Rock wool system is used for slitting the big block rock wool into branches and conveying & turning to change the direction of fiber, thus make the rock wool blocks to meet the requirements of construction composite panels’ intensity, and then arraying, milling edge, spraying glue on up & down panels and at last cohere with the up & down steel panels. The system includes storing elevator, slitting machine, lengthways conveying, 90 degrees turning over, arraying device, joint edge milling, glue-spraying system, auto stacker for wooden pallet, dust suction machine and so on. Rock wool glue system has two types: one is two components of ISO and polyhydric alcohols; the other type is three components of ISO, polyhydric alcohols and catalyst. 

1)Machine speed 1:6m/min (50mm thickness*2400 length)
2)Machine speed 2:4.5m/min (50mm thickness*1800 length)
3)Glue spary weight: 180g-250g
4)The height of final composite panel:50mm,75mm,100mm,125mm,150mm,175mm,200mm
5)The max efficient width of final composite panel:1000mm
6)Rockwool strips: max 10 strips
7)The max height of the raw block rockwool: ≤105mm
8)The height tolerance of the raw block rockwool: ：±2mm
9)Raw block rockwool standard: national standard
10)Raw glasswool standard: national standard
11)Rockwool weight: 80~120kg/m³
12)Glasswool weight: 64~100 kg/m³
13)Cutting blade seam width: 3.3mm
14)The length of the rockwool strip: 1.8m~2.4m
15)The tensile strength of rockwool: ≥7.5Kpa
16)The compressive strength of rockwool: ≥40Kpa
17)Hydrophobic of rockwool: ≥98%
18)Shot content of rockwool: ≤10%   Grain size＞0.25mm
19)The distance from glue spray point to double belt conveyor entrance: 7m
