European trapezium mill
A trapezium roller mill that draws on proven European grinding design — bevel-gear drive, internal thin-oil lubrication and a curved air channel for steady airflow. A versatile mid-fine mill across a wide range of non-metallic minerals, and the natural replacement for traditional Raymond and pendulum mills.
What it does and where it fits
The European trapezium mill grinds material between trapezium-profile rollers and a grinding ring, with the finished powder carried up to a classifier and on to collection. A bevel-gear direct drive keeps the transmission compact, an internal thin-oil system lubricates the main bearings, and the curved air channel cuts airflow loss for higher grinding efficiency. It configures readily into a full system with feeder, classifier, collector and control cabinet.
- Bevel-gear direct drive — compact transmission and smooth running.
- Internal thin-oil lubrication for the main bearings — simpler upkeep.
- Curved (arc) air channel reduces airflow loss and lifts grinding efficiency.
- Configures into a full system with feeder, classifier, collector and control cabinet.
What sets it apart — point by point
Mature and stable equipment
Built on decades of mill manufacturing experience across four generations of grinding mills — proven in the field.
Advanced transmission
Super-power bevel-gear integral transmission for compact, smooth and high-torque running.
Thin-oil lubrication of transmission
Both the main shaft and blower driving systems are thin-oil lubricated, with an oil-change interval of around four months — low cost and low maintenance frequency.
High blower configuration
The blower also adopts thin-oil lubrication with around four months between oil changes.
Variable-frequency separator, higher precision
A new hanging cage-type powder separator with variable-frequency drive gives finer control of finished powder fineness.
Leading technology, low running cost
Derived from the latest European grinding technology with multiple patents. High efficiency and low running cost — the leading equipment in the pendulum mill industry.
Multiple functions, economical investment
Grinds a variety of minerals to meet many specification and particle-size needs. Low infrastructure cost and economical investment.
High efficiency and large capacity
Single-machine processing capacity up to 60 t/h, breaking through the capacity bottleneck of traditional pendulum mills.
Integrated comprehensive solution
Proprietary experimental devices support an integrated solution covering design, supply, construction and service.
Energy saving and environmental protection
Certified to national environmental protection standards for industrial products.

Material in, finished powder out — the running flow
Crushing
Raw material is crushed by a jaw crusher to the required feed size before entering the mill.
Feeding
Crushed material is lifted into the hopper and metered evenly and continuously into the grinding chamber by an electromagnetic vibrating feeder.
Ring & roller grinding
Inside the chamber, the trapezium-profile rollers and grinding ring crush the feed into powder; the curved air channel carries ground powder upward.
Classifying
The variable-frequency cage separator classifies the rising powder; on-spec fines pass through while coarse particles fall back for regrinding.
Collection
Finished powder enters the cyclone collector and drops to the discharge; exhaust air is cleaned by a pulse dust collector before release.
