A double snail Screw Compactor is a new product developed by LD Systems. The double compactor is able to receive the dump from 2 Back Rakes, saves space in small stations and eliminates the need to use a conveyor belt to transport the dump between the Rakes and the compressor. Our double compactor significantly reduces the volume of the dump by 60% to 70%.

Double Screw Compactor -
Operation mode

The compressor motor is automatically activated when the back-up operation is completed. When the backing ends what the ascent, the waste falls to the conveyor belt and from there to the compressor. The snail leads the waste to the special compression tube where 3 actions occurs: waste is being washed, compressed and pressed. Liquids flow out through special holes in the pressing pipe and are being drained through a 3″ diameter at the bottom of the basin which prevents the possibility of blockages. 

The pressure from the snail, only then can the foreign body be removed and the compressor returned to the “automatic” position and to continue normal and continuous activity. Our tin Compactor leads the waste into a compression tube where 3 operations are being carried out: waste is being washed, compressed and pressed. Liquids flow out through special holes in the pressing pipe and are being drained through a 3″ diameter at the bottom of the basin.
The compressed Sludge is driven upward through an exit hole of 10″ diameter. At the exit funnel there is a top cover for easy cleaning and blockage removal if necessary.
