人工石およびソリッドサーフェス用水酸化アルミニウムの粉砕：粒度、純度、および装置の選定
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 them. Engineered Stone Has Different Filler Families Engineered stone is not a single material. Quartz stone uses quartz powder as its main filler; solid surface, also called artificial marble, uses ATH; and some lower-cost organic artificial stone uses calcium carbonate. Each filler gives the slab different optics, hardness, and processing behavior. We have covered quartz […]
ターボミルとピンミル：中微粉砕にはどちらが適しているか？
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 mill when you need continuous fine grinding with built-in air classification and better temperature control. Both mills grind by impact. The difference lies in how they classify particles, manage heat, and fit into your production workflow. What Counts as Medium-Fine Grinding? Medium-fine grinding usually targets particle sizes between 5 microns and 150 microns. Industries such […]
適切な研削装置の選び方：材料タイプ別完全ガイド
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 Machinery we build jet mills, ball mills, pin mills, and air classifiers. This guide walks through the four material groups that drive most grinding inquiries, and how to match each one to the right machine. The four questions that decide everything Before comparing models, answer these four questions. They eliminate most bad choices. How hard […]
ピンミルとエアジェットミル：どちらがあなたの材料に適しているか？
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, heat damage, or metal contamination. Pin mills and air jet mills are two widely used fine grinding machines. They work on different principles and suit different materials and applications. This article explains how each one works, compares them on the points that matter, and introduces the matching product lines from Epic Powder Machinery. It is […]
Pin Mill 630Cデュアルドライブ超微粉砕機とは何ですか？
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 a standard single-drive pin mill, one disc rotates while the other stays fixed. The 630C drives both discs, so the relative speed between the pin arrays is the sum of both disc speeds. This gives higher impact energy and shearing force, which helps when grinding hard materials or when you need a tight particle size […]
多孔質炭素の粉砕：ピンミル、エアークラシファイアミル、ジェットミルの選び方
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 is worth asking how much of its surface area survived the process. Why Porous Carbon Is Not Just Another Powder As a silicon carbon anode host, porous carbon typically carries a Gurvich total pore volume of 0.1 to 0.3 cm³/g and a BET surface area of 50 to 200 m²/g. Commercial resin based grades go […]
3Dプリンティング材料のためのジェットミル：ジェットミルが印刷可能な粉末を生成する方法
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 path to 2.9 billion USD by 2035 at a 15.4 percent compound annual growth rate. Powder is also the dominant material form, holding a 63.7 percent share of the 3D printing metal market in 2026, with powder bed fusion as a leading technology route. That growth raises the bar on powder quality. A printer can […]
ジェットミルの価格はいくらですか？価格ガイド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 configured for specific materials, throughput targets, and particle size requirements. The price of a system that grinds battery-grade graphite to D50 = 3 µm is very different from one that processes industrial minerals to D97 = 45 µm. Below we break down real price ranges across different scales, the six key factors that drive cost, […]
ジルコニア製粉砕媒体が攪拌式ボールミルに必ずしも最適な選択肢ではない理由
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 few hidden problems. Zirconia is indeed a material with excellent overall performance, but it’s by no means a universal solution for every process. Blindly trusting zirconia often leads to product contamination, poor grinding efficiency, and sometimes even scrapping an entire batch of material. In this article, we’ll explore why zirconia isn’t a cure-all and how […]
