The difference between vertical roller mill and ball mill The ball mill is generally composed of a horizontal cylinder, a hollow shaft for feeding and discharging, and a grinding head. The cylinder body is provided with an abrasive body, the cylinder body is made of steel plate, and the steel lining plate is fixed with the cylinder body, and the grinding body is generally a steel ball, and Load into the barrel according to different diameters and proportions. CHAENG GRM vertical roller mill mainly consists of separator, grinding roller, rocker arm, grinding disc, upper casing, frame, transmission, dry oil lubrication device, gas sealing pipe, limit device, water spray system, hydraulic pressure The device and the pipeline, the grinding and rolling device, the pipeline, the rolling device and the like are composed of components. Ball mill process features: (1) The structure is more complicated, horizontal horizontal installation, large floor area, and high capital investment; (2) There are many system equipments, maintenance points are scattered, many items are repaired, time is much, the frequency of shutdown is high, the weight of single rolls is large, and maintenance is difficult; (3) The ball mill system has complex process flow and is not suitable for raw materials with large moisture content. It is difficult to adjust the product variety, and the adaptability

of the grinding material is poor; (4) The system power consumption is 80kwh/t, and the roller press system has a large circulation amount, and it has to be transported by the belt conveyor and the lifting conveyor, so the system is dusty; (5) System operation rate: 85%-90% Vertical mill process features: (1) The structure is simple, the vertical mill installation is adopted, the floor space is small, and the capital investment is small; (2) The auxiliary equipment of the whole vertical grinding system is less, the probability of stopping is small, the repair and replacement of the grinding roller...

Although the vertical mill has high equipment cost, the vertical mill integrates grinding, grading and drying, and the equipment is compact, simplifying the process flow, saving capital investment, and having strong drying ability. It can be dried by using auxiliary heat source, high grinding efficiency, power consumption can be reduced by more than 30%.
