Optimizing NdFeB Powder Processing: The Critical Role of Nitrogen/Argon-Protected Jet Mills in Preventing Oxidation and Enhancing Efficiency
The application of nitrogen/argon-protected jet mills in the ultrafine grinding of neodymium iron boron (NdFeB) materials. NdFeB magnets are known for their high magnetic energy and strength. They are crucial in many industries, including electronics and renewable energy. Processing them into ultrafine powders is tough. This is because they are highly reactive, pyrophoric, and prone […]
Application of precipitated calcium carbonate in coating
Precipitated Calcium Carbonate (PCC) is a versatile additive in coatings, offering several functional benefits due to its controlled particle size, shape, and purity. Production of PCC and PCC for coating Calcium carbonate is the most common mineral on the earth’s surface, besides quartz. It exists in three different mineral forms: calcite, aragonite and vacerate. Calcite […]

Hollow glass microspheres (HGM), as a filler in composite materials, have been widely applied in fields such as coating and painting, specialty materials, and resource exploration due to their lightweight, hollow structure, thermal insulation, and chemically stable properties. In recent years, within the coatings industry, researchers have significantly addressed challenges such as poor interfacial compatibility […]
How Jet Mills Maintain a Low Grinding Temperature: A Comprehensive Technical Analysis
Jet mills achieve precise temperature control through adiabatic expansion cooling, a thermodynamic process where compressed gas (air/N₂/CO₂) rapidly expands through nozzles, absorbing heat from the grinding chamber. As high-pressure gas accelerates to supersonic speeds and expands into the low-pressure chamber, its temperature plummets (e.g., from 25°C to -45°C at 6 bar), creating an in-situ cooling […]

Jet mills work best on materials with certain physical properties. They help to mill the materials effectively. Here are the key factors and examples of suitable materials: Key Characteristics for Jet Milling Brittleness and Hardness Brittle Materials: They are ideal for jet milling. They fracture easily under high-speed impacts. This property enables the production of […]
Polypropylene filling modification, these 7 kinds of mineral powders have their own strengths
Polypropylene (PP) is a popular thermoplastic polymer. It is vital in packaging, appliances, and auto parts. Its easy processing and great properties make it useful. PP still has some limits. It has high heat shrinkage, low performance in cold, and poor impact resistance. These problems have led people to add inorganic mineral powders to it. […]
How does the particle size of pharmaceutical powders affect the bioavailability of drugs?
The particle size of pharmaceutical powders greatly affects drug bioavailability. This is mainly reflected in these aspects: Dissolution rate Smaller drug particles have a larger surface area. This speeds up their dissolution in body fluids. For low-solubility drugs (BCS Ⅱ/Ⅳ class), reducing the particle size can greatly increase their solubility. This speeds up the drug’s […]
