Forming Chamber for the REX Process (Stone Wool)

The forming chamber ensures uniform deposition of fibers coming from the fiberizing machine and creates an evenly distributed primary stone wool mat in mineral wool production lines. Fibers fall onto a lamella conveyor that enables efficient extraction of process air, primary moisture removal and stable airflow conditions required for uniform mat formation.

The forming chamber is equipped with a skimmer and side rollers, which are water-cooled to remove granules from the fiberized material.

The side walls can also be water-cooled, forming a fine condensate layer on their inner surface. This reduces fiber adhesion to the chamber walls and helps shape the edges of the primary mat.

The chamber is designed as a robust and easily serviceable unit and may be equipped with scraping and washing systems as well as additional auxiliary and peripheral equipment. Each chamber design is adapted to the line capacity, operating speed and the type of mineral wool being produced.

The forming chamber can be supplied in classic triangular design or in a drum-type configuration.

Main advantages

• option of classic (triangular) or drum design

• stable and evenly distributed primary wool mat

• water-cooled side walls, side rollers and skimmer preventing fiber adhesion

• stainless steel construction available for applications using “green” binders

Forming Chamber for the TEL Process (Glass Wool)

The forming chamber for glass wool production ensures controlled and uniform deposition of fibers coming from the fiberizing section with binder already evenly applied. Fibers are deposited between two vertical belt conveyors that mechanically define the width of the primary mat.

The thickness of the primary mat is controlled by the speed of the lamella conveyor onto which the fibers are deposited. Correctly adjusted airflow and air extraction stabilize the fiber trajectory during deposition and prevent fibers from escaping outside the chamber.

The chamber is equipped with an air extraction system creating controlled airflow throughout the working area. Extracted air is subsequently filtered using a dry cyclone or wet separation system, depending on the customer specification.

The chamber construction allows easy access for cleaning and maintenance of all key components

Main advantages

• optimised air flow promoting even fibre deposition on the conveyor

• effective sealing of the forming zone minimizing fiber leakage

• easy maintenance and good accessibility of service areas

• stainless steel construction available for applications using “green” binders
