Dried ammonium metatungstate crystals usually need to be screened. The purpose of screening is to remove particles that do not meet the requirements, such as particles that are too large or too small, to ensure the uniformity and quality of the product’s particle size.
The screening process can include the following steps:
Select screening equipment
According to the production scale and product requirements, select appropriate screening equipment, such as vibrating screens, rotary screens, etc.
Set screening conditions
According to the particle size range required by the product, set parameters such as the screen aperture and screening speed of the screening equipment.
Screening
The dried ammonium metatungstate crystals are sent to the screening equipment for screening. During the screening process, particles that meet the requirements will pass through the screen, while particles that do not meet the requirements will be intercepted.
Collection and processing
The particles that meet the requirements are collected, and the particles that do not meet the requirements can be processed again or used as by-products according to the actual situation.
During the screening process, the following points need to be noted:
Ensure the cleanliness of the screening equipment
To avoid contamination of the ammonium metatungstate crystals.
Regularly check and replace the screen
To ensure screening efficiency and screening quality. Control the screening speed
Avoid too fast or too slow screening to cause poor screening effect.
In addition, after the dried material is screened through the screen, ammonium metatungstate powder with uniform particle size and high quality can be obtained. This process uses far-infrared heating and drying treatment, controlling the temperature range at 100-170℃, drying treatment time of 50-90 minutes, and sieving after cooling. The final material particle size can reach 15-20μm and is uniform.
In summary, the dried ammonium metatungstate crystals do need to be screened to ensure the uniformity and quality of the product particle size.
