Regarding the time cycle for drying and screening of ammonium metatungstate crystals, these times may vary due to specific production conditions and equipment differences. However, based on general industrial production experience and possible process flows, we can roughly estimate and summarize the time cycle:
Drying time cycle
- Drying method
Natural drying
The drying time depends on the ambient temperature, humidity, and initial water content of the crystals. Generally, drying may take hours to days.
Oven drying
Oven drying can be completed at a set temperature and time. Generally speaking, the drying temperature is set between 80°C and 100°C, and the time can range from a few hours to more than ten hours, depending on the water content of the crystals and the drying efficiency.
Spray drying
Spray drying is an efficient drying method that can be completed in a short time. The drying time is usually from seconds to minutes, depending on the performance and operating conditions of the spray dryer.
- Precautions
The temperature and time should be strictly controlled during the drying process to avoid excessive temperature causing crystal decomposition or excessive drying of the crystals due to long time and loss of activity.
Screening time cycle
- Screening equipment
The screening time depends on the type of screening equipment, screen mesh size, screening speed and crystal amount. Vibrating screens and rotary screens are common screening equipment, and their screening efficiency varies.
- Screening time
For general industrial production lines, the screening time is usually calculated in minutes or hours. The specific time depends on the amount of crystals and the processing capacity of the screening equipment.
- Precautions
During the screening process, it is necessary to ensure the cleanliness of the screening equipment to avoid contamination of the ammonium metatungstate crystals.
Check and replace the screen regularly to ensure screening efficiency and screening quality.
Drying time cycle
From a few hours to a few days (natural drying) or a few hours to more than ten hours (oven drying), spray drying can be completed in seconds to minutes.
Screening time cycle
In minutes or hours, depending on the amount of crystals and the processing capacity of the screening equipment.
Please note that the above time cycle is for reference only and may be different in actual production. Therefore, in actual operation, it should be adjusted and optimized according to specific circumstances.
