The mechanical classi-forming machine consists of two surface forming station and one core forming station. The mat is formed in classification structure in the mechanical forming machine. The two surface forming station is installed at the two ends of the flakers flow with one at the flow beginning to form bottom face layer and the other one at the flow end to form upper face layer. The glued surface flakers are distributed to the two belt conveyors and then come to the surface forming bin via the swing feeding screw conveyor. The core forming station is located in between the two surface forming station. The glued core flakers go to the core forming bin via swing feeding screw conveyor. The mat with classification structure is formed after the flakers flow goes through the mechanical classi-forming machine.
The function of three-pass dryer is to achieve required moisture content of dried flakers. The flue gas coming out from the combustion chamber flows to the mixing chamber where the flue gas is mixed with fresh air by proportion to reach certain temperature required by the process control. The flue gas, after going through the multi-cyclone filter, is blew into the core of the drying drum. The flakers are mixed with the flue gas to achieve heat transfer and the moisture of the flakers are evaporated during the flow of flakers. The flakers are floating through the three passing chamber and leave the drying drum with required certain moisture content. The dry flakers are dropped to the downstream process by the rotary discharger under the main cyclone. The exhaust, after going through the multi-cyclone, is partly going to the air via chimney, and partly recycled to the mixing chamber before the dryer feeding. The heat efficiency is improved with the recycling of the exhaust partly.
The rotor dryer is to achieve dry flakers with certain moisture content decided by process control. The design of the themal oil tube inside the dryer has a feature of quick heat transfer and uniform heating. It is suitbale for different types of flakers. The rotor dryer has efficient heat transfer performance due to the design of radiation and convertion combined functioning of thermal oil. It is easy for installation. The low temperature reduces the chance of catching fire.
The function of hot press is pressing the mat after pre-press to master board under regulation of pressure and temperature.
