Key points and skills for river sand dryer operation

Q1: What key parameters should be paid attention to when operating a river sand dryer?

A1: Key operating parameters include: 1) hot air temperature, usually controlled at 400-600℃; 2) drum speed, which affects the material residence time; 3) feed speed, which needs to match the drying capacity; 4) air volume, which affects the heat exchange efficiency; 5) discharge moisture, which reflects the drying effect. These parameters need to be optimized according to material characteristics and product requirements.

Q2: How to optimize the process parameters of the river sand dryer?

A2: The optimization of process parameters can be started from the following aspects: 1) Determine the optimal temperature-time curve through experiments; 2) Adjust the drum speed according to material characteristics; 3) Optimize the feed speed to improve equipment utilization; 4) Adjust the air volume to balance energy consumption and drying effect; 5) Use the online monitoring system to adjust parameters in real time. Continuous data accumulation and analysis are important foundations for optimization.

Q3: What are the safety precautions when using a river sand dryer?

A3: Safety precautions include: 1) Check whether all safety devices are normal before operation; 2) Ensure that the ventilation system is in good operation to prevent dust accumulation; 3) Wear protective equipment to avoid high temperature burns; 4) Conduct safety training regularly to improve the safety awareness of operators; 5) Develop emergency plans to ensure that emergencies can be handled in a timely manner. Safety is the primary prerequisite for production and must be taken seriously.
