The raceway of the slewing bearing generally needs to be heat treated. In the heat treatment process, because the diameter of the raceway circle of the slewing bearing is relatively large, flame surface quenching is usually used. The method is to use acetylene to heat the surface of the workpiece to be hardened and then add water […]
The vibrating screen is a screening equipment often used in the sand and gravel industry. It uses the exciting force generated by the exciter to screen the material, which is convenient for the next production of the material. However, the vibrating screen does not run continuously for 24 hours. When the production is not in use, the […]
Most industrial production requires burning coal to obtain a high-temperature production environment. In order to improve the combustion performance of coal, briquette is basically used. The briquette can better meet the needs of industrial production in terms of strength and durability. But not all the briquette pellets pressed by the briquetting machine can meet the requirements, and […]
