Limestone Dryer Introduction
The Limestone Rotary Dryer is specially designed for drying limestone, lime powder, calcium carbonate, and other non-adhesive mineral materials. It adopts a rotating drum structure with high-temperature hot air as the drying medium, achieving fast and uniform drying with excellent thermal efficiency.
1. High Drying Efficiency - Hot air fully contacts with materials for quick moisture evaporation
2. Robust Structure - Wear-resistant drum body ensures long service life
3. Energy-Saving Design - Efficient burner and thermal insulation reduce energy consumption
4. Customizable - Drum diameter, length, motor power, and heat source can be tailored
5. Stable Operation - Smooth rotation, automatic temperature control, low noise
Applicable Materials
` Crushed limestone
` Limestone powder
` Calcium carbonate
` Quicklime
` Mineral slag
` Gypsum, clay, and similar non-sticky materials
The limestone enters the rotary drum through the feeding chute. As the drum rotates, internal lifters lift and scatter the material, allowing hot air to penetrate and remove moisture. The dried product is discharged at the outlet, while exhaust gas is collected via a dust removal system.
