Description

Technical Field

[0002] Calcium carbonate powder is an important inorganic compound, usually in the form of white powder. The whiteness of the color varies depending on the raw materials and production process. The particle size can be produced and controlled according to different application requirements, ranging from a few microns to tens of microns. At room temperature and pressure, calcium carbonate powder has good chemical stability, but under high temperature or strong acid or alkali conditions, it will decompose or chemically react. Calcium carbonate powder modification is to treat the surface of calcium carbonate by physical or chemical methods to improve its performance and application range. Calcium carbonate is treated with inorganic surface modifiers to produce a double electrostatic layer on the surface of calcium carbonate, reducing the mutual repulsion between particles and reducing accumulation. At the same time, it increases its hydrophilicity and improves its wettability and dispersibility in water.

The stirring shaft can be driven to rotate by the motor 1, and the stirring frame can be driven to rotate by the stirring shaft. The raw materials can be stirred by the rotation of the stirring frame. The discharge roller can be driven to rotate by the motor 2, and the feeding is made more uniform by the discharge trough on the discharge roller.
