Grinding Aluminum Hydroxide for Artificial Stone and Solid Surface: Particle Size, Purity, and Equipment Selection

Solid-surface countertops and artificial marble sheets rely on aluminum hydroxide (ATH) as their main mineral filler. The grinding step fixes the particle size distribution, and that distribution controls the cured slab’s translucency, color depth, resin demand, and surface texture. This article explains the target size ranges for solid-surface ATH and the equipment choices that hit […]
Turbo Mill vs Pin Mill: Which Is Better for Medium-Fine Grinding?

Choosing the right grinding mill affects particle size, energy use, and maintenance costs. If you are comparing impact mills for medium-fine powders, two designs come up again and again: the pin mill and the turbo mill. Choose a pin mill when you need flexible medium-fine grinding, frequent product changeovers, and lower maintenance. Choose a turbo […]
How to Choose the Right Grinding Equipment: A Complete Guide by Material Type

Buying grinding equipment starts with the wrong question most of the time. Buyers ask which mill is best before they ask what the material actually needs. The right sequence is the opposite. First define the material properties, then the target particle size, then the production scale, and only then match the machine. At Epic Powder […]
Pin Mill vs Air Jet Mill: Which Is Right for Your Material?

Introduction When a grinding process goes wrong, the most common cause is not a bad machine. It is the wrong machine. If any one of the four key requirements, target particle size, material properties, throughput, and operating cost, does not match the equipment, you will see problems such as off-spec particle size, high energy use, […]
What Is the Pin Mill 630C Dual-Drive Ultrafine Grinding Mill?

What Is the Pin Mill 630C? The Pin Mill 630C is a dual-drive high-speed impact mill from Epic Powder Machinery, designed with input from German engineers. The “630” refers to the 630 mm grinding disc diameter, and the “C” indicates the dual-drive configuration, where both the upper and lower discs rotate in opposite directions. In […]
Porous Carbon Milling: How to Choose Between Pin Mills, Air Classifier Mills, and Jet Mills

Most people judge a milling result by its D50. For porous carbon, that number can be misleading. The value of porous carbon comes from the pore network inside each particle, not from how fine the particle becomes. Those pores collapse if grinded too hard, the specific surface area drops. So before choosing a mill, it […]
Jet Milling for 3D Printing Materials: How a Jet Mill Produces Print-Ready Powder

Powder-bed 3D printing is moving out of the prototype lab and into serial production, and the powder feeding those printers is the fastest-growing link in that supply chain. According to Global Market Insights, additive manufacturing with metal powders grew from 650.8 million USD in 2025 to an estimated 813.8 million USD in 2026, on a […]
How Much Does a Jet Mill Cost? Price Guide 2026

Jet mill pricing, operating costs, and total cost of ownership compared, from lab-scale units to full industrial production systems. Epic Powder MQW60 Horizontal Fluidized Bed Jet Mill When evaluating a jet mill purchase, the first question is usually: “How much does it cost?” Jet mill pricing is not one-size-fits-all. Unlike commodity equipment, jet mills are […]
Why Zirconia Grinding Media Isn’t Always the Right Choice for Stirred Ball Mills

In the powder processing industry like electronic pastes, the stirred ball mill is a core piece of equipment. When selecting grinding media and liner materials, many people will choose zirconia. It’s wear-resistant, chemically stable, and has a balanced density. This mindset is extremely common in real-world production, but it’s also the root of quite a […]
