Heavy Duty Three Row Roller (13 Series) without Gear Slewing Ring Bearing for Mining Equipment Rotary Drum Screen
The drum screen mainly consists of slewing bearing, drum device, frame, sealing cover, inlet and outlet.The roller device is inclined to be mounted on the rack. The motor is connected with the roller device through the coupling through the coupling, driving the drum device to rotate around its axis.When the materials enter the cylinder device, because of roller gear tilt and transhipment, flip and rolling material on the surface of the sun, make the qualified material (undersize) after roller end at the bottom of the discharging mouth eduction.As the material is flipped inside the drum, roll the material in the sieve hole to prevent the hole plugging.
The three row roller slewing bearing has three seat rings,which separate the upper,lower and radial raceways,
it made each row of the roller's load capacity can be specified and can bear different loads simultaneously.
The capacity load is the largest one compare with the other three models.Due to the large size in axial and
radial dimension the solid structure, it is specially suitable for the heavy duty machinery such as wheeled
excavator,wheeled crane, ship crane,ladle turrets and the heavy duty mobile crane etc.
