Raymond Mill Parts – Components

Raymond mill is a commonly used grinding equipment, primarily applied in the mineral, chemical, and construction industries for non-flammable and non-explosive materials.

The key components of the Raymond mill are made of high-quality steel, and the wear parts are made of high-performance wear-resistant materials. This ensures high wear resistance and reliable operation of the entire machine.

The main parts of the Raymond mill include gears, blades, air ducts, grinding devices, grinding rollers, grinding rings, and roller hangers. These parts are located in different positions and play different roles. Below, we will take a detailed look at each part.

• Gears The gears are the main transmission components of the Raymond mill. Due to the high speed of the grinding process, the internal gears can easily wear out over time. To avoid affecting production, they need to be repaired and replaced promptly.
• Blades The blades are wear parts that continuously lift materials into the grinding rollers and rings for grinding. Because they are in constant contact with materials, they wear out easily. The blades consist of a blade disc and a blade cylinder. In smaller Raymond mills, these are connected together, while in larger models, they are connected by screws.
• Air Duct System The air duct system of the Raymond mill features a curved design for a simple and reliable process. This design ensures smooth airflow and effective material dispersion at the outlet, preventing blockages and improving the efficiency of the fan.
• Grinding Device The grinding device includes a suspended base, a carriage, an arm assembly, and a grinding tool. The arm assembly, which consists of multiple joints and a movable arm, is fixed to one side of the suspended base. It supports the grinding tool, which includes a motor and transmission device for rotational grinding. The lower end of the grinding tool features a grinding disc with a grinding stone at the bottom.
• Grinding Rollers Grinding rollers are crucial components and are prone to wear. They need to be replaced periodically based on the type of material, usage frequency, and operational conditions.

• Grinding Rings Grinding rings are directly in contact with the materials and wear out easily. To improve quality and reduce wear, they are usually made from two types of materials: 65Mn (65 manganese) and Mn13 (13 manganese).

• Roller Hangers The roller hangers are essential supports for the entire grinding system. They support the entire mill and the roller assembly, including high-pressure springs. During operation, the main shaft drives the roller hangers, enabling the rollers and rings to rotate and grind materials.
