Kaolin rotary flash drying machine
Working principle
At the bottom of the kaolin rotary flash dryer, larger and wetter particle clusters are mechanically crushed under the action of the agitator, while particles with lower moisture content and smaller particle size are carried up by the rotating airflow and further dried during the upward process. Due to the rotational flow of the gas and solid phases, the inertia of the solid phase is greater than that of the gas phase, and the relative velocity between the solid and gas phases is relatively large, which enhances the mass and heat transfer between the two phases. Therefore, this machine has a high production intensity.
Product Features
High efficiency, fast speed, small equipment for large-scale production : The flash dryer achieves high efficiency and fast production results through high circumferential gas velocity and short material residence time, meeting the demand for small equipment for large-scale production .
To prevent material from adhering to the wall and deterioration of heat-sensitive materials : The dryer is equipped with cyclone plates and classification rings inside, which can effectively prevent material from adhering to the wall, and in the high-temperature zone, heat-sensitive materials are specially designed to avoid coking and discoloration .
Multiple feeding device options : The flash dryer offers a variety of feeding devices, ensuring continuous and stable feeding without bridging during the process .
Control moisture and particle size of the material : Installing cyclone plates and classification rings in the drying chamber can control the particle size and moisture content of the material at the outlet to ensure uniform product quality .
Suitable for a variety of materials : Particularly suitable for high moisture content materials such as pastes and filter cakes, the moisture content of the materials can be up to 85% or more, and the moisture content of the final product can be controlled to 0.5% or less .
Structural design and operational reliability : An inner cone structure is set at the bottom of the drying chamber to shorten the length of the cantilever part of the stirring shaft and increase operational reliability; Scrapers are set on the stirring teeth to prevent the materials from adhering. A cooling jacket is set at the hot air inlet of the cone bottom to prevent material from deteriorating .
