DESCRIPTIONS

After the catalyst filter material is shaped (short strip with adjustable diameter and length) by a molding machine (hydraulic extruder), it is evenly spread on a low-temperature belt drier mesh belt (with adjustable paving thickness). The low-temperature belt machine pre-dries the material by the heat provided by steam heating or electric heating, and the drying time is adjustable. The dry material falls into a high-temperature belt roast furnace through a conveyor or a height difference, that material is evenly spread on a mesh belt by a distribution structure of the roasting furnace, the high-temperature belt conveyor roasts the material through heat provided by natural gas heat (tail gas can be recycled) or electric heating, the rear end of the high-temperature belt roasting furnace is provided with a cooling section, and the cooled material can be directly packaged or transferred to the next working procedure.

FEATURES

◎ Both dryer and roaster adopt cross-flow technology, which improves production efficiency and reduces energy consumption.

◎ The introduction of foreign advanced rectification devices has improved the stability of the roaster operation and the service life of the mesh belt.

◎ The contact specific surface area between materials and hot air is large, and the heat transfer coefficient is high.

◎ Short moisture migration distance, uniform heating and uniform drying of materials.

◎ Energy saving is about 30% compared with traditional belt drier and belt roaster.
