山東省における植物繊維改質用ターボミル
A turbo mill plant fiber modification line grinds and coats fiber in one machine. The RTM turbo mill breaks up fiber clumps and sprays the coupling agent inside the same grinding chamber, so the activation index reaches target while fiber length survives. Customer Background The customer processes crop straw fiber for biodegradable plastics and wood-plastic composites. The plant sits in Shandong and ships modified fiber to compounders and board makers. Before the project, the plant ran two machines. A mechanical mill reduced fiber size. A high-speed mixer coated the surface. A screw conveyor moved fiber from one to the other. The Challenge Ground plant fiber clumps. The fibers are hydrophilic, […]

ドレスデンにおける単結晶シリコンの超微粉砕
1. 背景 ドレスデンにある世界的な材料メーカーは、単結晶シリコン粉末をミクロンレベルの精度で、かつ狭い粒度分布（PSD）で超微粉砕する必要がありました。この顧客は半導体および太陽光発電業界に製品を供給しており、これらの業界では微粒子と粗粒子の両方の分画を厳密に制御することが必須条件となっています。従来の粉砕装置では、このレベルのPSD制御を実現することは困難な場合が多いです。原料はシリコン粉末で、試作用に約15kgが提供されました。顧客の主な懸念は微粒子の除去でした。他の技術を用いた以前の粉砕試験では、製品中に残留微粒子が多すぎました。 2. 粉砕目標 2つの製品仕様が定義され、それぞれが狭いPSD範囲を要求していました […]
ブラジルにおける天然黒鉛のD50 2.8μmへの超微粉砕
Project Background The client is located in the state of Minas Gerais, Brazil. It’s a company specializing in the deep processing of natural graphite. Its products are primarily used in the fields of conductive additives for lithium-ion batteries and specialty lubricants. The client needs to grind natural flake graphite to a D50 of approximately 2.8 micrometers, with a narrow and uniform particle size distribution to avoid the production of excessive ultrafine powder due to over-grinding. Production Challenges Graphite has a layered structure. It is soft and naturally lubricious. During conventional ball milling, interlayer slippage tends to occur rather than effective fracturing, resulting in high energy consumption and low efficiency during […]
オーストラリアの大手耐火材料メーカー向けガラス粉末の分類
As global building safety standards continue to rise, the Australian fireproof material market is demanding higher performance and customized particle size distributions for glass powder. As an inorganic flame-retardant filler, the particle size distribution of glass powder directly impacts the film-forming density of fireproof coatings and the glazing effect under high-temperature conditions. The Australian client is dedicated to developing a new generation of high-performance fireproof materials. The project required the precise separation of raw glass powder into ultra-fine powder (to improve coating smoothness) and coarse powder (to provide structural support). The client had stringent requirements for both production capacity and grading precision. Project Overview Technical Challenges & Solutions 1. Precision […]

Project Highlights A. Extreme Fineness Control Achieving D97 = 1.17μm means the vast majority of particles have reached the sub-micron level. The Epic Powder Jet Mill utilizes supersonic airflow to induce high-velocity collisions between particles. This “autogenous” grinding method eliminates contamination from grinding media, while the high-precision horizontal or vertical classifying wheel ensures […]
