Pumice stone, also known as light stone or floating rock, has many pores, light weight, high strength, acid and alkali resistance, corrosion resistance, and is pollution-free, non radioactive, etc. It is an ideal natural, green, and environmentally friendly product. The pores inside the damp pumice are filled with water, which has a high density and cannot float on water. Therefore, it is necessary to first allow air to refill. The pumice dryer is a key equipment for drying pumice.

  Main functions of pumice dryer

  1. Reduce moisture: The pumice dryer can quickly evaporate the moisture in the voids of the pumice, refilling the air and reducing the weight of the dried pumice. It can float on water, the storage and transportation costs are saved.

  2. Improve efficiency: The pumice dryer is suitable for industrial production, it can quickly dry a large amount of wet pumice within several hours, 24 hours continuously working, will not being affected by the environment, greatly improving drying efficiency.

  3. Improve the final product quality: The moisture content of the dried pumice is uniform and controllable, the physical and chemical properties of the product are stable, and the quality is reliable.

  Floating stone dryer - rotary drum dryer

  The pumice dryer is developed based on the characteristics of pumice, and it is a tilted rotary drum. Wet pumice is fed into the drum, and as the drum rotates, it continuously rolls and scatters, coming into full contact with hot air. The moisture evaporates and is discharged from the discharge port. The floating stone drum dryer has a large processing capacity and can continuously process a large amount of floating stone raw materials, making it particularly suitable for industrial scale production.

  The application of pumice

  1. Construction industry

  Floating stones can be used as lightweight bone materials to manufacture lightweight concrete and lightweight mortar, thereby reducing the self weight of buildings and improving seismic performance; It can also be used as insulation material to improve the insulation effect of buildings.

  2. Ceramic production

  Floating stones can be used as one of the components of ceramic materials to improve the plasticity, ductility, plasticity, density, and hardness of ceramics, and enhance the performance and quality of ceramic products.

  3. Casting process

  Floating stone has excellent high temperature resistance and thermal conductivity, and can be used as a casting auxiliary material to manufacture molds, improving the fire resistance and thermal conductivity of casting molds.

  4. Metallurgical industry

  Floating stone has excellent resistance to high temperatures and thermal cycling stability. It can be used as a refractory mortar for the production of high-temperature furnaces, refractory bricks, and refractory coatings.

  In summary, pumice is a multifunctional mineral material with important applications in the fields of architecture, ceramics, casting, and metallurgy. The pumice dryer plays an important role in reducing the moisture content of pumice and ensuring product properties.
