Gypsum grinding mill plant

Raymond mill (or suspension roller mill) is an efficient and energy-saving dry grinding equipment. It adopts a vertical structure and annular grinding principle. The material is crushed to 80-600 mesh (0.175-0.044mm) through the rolling action of the grinding roller and the grinding ring.

Core features: ​​

      Working principle: The material enters the grinding area through the feeder, and the grinding roller presses the grinding ring under centrifugal force to achieve the crushing effect. The fine powder is separated and collected by the airflow classifier.

      Typical structure: It consists of a main machine, an analyzer, a pipeline system, a cyclone powder collector, a motor, etc., and can be equipped with dust removal and noise reduction equipment.

      Technical origin: It was invented by the Raymond Company in the United States in the early 20th century. After several upgrades, it has become the mainstream equipment for non-metallic mineral processing.

YGM High-Pressure Grinding Mill is an advanced powder processing equipment based on high-pressure suspension roller grinding technology. It is mainly used for medium-fine powder grinding of medium-hardness and below materials (Mohs hardness ≤ 9.3), and is widely used in mining, building materials, chemical industry,metallurgy, and other fields.

​​Core definition points:

      Adopting a high-pressure spring booster system, by enhancing the grinding pressure of the grinding roller on the material (30%-50% higher than the traditional Raymond mill), a more efficient and finer crushing effect is achieved.

      The material is subjected to multi-layer grinding + airflow classification between the grinding roller and the grinding ring, and the finished product fineness can be flexibly adjusted within the range of 80-425 mesh.

MTW European Trapezium Grinding Mill is a medium-to-large industrial grinding equipment designed with advanced European technology. It is mainly used for grinding non-metallic minerals (such as limestone, calcite, barite, talc, etc.), and is suitable for building materials, chemical industry, metallurgy, and other fields.

Main features

Trapezium grinding roller and grinding ring design

      • Adopt curved trapezium grinding roller and annular grinding track to increase the grinding contact area, improve grinding efficiency, and reduce energy consumption.

      • The number of grinding rollers is usually 4-6, and the grinding force is adjusted by the hydraulic pressure system to adapt to materials of different hardness.

High-efficiency grading system

      • Built-in turbine classifier can accurately control the fineness of the finished product (adjustable within the range of 80-400 mesh), avoid over-crushing, and ensure particle uniformity.

Energy saving and environmental protection

      • Adopting variable frequency speed regulation and a centralized dust removal system (such as a pulse bag dust collector), it complies with European CE environmental protection standards, and the dust emission concentration is less than 30mg/m³.
