   Gypsum Wood Fiber Board Workshop
The innovative investment project providing for serial production of gypsum wood fiber boards, developed at Décor-1 PGW LLC in 2006, received the support from the Nizhniy Novgorod regional government and was given a priority status. Implementation of the project began in 2007 with the construction of the shop’s modular building, access roads and docking area, the purchasing and installation of modern German equipment supplied by Binos. The components used in the production are gypsum and barked timber. Incoming round timber is processed in a chipping machine. After an intermediate storage in a hopper, chips via a vibrating chute are sent to Hombak shredder equipped with cutting edges, where they are shredded to highly-flexible flat chips. Sifting through a separator helps remove coarse fraction which is additionally shredded in a Pallmann PSKM mill. Uniform moisture content is ensured when chips go through a rotary tube drier, where their moisture is brought to 80%. Mixing of components is done in a special mixer. All materials to be mixed are batched by weight. Depending on the timber moisture content, the amount of water to be added to the chips is determined automatically. Given the speed of the process and special properties of the raw material, a small quantity of chemicals is added to the water to control the speed of calcined gypsum hydration.
The mix formulation requires a finished board to contain approximately: Boards are formed by spreading the mix on transfer pallets, put together to make an endless belt. The filler unit is equipped with 4 continuously operating filling nozzles. fter the molding machine, the endless carpet of material on the pallets is broken to individual boards by a special quick-transfer conveyor and sent to the loading machine. Where an embossed board is required, a corresponding embossed mold is used.. A specially-designed control device ensures that only boards meeting the specified quality requirements are sent to the press. After pressing, the pallets with the carpet are stacked into a pile. The pile is placed into a press and fixed in a special clamping frame. To set, the piles, still fixed in the clamping frame, are sent to the curing area. In 2-3 hours, the piles are ready for breaking down. After that, the boards go to a drying tunnel. The pallets are cleaned, coated with emulsion spacer fluid and returned to the pressing area. Where embossed molds are used, they are removed from the pile separately and, after proper cleaning, returned to the molding area. Before the boards are released for delivery, their moisture content has to be reduced to atmospheric moisture. Drying is done in a special tunnel. After drying, individual boards go into a trimming machine which removes all irregularities from the edges. A stacker, installed downstream, forms a bundle which is by fork-lifts delivered to the finished product warehouse, to polishing or dimension cutting areas. The shop is scheduled for commissioning in march 2010. To stimulate market demand for gypsum fiber boards, the Company is planning to organize the production of veneered and laminated boards. |
