, such as coal, in an oxygen-depleted environment;
drying and granulating suspensions in spray dryers;
production of cement, lime, expanded clay, alumina sintering roasting of iron ore pellets,
brick burning;
granulation of mineral fertilisers and other processes;

Methods for the preparation of unmilled coal dust related to coal production and beneficiation technology
.
are used in coal preparation plants, to improve the efficiency of the plant, increase the quantity,
quality and value of marketable coal products:
А. Drying of fine coal concentrates of 1-13 mm and coal slimes of 0-2 mm for coal preparation leads to obtaining dry coal dust with particle size of 70-100 microns accumulated in the hoppers of bag filters during dry-cleaning flue gases from coal drying equipment.

Б. Thermal-aerodynamic separation . Thermal-aerodynamic separation of lumpy coal to separate the dust component is used in coal preparation plants, ports or coal trans-shipment points. The separators improve the quality of lumpy coal, the pulverized coal fraction is dried and separated from the coal and can be used for own needs, or sold to other companies.

Marketable coal quality improvement
Thermal-aerodynamic separation . Also used in large thermal coal-fired power plants to optimise pulverisation processes, The thermal wind separator is also used in large thermal power plants to optimise the coal dust preparation process.
Methods of producing pulverised coal without milling reduce the cost of pulverised coal to the cost of lumpy coal. The equipment is described in brochures.
