Application of Apatite Vibrating Screen

Apatite vibrating screen is used for screening apatite, mainly because apatite materials have the characteristics of uneven particle size distribution, moderate hardness, easy agglomeration and many impurities. Ordinary screening equipment is difficult to achieve efficient and stable screening effect. The apatite vibrating screen drives the screen surface to generate high-frequency vibration through the excitation force, which can make the material quickly stratified and screened, improve the screening efficiency, and effectively prevent the phenomenon of blocking and adhesion. The equipment can be equipped with screens of different meshes (such as 10-20 mesh for phosphate fertilizer grading, 100-325 mesh for phosphate chemical fine powder screening), realizing the whole process screening control from coarse screening to fine screening.

What is the use of apatite vibrating screen?

Apatite vibrating screen is widely used in phosphate ore classification, phosphate fertilizer granulation screening, phosphorus chemical powder fine screening and desludging and impurity removal. In raw ore processing, it can efficiently remove unqualified particle size and improve crushing and flotation efficiency; in phosphate fertilizer production, it can control particle grade through screening and improve finished product consistency; in chemical processing, fine screening ensures powder purity and reaction efficiency; and in pre-packaging impurity removal and environmental dust removal, vibrating screens also play a key role. According to the material form and process requirements, vibrating screen equipment with different structures can be selected to achieve efficient, stable and low-consumption screening operations.

How to choose apatite vibrating screen

Primary screening of phosphate ore: After the phosphate ore is crushed, it needs to be screened to separate large pieces, qualified particle size and fine powder materials. Circular vibrating screen or drum screen is usually used at this stage

Phosphate fertilizer particle classification: In the process of phosphate fertilizer production, such as the granulation of superphosphate, ammonium phosphate and other products, linear vibrating screen or multi-layer vibrating screen is needed to classify and screen phosphate fertilizers of different particle sizes to remove oversized or overfine particles and improve the particle size uniformity and commodity grade of the product.

Phosphorus chemical powder impurity removal: In the production of phosphorus chemical raw material powder (such as calcium phosphate powder, iron phosphate powder, phosphate intermediates, etc.), the powder needs to be finely screened to remove agglomerates, agglomerate particles and impurities. This process often uses ultrasonic vibrating screens, which can effectively prevent fine powder from blocking the screen and improve the screening accuracy. The screen range is usually 100~325 mesh.

Specific application case of apatite vibrating screen

A large phosphate ore beneficiation plant: The apatite ore processed by the beneficiation plant has a low grade, and the ore properties are complex and contain a variety of impurities. In order to improve the recovery rate and concentrate grade of apatite, the ore needs to be efficiently screened and graded.

Equipment selection: The circular vibrating screen is selected as the coarse screening equipment to separate large pieces of ore and impurities such as soil in the raw ore; the linear vibrating screen is used as the fine screening equipment to further screen and grade the crushed ore, providing suitable feed for subsequent grinding and beneficiation operations. By adopting the combined screening process of circular vibrating screen and linear vibrating screen, the apatite recovery rate of the concentrator has increased by more than 10%, and the concentrate grade has also increased by about 5%.

Apatite is a common phosphate mineral, widely used in fertilizer production, chemical and metallurgical industries. The vibrating screen is mainly used to screen ores or powders of different particle sizes in apatite processing to meet the production process requirements.
