The Raymond Mill is a highly efficient milling equipment widely used in the mining, building materials, chemical, and metallurgical industries. Its primary function is to grind bulk and granular materials into fine powders, typically with a fineness between 80 and 325 mesh. It features a compact structure, easy operation, low energy consumption, and stable output. […]
Fineness:
80–325 mesh (adjustable)
Capacity:
10–40 tons/hour
Scene:
The equipment is suitable for building materials, metallurgy, electric power, chemical industry, transportation, mining and other industries. It can grind various non-flammable and explosive materials with a Mohs scale of less than 7, such as gypsum, talc, illite, calcite, limestone, coal gangue, barite, dolomite, manganese ore, chromium ore, potassium feldspar, iron ore, kaolin, bentonite, etc.

Grinding Roller
Core Functions:
Grinding
Fineness adjustment
Efficiency enhancement
Wear resistance
Uniformity
Grinds the material into powder by rotating extrusion. The pressure can be adjusted to flexibly meet various fineness requirements.
Material: High-hardness wear-resistant material
Advantages: Wear-resistant and stable with long service life. The material is evenly stressed during grinding to avoid over-grinding or under-grinding, ensuring uniform particle size.
Grinding Ring
Grinds with the grinding roller at high speed to make large pieces of material into fine powder.
Core Functions:
Firmly supports the grinding roller during operation
Guides the grinding roller to roll along a stable trajectory
Shovel
The main function is to scoop up the material entering the mill and send it between the grinding roller and the grinding ring for grinding.
Material: Usually made of wear-resistant material to resist the wear of abrasives
Analyzer
Used to control the fineness of the finished product. The particle size of the powder is controlled by adjusting the speed of the analyzer.
Blower
Blows the ground powder into the analyzer for sorting.
Cyclone Collector
Used to collect qualified finished powder.
Pipeline System
Connects various components to ensure smooth airflow.
