In the urea particle production process, screening is an important link to ensure product quality. The accuracy and efficiency of screening directly affect the purity and particle size distribution of urea particles. The gyratory sifter has become one of the ideal choices for urea particle screening due to its unique screening method and efficient processing capacity. We will discuss how to choose a gyratory sifter suitable for urea particle screening.
The gyratory sifter is suitable for screening fine particles with its efficient and precise screening performance. Its working principle imitates the action of manual screening. Through the combined movement of plane rotation and swinging, the material is evenly distributed on the screen surface, the screening time of the material is extended, and the screening efficiency is improved. Compared with traditional vibrating screen machines, the gyratory sifter machine has the following advantages:
High screening accuracy: suitable for fine screening of urea particle particles to ensure uniform particle size of the product.
Large processing capacity: able to cope with large material screening needs in large-scale urea particle production.
Low energy consumption: Compared with the vibrating screen, the gyratory sifter has lower energy consumption, which is conducive to saving production costs.
The screening requirements of urea particle granules are crucial to the selection of screens. Generally, the range of urea particle screening meshes is wide, and the appropriate screen specifications need to be selected according to the actual production needs. The following points need to be considered when selecting a screen:
Screen mesh: Select the appropriate mesh according to the particle size requirements of urea particle to ensure the accuracy of screening.
Screen material: It is recommended that corrosion-resistant and non-clogging screen materials, such as stainless steel screens, be selected, which can cope with the chemical properties of urea particles and extend the service life.
Mesh shape: Square or rectangular meshes are usually more suitable for urea particle screening because they help prevent particle clogging.
When selecting a gyratory sifter, you also need to pay attention to the specific parameters of the equipment to ensure that it matches the requirements of the production line.
Number of screening layers: urea particle screening usually requires multiple layers of screening equipment to achieve classification of different particle sizes. Select the appropriate number of screening layers according to needs.
Screening area: The screening area determines the processing capacity, and a sufficiently large screen surface needs to be selected according to the output requirements to ensure screening efficiency.
Vibration frequency and swing amplitude: Reasonable setting of the vibration frequency and swing amplitude of the equipment can effectively improve the screening effect of urea particle particles.
Urea particles will frequently contact the equipment during the screening process, so the selection of equipment material is crucial. The material of the gyratory screen machine should be corrosion-resistant and wear-resistant. It is recommended to use 304 or 316 stainless steel, which can effectively prevent urea particles from corroding the equipment and extend the service life of the equipment.
In order to ensure screening efficiency, it is necessary to check the condition of the screen regularly to avoid a decrease in screening accuracy due to blockage or damage to the screen. At the same time, the cleaning and maintenance of the equipment are also very important. The design of the gyratory sieve machine is usually easy to disassemble and clean, ensuring the hygiene requirements in the urea particle production process.
The gyratory sifter has become the best choice for the screening link in urea particle production with its high efficiency, energy saving, and precise screening performance. When selecting a gyratory screener, factors such as the screen, equipment parameters, price, and materials should be comprehensively considered to ensure that it perfectly matches the production needs and achieves the ideal screening effect.
