[0002] Rock wool board, also known as rock wool insulation decorative board, is an inorganic fiber board made of basalt as the main raw material and processed by high-temperature melting. Rock wool insulation board is light in weight and has a low thermal conductivity, absorbs heat, and is not easy to burn. It is often used in steel structure workshops, roofs, walls of simple mobile houses, ceilings and partitions of clean air rooms, etc. Rock wool insulation board needs to be dried in the production process.

[0003] A drying device for producing rock wool insulation board with the announcement number CN 112833649 A was retrieved, which includes a frame, a drying box, and a conveying part.

The drying box is arranged vertically, and a drying mechanism and a guide mechanism are arranged in the drying box. The drying mechanism is arranged on both sides of the conveying part. The guide mechanism includes a vertically arranged guide roller and a rotating shaft. The rotating shaft is symmetrically arranged on both sides of the conveying part, and the guide roller is rotatably connected with the rotating shaft. The rock wool insulation board enters the drying box in a vertical state, which avoids the situation that the surface of the rock wool insulation board in contact with the conveyor belt is difficult to be directly affected by the drying mechanism when the rock wool insulation board is laid flat, resulting in incomplete drying and residual moisture, thereby improving the drying efficiency.
