Lasta SD Details

1. Filter plate pack close
After activating the start switch, the hydraulic power pack pumps oil to the hydraulic cylinder which clamps all the filter plates together and forms each filtration chambers.

2. Filtration
Slurry is pumped via the feeding port to the filtration chambers. The solids remain and the filtrate passes through the filter cloth.

3. Compression
Pressurized water is jnjected behind the diaphragms. The filter cake is compressed and further dewatered.

4. Filter Plate Pack Open
After completion of filter cake compression process, the hydaulic pump operates automatically for driving cylinder and opening the filter plate pack.

5. Cake Discharge
When all the filter plates are opened, all the filter cloths containing discharged cake travel downwards and filter cake is discharged.

6. Filter Cloth Washing
After the filter cakes are discharged, the cake doors close and all the filter cloths are washed on the return travel.

Cake wash system

Wash water passes through the filter cake, foreign substances in cake are removed or precious substances in case are extracted.
Normal cake wash: Wash water is fed into each chamber from the top feeding port, passing through the cake and discharged via the filtrate port.
