FGD gypsum recycling: securing future supply With coal plants being phased out the construction industry faces a gypsum supply challenge. Recycling becomes a crucial alternative.
FGD gypsum recycling: securing future supply
With coal plants being phased out the construction industry faces a gypsum supply challenge. Recycling becomes a crucial alternative. The global shift away from coal-fired power plants has significantly impacted the availability of Flue Gas Desulfurization (FGD) gypsum, a byproduct of these plants. With coal plants being phased out, particularly in countries like Germany where a complete shutdown is expected by 2038, the construction industry faces a gypsum supply challenge. Currently, more than half of Germany’s gypsum demand, approximately four million tons annually, is met through FGD gypsum. As natural gypsum sources are limited, recycling becomes a crucial alternative, with an estimated three to four million tons of gypsum waste available for recovery. Globally, FGD gypsum production is projected to peak around 2030, declining thereafter, especially in Europe, Japan, and potentially the USA. This shift presents both challenges, such as rising gypsum costs due to reduced FGD output, and opportunities, including a growing recycled gypsum market projected to reach $3.21 billion by 2030.

RHEWUM ScreenSpector: Modern Optimization of Screening Machines
The RHEWUM ScreenSpector app optimizes screening machine monitoring with tools like MeshConverter and VibSonic, available for iOS and Android. The RHEWUM app, known as ”RHEWUM ScreenSpector,” provides users of RHEWUM screening machines with tools for optimal utilization. Available for iOS and Android, it supports the operation and monitoring of screening machines with several key features: MeshConverter The MeshConverter simplifies the conversion of mesh sizes. It converts between DIN millimeters, inches, ASTM, and Tyler mesh units and offers advanced functions for calculating separation sizes for inclined screens. Users can input mesh sizes and angles to determine separation sizes in inches or millimeters. The tool supports calculations with any two values, making it a comprehensive solution for various screening scenarios. Additionally, the inclination angle (0°-45°) can be automatically determined using the smartphone’s sensors. VibSonic VibSonic transforms your smartphone into a powerful sound measurement device that measures sound levels across various frequencies. It calculates a mean

Quality-Focused Screening of Urea Prills Learn how a French urea prills manufacturer aims to address production challenges with a tailored screening approach.
Quality-Focused Screening of Urea Prills
Learn how a French urea prills manufacturer aims to address production challenges with a tailored screening approach. The Challenge: Ensuring Consistent Product Quality A prominent French manufacturer of urea prills faced a critical juncture in their production process. Their existing screening system, handling both uncoated and coated prills, struggled with persistent clogging in the lower deck and excessive dust in the final product. The manufacturer required exact separations for two fine screen cuts during loading screening, adhering to strict quality standards that permitted only a small percentage of undersized and oversized products. Developing a Quality-Focused Configuration RHEWUM’s engineering team conducted a series of in-depth screening tests to determine the optimal machine configuration. These tests focused on various screen designs, amplitudes, and frequencies to enhance separation efficiency and product quality. The aim was to develop a solution specifically tailored to overcome the quality challenges faced by the manufacturer. A Tailored Solution: Precision

Boost Bentonite Production Efficiency with Precision Screening Machine
Screening plays a crucial role in optimizing its functionality by controlling particle size to match the needs of specific applications. Bentonite, a versatile clay mineral valued for its absorbent and swelling properties, is essential across diverse industries. From drilling fluids to cosmetics, bentonite’s unique characteristics make it invaluable, yet challenging to process efficiently. Here’s an overview of bentonite’s applications and the specialized screening techniques that address processing challenges. Key Applications of Bentonite - Drilling Fluids: Bentonite is used in drilling for oil, gas, and water due to its ability to stabilize borehole walls, cool drill bits, and suspend cuttings. Fine particles (75-150 microns/ 100-200 mesh) are crucial here, as they prevent clogging and create a stable slurry. - Foundry Sand Binder: In casting molds, coarser bentonite particles (150-250 microns/ 60-100 mesh) ensure structural integrity and prevent excessive dust, helping molds retain their shape during metal casting. - Iron Ore Pelletization: Fine, uniform particles (45-150 microns/ 100-325

Precise separation of silica and silica gel The processing of silica and silica gel requires precise and specialized screening technology.
Precise separation of silica and silica gel
The processing of silica and silica gel requires precise and specialized screening technology. These materials, whether as a desiccant, carrier material or additive, pose complex challenges due to their specific properties such as different particle sizes, hygroscopic nature, dust formation and abrasiveness. Especially when used in food supplements, purity and gentle product processing are crucial. Screening ensures compliance with strict quality standards by classifying the materials into particle sizes and removing unwanted particles such as fine dust or oversized particles. This optimizes both further processing and the overall quality of the end product. Screening of silica powder and gel In the processing of silica and silica gel, screening machines are used in several production steps: - Dedusting: removal of fine dust (<0.1 mm/ 140 mesh) to minimize clumping and dust pollution. - Classification: separation into specific fractions, e.g. 0.1-0.5 mm (140 – 35 mesh) for powdery products or 1-6 mm (18-3 mesh) for granulates - Oversize separation:
