Plant for production of the basalt super fine (thin) fiber is indicated for production of the staple basalt super fine (thin) fiber out of rock melts by the blowing method of the primary fibers by the high speed stream of gases brought to a great heat.

BSTV production plant is operated by one operator per shift. Working routine of the furnace is non-stop, use standard is 350 days a year. Every shift except the operators should have a technology equipment adjuster, including KIP & A, and a fitter-mechanic operator. Adjuster and mechanic operator operate several plants combined in one production section.

Service Life term of the plants before the refettling.
Replacement of draw plates of the heat resistant alloys should be produced in average one time per 20-22 days.
Replacement of quickly-worn out details and components is fulfilled without significant time and money expenditure.

Raw material for the BSTV production is the basalt crushed rock (with fraction size 3 - 15 mm)

Through the loading-dozer the crushed rock is fed to the melting furnace under temperature 1400 -1500°С

Furnace temperature is regulated by the amount of gas and air supply. Air is supplied through metal recuperator, where it's warmed due to the use of moving away gas warmth Melting by gravity through the filters stretches as a continuous yarn with diameter within 100 -250 mkm

Feeder is set to form continuous primary yarn out of the melting. The feeder consists of the heat resistant draw plate fixed between two fridges. For melting passing through feeder draw plates the latter is heated by electricity by transformer to the temperature 1300 -1320°С.

Those formed primary yarns by a special mechanism are stretched, formed and fed for blowing. The main working unit of stretching machine is the pair of rubber rollers that evenly distribute the primary fibers and head to the blowing burner nozzle. Rollers are moved by the alternating current engine with smoothly regulated speed of rollers' rotation. Roller rotation speed must provide fiber feeding to the nozzle and be within 5-6.5 revolutions/min.

The primary fibers get to high temperature and high speed gas flow under the pressure of which they melt and are blown into the staple super fine (thin) fiber. Blowing burner consists of lid, nozzle and water cooled frame fettled with refractory bricks. Fettled frame with a lid make up the combustion chamber. Combustion chamber is heated by the gas - air mixture from the heating system.

Flow of combustion products through the blowing burner nozzle streams perpendicularly to the supplied fibers.

Primary fibers stretch and are completely blown.

Fibers through the diffuser get in to reception - forming unit.

Diffuser consists in 2 metal cones connected with the overall drum production line at the corners. The main unit of the production unit is a net. Below the net the chamber of unloading is connected by the pipeline with ventilation system. Combustion products go away through the net to ventilators, and the fiber stays at sewer as a thin layer. The latter is winded on to the drum when it approaches. When the winded on the drum layer width is sufficient (about 100 -150mm) it is cut. This is the process of canvas production.

The term of production of the plant is 1-1.5 months.

Assembling, mounting and set-up works are 0,5-1,0 months.
