PLANT FOR MANUFACTURE THIN BASALT FIBRE

Plant consists of the bathing melting furnace of direct heating with the automatic or manual loader, unit of formation of melt jets and the takeup-forming conveyor. If necessary plant can be completed with broaching machine or a line of reception of soft slabs with synthetic binding.

Basalt thin staple fiber (BTSF) is made by one-stage blowing of the fused basalt jets by the condensed air, that essentially deflates their cost price in comparison with BSTF.

The electric equipment and automatics provide the control of an operating mode of the furnace, automatic loading of a crumb, the control and management of operating modes of feeders, and also the alarm system.

Manufacture of a basalt thin fibre consists in the following: by means of batcher the raw material moves to a zone of loading of the furnace. Loading is made automatically.

The furnace a bathroom, melting, direct heating, continuous action. The furnace is supplied by a radiating recuperator for heating air going on burning. For heating the furnace and a feeder are used the flat flaming gas-jet established in the arch of the furnace.

The basalt rubble loaded into pool of a melting part of the furnace melts at temperature of gas space 1450 20 . The melt go in a feeder in which ground part it is established a bushing assembly warmed by an alternating current. Under action of hydrostatic pressure of a melt column in a warmed-up feeder continuous jets of melt which get in blowhead are formed. Condensed air, passing through blowhead, inflates and extends a malt jets in the form of staple fibres.

Further fibres go through diffuser to the faber precipitation chamber and then are precipitated in the form of a carpet on a horizontal moving grid of the takeup-forming conveyor. The fibrous carpet further is rolling and packed, or acts for the further processing.
