Mineral product dryer (drying) is a type of dryer that processes large amounts of materials. Due to its reliable operation, high operational flexibility, strong adaptability, and large processing capacity, it is widely used in building materials, metallurgy, food, chemical industry, coal, medicine and mineral resources. Quartz sand dryer and feldspar powder dryer belong to mineral product dryer. It is generally suitable for granular materials and can also be used for drying sticky paste like materials or materials with high moisture content by partially adding materials. Especially for dried mineral products, they have high production capacity, wide adaptability, low flow resistance, large allowable fluctuation range in operation, and easy operation.

The water evaporation capacity of a rotary dryer is generally 30-80 kg/m3 · h; It increases with the increase of hot air temperature and changes with the moisture properties of the material. It has higher evaporation intensity than flash drying and spray drying. The thermal efficiency is generally between 40% and 70%. The equipment runs smoothly and reliably, with no vulnerable parts, few faults, and a long service life, and is widely used in various drying industries.

1. In terms of raw material form, centrifugal dehydration filter cake and pressure filtration filter cake; Drying of freely flowing materials such as powders, particles, flakes, fibers, etc.
2. From the application scope of materials, it is widely used in the drying of mineral products, building materials, chemical products, compound fertilizers, organic powders, feed, wine tanks, starch residue, corn residue, soybean residue, etc.
3. From the mechanism of the rotary drum dryer, it can be divided into various structural forms such as direct, indirect heating, ventilation pipe heating, steam pipe indirect heating, and compound heating.
4. In terms of drying temperature, it can be selected from the range of 60 ℃ -600 ℃. In principle, the higher the temperature, the higher the evaporation intensity. Therefore, the equipment has a small size, low investment, and low unit energy consumption.
