Raymond Mill (Raymond Mill) is a common grinding equipment, suitable for ore, building materials, chemical industry and other fields of grinding and grinding process. The Raymond mill uses the relative motion between the grinding roller and the grinding ring to grind and break the material, and then classifies the material according to the particle size through the classification function of the analysis machine, and finally collects and extracts the required finished powder.

Basic structure:

Main structure: The main structure of Raymond mill includes the main machine, the analytical machine, the fan, the pipeline equipment and the electronic control system.
Grinding device: the main machine is equipped with a set of grinding device, generally including the main shaft, grinding roller, grinding ring and grinding knife and other parts. A certain pressure is formed between the grinding roller and the grinding ring to grind and break the material.
Grading device: The analyzer is used to control the particle size of the material and grades the material according to the size of the particle size. There is a set of impeller and screen inside the analytical machine, and the fineness of the material is controlled by adjusting the speed and air volume of the impeller.
Air duct system: Raymond Mill is equipped with fans and piping equipment for conveying materials and regulating air flow inside the mill.

How it works:

Feeding and grinding: The material enters the grinding device of Raymond Mill through the feed port and is ground and broken by the extrusion and friction of the grinding rolls and grinding rings. The grinding roller rotates under the drive of the main shaft, and the material is finely ground by the grinding knife.
Grading and discharging: After grinding, the material enters the analytical machine for grading. By adjusting the speed and air volume of the impeller, the finer particles are discharged through the screen, while the coarser particles are re-fed into the grinding device for re-grinding.
Circulating and circulating air: In order to control the temperature and humidity of the mill, Raymond mills usually use circulating air systems. The fan introduces a part of the gas into the mill, forming an air circulation, which takes away the heat and fine powder, and maintains the temperature and humidity inside the mill.
Discharge and collection: After grading, the finer material is blown into the air duct system by the wind, and is transported through the pipe to the material collection device, and finally forms the finished powder.
Adjustment and control: Raymond mill is usually equipped with an electronic control system, which can adjust and control the operating parameters of the mill. The grain size, output and quality of the product can be controlled by adjusting the feed amount, air volume, impeller speed and other parameters.
