The HGM micro-powder grinding mill, also known as a three-ring medium-speed micro-powder mill. It can process ultra-fine powder of materials with Mohs hardness < 9.3 such as limestone, calcite, dolomite, talc, feldspar, coal gangue, ceramics, and coal. The fineness of the finished powder ranges between 325-2500 mesh.

Formally known as the HGM Series Micro-powder Grinding Mill, this machine serves as a high-efficiency and refined upgrade to traditional micro-powder grinding equipment. Its core positioning targets medium-to-large-scale non-metallic mineral powder processing lines, focusing on ultra-fine powder production. Its objective is to consistently produce ultra-fine powders ranging from 80 to 2500 mesh (approximately 0.005–0.18 mm) with high grinding efficiency, low energy consumption, and stable operational performance.
Simply put, it currently stands as the preferred choice for ultra-fine powder processing of medium-hard materials such as calcite, barite, and limestone.
• Equipment Type: Ultra-fine micro-powder grinding mill (positioned between traditional Raymond mills and large-scale vertical grinding mills).
• Product Fineness: 80–2500 mesh (approx. 0.005–0.18 mm), adjustable according to production needs.
• Core Value: While ensuring high powder fineness and production efficiency, the mill reduces unit energy consumption through optimized structural design.
• Applicable Materials: Limestone, calcite, barite, gypsum, bentonite, kaolin, coal, and other medium-hard materials.
• Industry Applications: Non-metallic mineral deep processing, building materials production, chemical industry powder preparation, and ultra-fine powder production for food, medicine, and other fields.
Patented technology, with an Inner automatic thin-oil lubricating system, and a long oil change cycle.
This powder separator adopts variable frequency speed control for precise fineness adjustment, and boosts the grinding roller’s grinding force by 15%–20%.
It needs fewer bearing replacements and delivers a longer service life, with its total working lifespan reaching 3–5 times that of conventional grinding mills.
At equal output capacity and powder fineness, it costs more than 80% less than jet mills. Superior wear resistance effectively prolongs the overall service life of the equipment.
• Machine Positioning : Classified as a large-scale vertical grinding equipment, it occupies an intermediate position between medium-speed trapezoidal mills and heavy-duty ball mills. It is primarily utilized to grind materials into ultra-fine powder (80-2000 mesh), with stable grinding performance and low energy consumption, serving as a core equipment for large-scale powder processing production lines.
• Working Principle: Materials are evenly fed into the center of the grinding table, and under the action of centrifugal force, they move outward to the grinding area. The grinding rollers press tightly against the grinding ring, realizing high-efficiency grinding through rolling compression. The fine powder is carried by the air flow to the classifier for screening, and the qualified powder is collected, while the unqualified powder falls back to the grinding area for re-grinding.
