Rotary flash dryer for titanium dioxide

Jun 19, 2024

Brief introduction of the case :Titanium dioxide rotary flash dryer is a set of drying, crushing, screening in one of the new continuous drying equipment, the material by the spiral feeder into the dryer, under the strong action of high-speed rotating stirring paddle, the material in the impact, friction and shear force under the action of dispersion, grinding, and hot air full contact, heat, dry ,The exhaust gas is discharged after being treated by the dust removal device, which meets the national GMP standard.

Titanium dioxide industry introduction:
Titanium dioxide is considered to be a white pigment with good performance in the world today, which is widely used in coatings, plastics, paper making, printing ink, chemical fiber, rubber, cosmetics and other industries. The global proportion of domestic titanium dioxide production capacity continued to increase, in 2017, the country's top 41 full-process titanium dioxide enterprises comprehensive output of 2.869,500 tons, the proportion of significantly increased.

At the same time that the market is expanding, the homogenization of titanium dioxide products is getting worse and worse, and the pressure on environmental protection is increasing sharply. In this situation, by improving the utilization of resources, to create an upgraded version of the titanium dioxide industry, has become the consensus of the industry.

Longxin pays attention to understanding and considering the needs of customers and the market, according to the characteristics of titanium dioxide and the actual market situation of the design scheme, on the basis of the original flash dryer, carried out technical improvements and innovations, launched a special rotary flash dryer for titanium dioxide.

Titanium dioxide rotary flash dryer equipment description:
Titanium dioxide flash dryer is a set of drying, crushing, screening in one of the new continuous drying equipment, the material by the spiral feeder into the dryer, under the strong action of high-speed rotating stirring paddle, the material in the impact, friction and shear force under the action of dispersion, pulverization, and hot air full contact, heat, dry, exhaust gas after dust removal device treatment after draining ,In line with national GMP standards.

Titanium dioxide rotary flash dryer equipment features:
1. swirl, fluidization, spray and grinding classification stage completed, drying time is only tens of seconds.
2. based on the titanium dioxide particle size has a certain effect on the color transmission, can be adjusted by adjusting the crushing speed and other ways to get dry spherical particles adjusted in accordance with the proportional size.
3. titanium dioxide particle size distribution seriously affects the performance, so in the drying process, the crushing quality can be controlled by adjusting the air volume and wind speed.
4. the high gas speed makes the residence time of titanium dioxide in the drying room short, which can effectively prevent the slight volatility of titanium dioxide at high temperatures.

Titanium dioxide rotary flash dryer technical advantages and improvements:
1. add a material opening on the flash main engine to facilitate the cleaning of internal blocked materials;
2. Change the cooling mode of the transmission mechanism to improve the service life of the titanium dioxide dryer;
3. change the arrangement of the heat exchanger main pipe, greatly improve the energy efficiency.

According to the particularity of materials and customer needs, our company has developed a special rotary flash dryer for titanium dioxide, which has a compact structure, small size and no site limitations. Dust can be collected, exhaust emissions meet the national GMP standards, reduce the environmental pressure of the titanium dioxide industry, dry finished products uniform particles, high purity, strong mobility, strong solubility, in the homogenization of titanium dioxide to show their own higher quality characteristics.

Application range of rotary flash dryer:
In the drying process, due to the impact of the material, shear, friction and particles, strengthen the mass and heat transfer, by the rotating air entrainment rise and further drying, so for paste, block materials, rotary flash dryer production intensity is higher. In the drying equipment of organic matter, inorganic matter, dye, food industry, etc., rotary flash dryer is well deserved the first choice.

Our company can manufacture rotary flash dryer according to customer requirements, welcome new and old customers to call to mail consultation, visit guidance, negotiate cooperation!
