Mixing, preserving, weighing raw material for glass wool production line
The glass wool is obtained by melting and transferring combinations of materials such as silica sand.
In the first stage of the process the material is weighed and blended.
Storage devices are dedicated to batch and blending raw materials.
When the mixture is complete, the mixture is collected in a silo that supplies the feed to the melting furnace.


 
Melting furnace for glass wool production line
The melting furnace for the wool production line uses electrical energy to melt the material trasforming it into the molten glass.
Feeding systems hold a uniform layer of non-fused material on the entire surface of the "molten bath tube" so that the excess of the melted system remains cold (cold head).
Liquid glass is then sent through a special feeder feed channel to various fiber systems.


Air-cooled head - Melting furnace
The "cold head" electric refrigerators have the following individual advantages that are extremely suited to the needs of the growing market:
energy efficiency,
Low emission: The filter system consists of only one filter bag
easy to use for operators: control of all functions, power settings, glass level control and load control are automatic, operator intervention is reduced to a minimum; : compared to conventional heaters (gas furnace) this furnace can be turned off or placed in the waiting state very quickly, according to production needs, not to damage the refractory material, low maintenance costs.
The heater has a minimum capacity of 10 tonnes per day and a maximum capacity of 55 tonnes per day in fiberglass production.
For higher capacity, it is possible to install multiple kilns in parallel, which can feed only.
 
Fiberizer, spinning machine for woolen glass production line
The fiber is installed under the feeder.
Melted glass, quantified through special holes (bushings), is electrically heated and cooled, to basic chemical fibers including high speed rotary perforated discs and heated by heat. .
Due to the centrifugal force, the glass is pushed through perforated holes (using compressed air and gas of special tapes at high pressure) and converted to fiber.
The scavenging parameters (combustion chamber temperature, flame pressure, air / gas ratio, air and gas velocity) are controlled by the control system to determine the fiber diameter and the length of the muscle. Department of demand.
Typically, to achieve the required power of the line, several fibers are used in parallel.
The size and capacity of each fiber depends on the diameter of the perforated disk. Capacity can vary from 300 to 950 kg / h fiber for each machine.

 
Forming chamber for the production line of glass production line
The chambers form a part of the plant, where the glass wool fibers produced on the fiberizer are collected.
This machine includes perforated horizontal conveyors (from which a large amount of air is drawn). Two symmetrical conveyors along the vertical make up the two sides of the chamber.
Two conveyors continue to form two walls of the chamber (front and rear).
These conveyors are continuously cleaned and washed.
At the output of the forming chamber, the sensor can be sent to the main line or to an auxiliary unit that is collected without maintenance.
Non-processed lace is used to produce special products (pipe segments, shapes, etc.).

 
Crimping machine, yarn-oriented unit for wool glass production line
Gamma Meccanica SpA has developed a special press for glass wool that improves the mechanical properties of the product, directly affecting the fiber orientation.
This system is made on the basis of requirements and cooperation with a number of important glass manufacturers. The crimping machines for glass wool have the ability to vertically orient wool fibers to get the product (generally panel) with high compressive strength and layered strength (even with low density products). .


 
Furnace for glass wool production line
The purpose of the oven is to coalesce adhesives (such as different plastics) previously mixed with fibers in the blurring area; Further, during the maintenance process it senses its final thickness.
The maintenance process is carried out using hot air.
Baking ovens include various parts connected together; Each unit is autonomous and has its own hot gas circulation system.
Hot air in the oven is made up of special gas burners operated by natural gas, GPL, or gasoline.
The machine consists of two opposite conveyors (top and bottom), scratch-resistant and formed by high-resistance conductors and perforated steel flights.
The bottom conveyor belt is fixed and the top one is adjustable in height, this allows us to get the required product thickness.
All settings (speed, thickness, temperature, lubrication, cleaning, etc.) are managed automatically.
Gamma Meccanica ovens can ensure optimum results for dimensional tolerances, product maintenance, product surface quality and low energy costs.

