Development and Application of Raymond Mill

Raymond mill is a type of grinding equipment commonly used in the field of mineral processing, building materials, chemicals, and metallurgy. It has a long history and has been continuously improved and developed over time. Here are some developments and applications of Raymond mill:

1. Development history: The Raymond mill was first invented by a German engineer named Max von Gruber in the late 19th century. Over time, it has undergone continuous improvements and developments, including the introduction of a variety of grinding rollers, grinding rings, and other components.

2. Application range: Raymond mill can be used to grind various non-metallic minerals with Mohs hardness below 7 and humidity within 6%, such as limestone, calcite, marble, kaolin, bentonite, barite, feldspar, fluorite, gypsum, etc.

3. Structural features: The main components of Raymond mill include the grinding roller assembly, grinding ring, blade system, motor, and other parts. The grinding roller assembly is suspended on the grinding roller hanger through a cross-arm shaft, and the grinding roller can rotate around the central axis of the grinding ring under the action of centrifugal force.

4. Working principle: The material to be ground is fed into the grinding chamber of the Raymond mill through the feeding device, and the grinding roller rotates at a high speed to crush and grind the material. Then, the ground material is transported to the classifier through the air flow, and the fine powder is collected by the dust collector.

5. Advantages: The advantages of Raymond mill include high grinding efficiency, low energy consumption, low noise, and relatively small floor space.

Here is a table summarizing the development and application of Raymond mill:
