Gypsum Crushing and Grinding Process

Gypsum is a widely used material in the fields of construction, medicine, papermaking, and more. The grinding of gypsum is an important step in its preparation process. This article will introduce the process of grinding gypsum powder.

Raw Material Preparation

The main raw material for gypsum is natural gypsum ore, which contains mainly low-hardness phosphates. In the gypsum powder grinding process, it is necessary to crush, screen, and wash the natural gypsum ore to ensure the quality and fineness of the gypsum powder.

Crushing

After the raw material preparation, the gypsum ore is sent to a crusher for coarse crushing. The selection and setting of the crusher should be adjusted according to the characteristics of the raw materials, such as hardness and viscosity, to achieve better crushing effect.

Screening

The crushed gypsum block needs to be graded by screening equipment to obtain gypsum powder that meets the requirements. In the screening process, attention should be paid to controlling the screening speed and amplitude to avoid the production of too many fine particles, which may affect the quality of gypsum.

Grinding

The screened gypsum block needs to be ground to obtain gypsum powder. The selection and setting of grinding equipment should be adjusted according to the hardness and fineness requirements of gypsum. In the grinding process, attention should be paid to controlling the speed and pressure of the grinding equipment to obtain gypsum powder that meets the requirements.

Powder Grading

The ground gypsum powder needs to be graded to obtain particles of suitable size. In the powder grading process, attention should be paid to controlling the speed and amplitude of the grading equipment to obtain better grading effect.

Packaging

After the powder grading process, the gypsum powder needs to be packaged for transportation and use. In the packaging process, attention should be paid to selecting suitable packaging materials and containers to ensure the quality and safety of the gypsum powder.

Gypsum powder grinding is an important process in the preparation of gypsum. The preparation process needs to go through multiple steps, such as raw material preparation, crushing, screening, grinding, powder grading, and packaging. In each step, attention should be paid to selecting suitable equipment and setting reasonable process parameters to obtain gypsum powder that meets the requirements.
