whats the difference between roller screen with & without shaft? - jxsc machine

The roller screen with shaft is a special screening equipment developed for power plant, coking plant, building materials, metallurgy, chemical industry, mining and other industries. It overcomes the screen sticking and blocking problems of various vibrating screens when screening wet materials, and improves the output and reliability of the screening system. It is suitable for screening materials of various properties, as well as damp and easily blocked materials such as coal, coal gangue, coke, quicklime, etc.,

The drum unit is tilted to the frame. The motor is connected with the drum device through coupling through the reducer, and the driving roller device rotates around its axis. When the material enters the drum body, the material on the screen surface is turned over and rolled due to the tilt and rotation of the drum device. So that the qualified materials- material size is smaller than the screen size(products under screen) are discharged through the discharge port at the bottom of the back end of the drum. And the unqualified materials material size is larger than the screen size(products on screen) are discharged through the discharge port at the end of the drum. Due to the material turning and rolling in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking. The principle structure of roller sand screen, drum screen separator and roller screen is almost the same, which is the difference of peoples understanding and calling.

The roller device of the non axial drum screen is inclined to be installed on the frame, and the structure design of the non central shaft is adopted. The motor drives the pinion engaged to rotate with the big gear of the drum or the chain is engaged with the gear on the drum. The motor drives the chain transmission or the roller is placed on two supporting rollers, and the motor drives the idler drive. The drum device is driven by the driving device. When the material enters the drum device, the material on the screen surface is turned over and rolled due to the tilt and rotation of the drum device. So that the qualified materials material size is smaller than the screen size(screen down products) are discharged through the discharge port at the bottom of the back end of the drum. And the unqualified materials material size is larger than the screen size(screen products) are discharged through the discharge port at the end of the drum. Due to the material turning and rolling in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from blocking.

Compared with the drum screen with central shaft, the structure of the drum screen without shaft is simpler. At the end of the drum screen close to the vibration motor, several steel bars are welded around the drum evenly, and the other end of the steel bars is converged to the central axis of the drum. After being fixed, the vibration motor is connected through gears. When the vibration motor is started, the drum will rotate.The same screening principle as roller screen with shaft. Shaftless roller screen is relatively more material saving, screening material space is larger, when the drum failure maintenance is relatively easy, so the use of shaftless roller screen is also very much. For example, for domestic waste pretreatment, it can screen out the required waste. The advantage of shaftless is that it can avoid the entanglement of materials, and the screening efficiency is relatively high.
