The invention discloses a raw material cooling and ball milling integrated system of a gypsum board production line. The raw material cooling and ball milling integrated system comprises a PLC master controller and a ball mill. A feeding reamer is arranged on a feeding port of the ball mill, and a discharging port of the ball mill is provided with a dust collector and a discharging chute. A hollow interlayer is arranged on the outer wall of the feeding reamer in the length direction of the feeding reamer, the inner wall of the hollow interlayer serves as the outer wall of the feeding reamer, the end, close to the outer end of the feeding reamer, of the hollow interlayer is provided with a wet gas inlet and provided with a flow control valve, and the other end of the hollow interlayer extends into a bin of the ball mill and supplies wet gas into the bin. The flow of the wet gas entering the bin is controlled by the flow control valve to account for 3%-5% of the total amount of production materials in the bin. Temperature sensors used for controlling the feeding temperature and the discharging temperature are arranged on the outer wall of the hollow interlayer and the outer wall of the discharging chute correspondingly, and the temperature sensors upload the detected feeding temperature and discharging temperature to the PLC master controller. The dust collector has heat preservation and adjustment functions, and the environment temperature in the dust collector is the fixed value.
Description
technical field [0001] The invention belongs to the field of gypsum board production equipment, and in particular relates to an integrated system for cooling and ball-milling raw materials in a gypsum board production line. Background technique [0002] Limestone-gypsum wet flue gas desulfurization is currently the most effective method for large-scale removal of sulfur dioxide from flue gas in thermal power plants. As a by-product, desulfurization gypsum has attracted more and more attention. Desulfurized gypsum is used as a raw material to manufacture gypsum board technology, which has become an effective means of absorbing desulfurized gypsum. [0003] Compared with natural gypsum, the particle size of desulfurized gypsum is relatively uniform, and there is no large amount of fine powder. Its distribution band is very narrow, and the particles are mainly concentrated between 40 and 60 μm. The gradation is far worse than that of natural gypsum after grinding. pink. Calci...
