Introduction The production of pharmaceutical-grade gypsum powder (Calcium Sulfate Dihydrate, USP/EP grade) represents one of the most demanding applications in powder processing. Unlike industrial-grade gypsum, pharmaceutical-grade material must meet stringent criteria for purity, particle size distribution (PSD), chemical stability, and microbiological control. The selection and operation of the milling equipment are, therefore, not merely a […]
Introduction The production of high-purity, chemical-grade gypsum powder (calcium sulfate dihydrate, hemihydrate, or anhydrite) is a sophisticated industrial process demanding precise control over particle size distribution, whiteness, chemical purity, and crystalline structure. This fine powder is a critical raw material in diverse sectors, including construction (plasters, self-leveling compounds), pharmaceuticals (tablet excipients), food (coagulant, calcium fortifier), […]
Introduction The production of high-performance paint additives, particularly those based on gypsum (calcium sulfate), demands precise control over particle size, distribution, and purity. The choice of grinding mill is a critical decision that directly impacts product quality, production efficiency, and operational costs. Gypsum, when finely ground, acts as a functional filler, extender, and rheology modifier […]
Introduction The paper industry is a cornerstone of modern communication and packaging, constantly evolving to meet demands for higher quality, improved sustainability, and cost efficiency. A critical component in this evolution is the use of functional additives, with gypsum (calcium sulfate) emerging as a vital material for both filler and coating applications. Gypsum additives enhance […]
Introduction The production of high-performance rubber products often relies on the incorporation of finely ground functional additives. Among these, gypsum (calcium sulfate) plays a crucial role as a filler, flame retardant, and processing aid. The efficacy of gypsum in rubber compounding is directly linked to its particle size, particle size distribution (PSD), and purity. Achieving […]
Introduction The production of high-quality plastic products often relies on the incorporation of functional additives to enhance properties such as flame retardancy, dimensional stability, and mechanical strength. Gypsum-based additives, particularly in finely ground forms like calcium sulfate (CaSO4), play a crucial role in this sector. Selecting the optimal grinding mill for processing these additives is […]
Introduction The production of high-quality gypsum board is fundamentally dependent on the consistent supply of finely ground, chemically stable gypsum powder. A modern gypsum powder manufacturing plant is a sophisticated integration of material handling, size reduction, thermal processing, and classification technologies. This article outlines the core processes of a complete production line for gypsum board […]
Introduction The production of high-quality cement-grade gypsum powder is a critical process in modern cement manufacturing, serving as a vital set regulator to control the setting time of cement. An efficient and reliable production line is paramount to ensure consistent product quality, optimal energy consumption, and environmental compliance. This article delves into the core processes […]
Introduction Producing high-quality gypsum powder, particularly at a fineness of 380 mesh (approximately 40 microns), requires precise and efficient grinding technology. The choice of grinding mill directly impacts product quality, production efficiency, energy consumption, and overall operational costs. This guide provides a comprehensive analysis of the key factors to consider when selecting equipment for 380-mesh […]
