The foam rock wool composite board machine adopts the rolling plate making process. The production process of the whole board is completed at one time from the thermal insulation layer, cloth laying, main material loading, composite, and re pressing. The equipment has a good degree of automation, easy operation, and stable operation. It can produce various thermal insulation and energy saving products of different specifications and materials according to customer requirements. The product surface is smooth, flat, and dense, changing the cumbersome construction process of the expanded polystyrene board thin plastering external wall thermal insulation project, and improving the construction speed and economic benefits.
