Calcite powder air conveying system, the crucial part in the whole calcite grinding mill, is designed for close distance and continuous transporting while takes Roots blower as the air source.
Its horizontal transporting distance is under 300 m, vertical distance is under 30 m. This air conveying system is suitable for conveying powder which size is no less than 60 mesh and the moisture content is no more than five per cent.
Working principle of this conveying system
This system adopts the principle of gas-solid flow fluidization. Meanwhile, it is based on the general consideration of jet technology and differential pressure theory. Taking the electric rotary feeder ad the feeding device, the material is evenly put into the mixing chamber. While its fluidization, the high-speed air flow which happened due to the Roots blower sends the mineral powder into acceleration chamber, and the suspension flow goes into the silo through conveying pipeline. After the mineral is separated, the powder falls into the silo while gas is released to the atmosphere.
The calcite powder air conveying system is designed for the whole calcite processing plant. This system can be adjusted when the factory size is different. Its sealed design keep the factory away from dust pollution. The quality of calcite powder can be guaranteed during the conveying flow since the system is capable of protecting the calcite powder from damping, pollution and mixing with other materials.

Our calcite grinding mill can fulfill the needs of high-yield calcite powder( between 200 to 2500 mesh) production in non-pollution work environment. Crushing, further grinding, surface coating, packing can be all accomplished in one continuous system. As for the first stage-crushing, jaw crusher and hammer mill can be chosen by yourself while our engineers will provide the professional suggestion. The second stage-further grinding can also be equipped with two different calcite ultra fine grinding mills and they are calcite micro powder mill and ultra fine calcite vertical mill. In addition, our engineers will guide the machine installation in the clients factory and help with the maintenance if necessary.
If you have any problem of this calcite air conveying system or the whole calcite powder production line, you can contact us at any time. Chatting with us online or leaving messages on our website can be a good choice. The feedback will be within 12 hours.
