While reflective products like concrete have been the traditional material for outdoor noise barrier walls & enclosures, the advanced sound-absorptive materials found in Sound Fighter® Systems’ products present a much more effective abatement option. Products like concrete or brick simply bounce sound waves off their surface in different directions. Sound Fighter’s products actually absorb or completely eliminate the sound waves that hit them…significantly reducing overall noise.

General structure of equipment

De-coiler

Technical parameters

Width of material sheet: 600—1050mm； Thickness of material sheet: 1.5mm(alufer)/1.0mm(Galvanized sheet)

Inner diameter: φ508mm Range of expanding: ф480-520 mm

Maximum outer diameter: φ1200mm, loading: ≤6T

Motor power:7.5kw Frequency Motor

Speed:0-10m/min,adjustable

Leveler

Working rollers:13+2 Rollers

Feature of structure: after the quenching and tempering, chrome-plating processing, the rigidity, surface roughness of the roller etc. are all enhance greatly; It is composed by the clamping roller and the leveling roller, the clamping roller may the independent control, the leveler has one pair of horizontal guide roller and two pairs of vertical guider roller and easy to

adjust by hand wheel.

Between the leveler and the feeding device, there is optical sensor, sends out the feedback signal to

the control system, the control system sends out the instruction to the frequency conversion motor to

change speed to control the storage quantity of the sheet.Achieves the uninterrupted level goal.
