Description

Technical Field

[0001] This utility model belongs to the field of drying technology, specifically relating to a drying device for mineral powder production. Background Technology

[0002] S95 slag powder is a high-grade slag powder that can improve the strength and durability of concrete, enhance workability, reduce heat of hydration, and promote volume stability. S95 slag powder contains over 30% active inorganic matter and is typically produced from water-quenched blast furnace slag through drying and grinding processes.

[0003] Mineral powder is usually dried using a drum dryer. The drying effect of the mineral powder is related to the length of the drum. The longer the drum, the better the drying effect. However, due to the limited size of the equipment, the existing drum dryers are not long. In order to improve the drying effect, the drying time is extended, which greatly reduces the drying efficiency of the mineral powder. In addition, the drying method of drum drying does not allow sufficient contact between the mineral powder and the hot air, which affects the drying effect of the mineral powder.
