White Carbon Black Calciner:
Introduction:
White carbon black is a white powdery substance with porosity, and its chemical formula is SiO2-nH2O. The wet
feed of white carbon black has a high water content, but it requires a low final water content. However, conveying
the wet feed is inconvenient due to its low mass and granularity, which makes dehydration difficult. Our company
has supplied dehydration systems to dozens of domestic white carbon black manufacturers and gained rich
experience in this field.
Titanium dioxide dryer:
Introduction:
The heated air passes through the swirler at the bottom of Sid dryer and then enters the drying chamber
tangentially, forming a high-speed swirling upstream. The screw feeder conveys titanium dioxide filter cakes into
the drying chamber, where they undergo quick heat and mass transfer, being crushed, dispersed, boiled, and
dehydrated in the high-speed swirling upstream together with stirring from the blender at the bottom of the
drying chamber. The airflow carries away the dehydrated and qualified material to be collected as dried product at
the top outlet of the dryer. Oversized or highly humid materials are intercepted by a conical plate set on the
upper part of the drying chamber and rebounded back to undergo subsequent dehydration until carried out
through an outlet by airflow. The purified tail gases are expelled into the atmosphere by a high-pressure draft fan.
Technical process:
Performance & features:
1. The Sid Titanium Dioxide Special Dryer is an efficient dehydration equipment that combines drying, dispersing, and sizing into a complete system for continuous production.
2. Once the required granularity is achieved, there is no need for additional crushing operations. The product quality remains stable.
3. The operation is enclosed with subatmospheric pressure to prevent dust leakage. The product recovery rate reaches 99.9%, and the working environment meets the requirements.
4. A direct heating hot-blast stove is used, utilizing coal gas, natural gas, or fuel oil. The combustion system has automatic control for energy efficiency purposes.
Technical specification:
The annual output of a single unit is 30,000 tons, 50,000 tons, 80,000 tons, or 120,000 tons.
