Limestone Dryer
Limestone Dryer Introduction
Limestone is a kind of precious mineral resources, its main component is calcium carbonate, which has good chemical resistance, acid resistance and corrosion resistance. Generally, the limestone can be used in corresponding industrial fields after being processed by crushing, screening, and drying processes. The drying is a key step in the production and processing of limestone, and the drying effect has an important impact on the quality of final limestone materials. Therefore, we must choose the proper limestone drying equipment. Our limestone dryer is specially designed according to the characteristics of limestone. With superior quality and reliable performance, our limestone rotary dryer is well received by customers at home and abroad.
Advantages of Limestone Dryer Machine
1. Reasonable design, reliable performance, high thermal efficiency, uniform drying and convenient maintenance.
2. Lifting board is installed in the drum, which increases the contact area between limestone and heat air, and greatly improves the drying efficiency.
3. The waste heat drying is adopted to realize the effective drying of limestone, saving more than 40% energy compared with ordinary dryers.
4. Special sealing device, perfect dust removal device and good thermal insulation system are adopted, which not only reduce the energy consumption, but also avoid the dust overflow and reduce the harm to operators.
5. The self-aligning supporting roller structure is adopted, and the supporting roller is well matched with the rolling ring, which greatly reduces the wear and power consumption.
6. Multiple heat sources can be selected, such as the clean coal, biomass, fuel gas, steam waste heat, etc.
Wide Application of Lime Stone Dryer
Lime stone dryer is used for drying slag, carbide slag, limestone, clay, river sand, iron ore, quartz sand, water slag, ore powder, ore concentrates and other mineral materials. It is widely applied in building materials, metallurgy, mineral processing, paper making, printing ink, chemical industry, rubber, cement and other industries.
Structure of Complete Limestone Drying System
The complete limestone drying system is mainly composed of rotary drum, induced draft equipment, high-speed dispersing equipment, lifting plate, self-cleaning device, transmission device, conveying equipment, hot air equipment, reducer, support device, sealing device, dedusting device, etc.
Limestone Drying Machine Working Principle
Limestone is sent to the hopper by the conveying equipment, and smoothly enters the drum through the inclined feeding pipe. The cylinder of limestone dryer rotates slowly, and has a certain inclination with the horizontal line. Limestone enters the cylinder from the higher end and slowly moves towards the lower end under the action of gravity. At the same time, the heat carrier is fed from the lower end and continuously moves towards the higher end, making reverse contact with limestone materials, and completing the drying of limestone in the process of contact.
