The best shaftless roller screen is a kind of machine which is widely used in sorting technology. The roller screen is mainly composed of motor, reducer, roller device, frame, sealing cover and inlet and outlet. Is through the particle size to control the garbage sorting, sorting accuracy is high. The cylinder of the shaftless roller screen is generally divided into several sections, depending on the specific situation, the sieve holes are arranged from small to large, and the aperture of the sieve holes on each section is the same.
Drum screening machine is easy to seal dust, small maintenance, simple maintenance and long service life. The shaftless roller screen is a device frequently used in the classification of refractory materials, coal, river sand, and gravel blocks.
Design Key Points of shaftless roller screen machine:
The traditional transmission mode is chain-type and gear-type. It is not common to wear the roller because of the large torque of the chain transmission mode. The production cost is greatly increased by making the front and rear cylinder rings. The gear transmission is the most practical transmission mode of shaft-less roller screen equipment.
Chain drive is usually made in the end of the shaftless roller screen machine can be added to the roll, but the effect is not good, this way is difficult to avoid roller side plate wear, because the chain drive produces a relatively large resultant force, to roll resistance is unable to reset the shaftless roller screen machine. And the gear transmission of the shaft-less roller screen is driven by the gear between the formation of natural force, there is no external force on the drum distortion, the shaft-less trommel will run in a relatively stable environment, at the end of shaft-less trommel to increase the roller block is a better way.
The surface treatment of shaftless roller trommel machine is very important because the surface treatment of roller is very important. Some of them do not use rubber treatment, but use the hard surface of steel wheel to drive the roller directly. This will increase the noise of the equipment and reduce the service life of the shaftless trommel machine.
Operation maintenance of the shaft-less roller screen machine:
The shaftless roller screen machine is reliable in operation and has easy maintenance. The following points should be noted :
1. The shaft-less roller screen machine must be opened first, then the feeding equipment should be opened.
2. Three days before operation, the cage drum screen fasteners should be checked every day, if loose should be fastened in time. In the future, the cage drum screen fasteners can be checked and handled regularly (weekly or half month).
3. The bearing seat, gearbox should check the lubrication condition regularly, and refuel and change oil in time. Large shaft bearings using No .2 lithium grease, normally, every two months add grease, the amount of injection should not be too much, otherwise easy to cause bearing overheating. Each bearing shall be cleaned and inspected once a year.
4. The equipment long-term stop (more than 30 days) restart should be the motor insulation shake test to avoid motor burning.
