In cranes, tower cranes, truck-mounted cranes and other lifting equipment, the slewing bearing plays a very important role. It can form a connection between the chassis and the upper structure of the machine, allowing the crane to rotate 360 ​​degrees, while bearing the axial, radial and direction and overturning moment. The open design of the […]

We all know that when some machinery and equipment need to generate excitation force, if the machine itself does not have this function, it needs to add some vibration devices. The vibrating screen needs to use mechanical vibration to screen materials. Therefore, vibration The screen exciter has become one of the important components of the […]

Forging is the use of forging pressure on metal blank products by forging machines to plastically deform the processed forgings to achieve specific mechanical properties, shapes and sizes. This is an important metal plastic processing method adopted by many forging manufacturers. Many people know about forging, but they don’t know much about the forging process. […]

High precision is the main feature of crossed roller bearings different from ordinary bearings. Therefore, in the process of use, more attention should be paid to avoid affecting the working life of the bearing. Correct use of crossed roller bearings is an important condition for reducing bearing failures and extending bearing life, so how to […]

High pressure roller mill is a new type of grinding equipment developed on the basis of roller press for cement in recent years. Mines increase the specific surface area for fine grinding. The high pressure roller mill has the characteristics of high production efficiency, large crushing ratio , low power consumption, significant energy saving and […]
