DOUBLE BELT PRESSES

This new machine has been studied and optimized to produce highly dense boards from nonwoven, from any kind of non woven, waste material or particles. The press uses plain and solid belts, that are able to press the product very heavily and cool it while it is still under heavy pressure. The heating of the product is provided by hot plates that transmit the heat to the plain (solid) belts and also hot rolls. The heating time is given by the length of the belt + hot plates, with the heating of the plates and rolls made by forced thermal oil circulation.

These can be warmed up using a gas-fired unit as well as an electric power unit. Cooling of the felt is made by water cooled plates and rolls in contact with the belts, situated in the last part of the module.

Cold water flows into and through the cold plates and rolls, via a centrifugal pump. With the press , which is a combination of calender and oven, the material is ALWAYS under compression.

The belts are supported by the rolls and plates and the pressure is applied for their full length with belt distances adjustable from a central control board.

Applications: Compressing of polyester thermobonded webs, in blend with bico, to produce sound/thermal insulation boards and decorative felts ; Compressing of webs made with cellulose + Bico, used under wooden floors, to prevent noise and to insulate from cement floors; Compressing of needle punched felt made in Kenaf+PP in order to facilitate the 3d forming process in automotive industry ; Compressing of wood-fibers with BIco. This is used to produce medium density wood boards, without the use of an extremely expensive wood production line ; Lamination of two or more felts without any chemicals, just using the fibers; Laminating of shoddy felt with a polyethylene foil, to produce a protective felt for painting; Smoothing of thermobonded product removing marks from the oven belts

Equipping the machine with our powder\particles scattering unit, it is possible to transform any of your waste containing fusible fibers or fusible material into rigid boards that can then be used in various applications.
