Effiziente Siebung von Diammoniumhydrogenphosphat (DAP)

Fertilizer with high production rate and product purity

How do you achieve maximum product purity and high throughput rates when screening hygroscopic diammonium hydrogen phosphate (DAP)?
Diammonium hydrogen phosphate (DAP) is an essential component of many fertilizer compositions due to its high phosphorus and nitrogen content. When screening DAP, producers are faced with the challenge of ensuring fine and homogeneous particle sizes, while at the same time guaranteeing a high production rate and product purity.

Challenges in the sieving of DAP

Screening DAP is technically challenging as the material is hygroscopic, i.e. it absorbs moisture from the ambient air and has a tendency to form agglomerates. These agglomerations make it difficult for the material to pass through the screen meshes and impair the efficiency of the screening process. In addition, high throughput rates can lead to blinding and clogging of the screen mesh, which can result in the screening process having to be completely interrupted, bringing the entire production process to a standstill.

Precise screening using innovative technology

RHEWUM specializes in screening challenging materials such as DAP and offers tailor-made solutions for these tricky requirements. Our screening machines are characterized by their robust design and sophisticated screening technology, which enables efficient separation even under the most difficult conditions. The use of high-frequency vibration systems and precisely adjusted screen cloths achieves a high degree of separation efficiency, ensuring uniform particle size distribution.

A special feature of RHEWUM screening machines is the option of continuous cleaning of the screen decks, which prevents clogging and optimizes the material flow. This is particularly advantageous when screening hygroscopic materials such as DAP, as the screen meshes remain free of adhesive residue to ensure consistently high screening performance and continuous production.

In addition, the individual design of the RHEWUM machines enables easy adaptation to different production requirements and throughput quantities. The high precision and reliability of the machines help to ensure that DAP can be sieved in the desired quality and with minimal losses.

Conclusion

The screening of diammonium hydrogen phosphate poses a particular challenge due to its physical properties. With RHEWUM’s advanced screening machines, these difficulties can be effectively overcome. By combining high-frequency screening technology, continuous cleaning and customizable machine configuration, RHEWUM offers a solution that ensures consistently high product quality and efficiency in DAP production.

Screening drilling barite for hydraulic fracturing (fracking)
A facility in Louisiana, USA, has enhanced its barite processing for fracking by acquiring two RHEsonox screening machines and a RHEmid feeder, aimed at improving the efficiency and precision of barite screening. Barite, a mineral composed of barium sulfate (BaSO4), is commonly used in the oil and gas industry, especially in hydraulic fracturing (fracking) and drilling operations. In these contexts, barite serves as a weighting agent in drilling muds. The high density of barite helps to counteract the immense pressures found in oil and gas reservoirs. By adding barite powder to the drilling mud, the overall density of the mud is increased, which in turn helps to maintain the stability of the borehole, control formation pressures, prevent blowouts, and facilitate the extraction of oil and gas. In order to upgrade barite processing for fracking RHEWUM America Inc. recently delivered two RHEsonox® sieving machines that precisely screen barite with separations cuts of up to 325 mesh (50 μm) and a RHEmid feeder for uniform material distribution. The RHEsonox® high-performance screening machine utilizes two counter-rotating imbalance motors to create linear motion, facilitating

Screening machines for dedusting and classification of lignin
Screening machines optimize the quality of lignin by removing impurities and dust, classifying lignin pellets by size and eliminating lumps. Lignin is the second most common biopolymer on earth after cellulose. In the industrial processing of wood, especially in paper production, lignin is produced in large quantities as a by-product. In the past, this by-product was often burned to generate energy, but due to its chemical structure and properties, it is now used as a filler, additive, binder, reinforcing agent or adsorbent. The use of lignin in these and other applications is in line with the trend towards the bioeconomy, in which renewable, plant-based raw materials are used instead of fossil resources. Improved lignin quality Screening machines help improve the quality of the produced lignin and prepare it for specific applications or further processing steps: - Cleaning and separation: Lignin obtained from the pulping process of lignocellulosic materials may contain impurities or undesirable solid components. Screening machines can help to remove these impurities. - Classifying: Lignin particles
