Great Wall is a large manufacturing company of large mining machinery

Great Wall is a large manufacturing company of large mining machinery such as various type of crushing machines. Our products include not only traditional stone jaw crusher and mineral impact crusher, but mobile construction station, gyratory cone crusher, powder grinding mill, ball mill machine, magnetic drum separator and dryer drum which are various in models and comprehensive in specifications.

The ball mill grinder produced by Great Wall is improved according to the environmental protection requirement of the new time and it adopts full diameter double-row self-aligning roller bearing with convenient maintenance and high efficiency. The discharging mouth adopts cone structure and grinding balls with a relatively small diameter are used, so that the grinding granularity of materials is fine. At the same time, new type of steel materials is used, thus greatly reducing the waste pollution of the equipment. In the working process of ball grinder, a drum feeder machine is used, so that there is no inertia impact and the machine can run stably, thus reducing maintenance time.

When the ball mill is working, there are many parts touching with each other. To ensure the friction parts in lubrication is vital to the ball mill’s service life. Thus it will avoid the dry friction. It has been proved that the machine temperature will increase quickly in a short time; the heat will smelt the parts of the ball mill. Unfortunately, the machine will stocked even it can’t work anymore. Then we must guarantee the friction position have good lubrication. The oil flows to the frication part to cover the frication surface to enhance the movement of the machine. Oil plays an important role in the working process. Ball mill bearing seat is installed, should check the bearing seat of the cooling water hose and the end cover shaft neck and check whether a collision, thermal resistance and shaft neck contact is good .
