Mineral powder granulation

Raw material preparation: Firstly, the mineral powder needs to undergo appropriate raw material preparation. This may involve steps such as screening, grinding, mixing, or proportioning to ensure the quality and composition of the raw materials meet the requirements.

Wet granulation: Wet granulation is one of the common methods used in mineral powder granulation. In this process, the mineral powder is mixed with a certain proportion of water or other liquids and undergoes wet granulation through equipment such as stirring, spraying, or drumming. The mixture forms granules in the stirring or drumming process and is solidified into granules through drying or curing. Generally, rotary drum granulation production lines and disc granulation production lines are used.

Drying: After granulation, the granules usually need to undergo drying to enhance their stability and strength. This may involve steps such as drying, adding curing agents, or heat treatment to solidify or harden the granules.

Screening and packaging: Finally, the granulated mineral powder particles need to undergo screening to remove particles that do not meet the size requirements. They are then packaged and stored.
