Hot-air fluidized bed systems are commonly used in the production of rubber extrusions to cure the material. These systems utilize a fluidized bed of hot air to heat and cure the rubber extrusions.

The process begins with the rubber extrusions being loaded onto a conveyor belt and passed through a preheating zone. In this zone, the extrusions are gradually heated to the desired temperature to ensure even heating throughout the extrusion.

The extrusions then enter the fluidized bed of hot air, where they are continuously agitated and mixed by the flowing air. This agitation ensures that the extrusions are heated uniformly and the curing process is thorough.

The temperature of the hot air is carefully controlled to ensure that the rubber is cured to the desired hardness and strength while maintaining consistency in the product. The curing process may take several minutes, and the temperature is maintained until the curing is complete.

Hot-air fluidized bed systems offer several advantages for curing rubber extrusions. Firstly, they provide rapid and uniform heating of the rubber compound, ensuring that it is cured evenly throughout. Secondly, the use of hot air ensures that the curing process is thorough, resulting in a more durable and long-lasting product.

Moreover, hot-air fluidized bed systems can be easily controlled, allowing manufacturers to adjust the curing process to produce rubber products with specific properties. This method of curing is also energy-efficient compared to other methods, as the heat is transferred directly to the rubber extrusions, minimizing heat loss.

Overall, hot-air fluidized bed systems are a highly effective and efficient method for curing rubber extrusions, producing high-quality rubber products with consistent properties.
