Titanium dioxide drying process introduction:
Titanium dioxide production is a very fine chemical processing process with high product quality requirements. Titanium dioxide has stable physicochemical properties and many excellent properties. Titanium dioxide is an indispensable raw material in various industries such as pigments, light industry, electronics, chemical industry and metallurgy. According to the characteristics of titanium dioxide materials, combined with the company's own intellectual property rights, the development of the special titanium dryer special dryer, and in 2001 was the first in China to successfully apply to rutile titanium dioxide drying. Our company can design special processes according to the characteristics of materials and related technical parameters.
product description:
According to the characteristics of titanium dioxide powder, combined with the company's own intellectual property rights, the development of the special titanium dryer, this machine can effectively solve some of the drawbacks of the past general drying equipment, such as adhesives and other drawbacks. It can effectively improve the utilization efficiency of equipment and improve the cost performance of equipment, so as to maximize the utilization of enterprise efficiency costs.
working principle:
The heater output heating gas enters the interior of the dryer in a tangential direction through the bottom swirler of the Sed dryer, and generates a high-speed swirling updraft. After the diaphragm press presses the TiO2 filter cake into the main machine through the screw feeder, the bulk material is dried by continuous crushing, dispersing, boiling and high-speed mass transfer and heat transfer under the action of the high-speed swirling ascending airflow and the mixer at the bottom of the main unit. . The dry qualified material is taken out from the upper outlet of the dryer by the airflow, and the dried product is obtained after being collected; the material with too large or high humidity is arranged in the upper part of the drying chamber to block and continue to be further dried in the drying chamber until It is taken out by the airflow, and the purified exhaust gas is led out by the high-pressure induced draft fan.
Performance characteristics:
1. Continuous production, the machine system is an efficient and energy-saving drying equipment integrating drying, dispersing and grading.
2. Once the original particle size is reached, there is no need to pulverize again, and the product quality is stable.
3, fully enclosed negative pressure operation, no dust leakage, product recovery rate of up to 99.9%, the working environment meets national environmental requirements.
4, using automatic gas (natural gas, fuel) burners, fully burning gas (natural gas, fuel) direct heating hot air stove.
Technical specifications: Annual output of the series within the scope of series specifications: 30,000 tons, 50,000 tons, 80,000 tons, 120,000 tons.
