Raymond Mill

• Features
• Product data

Raymond mill is a vertical roller mill that adopts the mature principle of suspended roller rolling and crushing. It drives the grinding roller to rotate through the central vertical shaft, causing the grinding roller to roll inside the annular grinding ring, achieving the rolling and grinding of materials. This equipment integrates grinding, grading, and conveying, and is a classic solution in the traditional industrial grinding field. It has stable performance and wide applicability.

Core working principle

The workflow of Raymond mill is an efficient closed-loop system:

Feeding and Rolling: The material to be processed is evenly fed into the mill by the feeder and crushed between the grinding roller and the grinding ring.

Wind power enhancement and grading: The crushed material is blown up by the upward airflow generated by the bottom fan of the system and enters the classifier above.

Precision classification: The high-speed rotating classifier precisely sorts the powder by adjusting the speed. Qualified fine powder passes through the airflow, while unqualified coarse powder is thrown back into the grinding chamber for re grinding.

Finished product collection: The dusty airflow enters the cyclone collector, where the majority of the finished powder is efficiently separated and collected. Purification cycle: The purified airflow is circulated back to the main unit through a fan, forming a negative pressure closed-loop cycle to ensure no dust overflow.

Highlight product advantages

Efficient and stable: Mature mechanical structure design ensures that the equipment can operate continuously and stably for a long time, with low failure rate and low maintenance costs.

Particle size controllable: adopting an independent grading system, the fineness of the finished product can be flexibly adjusted within the range of 80-600 mesh to meet diverse needs.

High system integration: The whole machine has a three-dimensional structure, occupies a small area, and can be processed from block to finished powder in one go, with a high degree of automation.

Strong reliability: The core grinding components (grinding rollers, grinding rings) are made of high wear-resistant alloy materials, treated with special processes, and have a long service life.

Environmental protection and energy conservation: Adopting closed-loop negative pressure operation, effectively controlling dust emissions, creating a clean working environment that meets environmental requirements.

Typical application areas

Raymond mill is widely used in non-metallic minerals, building materials, metallurgy, chemical and other industries, suitable for various non flammable and explosive materials with Mohs hardness below 7 and humidity below 6%, such as:

Non metallic minerals: calcite, marble, limestone, barite, fluorite, kaolin, etc.

Building materials and chemical industry: gypsum, talc, feldspar, phosphate ore, activated carbon, etc.

Other fields: Grinding and preparation of glass and ceramic raw materials.
