Anti-wrap dry and wet waste separation trommel screen

The shaftless drum screen has obvious advantages over the same type of shaft drum screen in the screening and sorting process. The role of the shaftless drum screen in the separation and screening of municipal solid waste is irreplaceable. The shaftless drum screen has a strong anti-winding property and high precision of household garbage sorting. The sieve drum of the shaftless drum screen adopts a grading design, and the screen aperture can be replaced as needed, and one machine can be used for multiple purposes.

Working principle of shaftless waste drum screen

The shaftless drum screen drum unit is mounted on the frame at an angle and is designed without a central shaft structure. The motor drives the pinion gear to rotate with the large gear of the drum or the chain and the gear on the drum. The motor drives the chain drive or the roller is placed on the two rollers, and the motor drives the roller to drive. The roller device rotates under the driving of the driving device. After the material enters the roller device, due to the tilting and rotation of the roller device, the material on the screen surface is turned over and rolled, so that the qualified material (the product under the sieve) passes through the bottom of the rear end of the roller. The material is discharged, and the unqualified material (the product on the screen) is discharged through the discharge port at the tail of the drum. Due to the turning and rolling of the material in the drum, the material stuck in the screen hole can be ejected to prevent the screen hole from being clogged.

This trommel screening is suiting for separation of wet or dry waste

For dry waste, the trommel screen is turned over to make the material and the screen effectively contact, and the dry material can be quickly screened.
For wet waste, the machine drives the wet material to roll so that the materials are thoroughly mixed with the air. Making them drier, facilitating screening and reducing the blockage of the screen.

Choosing a suitable screening and sorting equipment can have a good effect on the recycling and recycling of garbage. The distribution of domestic garbage is extremely uneven, and the types of garbage are various. When the vibration frequency is high, the deposition rate decreases, but there is still a siltation. When the vibration frequency is high and the deposition rate is low, since the vibrating screen does not have the effect of tumbling domestic garbage, large materials in the domestic garbage are wrapped in small materials. , resulting in reduced sorting efficiency of the vibrating screen. From the actual use of various sieve machines, the drum screen is the best choice. The sieve hole can be selected according to the specific content of the sorted domestic garbage, a strip mesh hole, a circular sieve hole and the like.
