Hot Gas Generator for Colored Sand: Carbotechnik supplies new system to Dorfner

A hot gas generator for colored sand must provide process heat quickly and reliably. Therefore, Dorfner GbR has once again chosen a Carbotechnik hot gas generator for a newly constructed production plant.

The new plant colors quartz sands with different grain sizes. The process involves several production steps. First, the plant feeds the sand into a fluidized bed apparatus. The system then introduces air from below. As a result, the air fluidizes the sand and keeps the material in constant motion.

Hot gas generator for colored sand with fast heat supply

During the fluidized bed process, a nozzle system sprays the required pigments and binder onto the sand. The plant then starts the heating phase. During this stage, the system heats the material to create the required coating on the sand.

The heat supply plays a key role in this process. For process-related reasons, the plant must receive the required hot gas without delay. The Carbotechnik hot gas generator therefore provides the necessary process heat quickly and reliably.

After the heating phase, the process enters a cooling phase. The plant then discharges the finished material. Afterward, the production cycle starts again with a new batch of quartz sand.

Precise process heat for colored sand production

The production of colored sand requires a controlled and reliable heat supply. In particular, the coating process must reach the required temperature quickly and maintain stable process conditions.

The Carbotechnik hot gas generator performs this important task. As a result, the plant receives a reliable heat source for the coating process. At the same time, the operator can monitor the relevant operating parameters and adjust them to the process requirements.

This combination provides fast heat generation and precise process control. Consequently, it creates an important basis for stable and repeatable production.

Carbotechnik supplies hot gas generator and control system

For the new plant, Carbotechnik supplied not only the hot gas generator for colored sand, but the complete hot gas generator system including its control system. Dorfner therefore received a coordinated solution from a single supplier.

In addition, Carbotechnik connected the system to the customer’s new process control system. A data interface provides communication between the two systems. As a result, the operator can access all process-relevant values and operating messages directly through the process control system.

This integration simplifies plant monitoring. Furthermore, it allows the operator to identify important operating conditions quickly and use the process data for further optimization.

Secure remote access supports maintenance and optimization

Carbotechnik also equipped the system with a secure remote connection. This feature provides an important advantage because the complete plant represents a prototype.

As with many prototype systems, the plant may require adjustments and optimization during operation. Carbotechnik specialists can now perform many of these tasks quickly through the secure remote connection.

Consequently, the service team can implement numerous adjustments without extensive on-site visits. This approach saves time and can also reduce service and optimization costs.

Efficient hot gas technology for demanding processes

The new hot gas generator for colored sand provides Dorfner’s production plant with a reliable and flexible heat supply. The combination of the hot gas generator, control system, process control integration and secure remote access creates a modern technical solution.

This setup supports Dorfner during the implementation of its new production process. At the same time, the digital connection enables Carbotechnik to respond quickly to future requirements.

Overall, the project demonstrates how Carbotechnik adapts hot gas generators and process heating systems to specialized industrial applications. Reliable technology, modern control systems and secure remote service create an efficient solution for demanding production processes.
