The shaftless trommel is changed from the shaft trommel, and the difference with the shaft trommel is that the screening surface of its internal structure is more barrier-free. The shaftless drum screen can be placed in the cleaning pipeline, which reasonably improves its cleaning effect and further improves the efficiency of screening. It gets rid of the problem that the circular vibrating screen and the linear screen are not connected when screening relatively wet materials, improves the productivity and reliability of the screening system, and has been recognized by the majority of users.
The drum screen is composed of five parts: an octagonal drum, a frame, a funnel, a reduction motor, and a motor. It is a traditional screening equipment. After the crushed material enters the inside of the drum, the material is screened by the function of the drum overturning. Sieve out one by one through different mesh screens. After the different materials are screened, they fall into the belt conveyor through the funnel and are sent to the finished product area.
The shaftless drum screen has a simple and reliable structure, stable operation, good sealing performance, no pollution, very low noise, relatively fine classification, large sorting ratio, very high production capacity, relatively accurate sorting, very low failure rate, and convenient maintenance And other advantages, it is very suitable for the classification of sand and gravel plants.
The scope of application of the shaftless drum screen: it can screen various materials and moist materials such as coal, coke, white ash, etc. The oversized material is less than 100, the middle 10-50, and the finer material can reach 3 the following.
What problems should be paid attention to when using shaftless drum screens?
1. The voltage must be stable. If the voltage is high and sometimes low, it will cause the linear vibrating screen generator to be unstable and cause the transducer to burn out.
2. When working, the transducer needs to be tightened, so that no dust can enter the transducer of the shaftless roller screen. If dust enters the transducer unintentionally, it will cause the transducer. Burn out.
3. There is no load on the grid frame, which means that when the grid frame is not stretched, the power supply of the shaftless drum screen cannot be turned on first, otherwise, the power supply will be overcurrent, the grid frame and the transducer will be damaged.
4. Shaftless drum screens cannot be operated for a long time under the condition of exceeding the rated current. If they operate under the condition of exceeding the rated current for a long time, the transducer will be burnt out.
5. The transducer on the power supply of the shaftless trommel needs to be matched with it. If a generator that does not match it is used, the transducer will burn out.
