The LSF sand-water separator is suitable for sand-water treatment in the grit chambers of urban sewage treatment plants. It is mainly used in conjunction with the cyclone grit chamber sand remover or the bridge suction sand remover to further separate the discharged sand-water mixture.

The equipment is shaftless spiral. The sand-water mixture is input from the upper part of the separator. The sand and gravel settle by gravity in the sand-water separation tank and are gradually pushed along 25°U-shaped channel to the outlet by the rotation of the shaftless helical body. After falling into the receiving cylinder, the separated water is discharged from the overflow outlet of the separation tank to improve the operating environment and facilitate transportation.

1. Drive unit adopts shaft-mounted parallel shaft helical gear reducer, compact structure, smooth and safe operation;

2. The recovery rate after separation of particles larger than 0.2mm can reach 96 percent;

3. The U-shaped groove is lined with strong wear resistance, long service life and easy replacement;

4. The whole machine operates in a fully enclosed manner, the environmental conditions are good, the frame is fixed with expansion bolts, no embedded parts are needed;

5. The equipment can be interlocked with the supporting equipment for convenient control and can also be equipped with a local control box by itself.
