Public Joint-Stock Company "Scientific - Research Institute of Glassplastics and Fiber" offers the Best in the World, latest developments in the field of equipment and fiber production technology of continuous basalt fiber (hereinafter - CBF)
We offer all forms of cooperation - from the drafting of the Feasibility Study Investments to "turn-key" lanch of the Plant and training customer's personal.

CBF production is based on the using of the latest achievements of scientific and technical progress. All the equipment is made in accordance with the requirements of today's market, safety and environmental friendliness.
Novelty and indisputable advantages of the new technology are in full using specificity and capabilities of molten basalt rock physics to reduce the cost of production. Our solutions enable, while maintaining quality, significantly reduce the cost of finished products, to increase the productivity of the equipment that gives to manufacturers a compelling advantage in the inorganic fibers market. 

Name of product provided to the production:

Roving Basalt fiber NBR 15 - 200H20 on packages (with the application of a lubricant). TU U 023.001-2001
Basalt textile thread.
Cuts of basalt fiber NBS 15 - 200 TU U 023,001 - 2001
Chopped Basalt fiber.

The production technology is  developed and property of PJSC "Scientific-Research Institute of Glassplastics and Fiber"

The raw material comes from a warehouse in the form of basalt aggregate, grain size 5 - 15 mm. The input control of raw materials is carried out according to specifications, by two indicators: the size fraction and debris. Raw material is supplied ready for processing form (washed and elapsed magnetic separation).
Raw material is loaded into the mobile hopper capacity of 0.5 m3, driven by an electric hoist. From the hopper the raw material is fed into the furnace charging device designed by Institute.

Melting is carried out in basalt melting furnaces. All of them are equipped with certified gas burners NB 10.11. The furnace design included a heat exchanger for cooling the exhaust gases and heating the air, supplied to the combustion. The combustion air supply by means of high pressure fans (1 operating, 1 reserve for 5 furnaces). Above the heat exchanger is an umbrella, through which the flue gas suction. In order to reduce the flue gas temperature at the discharge pipes installed additional heat exchangers for heating the air for drying of fiber and household water heating.

Production of filaments providing through a platinum-rhodium bushings at a melt temperature, providing a viscosity at which the melt flows from the bushings and produces a continuous strand.
The filaments are collected in a bunch on the roller lubricant and serves to lock the shaft winding machine.
After winding the yarn to a certain mass reel spool is changing automatically.

Drying multifilament yarn is carried out to a residual moisture content, not more than 3%. The Drying Chamber, developed by our specialists, uses the air after the heat exchanger in the path of exhaust gases from furnaces. Air movement is carried out fan, the included drying unit.
Discharged from the dryer thread on racks transported to the rewinding site. Hank multifilament yarn mounted on creel doubling machine and rewound in the roving with the specified characteristics. Finished packages are mounted on pallets and used in accordance with a further appointment.

Process manufacturing equipment:

The basis of the production of CBF are furnace, developed by our specialists.
Features of a furnace:

• capacity: 8 kg of dry fiber per hour

• installed electriccapacity - 14 kw-h

• natural gas consumption - 8 m3 / h

• recycling  water - 2 m3 / h

Other technological equipment:

• Winding Equipment for winding the primary fiber.
