Raymond mill is a common milling equipment, mainly used in non-flammable and explosive mining, chemical, construction and other industries.

The important parts of the Raymond mill are made of high-quality steel, and the wear-resistant parts are made of high-performance wear-resistant materials. The whole machine has high wear resistance and reliable operation. The accessories of Raymond mill mainly include gears, shovels, air ducts, grinding devices, grinding rollers, grinding rings, plum blossom stands and other accessories, and the positions of different accessories are different, and the roles they play are also different. Let's take a look at the details of each accessory in detail.

 

 

The gear is the main transmission part of the Raymond mill. Since the Raymond mill rotates very fast when grinding, the internal gears can easily damage the gear groove surface after long-term operation. In order not to affect production, it should be repaired and replaced in time.

 

 

The blade of the Raymond mill is a vulnerable part. During the continuous rotation of the machine, the material is shoveled and thrown between the grinding roller and the grinding ring for grinding. Due to prolonged contact with materials, it is easy to wear. The shovel is composed of a shovel disc and a shovel cylinder. Generally, the shovel disc of the small-scale Raymond mill is connected with the shovel cylinder, while the shovel disc of the large-scale Raymond mill is separate. It is connected with the blade barrel by screws.

 

 

 

The air duct system of the Raymond mill adopts a curved surface design, and the technological process is simple and reliable. Improve fan utilization.

 

 

The grinding device consists of: a suspension base, a car, a crank arm group and a grinding tool, the crank arm group is fixed on a selected side of the suspension base, and consists of a plurality of joints and movable arms The free end is combined with the grinding tool, and a motor and a transmission device are set to drive the grinding tool to engage in rotary grinding, and the grinding tool is connected to the crank arm set, and its lower end has a grinding disc, and the bottom of the grinding disc is combined with a grinding stone.

 

 

The grinding roller is one of the important parts of the Raymond mill, which is easy to wear. Under normal circumstances, the Raymond mill needs to be replaced after a period of use, which is determined according to the customer's raw materials, frequency of use and whether it is operated.

 

 

The grinding ring is an accessory that is in direct contact with the material and is easy to wear. In order to improve the quality of the grinding ring and reduce wear, two materials are generally used in manufacturing, namely 65Mn (65 manganese) and Mn13 (13 manganese).

 

Raymond Mill Grinding Ring

 

 

The plum blossom stand is an important support for supporting the entire grinding system of the Raymond mill. The entire mill and grinding roller assembly, including the high-pressure spring, are all installed on the plum blossom frame through the cross arm shaft. When the mill is running, the plum blossom frame is driven by the main shaft, and then the rolling of the grinding roller and the grinding ring is realized.