 
Cutting unit for wool glass production line
Cutting units are placed behind the kiln.
At the output of the kiln occurs trimming material: the edge edges are automatically restored and returned to the production process.
Then cut vertically and cut horizontally, based on the final size required.
At this stage of production, the product assumes the final geometry is required.
Specifically, Gamma Meccanica offers the following cutting systems: edge trim systems with band saws without band saws, vertical slitting units with 2 to 6 blades with no dust to determine Product width high speed chopper to determine the product length
The main features of the cutting equipment proposed by Gamma Meccanica SpA are high accuracy, minimal tolerance, and no dust cutting.

 
Heat coil for glass production line (Direct parts for insulating material)
The heated rollers are used to couple the glass wool with the material (can use aluminum, kraft paper and glass cover). Facing materials are used as fence for vapors and dust.
The heated rollers are installed at the cold end of the line (at the outlet of the furnace and after the trim unit is trimmed).
The process of bonding to an electro-magnetic roller melts the plastic film (when the facing material has a pre-plastic film) or at a lower temperature but with the addition of vinyl or similar glue on the water.
Faces can be made only at the bottom of the product or on both sides: the system works at high speed, complete with a dedicated machine to facilitate operator functions including changing coils with reinforcement material.

 
Drawer for glass wool production line
The unloading unit is the production unit installed at the cold end of the line after the cutting system, which is stacked onto the glass wool prep to be packaged.
Queue starts from the bottom (one layer is inserted under the other) with special equipment.
The number of layers and height of the stack can be adjusted from the control system.
To achieve the highest production rate, the unloader can be completed with a front loader.
Main features of the loading and unloading machine
Main features of the Gamma Meccanica stacker:
High performance (stacking speed and package height)
high degree of automation;
Low maintenance;
Machine installed in the line, the product can go through the unit when not required to stack operation (for example with coil feel).
Easy to use and control
Arrange different widths and lengths without any intervention for adjustment or setup

 
Winding machine for glass wool production line
A roll up unit automatically rolls onto a mattress or felt.
The roll up machine can be equipped with a precompression system that compresses up to a required value before the phase of rolling starts.
The "wrapping" machine winds automatically rolls from the outside with a plastic film or paper. Therefore, rolls are being sealed, preventing deployment.
A special heating system rolls it close at the top. Depending on the type of plastic film, the cover may be either partially or completely.
The operator can choose the compression ratio that suits the type of production. Special software ensures perfect uniformity, compression and circulation of rolls.
The use of production code ensures that the machine can be quickly set up to change production fast.

 
The system to recover the production waste and the edge of the glass wool production line
The waste recovery system produced by Gamma Meccanica SpA is designed to improve the overall efficiency of the product line (economic advantage), recovery and recycling of yarn waste.
In general, the system for the recovery of waste products provides:
The ability to send edges created during pruning and grinding directly into the chamber creates or replaces a silo.
Recoverable waste production, defective sheets or large wool from the main line with an independent unit processing the material converts it into pieces and sends it through the cylinder to the same dump.
The ability to dosage by the extractor, dosage, accurate quantification of the amount of waste produced into the product, optimize the mixing and avoid products of poor quality and low mechanical properties.
Important note: Fans of the cyclons to transport waste are not crossed by the product and do not come in contact with the material. So wear is a significant limitation with the ability to use a regular and business fan.
 
Packing unit for glass wool production line
Packaging units are the final step of the production process.
Gamma Meccanica SpA recommends different packaging systems to meet the needs of our customers.
The packages are wrapped with polyethylene and thermoshrinked as they come out from the stacker.
In packaging the packaging, depending on the density, can be compressed, reducing its volume, thus reducing the shipping cost.
Once wrapped, they can be stacked automatically on the pallet by a human robot.
Packaging can also be completed using a zinc-plating machine or a tensile film packaging machine.
