Drive Selection For Large Loesche Vertical Roller Mills
jun 15, 2016 cement international 22016 vol. background to drives of vertical roller mills the drive of a vertical roller mill essentially the mill gearbox has to fulfill two tasks: the first is to reduce the speed of the electric motor to the selected mill speed and to transmit the torque created by the motor.address 304-a, shanthi gears road, singanallur, coimbatore 641 005, tamil nadu, india. phone No 422 fax 422vertical rolling mill is disclosed wherein a means for driving the mill rolls is comprised of a rigid vertical spindle having universal joints and couplings at either end which is detachably connected to the mill roll at its lower end and connected to a splined driving member at its upper end. the splined driving member consists of two parts.vertical mills flexible mills with integrated separator. the vertical mill enables high energy economy, and convinces with low specific wear values. drying of the feed material, grinding, separating, and material transport take place inside the mill. It is thus especially well suited for grinding products with high proportions of wet components.
Vertical Cement Mill Vertical Roller Mill Buy Cement
the vertical cement mill is large-scale cement grinding machine. with advantages of energy-efficient and stable quality, vertical roller mill is widely applied to many industries, such as cement, power, metallurgy, chemical and nonmetallic mining industry and etc. As a typical type of cement mill, vertical cement mill set crushing, drying, grinding, grading transportation in one, it grind bulk the mill is driven by an electric motor via a flexible coupling and the mill gearbox via a vertical output flange segmental thrust bearing at the top of the gearbox absorbs the grinding forces. before the mill motor is started, the grinding rollers are lifted hydraulically from the grinding track. the millstructure of vertical roller mill. the combined classifier improves the powder selection efficiency. It is not necessary to distribute material on the grinding plate before start-up. the roller can be lifted up and down automatically and start without load.
