Gypsum powder production and processing technology
The invention discloses a gypsum powder production and processing technology. The gypsum powder production and processing technology comprises the following steps: step 1, preparing raw materials: natural gypsum and chemical gypsum; step 2, coarse crushing: feeding the natural gypsum and the chemical gypsum into a crusher for coarse crushing; step 3, carrying out coarse crushing to reach the feeding particle size suitable for entering a trapezoidal pulverizer, and pulverizing the coarsely-crushed natural gypsum to the needed fineness by the trapezoidal pulverizer; step 4, calcining: feeding the ground gypsum raw powder into a boiling combustion furnace for calcining, and removing a part of crystal water; and step 5, feeding the calcined qualified gypsum powder into a finished product warehouse for later use. The method has the beneficial effects that the gypsum powder production and processing technology is simplified, the gypsum powder production and processing quality is improved, heat conduction oil and high-temperature hot air are adopted for heating at the same time, part of crystal water is conveniently removed, and the required gypsum powder physical index is achieved.
本发明公开了一种石膏粉生产加工工艺，所述加工工艺如下：步骤一：原料准备：天然石膏、化学石膏；步骤二：粗碎：将天然石膏、化学石膏送入破碎机粗碎；步骤三：粗碎至适合进入梯形磨粉机的进料粒度尺寸，粗碎后的天然石膏矿石经梯形磨粉机粉磨至所需的细度；步骤四：煅烧：粉磨后的石膏生粉送入沸腾燃烧炉进行煅烧，脱去一部分结晶水；步骤五：煅烧后的合格石膏粉送入成品库备用；本发明的有益效果是：简化了石膏粉的生产加工工艺，提高了石膏粉生产加工的质量，采取导热油和高温热风同时加热，便于脱去一部分结晶水，达到所需石膏粉物理指标。
